Conventionally, in the drainage port unit 7 in which the hole portion 14 is formed in the bottom plate portion 8 and the upper side of the hole portion 14 is closed by the thin portion 19, the water permeated from the void 20 of the thin portion 19 causes the hole portion 14. A technique has been proposed in which the water is discharged to the lower part via the same (see, for example, Patent Document 1).

Further, in general, when the road surface is molded from concrete or the like, a water gradient is provided on the road surface in order to prevent water pools due to surface water such as rainfall from forming on the road surface.

Japanese Unexamined Patent Publication No. 2012-172506

However, when surface water is drained due to a water gradient, the drainage is concentrated in a predetermined place (river, etc.), which may cause environmental problems such as flooding of the river.

In addition, when the road surface is molded from concrete or the like, the surface water does not soak into the ground below the road surface, which may cause environmental problems such as land subsidence due to lack of water in the ground.

Furthermore, apart from the above-mentioned environmental problems, there is also a request to make the concrete road surface horizontal, and in that case, a technology that balances the contradictory elements of drainage (prevention of puddle) and horizontality (of the road surface) is required. Will be.

In Patent Document 1, it is essential that the bottom plate portion 8 is made of porous concrete, and since it is related to the drainage port unit in the first place, it can be used when concrete or the like is driven into the road surface. is not it.

Therefore, an object of the present invention is to provide a road surface molding auxiliary member capable of easily molding a road surface capable of appropriately draining and storing surface water.

The present invention is a road surface molding auxiliary member used at the time of molding a road surface, in which a plurality of communication pipes made of a flexible material are arranged in a mesh pattern, and a plurality of first meshes of the mesh are arranged. A main body portion in which each of the through holes is formed, and a plurality of tubular portions each having a plurality of second through holes communicating with the plurality of first through holes and protruding from the main body portion. A space is provided between the plurality of communication pipes arranged in a mesh pattern, and the plurality of tubular portions project upward with the main body portion mounted on the mounting surface. The second through hole is formed by driving concrete, mortar, cement, or asphalt into a portion other than the second through hole on the main body portion placed on the above-mentioned mounting surface. Provided is a road surface forming auxiliary member characterized in that a drainage channel is formed by the first through hole and the communication pipe.

According to such a configuration, by driving a road surface molding material such as concrete into a portion other than the second through hole on the main body portion, drainage is performed by the tubular portion (second through hole) and the first through hole. The road surface on which the road is formed is molded, and the surface water on the road surface is drained to the mounting surface through this drainage channel. As a result, surface water seeps into the ground below the road surface, and environmental problems such as land subsidence due to lack of water in the ground are suppressed. At this time, due to the presence of space, the flexible main body can be easily bent in response to non-landing, so that the strength of the main body (particularly the communication pipe) decreases due to the influence of non-landing. , It is suppressed that the function as a drainage channel is impaired. Further, by using the road surface forming auxiliary member, it is not necessary to provide a water gradient for drainage, so that it is possible to form a horizontal road surface. As a result, the surface water is prevented from being drained in a predetermined place, so that environmental problems such as flooding of rivers are suppressed and the demand for leveling the road surface can be met. It will be possible. Further, since the concrete or the like is driven onto the main body portion, the strength of the concrete or the like can be increased to the extent of the main body portion. Therefore, if a thick body is used as the main body, the strength can be further increased. Further, since the plurality of first through holes are communicated with each other by a communication pipe, even if the first through hole or the second through hole is clogged by dust or the like from the outside, the other first through hole is used. Since drainage is performed from the through hole or the second through hole, the drainage function is suppressed from being impaired. Further, since the surface water is dispersed throughout the main body by the communication pipe, the surface water can be evenly permeated into the ground. Further, when the amount of water in the ground is large, the water is stored between the communication pipe and the mounting surface, so that the amount of water in the ground is automatically adjusted.

Further, it is preferable that each communication pipe has a concave shape with an open lower portion.

According to such a configuration, the concave shape with the open lower part can be easily deformed in response to the non-landing, so that the strength of the communication pipe is reduced due to the influence of the non-landing, and the function as a drainage channel is impaired. Is further suppressed.

Further, it is preferable to further provide a rib portion extending in a substantially horizontal direction from the lower end portion of each communication pipe toward the outside of the communication pipe.

According to such a configuration, since the rib portion comes into contact with the mounting surface, it is possible to prevent the road surface forming material such as concrete from flowing from the space into the communication pipe.

Further, a rod-shaped reinforcing member can be hung and placed on the plurality of communication pipes, and the reinforcing member is held at a position on the communicating pipe where the reinforcing member should be placed. It is preferable that the groove is formed.

With such a configuration, it is not necessary to measure the position where the reinforcing member is placed or to separately fix the reinforcing member.

Further, a connection portion is formed at the end portion of the main body portion, and the connection portion formed at one end portion of the main body portion and the connection portion formed at the other end portion of the main body portion are different from each other. The communication pipes that can be connected to each other and are formed in the one main body portion communicate with the communication pipes formed in the other main body portion or the first through hole when the connection portions are connected to each other. It is preferably formed at the position.

According to such a configuration, since the road surface molding auxiliary member can be placed over a wide range, it is possible to store a large amount of surface water and to store the surface water in the ground over a wide range. It is possible to soak it evenly.

Further, according to another aspect of the present invention, a plurality of communication pipes made of a flexible material are arranged in a mesh pattern, and a plurality of first through holes are formed in the plurality of meshes of the mesh. It has a main body portion and a plurality of second through holes communicating with each of the plurality of first through holes, and has a plurality of tubular portions each protruding from the main body portion, and is arranged in the mesh pattern. A space is provided between the plurality of communication pipes, and the plurality of tubular portions are road surface forming auxiliary members that project upward with the main body portion mounted on the mounting surface. In the road surface molding method using the above, the step of mounting the road surface molding auxiliary member on the mounting surface so that the plurality of tubular portions face upward, and the second through hole on the main body portion. The present invention provides a road surface molding method characterized by comprising a step of driving concrete, mortar, cement, or asphalt into a portion other than the above.

With such a configuration, it becomes possible to easily form a road surface capable of appropriately draining and storing surface water.

Further, before the step of driving the concrete, mortar, cement, or asphalt, a first lid member for preventing the concrete, mortar, cement, or asphalt from invading into each tubular portion is provided. It is preferable to further include a step of attaching to the tubular portion and a step of removing the first lid member attached to each tubular portion after the step of driving the concrete, mortar, cement, or asphalt. ..

With such a configuration, it is possible to surely form a drainage channel on the road surface.

Further, the first lid member has an insertion portion inserted into the second through hole of the tubular portion and a chamfer forming portion extending upward and outward from the upper portion of the insertion portion. It is preferable to have.

Hereinafter, the road surface forming auxiliary member 1 and the road surface forming method according to the embodiment of the present invention will be described with reference to FIGS. 1 to 7.

The road surface molding auxiliary member 1 is used at the time of road surface molding with concrete, mortar, cement, or asphalt, and as shown in FIGS. 1 and 2, the main body portion 2 and the plurality of tubular portions 3 , Is equipped. Hereinafter, concrete, mortar, cement, or asphalt will be referred to as a road surface molding material.

The main body 2 is mounted on a mounting surface, and in FIG. 1, the main body 2 is mounted on a crushed stone Y (corresponding to a “mounting surface”) laid on the ground X. An example is shown. As the material of the main body 2, a flexible material is preferable, and a resin, a biodegradable plastic, or the like can be considered. However, when asphalt is used as the road surface molding material, it is preferable to use a heat-resistant material.

As shown in FIG. 2, the main body 2 is formed by arranging a plurality of communication pipes 21 made of a flexible material in a mesh pattern, and a plurality of first meshes of the mesh are arranged in a mesh pattern. Through holes 22 are formed. A space S is provided between the plurality of communication pipes 21 arranged in a mesh pattern.

In the present embodiment, as shown in FIG. 2, the plurality of communication pipes 21 are arranged so as to have a lattice shape, and the plurality of first through holes 22 are arranged in the vertical direction (paper surface in FIG. 2). It penetrates in the direction), and has a substantially flat plate shape (sheet shape) having an upper surface 23 and a lower surface 24 in the entire plurality of communication pipes 21.

Further, as shown in FIGS. 1 and 3, each communication pipe 21 has a concave shape with an open lower portion. As will be described later, water can be stored between the communication pipe 21 and the mounting surface, but in the present embodiment, the communication pipe 21 can store 10 liters or more of water as a whole. The size, number, etc. of 21 are set.

As shown in FIGS. 2 and 3, the main body portion 2 includes a rib portion 25 extending substantially horizontally from the lower end portion of each communication pipe 21 toward the outside of the communication pipe 21. Since the rib portion 25 extends substantially in the horizontal direction, when the main body portion 2 is placed on the mounting surface (crushed stone Y laid on the ground X), the rib portion 25 is laid on the mounting surface (ground X). It will come into contact with the crushed stone Y).

Further, the space S will be defined by the end portion of the rib portion 25. In the present embodiment, the space S is defined in a substantially quadrangular shape when viewed from the vertical direction (in FIG. 2, the rib portion 25 is shown only in the central portion in order to prevent complication).

As will be described later, a road surface molding material such as concrete, mortar, cement, or asphalt is driven onto the main body 2, and these road surface molding materials are placed on a mounting surface (ground) via the space S. Since it is hardened integrally with the crushed stone Y) laid on X, it is preferable that the space S has a size that allows the road surface molding material to pass through.

The size of this space S may be designed according to the road surface molding material used. For example, when ready-mixed concrete is used as the road surface molding material, the size of the gravel used for the ready-mixed concrete is roughly divided into two types, "maximum dimension 40 mm" and "maximum dimension 20 mm (25 mm)". 40 mm gravel is often used in civil engineering work, and 20 mm (25 mm) gravel is often used in construction work.

Therefore, when ready-mixed concrete is used, it is preferable that the space S has a size through which gravel can pass. For example, when 20 mm gravel is used and the distance between the ends of the opposing communication pipes 21 is 40 mm, the extension distance of each rib portion 25 is less than 10 mm as shown in FIG. It is possible to set it.

A rod-shaped reinforcing member such as a reinforcing bar can be hung and placed on the plurality of communication pipes 21, and the reinforcing member can be held at a position on the communicating pipe 21 where the reinforcing member should be placed. The groove 26 is formed (in FIG. 2, the holding groove 26 is shown only partially in order to prevent complication).

As shown in FIG. 2, a connection portion 27 is formed at the end portion of the main body portion 2, and as shown in FIG. 4, the connection portion 27 formed at the end portion of one main body portion 2A and another connection portion 27 are formed. The connection portion 27 formed at the end of the main body portion 2B can be connected to each other, and the communication pipe 21 of one main body portion 2A can be connected to the other main body portion 2B when the connection portions 27 are connected to each other. It is formed at a position where it communicates with the communication pipe 21.

It is preferable that the connecting portions 27 are provided on each side of the main body portion 2 and can be connected to other main body portions 2 (road surface molding auxiliary member 1) in a desired number on all sides. Various connection methods can be considered for the connection unit 27, but the connection unit 27 has some play when the main body units 2 are connected to each other so as to cope with the non-landing described later. It is preferable that it is designed so as to.

As shown in FIGS. 1 and 2, the plurality of tubular portions 3 have a plurality of second through holes 31 communicating with the plurality of first through holes 22, respectively, from the main body portion 2 (upper surface 23). Each is prominent. The plurality of tubular portions 3 project upward with the main body portion 2 mounted on the mounting surface. As the material of the tubular portion 3, a material having flexibility is preferable as in the main body portion 2, and a resin, a biodegradable plastic, or the like can be considered. However, when asphalt is used as the road surface molding material, it is preferable to use a heat-resistant material.

Further, as described above, a reinforcing member such as a reinforcing bar can be hung and placed on the plurality of communication pipes 21, but the height of the tubular portion 3 is preferably higher than the diameter of the reinforcing member. .. When the holding groove 26 is formed, the height of the tubular portion 3 may be higher than (diameter of the reinforcing member-depth of the holding groove 25).

Under the above configuration, a road surface molding material (concrete Z in FIG. 1) is driven into a portion of the main body 2 other than the second through hole 31 (up to the vicinity of the tip of the tubular portion 3 in FIG. 1). The road surface on which the drainage channel (second through hole 31 and first through hole 22) is formed is molded, and the surface water on the road surface is placed on the mounting surface (crushed stone Y and ground X) through this drainage channel. It is drained.

As a result, surface water seeps into the ground below the road surface, and environmental problems such as land subsidence due to lack of water in the ground are suppressed. Further, by using the road surface forming auxiliary member 1, it is not necessary to provide a water gradient for drainage, so that it is possible to form a horizontal road surface. As a result, the surface water is prevented from being drained in a predetermined place, so that environmental problems such as flooding of rivers are suppressed and the demand for leveling the road surface can be met. It will be possible.

Further, in the present embodiment, the first through holes 22 are communicated with each other by the communication pipe 21. As a result, even if the first through hole 22 or the second through hole 31 is clogged with dust or the like from the outside, drainage is performed from the other first through hole 22 or the second through hole 31. Therefore, the drainage function is suppressed from being impaired. Further, since the surface water is dispersed in the entire main body 2 and its surroundings by the communication pipe 21, the surface water can be evenly permeated into the ground. Further, when the amount of water in the ground is large, the water is stored between the communication pipe 21 and the mounting surface, so that the amount of water in the ground is automatically adjusted.

By the way, the surface on which the crushed stone Y or the like laid on the ground X is placed has some unevenness. Therefore, when concrete Z or the like is driven onto the road surface molding auxiliary member 1 mounted on the mounting surface, the main body 2 is surrounded by concrete in a state of being distorted due to non-landing or a state in which a load is strongly applied. It will be hardened by Z or the like, and the strength of the main body 2 may decrease.

However, in the present embodiment, a space S is provided between the plurality of communication pipes 21 arranged in a mesh pattern, and due to the existence of the space S, the flexible communication pipe 21 responds to non-landing. It can be easily bent. Therefore, the strength of the communication pipe 21 is lowered due to the influence of non-landing, and it is suppressed that the function as a drainage channel is impaired. Further, since each communication pipe 21 has a concave shape with an open lower portion that can be easily deformed in response to non-landing, the strength of the communication pipe 21 is also reduced, and the drainage channel is reduced. It is suppressed that the function as is impaired.

On the other hand, as described above, the communication pipe 21 has a concave shape with an open lower portion, and a space S is provided between the communication pipes 21, so that a road surface molding material such as concrete is driven into the communication pipe 21. At that time, the road surface molding material may flow into the communication pipe 21 from the space S, and the function as a drainage channel may be impaired.

However, in the present embodiment, the rib portion 25 extends substantially horizontally from the lower end portion of each communication pipe 21 toward the outside of the communication pipe 21, and the rib portion 25 extends from the mounting surface (ground X). Since it comes into contact with the crushed stone Y) laid in the space S, the road surface molding material is suppressed from flowing into the communication pipe 21 from the space S.

As shown in FIG. 5, the road surface molding material is driven in a state where the first lid member 4 for driving is attached (fitted) to the upper end of the second through hole 31 of the tubular portion 3. Is preferable.

As shown in FIG. 5, the first lid member 4 has a first insertion portion 41 inserted into the second through hole 31 of the tubular portion 3 and an upper and outer side from the upper portion of the first insertion portion 41. It has a chamfer forming portion 42 that spreads toward the surface. In FIG. 5, the first insertion portion 41 has a cylindrical shape having substantially the same diameter as the second through hole 31. Further, the chamfer forming portion 42 has a truncated cone shape, and has a structure in which the upper bottom thereof is attached to the upper part of the first insertion portion 41.

Further, it is preferable that after the first lid member 4 is removed, the second lid member 5 for finishing is inserted into the second through hole 31 of the tubular portion 3 to complete the road surface in that state.

As shown in FIG. 6, the second lid member 5 is smaller than the cylindrical second insertion portion 51 inserted into the second through hole 31 of the tubular portion 3 and the second through hole 31. It includes a top surface portion 53 in which a third through hole 52 having a diameter is formed. As a result, while suppressing objects other than surface water from falling into the second through hole 31, the second penetration of the tubular portion 3 through the third through hole 52 and the second insertion portion 51. Surface water will flow into the hole 31. As the third through hole 52, an appropriate size and shape (net-like or the like) may be used depending on the situation (a place where many people wearing high heels pass, a place where coins can be easily dropped, etc.).

Subsequently, a road surface forming method using the road surface forming auxiliary member 1 will be described with reference to the flowchart of FIG. 7.

First, the road surface molding auxiliary member 1 is placed on the mounting surface so that the plurality of tubular portions 3 are on the upper side (S1).

Subsequently, the first lid member 4 is attached to each tubular portion 3 (S2).

Subsequently, a road surface molding material such as concrete is driven into a portion of the tubular portion 3 on the main body portion 2 other than the second through hole 31 (S3). In this step, it is preferable to drive in an amount of the road surface molding material so that the entire chamfer forming portion 42 of the first lid member 4 is not filled.

Subsequently, the first lid member 4 attached to each tubular portion 3 is removed (S4). The first lid member 4 can be removed even if the road surface molding material is not completely cured, as long as it is cured to such an extent that the shape does not collapse.

Finally, the second lid member 5 is attached to each tubular portion 3 (S5) to complete the road surface.

As a result, a highly safe road surface is formed in which the tubular portion 3 does not protrude from the road surface.

Since the chamfer forming portion 42 of the first lid member 4 extends upward and outward from the upper part of the first insertion portion 41, concrete or the like driven into a position adjacent to the tubular portion 3 may be used. The road surface molding material is molded in a state of being chamfered along the shape of the chamfer forming portion 42, not at a right angle which is easily damaged, whereby the second lid member 5 is tentatively formed into each tubular portion 3. Even if it is not attached to, the road surface molding material molded at the position adjacent to the tubular portion 3 is prevented from being damaged.

As described above, in the road surface molding auxiliary member 1 according to the present embodiment, the plurality of tubular portions 3 communicate with the main body portion 2 (a plurality of communication pipes 21 arranged in a mesh pattern) and are arranged in a mesh pattern. A space S is provided between the plurality of communication pipes 21.

According to such a configuration, by driving a road surface molding material such as concrete into a portion other than the second through hole 31 on the main body portion 2, the tubular portion 3 (second through hole 31) and the first through hole 31 can be driven. The road surface on which the drainage channel is formed is formed by the through hole 22, and the surface water on the road surface is drained to the mounting surface through the drainage channel. As a result, surface water seeps into the ground below the road surface, and environmental problems such as land subsidence due to lack of water in the ground are suppressed. At this time, due to the presence of the space S, the flexible main body portion 2 can be easily bent in response to the non-landing, and therefore, due to the influence of the non-landing, the main body portion 2 (particularly the communication pipe 21) The strength is reduced and the function as a drainage channel is suppressed from being impaired. Further, by using the road surface forming auxiliary member 1, it is not necessary to provide a water gradient for drainage, so that it is possible to form a horizontal road surface. As a result, the surface water is prevented from being drained in a predetermined place, so that environmental problems such as flooding of rivers are suppressed and the demand for leveling the road surface can be met. It will be possible. Further, since the concrete or the like is driven onto the main body portion 2, the strength of the concrete or the like can be increased by the amount of the main body portion 2. Therefore, if a thick body portion 2 is used, the strength can be further increased. Further, since the plurality of first through holes 22 are communicated with each other by the communication pipe 21, even if the first through hole 22 or the second through hole 31 is clogged with dust or the like from the outside. Since drainage is performed from the other first through hole 22 and the second through hole 31, it is possible to prevent the drainage function from being impaired. Further, since the surface water is dispersed in the entire main body 2 by the communication pipe 21, the surface water can be evenly permeated into the ground. Further, when the amount of water in the ground is large, the water is stored between the communication pipe 21 and the mounting surface, so that the amount of water in the ground is automatically adjusted.

Further, in the road surface molding auxiliary member 1 according to the present embodiment, each communication pipe 21 has a concave shape with an open lower portion.

According to such a configuration, the concave shape with the lower part open can be easily deformed in response to the non-landing, so that the strength of the communication pipe 21 is reduced due to the influence of the non-landing, and the function as a drainage channel is reduced. The damage is further suppressed.

Further, the road surface molding auxiliary member 1 according to the present embodiment includes a rib portion 25 extending substantially horizontally from the lower end portion of each communication pipe 21 to the outside.

According to such a configuration, since the rib portion 25 comes into contact with the mounting surface (crushed stone Y laid on the ground X), the road surface forming material such as concrete is suppressed from flowing into the communication pipe 21 from the space S. Ru.

Further, in the road surface molding auxiliary member 1 according to the present embodiment, a rod-shaped reinforcing member such as a reinforcing bar can be hung and placed on the plurality of communication pipes 21, and the reinforcing member on the communication pipe 21 is placed. A holding groove 26 for holding the reinforcing member is formed at the position where it should be.

With such a configuration, it is not necessary to measure the position where the reinforcing member is placed or to separately fix the reinforcing member.

Further, in the road surface molding auxiliary member 1 according to the present embodiment, the connection portion 27 is formed at the end of the main body portion 2, and the communication pipes 21 formed in one main body portion 2A are connected to each other. Is formed at a position communicating with the communication pipe 21 formed in the other main body 2B or the first through hole 22 when the is connected.

According to such a configuration, since the road surface molding auxiliary member 1 can be placed over a wide range, a large amount of surface water can be stored and the surface water can be stored over a wide range. It is possible to soak it evenly inside.

Further, in the road surface molding method using the road surface forming auxiliary member 1 according to the present embodiment, after the road surface forming auxiliary member 1 is placed, concrete or the like is placed in a portion other than the second through hole 31 on the main body 2. Drive in the road surface forming material.

With such a configuration, it becomes possible to easily form a road surface capable of appropriately draining and storing surface water.
