Description

ENVIRONMENT-FRIENDLY BUILT-UP-TYPE REVETMENT BLOCK HAVING STRAW LAYER}

The present invention relates to a raft block (or a front block) to be installed on the slopes of rivers or cut sections of roadsides. The present invention relates to an environmentally friendly prefabricated revetment block that has a straw layer attached to it so as to be compatible with the surrounding natural environment stably.

Conventional patent documents in the art disclose various types of revetment blocks (or surface blocks), but existing revetment blocks (or surface blocks) are constructed on slopes of rivers or cut sections of roadsides. Since concrete, the main material, is exposed as it is, there are various problems in terms of environment friendliness.

In detail, the Japanese Patent Application Laid-Open No. 11-107243 does not have a configuration for connecting each revetment block with another revetment block, and it is possible to grow a plant by forming a cavity in the revetment block. It is a form that has a configuration. This structure has great disadvantages in terms of effort and cost because each revetment block is not connected to each other, so the gap between each revetment block is inevitably opened due to the flow velocity of the river, back ground pressure or ground subsidence. In addition, since the concrete structure after construction is in direct contact with the surrounding natural environment, there was a problem that adversely affects the surrounding ecosystem.

On the other hand, Japanese Laid-Open Patent Publication No. 2003-090022 and Korean Laid-open Patent Publication No. 2003-0044558 disclose a lanyard block configured to connect each lanyard block to compensate for the above disadvantages, In order to connect the blocks with other revetment blocks, it is cumbersome to use a separate connecting member. As described above, after construction, the concrete structure is exposed to the surrounding environment as it is, disturbing the surrounding ecosystem, There was a problem incompatibility with the natural landscape.

As described above, the conventional rafting block does not have a meshing structure on the block itself, and thus has a problem that is vulnerable to displacement such as uneven settlement of the foundation ground after construction, and connects each raft block using a separate fastening means. In the case of making it, additional costs are required as well as disadvantages in terms of construction period and ease of construction.

In addition, as a measure considering the environmental aspects, the conventional shore banks are merely forming vegetation grooves in the shore banks to enable the growth of plants, and lacking in terms of compatibility with the surrounding ecosystem and the surrounding natural landscape. Many.

An object of the present invention is to solve the above problems of the prior art, having the ability to cope with the unequal settlement of the foundation ground after the construction of the raft block, and to promote the growth of plants and at the same time to stably fix the raft block on the ground It is possible to provide environmentally friendly prefabricated revetment blocks that can be integrated with surrounding ecosystems and surrounding natural landscapes after construction.

According to the present invention, a rectangular block body, three upper projections formed at regular intervals on the upper rear surface of the rectangular block body, two formed at regular intervals on the lower rear surface of the rectangular block body There is provided an eco-friendly prefabricated revetment block with a straw straw layer comprising a straw layer attached to completely cover the lower protrusion and the front surface of the rectangular block body. A plurality of openings for plant growth are formed at the central portion of the rectangular block body and the rice straw layer. Left and right binding grooves are formed on either one of the right side and the left side of the rectangular block body, and left and right engagement protrusions are formed on the other side of the right and left sides. The three upper protrusions are formed at regular intervals from the left end to the right end of the rectangular block body, the left upper protrusion and the right upper protrusion are equal in length, and the length of the center upper protrusion is the left upper protrusion or the right side. Twice the length of the upper protrusion. The lower left protrusion on the left side of the two lower protrusions is formed inward from the left end of the rectangular block body by the length of the left upper protrusion, and the lower right side on the right side of the two lower protrusions. The protrusions are formed inward from the right end of the rectangular block body by the length of the upper right protrusion, and the lower left protrusion and the lower right protrusion are the same length and are spaced apart by the length of the central upper protrusion. have.

According to this configuration, since each of the banks of the banks can be constructed so as to interlock side by side in the lateral direction and the upper banks of the banks of the lower banks and the banks of the upper banks interlocked with each other, the structural integrity of the entire construction structure can be enhanced. Can be.

In other words, the revetment block of the present invention has its own engagement structure with neighboring blocks in the lateral direction and the up and down direction, so that the lower block and the upper block can be alternately constructed when the blocks are stacked. As a result, the structural integrity of the entire construction structure is enhanced.

In addition, the plurality of plant growth openings formed in the block body not only provide a space in which the surrounding plants can grow, but also serve to stably fix the revetment block of the present invention to the ground as a result of plant growth. Do this.

In addition, the conventional revetment block is exposed to the concrete as the main material of the block after construction as it has an environmentally and aesthetically negative result. On the other hand, in the revetment block of the present invention, since a straw straw layer having a certain thickness is attached to the front of the block body, it is difficult to distinguish whether an artificial structure is constructed or a natural state structure after construction, so that the surrounding ecosystem and surroundings It can be blended well with the natural landscape.

In addition, it is preferable that the upper and lower binding recesses are formed on the upper surface of the block body, and the upper and lower binding protrusions are formed on the lower surface of the block body.

According to this configuration, even if the state of the construction ground is uneven, the front surface of the construction can always be aligned, the structural integrity of the entire construction structure can be further enhanced.

The thickness of the rice straw layer is preferably 10mm to 20mm. The reason is that if the thickness of the rice straw layer is too thick (i.e., exceeding 20 mm), the steel straw embedded in the concrete block may come into contact with the rice straw layer, in which case the construction of the rice straw layer may rot after construction, causing the rice straw layer to break from the block. When this is removed, the rebar is exposed to the outside and corroded by rain or river water, resulting in shortening of the lifespan of the raft block, and if the thickness of the straw layer is too thin (ie less than 10 mm), rice straw as described below Not only are the intentions of attaching the layers half-hearted, but the blocks with too thin rice straw layers are difficult to manufacture.

According to the configuration as described above, by using the interlocking structure formed on the block itself without using a separate connecting member during the construction of the foundation ground after the construction of the revetment block simply by assembling each revetment block in the lateral and vertical direction It can have a countermeasure against an unequal settlement of and prevent the phenomenon that some blocks are pushed forward by the back earth pressure. In addition, by simply assembling each of the revetment blocks in the lateral and vertical directions by using the engagement structure formed on the block itself, the construction line can be aligned, and additional construction, such as connection between blocks using fastening means, is unnecessary. This is very simple

And, having a plurality of plant growth grooves, as well as promoting the growth of plants, it is possible to stably fix the constructed revetment block on the ground.

In addition, since the straw layer is attached to the front of the block, not only is well harmonized with the surrounding ecosystem after construction, there is an advantage that the concrete is not directly exposed and compatible with the surrounding natural landscape.

In the following, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

First, in the present specification, "right" and "left" are defined based on the observer when facing the front of the prefabricated revetment block of the present invention.

1 and 2, the revetment block according to the present invention has a rectangular block body 10 and a left end, a center and a right end at regular intervals on the upper rear surface of the rectangular block body 10. Three upper protrusions 20L, 20C, and 20R formed at each of the two, two lower protrusions 30L and 30R formed at regular intervals on a lower rear surface of the rectangular block body 10, and the rectangular block body. And a straw layer 40 attached to completely cover the front surface of 10.

In consideration of the environment-friendly aspect in the conventional revetment block, all that was needed was to make a groove on the concrete surface and fill the soil to grow plants. However, it was difficult for plants to take root on concrete surfaces, and even when rooted, it was difficult to withstand the flow rate during flooding. With this problem in mind, in the present invention, a straw layer 40 is attached to the front surface of the concrete block body 10 to reinforce the environment-friendly surface.

When actually manufacturing the shelter block of the present invention, using a straw straw commonly available in rural areas to form a loose dense stone form before laying concrete on the bottom of the mold, the spacer is placed between the straw straw and the reinforcing bars to space the rebar Then put concrete into it. At this time, the concrete is input while giving a vibration using a vibrator (vibrator) or the like so that the concrete is uniformly injected. After curing the concrete, the mold is peeled off to create an eco-friendly revetment block with a straw straw stick on the surface of the concrete.

Rice straw studs provide a habitat for various aquatic plants to grow, and they are decaying over time and serve as compost for plant growth. In addition, since burning the straw layer is formed irregular grooves that can take root of the plant on the concrete surface, it was also confirmed that the vegetation planted in the opening 15 for plant growth can be easily rooted on the concrete surface. In addition, if the straw-blocked block is installed on the slope of the river or cut section or fill section, the concrete is not exposed to the outside and can be well harmonized with the surrounding natural landscape immediately after construction.

Typically, concrete structures have reinforcing bars inside to support external forces or self-weight, especially where they are in contact with water and should be at least 2 inches (about 51 mm) away from the concrete surface. In view of this point, the thickness of the rice straw layer is preferably 10 mm to 20 mm.

On the other hand, in the central portion of the rectangular block body 10 and the straw layer 40, a plurality of rectangular openings 15 for plant growth are formed. The plurality of plant growth openings 15 not only provide a space for the surrounding plants to grow, but also serve to stably fix the revetment blocks constructed as a result of plant growth to the ground.

In actual construction, when filling the soil (or soil) in the opening 15 for plant growth, if the soil is also sprayed on the surface of the straw layer 40, the soil is filled between the straw can help the plant grow.

As shown in Fig. 1, a groove 11 for left and right binding is formed on either one of the right side and the left side of the rectangular block body 10 (the right side in the drawing). The left and right binding protrusions 12 are formed on the other side (left side in the drawing). At the construction site, when connecting a plurality of raft blocks in the lateral direction, while fitting the construction line by fitting the lateral grooves 11 of one raft block and the left and right projection 12 of the neighboring raft block together. The structural integrity of the construction structure can be strengthened (see FIG. 5).

Meanwhile, as shown in FIGS. 3 and 4, the three upper protrusions are formed at regular intervals from the left end to the right end of the rectangular block body 10, and the upper left protrusion 20L The right upper protrusion 20R is L / 2 in length, and the center upper protrusion 20C is L in length. That is, the length of the center upper protrusion 20C is twice the length of the left upper protrusion 20L or the right upper protrusion 20R. The left lower protrusion 30L on the left side of the two lower protrusions is formed inside at an interval of L / 2 which is the length of the left upper protrusion 20L from the left end of the rectangular block body 10. The right lower protrusion 30R on the right side of the two lower protrusions is spaced inward from the right end of the rectangular block body 10 by L / 2, which is the length of the right upper protrusion 20R. Formed. The lower left projection 30L and the lower right projection 30R have the same length and are spaced apart by L, which is the length of the center upper projection 20C.

According to this configuration, as shown in Figure 7, when stacking a plurality of revetment blocks in two layers, by fitting the lower revetment block and the upper revetment block alternately to each other to strengthen the structural integrity of the entire construction structure. Can be.

8, the upper and lower binding recesses 50 are formed on the upper surface of the block main body 10, and the upper and lower binding protrusions 51 are formed on the lower surface of the block main body 10. By using the up and down binding recesses 50 and the up and down binding protrusions 51, even if the construction ground is uneven, the front surface of the construction structure can always be aligned (in other words, some blocks by the back earth pressure). This can be prevented from being pushed forward or the uneven sinking of the construction ground to turn off some blocks into the ground), the structural integrity of the entire construction structure can be further strengthened.
