[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit for civil engineering structures used for river protection, shore embankment and road slope protection.

[0002]

2. Description of the Related Art A conventional unit for civil engineering construction of this type is constructed by arranging massive stones c in concrete b in a concrete block forming form a, and has at least three stones at the height of the stones. More than two-fifths are buried in concrete to prevent stones from falling out of the hardened concrete block (see FIGS. 6 and 7).

[0003]

However, in the above civil engineering construction unit, at least two-thirds of the height of the stone must be in the hardened concrete block. Because of this, there are few stones coming out of the concrete block surface and the landscape is not very good.

[0004] The present invention has been proposed in view of the problems of the prior art, and an object of the present invention is to provide a unit for civil engineering construction which does not impair the natural scenery.

[0005]

According to the present invention, there is provided a unit for a civil engineering construction in which a plurality of massive stones are held in a hardened state in an exposed state. Stones are mounted on the base body respectively,
The base body is contained and held in a hardened body, and is configured as a civil construction unit.

[0006] A preferred embodiment of the first aspect is described in the second and subsequent aspects.

[0007]

According to the first aspect of the present invention, a plurality of stones are mounted on the base body, and the base body is held in the hardened body. The base body is restricted from falling out of the hardened body without being exposed to the outside, and each stone can be held in the hardened body without burying a considerable portion of each stone in the hardened body. By increasing the exposed state of the stone, it is possible to suppress the hardened body from being exposed to the outside. Because of this,
It is possible to exhibit an empty stacking condition, and it is possible to harmonize the natural scenery without impairing it. Moreover, in this case, since the base body is included in the hardened body, the base body reinforces the bending strength of the hardened body, and the strength of the civil engineering building unit can be improved. Become.

According to the invention of claim 2, since a plurality of stones are adhered to the base body via an adhesive for attachment to the base body, any special mechanical coupling tool is used. It is possible to attach multiple stones to the base body without the need to prepare, so not only can the number of parts be reduced as much as possible, but also the workability of attaching multiple stones to the base body is improved. Can be done.

According to the invention of claim 3, since the base body is a wire mesh or a mesh, not only can a large number of stones be mounted on the wire mesh or the mesh, but also the thickness of the wire mesh or the mesh can be reduced. Utilizing this, the thickness of the cured body containing the wire mesh or mesh can be reduced, and the amount of material used for the cured body can be greatly reduced.

According to the invention of claim 4, since the stone is natural stone, the natural stone can be harmonized with the natural scenery more.

According to the fifth aspect of the present invention, since the hardened body has water permeability, water from the slope can escape through the hardened body, and a stable civil construction can be provided for a long time. Can be maintained. Moreover, water can be supplied to the sediment deposited between the stones on the hardened body from the back of the hardened body through the hardened body, and between each stone, the growth of plants is promoted, and natural vegetation is promoted. Recovery can be achieved.

According to the invention of claim 6, since the peripheral shape of the cured body is formed in a rectangular shape, it is possible to efficiently and easily lay the civil engineering building unit on the slope. That is, by using the civil engineering building unit, it is possible to quickly construct a civil engineering construction such as a seawall.

According to the invention of claim 7, since the hardened body is made of concrete mortar, the function as the hardened body is concretely performed in order to secure the above-mentioned effects of claims 1 to 6. In addition to this, it is possible to secure necessary and sufficient strength as the strength of the civil engineering building unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. A is a unit for civil engineering structures according to the present embodiment, and this unit for civil engineering structures A is a unit in which a plurality of natural stones 1 are mounted on a base body 2 and at least the base body 2 is a cured body. 5 is included.

As each of the natural stones 1, a massive one is used, and such natural stones 1 are entirely laid on the base body 2. The base body 2 includes a reinforcing bar,
Wire mesh or mesh is used. An adhesive 3 is used for attaching each of the natural stones 1 to the base body 2. The adhesive 3 is layered below each natural stone 1, and the adhesive 3 is applied via the adhesive 3. Base body 2 and each natural stone 1
Are integrated.

As the hardened body 5, a concrete mortar block or the like is to be used. In the present embodiment, a water-permeable concrete mortar block (hereinafter referred to by reference numeral 5) is used. The water-permeable concrete mortar block 5 is formed by filling a water-permeable concrete mortar in a rectangular form 4 and hardening the same, and the concrete mortar is obtained by kneading crushed stones 6a, cement and the like with water. Generated.

As shown in FIG. 3, the concrete mortar block 5 includes the integrated body (a plurality of natural stones 1 mounted on the base body 2). It is sufficient that the natural stone 1 is covered with the concrete mortar block 5 to a thickness of about half the average height. Such a production is performed by putting the above-mentioned integrated material into an uncured water-permeable concrete mortar filled in a rectangular mold 4 and removing the mold after the concrete mortar is cured.

As shown in FIGS. 4 and 5, the unit A for civil engineering structure thus constructed is used for construction of river revetments and retaining walls by being laid on a slope. In this case, the concrete mortar block 5 is included in the concrete mortar block 5 to about half the average height of the natural stone, and the natural stone 1 is exposed to the outside as much as possible, and the exposure of the concrete mortar block 5 is suppressed. Means an empty pile of natural stones 1 and the natural feeling is better.

Further, since the concrete mortar block 5 is formed by kneading crushed stones 6a, cement and the like with water to form a large number of continuous voids and has water permeability, the concrete mortar block 5 has a water permeability. In addition to allowing water to escape, water can be supplied from the back of the concrete mortar block 5 in a state where earth and sand remain between adjacent natural stones 1, and plants grow from between the natural stones 1. By doing so, it is possible to construct a river revetment that aims to restore vegetation.
