  However, the above products and construction methods have the following problems and disadvantages.

Using natural cobblestones and random natural stones of (1), drilling holes in them and using steel as an adhesive or hole anchor, a single steel or chain shackle will be used to build an anchor on the back embankment. In the empty loading of the method, there was no stability at the construction stage, and it took technology and time for construction, and the efficiency did not increase.

(2) The concrete is made of pseudo-stone cobblestone blocks, and hooks are provided on the back and anchors are installed on the back embankment. In addition to requiring technology and improving efficiency, it was dangerous.

Because the product of (3) natural cobblestone, random natural stone or concrete pseudo-stone block attached to a wire mesh with an adhesive and constructed on the slope has no allowance for earth pressure, 1: 1.5 or more) Although it is good for the construction site, it could not be used as a retaining wall product (standing wall) because stability (falling and sliding) could not be secured.

In the method of constructing and building this block by gluing several stones to the self-supporting form of (4) with an adhesive or embedding in concrete and integrating it, small dimensions (size 15-20cm, weight 20-30kg) It is not possible to make more than the limit product, and if the stone is made large, there is no handle because it is heavy and there is a danger of falling, and even if it is constructed with a machine, a work lifting hand is provided considering the center of gravity of the product There was a need, and there were problems that required a lot of time and technology when bonding or embedding to the concrete of the formwork body, and it was difficult to build gaps between products after construction.

  Therefore, in order to solve the problems of the present invention, the inventor of the present application is familiar with the drawbacks and problems of these products and construction from the experience of manufacturing and delivering a wide range of conventional precast products and many construction sites. The invention of this application was completed through various prototype research.

(1) In addition to being a natural stone product or pseudo stone product as an empty fired ecosystem firefly block, it should be a product that does not give a sense of incongruity to the viewer.

(2) Manufacturing mold cost is low and manufacturing is easy.

(3) As an empty product, the construction should be safe and quick.

(4) To ensure stability (falling, sliding, translational movement) against the construction site conditions.

(5) It must be a construction form that facilitates the growth of flowers on the front wall after construction.

  In the present invention, the exposed portion (stacked surface after construction) is a natural stone (natural cobblestone, random natural stone, crushed stone split) or edging (constructing a combined gap after construction) concrete with a pseudo stone pattern having unevenness changes. This block product is made up of a virtual back plate that is made of concrete and is narrowed down to the bottom edge with concrete from the back side, and is a building block of standing revetment (legal standard 1: 0.3 to 1: 0.5 standard) As a means for constructing an appropriate gap in the adjacent or stacked portion after construction, and facilitating the growth of flowers in this gap.

  By setting the “problem to be solved” and “means for solving” of the present invention as described above, the following effects can be obtained.

(1) Conventionally, natural stone has a stacking surface (Tsumazura), and in the case of kneading (filling the gap with concrete and putting concrete on the back), this stacking surface was exposed to the exposed surface. As a firefight construction revetment that takes into account the ecosystem that requires a gap in the adjacent or stacking part for the purpose of stacking, it requires a proper grounding edge (Aiba), so construction has just required technology and time Even after construction, there was a doubt about stability after being exposed to rain.
However, in the product of the present invention, the stacking surface is selected and the virtual back plate is configured as an integral unit, so the construction work can be handled by putting the stacking surface part on the front, so it does not require technology or time, Not only can the work be done safely, but the virtual back side plate is narrowed down to the bottom edge (planar), so it is easy to build a curve.

(2) For natural stones, the most visible surface (tsutsuzura) can be freely selected, a hole is drilled on the back, and the joint rebar is fixedly attached. Only a concrete formwork may be used, and even in the case of a pseudo stone, an integrated extraction formwork without a combined dismantling of a virtual backside plate part on a stacking face part formwork (usually rubber or FRP) may be used, and the cost is low and the work is easy.
In addition, even large stones with good molds, which could not be used for standing seawalls, flipped the part to be a good stacking surface in the sandbox, drilled holes on the back, and fixed joints for joint reinforcement It is possible to construct a coastal revetment that is mixed with a large variety of products as an accent product by placing the concrete in the formwork of the virtual back plate part (extracted formwork narrowed down to the bottom edge) and commercializing it. It is.

(3) The virtual back plate to be integrated has its length (area) and shape in accordance with the size, soil quality, construction height, loading load, earth pressure conditions, etc. Products that have been changed as necessary can be easily manufactured by setting a sampling form that is narrowed down to the bottom edge, and in the factory, multiple natural stones or pseudo stone pattern products are constructed as horizontally long integrated products with a virtual backside plate. It can be manufactured and provided as a product that can improve efficiency.

(4) The configuration of the virtual back plate ensures stability against earth pressure even when empty.

(5) In the gap formed in the adjacent or stacked portion, planting bags or seed sandbags or stones larger than the gap are sandwiched, and cut gravel is buried in the back, in addition to the flowering flower growing from the gap, it will change Combining a wealth of large products as an accent product at the required location gives the viewer a sense of incongruity when the artificially visible stacking lines (parallel lines at the end of the number of stacked stages) that have been a drawback of standing revetments are interrupted There is no effect.

  Best modes and examples for carrying out the present invention will be described below.

(1) In the invention of this application, it is desirable that the cost of the production form of the product is low and that the construction can be performed safely and quickly without requiring any technology.

In the invention of this application, it is desirable that the stacking surface can be freely selected regardless of the shape of the stone.

(3) It is desirable that the invention according to the present application can be easily manufactured as an empty product according to the conditions of the enforcement site, and stability against earth pressure is ensured.

(4) In addition to considering the provision of openings at important points on the wall and providing easy fireflies larvae hatchery or a place where flowering habitats can grow easily, It is desirable not to give the viewer a sense of incongruity.
