Abstract

PROBLEM TO BE SOLVED: To protect a slope from the breakdown while aiming at the planting in a surface thereof by densely laying polygonal prism cells of band-like fiber cloth, and arranging a concrete layer as a lower layer in an area formed by each cell in this aggregate structure as a frame, and arranging a soil layer as an upper layer. SOLUTION: Each cell 2 of a polygonal prism cell aggregate structure 1 is densely laid, and a soil layer 4 is arranged as an upper layer of the cells 2 surrounded by a cell wall 3 vertical against a slope ground 8, and a concrete layer 5 is arranged as a lower layer. At this stage, the cell aggregate structure 1 is formed of the band-like fiber cloth, which can be flexibly expanded to a slope and which can be freely folded. In order to prevent the dispersion of the concrete layer 5 divided into each cell 2, the reinforcing material is embedded and penetrated into the concrete layer 5. Furthermore, a separating cloth is arranged in an interface between the soil layer 4 and the concrete layer 5 so as to prevent the contamination of the concrete layer 5 with the soil layer 4. With this structure, working time from placing of concrete to the throwing-in of soil can be shortened at the time of construction.

2. Description of the Related Art Conventionally, slopes of roads and rivers have often been covered with concrete to prevent collapse. Although such a method is effective in protecting slope collapse, plant growth was extremely difficult. Also, embankment slopes suitable for plant growth have the risk of collapse due to wind and rain. Attempts have been made to provide both soil protection and vegetation by providing a soil layer on the concrete layer. However, there was a danger of the interface between the concrete layer and the soil layer slipping off, and no water was supplied from the original ground to the soil layer, which was not a favorable condition for vegetation.

Means for Solving the Problems In order to achieve the above object, in the slope protection body of the present invention, a cell assembly solid body in which cells, which are polygonal columns of a band-like fiber cloth, are arranged without gaps, is used as a frame. The lower layer is provided with a concrete layer and the upper layer is provided with a soil layer inside the area created by the cells.

[0005] The cell assembly solid body is formed of a fiber fabric such as a belt-shaped woven or non-woven fabric, and the individual cells surround and separate the concrete layer and the soil layer. For this reason, the weights of the concrete layer and the soil layer are supported by the cell wall in units of cells, and by fixing the cell aggregate, it is possible to prevent the concrete layer and the soil layer from sliding down along the slope of the slope.

Further, in order to sufficiently withstand the weight of the concrete layer and the soil layer of each cell and the impact load at the time of laying, it is effective to reinforce the cell, particularly in the longitudinal direction of the cell, that is, in the direction parallel to the slope. As the reinforcing material, a high-strength fiber, a net, a lattice, a woven fabric, or the like may be used, and may be combined with a fiber fabric constituting a cell.

[0007] Since the cell aggregate is made of a fiber cloth, the cross section of each cell wall is porous due to the fine structure between the fibers, and moisture easily propagates. For this reason, even if the slope original ground and the soil layer are separated by the concrete layer, moisture passes along the cell wall in contact with both sides. The dimensions and thickness of the cell are determined based on the required water flow between the original ground and the soil layer. That is, in order to increase the amount of water flow, the cell wall amount per unit area of the slope protection body, that is, by shortening the length of the cell side and forming a set of a large number of small cells, or by increasing the thickness of the belt-like body constituting the cell This can be achieved by increasing the amount of fiber.

In the concrete layer of each cell, the concrete casting thickness is determined by the slope angle of the slope to be protected, ground conditions, and the like. Since the concrete layer is divided for each cell, reinforcing steel, steel wire,
It is preferable that the concrete layers are connected to each other vertically or vertically and horizontally by a reinforcing material such as a fiber rope without being dispersed. In order to deploy such a reinforcing material, it is necessary to pre-drill a through hole in the cell wall of the pre-construction cell assembly three-dimensional structure, and to deploy the reinforcing material in this hole at the time of on-site deployment and then to concrete placement Can be.

The soil layer disposed on the surface layer, which is the upper layer of each cell, is divided into cells similarly to the concrete layer, and the cell walls prevent runoff due to rainfall or the like. The thickness of the soil layer is determined by the amount of soil required for vegetation, and thereby the height of the cell aggregate can be determined. It is optional to sow and fertilize each cell as needed.

[0010] In order to prevent the soil from being washed away by rainfall or the like, if the surface is covered with a cloth or a net after the soil layer is prepared, the slope can be used even on a steep slope. As these coverings, those having high durability such as resin-coated fibers, those which are decomposed by bacteria or the like in a short time such as cellulose fibers, or those in which both are used in combination can be used.
