Abstract

PURPOSE:To obtain a tough structure without the use of reinforcing bars by a method in which a plurality of metal nets re erected in parallel on a slope by butting their projected portions to form small spaces, and soil is packed into the spaces. CONSTITUTION:A plurality of metal nets 1 are erected in parallel on a slope by butting their projected faces, and the adjacent metal nets 1 are integrally combined by connecting wires 2, where small spaces 3 are formed between the recessed faces of the adjacent nets 1. The metal nets 1 so integrated are driven into the sloped ground or fixed to anchors buried, and soil is packed into the small spaces 3 between the nets 1. The sloped ground can thus be simply stabilized without causing any trouble in placing concrete, and plant seeds can be sowed on the soil for vegetating work.

Description

[Detailed description of the invention] Industrial applications This invention relates to a slope stabilization method.

Conventional techniques As a slope stabilization method, weir plates made of wire mesh or plywood are erected parallel to the slope, concrete is poured between the weir plates to build a structure, and the weight of the structure and the structure are fixed to the slope. The reaction force of the anchor prevents the slope from collapsing.

In this construction method, since the concrete poured between the weir plates flows down the slope, it is necessary to spray concrete with a viscosity higher than a certain level.

Problems to be Solved by the Invention This construction method has the following problems.

■ In order to prevent the concrete from flowing and if the weir plate is made of wire mesh, concrete with a viscosity above a certain level is sprayed and placed, so compressed air is used for spraying, so the end of the hose There is a problem with work safety due to large swings.

■ Spraying creates unevenness on the surface, which is not aesthetically pleasing.

○ Construction is complicated as it is necessary to place reinforcing bars between the weir plates.

Means for Solving the Problems The slope stabilization method according to the present invention consists of a plurality of pieces of wire mesh that have been continuously deformed into corrugated shapes and are stood parallel to each other on the slope by abutting their convex surfaces against each other. A small filling space is formed between each concave surface, and the small filling space is filled with soil.

Since mortar or concrete is not poured, there are no problems associated with concrete pouring in conventional methods of constructing concrete beams.

By sowing seeds on top of the soil, greening becomes possible.

Multiple layers of wire mesh create a strong structure without using reinforcing bars.

Another slope stabilization method according to the present invention is to place mortar or concrete in the small filled spaces between the wire meshes in the above invention.

Since mortar or concrete is placed in a small filled space, the weight of the mortar etc. is not significantly applied to the wire mesh, and even mortar of normal viscosity will not flow out or flow out from the mesh.

Therefore, it is not necessary to spray mortar or the like, and the spraying does not cause any problems with the construction method.

Wire mesh can replace reinforcing bars and create strong concrete beams without using reinforcing bars. Therefore, construction becomes easy.

EXAMPLE Hereinafter, the present invention will be explained in detail based on an example shown in the drawings.

In the figure, reference numeral 1 denotes a wire mesh, which is continuously deformed into a corrugated pattern as shown in FIG. In the embodiment shown in FIG. 1, the wire mesh 1 is bent so as to have a trapezoidal cross section.

As the wire mesh 1, metal lath, expanded metal, punched metal, etc. can be used.

A plurality of wire meshes having the above configuration are stood up in parallel on a slope with their convex surfaces facing each other & adjacent wire meshes 1, 1
are integrated by binding with a binding wire 2.

Other methods include fixing by welding or connecting with bolts and nuts. A small filling space 3 is formed between each concave surface of the adjacent wire meshes 1,1.

A plurality of wire meshes integrated as described above are fixed to anchors that are driven into a slope or buried. As the anchor, a known anchor such as a rock bolt can be used.

A plurality of integrated wire meshes 1 may be arranged in a grid pattern vertically and horizontally as shown in FIG. 4, or may be installed parallel to one direction on a slope.

Add soil to the small filling space B between wire meshes 1 and 1. Seeds can be sown on this soil for greening.

Since mortar etc. are not poured, problems such as spillage do not occur with the conventional method of pouring mortar etc.

Multiple layers of wire mesh create a strong structure without using reinforcing bars.

In another slope stabilization method, mortar or concrete 4 is poured into small filling spaces 3 of a plurality of wire meshes 1 installed on the slope. Since the mortar or concrete 4 is filled in the small filling space 3, its own weight is not applied to the wire mesh 1, so that it does not flow downward or flow out from the mesh. Therefore, it is sufficient to keep the viscosity of the mortar to a normal level, and concrete spraying does not pose any problems with the construction method. Furthermore, the wire mesh 1 can replace the need for reinforcing bars, resulting in a strong concrete structure.

Various embodiments can be considered as the slope stabilization method according to the present invention, and a wire mesh bent and deformed to have a chevron-shaped cross section as shown in FIG. A wire mesh that has been bent and deformed may also be used.

Further, the two inventions of this application may be used together to separate the part where soil is removed and the part where mortar etc. are placed.

Effects of the Invention The slope stabilization method according to the present invention involves standing up a plurality of wire meshes that have been continuously deformed into corrugated shapes in parallel, and filling a small filling space between adjacent wire meshes with soil. Since mortar and the like are not poured, there are no problems with concrete pouring in the conventional method of constructing concrete IJ-t beams, and the construction is also simple.

By sowing seeds on top of the soil, greening becomes possible.

Multiple layers of wire mesh create a strong structure without using reinforcing bars.

The other slope stabilization method according to the present invention is to place mortar or concrete in the small filling space between the wire meshes in the above invention, and the weight of the mortar etc. is not applied to the wire meshes to a large extent, and it has a normal viscosity. Even mortar etc. will not flow out or flow out from the mesh. Therefore, there is no need to spray mortar or the like, and there are no problems with work safety or the appearance of the structure.

Wire mesh can replace reinforcing bars and create strong concrete beams without using reinforcing bars. Therefore, construction becomes easy.
