[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray material stabilization method for slope stabilization of slopes such as slopes facing highways and various facilities constructed by the open cut method, or steep slopes that may collapse. Regarding the device.

[0002]

2. Description of the Related Art If the slope is left as it is, the bedrock will collapse and rocks and topsoil will be washed away by running water such as rainwater. Therefore, the slope is stabilized by the slope stabilization method.

In the above slope stabilizing method, a wire mesh is laid on the slope, and then an anchor pin is driven into the slope to stop the wire mesh on the slope.

Next, a formwork on vertical and horizontal lines on the wire mesh (which is publicly known and will not be described) is placed. In this formwork,
Upper main bar, lower main bar and stirrup are arranged.

Therefore, a hardening material (mortar or the like) is sprayed or placed in the mold.

After that, there is a frame construction method in which a spraying material is sprayed so that the metal net is buried in each square-shaped square defined by the formwork.

As the spray material, a base material in which plant seeds, fertilizers, etc. are mixed, a growth base material, or soil is selected and used according to the purpose.

[0008]

According to the slope stabilizing method as described above, since the spray material flows downward due to the slope of the construction surface (slope), there is a problem that a large variation occurs in the layer thickness of the spray material. there were.

Due to the above variations, a problem that a repair work is required again occurs. In addition, there are variations in greening.

[0010] Therefore, the present invention is to stop the flow of the spray material, and to ease the slope of the construction surface so that the plant can grow easily.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 3, in the spray material stabilizing method and apparatus for slope stabilization of the first embodiment of the present invention, the wire mesh 2 is first laid on the slope A requiring construction. The anchor pin 3 is driven into the slope A from the mesh of the wire net 2 and the wire net 2 is pressed and supported.

On the horizontal line of the wire netting 2, however, at least the lower side of the upper and lower edges is fixed to the slope A or the wire netting 2, and the upper and lower intermediate portions are made of the wire netting inclination relaxing material B.
Is placed.

In the illustrated case, the inclination relaxing member B is, for example, a crimp wire mesh cut into predetermined widths and lengths, bent into a V shape or a shape close to a V shape, and the central portion between the upper and lower edges is surface-oriented. (as away to the surface of the metal mesh 2 in use)
The length of the downstream side is the length of the upstream side with the protruding portion as the boundary
The rewritable bent shorter ulcers than is the lower portion of the parallel longitudinal wires is protruded long downward to the lowermost horizontal member, the protruding portion pierced from above in a network of metal mesh 2, inclined to the wire mesh 2 Although the lower edge side of the relaxation member B is locked, the anchor pin may be driven and stopped on the slope A in addition to the locking using the wire or the like.

Of course, the upper part of the inclination easing member B may be fixed to the slope A or the wire net 2 by the above-mentioned means.

The tilt relaxing portions B may be arranged, for example, in a staggered manner (not shown) in addition to the arrangement of the tilt relaxing portions B in the upper and lower sides of the drawing at a predetermined interval.

Then, the spray material C is sprayed so that the wire netting 2 and the inclination relaxing member B are buried.

The spraying material C may be selected and used according to the purpose, such as a base material in which plant seeds for greening and fertilizer which are suitable for the surrounding environment are mixed, a growth base material, and a soil.

By placing a water-soluble bag (not shown) containing fertilizer inside the inclination relaxing member B in advance, the bag can be dissolved by the absorbed water and the fertilizer water can be supplied.

Of course, the spray material C is not limited to the above, and a spray material suitable for the purpose, for example, an aggregate having a particle size necessary for obtaining known water permeability (such as sieve sand, crushed stone, and artificial lightweight coarse aggregate) is used. Self-hardening adhesive (for example, cement paste as a standard, mix an appropriate reinforcing material when more strength is required, and mix a self-hardening adhesive with a mixture that reduces breathing during curing and prevents cracking) There is also a mixture with.

As described above, due to the presence of the inclination moderating member B, the inclination angle of the slope of the spray surface becomes gentle. For this reason,
The downward flow of the spray material C stops.

Of course, the spray material C is caught by the inclination relaxing member B which is stopped against the wire netting 2 so that the flow of the spray material C also stops more effectively.

In the second embodiment of the present invention, the wire mesh 2 is laid on the slope A as shown in FIGS.

The laid wire mesh 2 is fixed to the slope A by an anchor pin 3 with a hook driven into the slope A. Next, the slope form D is mounted on the wire net 2 on the vertical and horizontal lines.

As is well known, the form D is composed of a pair of left and right side plates using a crimp wire mesh and a connecting frame for connecting the both side plates. The connecting frame has the main bar and the lower main bar. And the upper and lower stirrup are arranged.

Then, concrete or mortar as the hardening material E is cast or sprayed in the mold D.

After that, on the wire mesh 2 of the grid F surrounded by the hardening material D, the inclination relaxing member B similar to that of the first embodiment is provided.
After placing it and stopping it on the slope A or the wire netting 2, the spraying material C is sprayed so that the wire netting 2 and the inclination relaxing member B are buried.

Since the construction of the inclination relaxing member B, the stopper for the wire netting 2 and the spray material C are the same as those in the first embodiment, the description thereof will be omitted.

Then, the inclination of the spraying surface in the grid F becomes gentle due to the existence of the inclination relaxing member B, and the downward flow of the spraying material C is effectively stopped.

It should be noted that, as shown in FIGS. 1 to 5, the mesh of the inclination moderating member B is rough from the middle (from the bottom) to above.
From the middle to the lower edge (the part consisting of the bottom) is dense.

Then, it is possible to effectively stop the flow of the spray material C filled in the inclination relaxing member B.

[0036]

EFFECTS OF THE INVENTION Since the method and apparatus for stabilizing a spray material for slope stabilization according to the present invention have the above-described construction method and structure, the spray material to be sprayed onto a wire net or a square mesh by an inclination relaxing member is extremely effective. It can be effectively stopped and stabilized.

Therefore, various inconveniences caused by the flow of the spray material can be eliminated, and the plants are likely to grow as the slope of the construction surface is relaxed.
