DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a downflow stopper for stopping a spraying material to be blown down during slope stabilization.

[0002]

2. Description of the Related Art In a non-frame construction method for slope stabilization, for example, a wire which crosses vertically or horizontally or diagonally on a slope such as a slope is laid, and a wire mesh is laid thereon, and the wire mesh is buried. Spraying materials are sprayed according to the purpose, such as mortar and base material.

[0003] As a prior art for stopping the flow of the spray material on the lower side of the wire mesh of such a construction method, Japanese Patent Application Laid-Open No. 63-78923 is known.
And Japanese Unexamined Utility Model Publication No. 6-1441.

[0004] In the former, each anchor blade protrudes downward from a horizontally long blade plate to drive each blade plate against a slope.

[0005] Then, the crossing of the reinforcing bars arranged vertically and horizontally at the upper end of the anchor shaft slightly projecting upward from the upper edge of the slat is received, mortar is poured thereon, and then a wire mesh is laid. A greening base material is sprayed on it.

[0006] According to such a method, the blade plate with the anchor shaft stops the mortar from flowing before the wire mesh is laid, and the blade plate cannot be used after the wire mesh is laid.

In the case of the latter, a wire mesh is laid on a slope, and a stopper pin is driven into the slope to stop the stopper plate on the wire mesh, so that each of the stopper plates is buried. Spray the soil on the wire mesh.

According to such a method, the stopper plate stops the flow of the soil above the wire mesh (front side).
It is impossible to stop the flow of guest soil under (under) the wire mesh.

In any case, before the wire mesh is laid, or after the wire mesh is laid, it is installed above the wire mesh.

[0010] Then, as shown in FIG. 13, a wire mesh 2 is laid on the slope 1 (a number of wire ropes crossing vertically and horizontally or diagonally may be stretched below the wire mesh 2).
When the spraying material 3 according to the purpose is sprayed so that the wire mesh 2 is buried, if the recess 4 exists due to the unevenness of the surface of the slope 1 (due to undulation of the rock, etc.), the spraying material 3 in the recess 4 is The fluid flows downward due to a steeper slope than the slope, and cavitation and the surface of the sprayed material cannot be flattened by the falling.

In the prior art, it was not possible to install a flow stopper from above the wire mesh into the recess after the wire mesh was stretched.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a downflow stopper that can easily install a spray stopper for spraying material in a recess existing on a slope after laying the wire net.

[0013]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a flow-stopping member having a plurality of comb teeth, one or more of which are pierced into a wire mesh of a slope stabilizing work. And a connecting portion for connecting the upper ends of the respective flow-stop members to each other.

[0014] In addition, a configuration may be adopted in which the degree of upward projection is increased so that the connecting portion serves as a stopper for stopping the flow of the spray material on the surface of the wire mesh in the slope stabilization.

Further, a configuration in which an anchor pin driving guide cylinder is provided at a predetermined position of either the connecting portion or the downflow stopper member may be adopted.

Further, a configuration may be adopted in which a hook that engages with a mesh of a wire mesh for slope stabilization is provided at the connecting portion.

[0017]

Embodiments of the present invention will be described with reference to the accompanying drawings.

In the first embodiment of the present invention, as shown in FIGS. 1 and 2, a plurality of run-down stopper members 11 are arranged in a comb-like shape so as to pierce one or a plurality of stitches in a wire mesh of a slope stabilization work. And the connecting portion 12 connecting the upper ends of the respective flow-stop members 11 together form a flow-stopper A for spraying material for slope stabilization.

The above-mentioned flow stop member 11 and connecting portion 12
In the case shown in FIG. 1, a large number of rods such as wires for the downflow stopper 11 are arranged, and the upper end of the rod is overlapped with one horizontal rod for the connecting portion 12, and the overlapping portion is fixed by spot welding. However, as shown in FIG.
In some cases, the downflow stopper members 11 are juxtaposed by being punched out by a press in a comb-tooth shape so that the upper portion becomes the connecting portion 12.

As shown in FIGS. 3 and 4, the downflow stopper A constructed as described above has a wire mesh C on the slope B of the slope stabilizing work.
When laying, in the part of the recess D caused by the unevenness of the rock or the undulation of the slope B, the wire mesh C in tension
The distance between the slope and the slope B becomes extremely large in the portion of the recess D.

Then, the tip of the downflow stopper member 11 faces the bottom of the recess D while piercing the downflow stopper member 11 of the downflow stopper A from above into the mesh of the wire netting C in the recess D portion. At this time, the connecting portion 12 is brought into contact with the wire net C.

Since the distance from the wire netting C to the bottom of the recess D is different, the length of each downflow stopper 11 is adjusted by cutting or bending using a tool according to the distance. Of course, the horizontally long downflow stopper A is used after being cut into a predetermined length.

Thus, a spraying material E such as a mortar or a mixed base material of greening seeds is sprayed on the wire netting C.

At this time, the flow-down (downward flow) of the spray material E that has flowed into the recess D is prevented by the downflow stopper 11, so that the blowing material E is hollowed in the recess D or from the upper portion in the recess D. An unfilled portion that occurs with the downward flow does not occur.

In the second embodiment of the present invention, as shown in FIG. 5, the connecting portion 12 of the first embodiment becomes a stopper 21 for stopping the flow of the spraying material on the wire mesh surface side of the slope stabilizing work. Increase the degree of upward protrusion.

As means for increasing the degree of upward projection, two connecting rods are arranged vertically in the drawing, and the lower connecting rod is superimposed on the upper surface of the wire mesh to form a connecting portion 12 serving as a stopper 21. Although the amount of protrusion is increased, another means that serves as a stopper may be provided.

The flow stopper A is the same as that of the first embodiment, and the description is omitted.

The downflow stopper A constructed as described above is arranged in the same procedure as in the first embodiment, as shown in FIG. At this time, the flow of the spray material E on the front side (upper side) of the wire net C is stopped by the stopper 21.

The flow-stopping member 1 pierced into the wire mesh C
The operation and effect of 1 are the same as those of the first embodiment, and a description thereof will be omitted.

In the third embodiment of the present invention, as shown in FIGS. 7 and 6, the downflow stopper A of the first and second embodiments is provided with a through guide cylinder 31 of an anchor pin.

Although the above-described guide cylinder 31 is fixed to the flow-stop member 11 at a predetermined pitch by welding in the drawing, the guide cylinder 31 may be provided on the connecting portion 12 or the stopper 21.

Then, the downflow stopping member 11 is meshed with the wire mesh C.
After that, the anchor pin 32 inserted through the guide cylinder 31 is driven into the slope, and the downflow stopper A is attached to the slope B.

Then, the downflow stopper A can be stably supported on the slope B.

The operation and effect of the downflow stopper A are similar to those of the first and second embodiments, and the description thereof is omitted.

In the fourth embodiment of the present invention, as shown in FIG. 9, a hook engaging with a mesh of a wire mesh is provided on the upper edge (connection portion) of the downflow stopper A of the first and second embodiments. 41 are provided.

In the illustrated case, the hook 41 is formed by bending the upper end of the downflow stopper member 11 into an L-shape. However, the hook 41 is separately attached to the downflow stopper A by welding or the like. May be provided.

Then, as shown in FIG. 10, the flow-stopping member 11 is pierced into the mesh of the wire mesh C, and the hook 4 is inserted into the mesh.
1 is engaged to set the downflow stopper A, and the downflow stopper A is stably supported by the engagement relationship between the hook 41 and the mesh.

[0038] As shown in FIG.
If the guide pin 31 is provided on the slant face B and the anchor pin 32 inserted into the guide pin 31 is driven into the slope B, the downflow stopper A can be held more stably.

The structure and operation and effect of the hook 41 with the hook 41 are the same as those of the first embodiment, and the description is omitted.

[0040]

The downfall stopper for spraying material of the slope stabilizing work according to the present invention is constructed as described above, so that the spraying material blown into the recess on the lower slope of the wire mesh is stopped from flowing down. Inconveniences such as cavitation and generation of an unfilled portion can be eliminated.

The flow of the spray material on the front side of the wire mesh can be stopped by the stopper.

Further, the downflow stopper can be stably supported by the anchor pin or the hook inserted into and driven into the guide cylinder.
