Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer for a slope-covering mesh body and a slope surface for suspending a mesh-like body covering and stretching the slope surface at a constant distance from the slope surface in slope protection work. The present invention relates to a mortar / concrete sprayed for protection or a spacer for a slope covering net having a measuring function for measuring the sprayed thickness of a greening material material.

[0002]

2. Description of the Related Art Conventionally, a reticulated body is stretched on a slope, (a)
Concrete or mortar is sprayed on the entire surface of the mesh body, and (b) greening soil material is sprayed on the entire surface of the mesh body.

In the above (a), if the mesh body covering the slope is stretched in a state of floating from the slope, the mesh serves as a reinforcing material for concrete or mortar, and The mortar is less likely to crack. On the contrary, when the mesh body is in contact with the slope, the concrete or mortar only rests on the mesh body, and the mesh body does not serve as a reinforcing bar for the concrete or mortar and cracks in the concrete or mortar. Becomes easier to enter.

In the above (b), when the reticulated body covering the slope is stretched in a state of being floated from the slope, it serves as a locking member for the greening soil material, and the greening soil material is used. Is difficult to peel off from the slope. On the contrary, when the mesh body is in contact with the slope, the greening soil material only rests on the mesh body,
The reticulate body does not serve as a locking material for the vegetative soil material, and the vegetative soil material is easily peeled off from the slope.

Therefore, the spacer pin P shown in FIG. 5 has been devised for the purpose of floating the net-like body from the slope, and has been adopted in many fields. This spacer pin P
Is a thin rod provided with a constricted portion 21 in the middle thereof. By loosening the bent portion of the wire rod 3 forming the mesh body, a hole through which the thin rod can pass is formed. The spacer pin P is inserted into the above, and the bent portion of the wire 3 is fitted into the constricted portion 21 to float the net-like body from the slope.

However, the spacer pin P has the following drawbacks. (A) Since the spacer pin P is rod-shaped and the lower end portion is not stable, the spacer pin P tends to tilt. (B) The spacer pin P loosens the engaging portion of the bent portion of the wire rod 3 forming the mesh body to form a hole through which a thin rod can be inserted, and is inserted into this hole from below the mesh body to form the constricted portion 2
This work is inefficient in a dangerous place such as a high slope because the wire 1 is fitted into the bent portion of the wire 3.
