いものであつた。[Conventional technology] Slope protection methods such as mortar spraying, concrete spraying, and thick layer soil spraying have been widely used mainly for reasons of simplicity and economy. , reinforcing materials for slope protection, such as wire mesh or reinforcing bars, are often placed in the core of the sprayed material. Using reinforcing materials in this way
The purpose is to add strength to the sprayed material and prevent it from flowing away, collapsing, and peeling. Furthermore, in order to strengthen these objectives, it has been proposed to weave wire mesh thickly, and this method not only improves strength and prevents peeling, but also increases resistance to the flow of spray material and prevents it from flowing away.
Enhances collapse prevention effect. However, this method is expensive to manufacture, heavy and difficult to transport and work with.

亡の危険が発生している。 In addition, in recent years, the use of spraying mortar over the entire surface of a building has been reduced for aesthetic reasons, and a construction method in which mortar is sprayed on a part of the building and the rest is greened has been increasingly adopted. That is,
There are methods such as constructing a legal frame with mortar and greening the inside of the frame, and forming a circular green area and spraying the rest with mortar. In this case, wire mesh may be laid in the green area to stabilize the soil. In this type of construction method, even if the slope greatly contributes to stabilization, if the slope is steep or there are long slopes where surface water is concentrated or there are springs. There is a danger that the land will be washed away.

する。[Problems to be solved by the invention] Observing the above-mentioned washing away and collapse phenomena of sprayed material and soil, we find that in most cases, the initial washing away occurs in the upper layer from the surface to the wire mesh. , it usually does not occur below that point. Considering the reason for this, the inventor's past experience suggests that it is because the upper surface of the wire mesh becomes a slipping surface, and in particular, the lattice line array formed by the mesh wires of the wire mesh is in series over the entire surface. It became clear. In fact, when we later observed the construction surface where the initial washout occurred, we found that the upper surface of the wire mesh line was exposed through the sprayed material and soil, and was polished by the collapse of the sprayed material and soil. It is clear from the fact that Therefore, in view of the fact that wire mesh often becomes a slippery surface as mentioned above, the present invention reliably prevents the collapse and washing away of blowwood materials and soil (hereinafter collectively referred to as sprayed materials), and also prevents the reinforcement material from slipping. The object of the present invention is to provide a reinforcing material for slope protection work in which the connecting material can also be used to improve the strength of the reinforcing material as a whole.

渡した構成としてある。[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention is constructed by knitting a continuous corrugated wire rod which is bent in a zigzag shape and has a concave portion formed at each bent valley. Straddling between the separated ends of the first net portion and the second net portion,
A coil-shaped connecting material whose thickness is thicker than both of the net portions when laid is strung together so as to become a part of the entire knitted net.

なる。[Function] Since at least the first and second mesh portions of the wire mesh are made of corrugated wire rods, the strands themselves have a thickness, and the frictional force due to the waveform shape of the wire rods can prevent concrete, mortar, or thick layers. The fixation rate of sprayed materials such as soil is increased. Further, by making the wire mesh into a corrugated shape, it becomes easier to construct and maintain the mesh shape of the wire mesh in a three-dimensional manner, and it becomes possible to increase the thickness considerably by using one layer of the wire mesh.

The desired waveform wire can be easily obtained by arranging the drums at different intervals and passing the wire material between these rotating drums. In this way, the corrugated wire itself is easy to manufacture, and as mentioned above, the corrugation itself increases the adhesion of spraying materials such as mortar. Moreover, since not only a waveform but also a recess is formed in the trough of the waveform, the adhesion of the sprayed material is further improved by forming a step between the trough line and the recess. Incidentally, such a net body itself was previously proposed by the present applicants in Utility Model Application No. 59-34881 (Utility Model Publication No. 63-17543).

なり好適である。 On the other hand, by forming mesh parts made of irregularly shaped connecting materials at predetermined intervals on the basic mesh part made of corrugated wire rods, the mesh line array of the mesh is interrupted in the middle, resulting in a collapse force. Since it is interrupted at irregularly shaped mesh parts and is not added to the overall collapse force, collapse is prevented even on somewhat steep slopes, and even if collapse or washing does occur, it will only be a partial collapse. Furthermore, mortar can also be sprayed along the connecting material, which is suitable as a reinforcing material for the legal frame.

なお、連結材3も波形を形成してもよい。 The irregularly shaped mesh portions, that is, the connecting members 3, which are woven at predetermined intervals into the basic mesh portions of the corrugated strands 10, that is, the mesh portions 1 and 2, are coiled in a round, oval, or diamond shape, for example. It is formed by passing through the bent portions 1a and 2a of 1 and 2.
As described later, mortar, concrete, etc. can be sprayed onto this connecting material part in order to construct a legal frame, so the connecting material 3 is usually a corrugated wire 1.
A wire rod with a larger diameter and greater rigidity than zero is used. The material of the connecting member 3 used in the present invention is usually steel wire or iron wire, and plastic, stainless steel wire, copper wire, or brass wire can also be used.
Note that the connecting member 3 may also have a wave shape.

程度が一般的である。 The number of mesh lines in mesh sections 1 and 2 depends on the size of the mesh, but since the distance between the grid points is usually 50 mm, the number of stages is 3 to 20, usually 8 to 20.
12 stages is preferred. Preferably, the connecting material 3 is woven into the net portions 1 and 2 when weaving the net portion 12 at a factory,
It is integrally fixed to the net parts 1 and 2 in advance. The reinforcement material thus formed is stored and transported in a rolled state. The size of one unit of reinforcing material is preferably about 2 m x 5 m, considering transportation on slopes. Net parts 1, 2

The attachment position of the connecting member 3 to the parts 1 and 2 is selected as appropriate in relation to the slope that is the target of construction. Normally, after construction, a plurality of connecting members 3 are installed parallel to the reinforcing material at regular intervals so that a multi-tiered slope can be constructed horizontally along the slope. There are steps.

い。 To carry out the slope protection method using the above reinforcing material, first, the reinforcing material is rolled into a roll and transported to the slope, and then placed on the slope so that the connecting material extends horizontally. Expand (see Figure 4). Next, it is fixed to the ground using anchor pins or the like. If a frame is also required in the vertical direction, for example, a core material 4 similar to the connecting material 3 is arranged in the vertical direction and bound to the reinforcing material using a wire or the like. In this way, the reinforcing materials are successively laid along the ground. Adjacent reinforcing members are connected to each other by, for example, connecting the joints or the ends of the net portions 1 and 2 with wires or the like through a connecting member. Once the reinforcing material has been installed on the ground, concrete, mortar, or a thick layer of soil is sprayed over the reinforcing material. Concrete and mortar may be sprayed only on the locations where the connecting members 4 are provided to construct the slope 5, and the soil 6 may be sprayed between the slopes. Also,
Instead of using concrete and mortar, a thick layer of soil may be sprayed over the entire surface of the reinforcement.

きる。[Effects] As described above, according to the present invention, since the basic mesh part of the wire mesh, that is, the mesh part, is made of corrugated wire material, (1) the mesh wire itself of the mesh becomes thicker;
It is easy to form a three-dimensional network structure, (2) it has good adhesion to mortar, concrete, and soil, and (3) it can more effectively prevent the spraying material and soil from flowing away and collapsing. In other words, the phenomenon can be prevented in both the net portion and the coil portion, and the effects of both can be synergized. In addition, since connecting members having a shape different from that of the net are woven at regular intervals, the collapse force can be weakened, and even if collapse occurs, it can be limited to only a partial area. Moreover, the connecting material can be used as a core material of the legal frame.
