Description of the Related Art A staircase wire mesh vegetation method is known as a method of greening a concrete slope by spraying concrete onto a steep slope to reinforce the concrete slope. In this method, a stairway wire mesh formed by combining thin metal rods in a vertical and horizontal lattice and bending it in a stepwise manner is prepared, and an earth retaining material such as an earth retaining sheet is attached inside the stairway mesh in advance to form a stair unit. This is fixed to a slope by an anchor or the like, and a vegetation base material or a soil is provided to plant or sow a herb or tree.

所による「フリーフレーム工法（商標）」がある。[0003] In a method in which a stair wire mesh is not provided, a steel bar form reinforced with a reinforcing bar is arranged in a grid pattern (a square pattern) on a steep slope, and concrete is sprayed. There is also known a method of arranging vegetation base material or soil in a basin for vegetation. For example, there is a "free frame construction method (trademark)" by Construction Basic Engineering Co., Ltd. and Ise Anme Net Manufacturing Co., Ltd.

The patent application dated October 28) has found that there are the following problems when incorporating a reinforcing structure. That is, in the conventional vegetation method using a stairway wire mesh, a soil retaining material formed of an earth retaining sheet or the like is arranged on the back side of the stair wire mesh in order to arrange the vegetation base material or the soil. It has been found that the material has an adverse effect such as accumulating rebound of the spraying of the concrete for constructing the reinforcing structure.

限定されるものではない。This will be described in more detail with reference to FIGS. First, as shown in FIG. 3, the staircase wire mesh 10 is arranged on the slope. The arrangement of the staircase wire mesh 10 shows a mode in which the reinforcing structure is constructed in a lattice or square shape, and the staircase wire mesh 10 is arranged in a state where the vertical space 21 and the horizontal space 22 are left for the frame member 20. It is an aspect. Staircase wire mesh 10

結束することが好ましい。According to the construction method according to the present invention described above, the staircase wire mesh 10 is attached to the slope in advance, so that even if the comb wire mesh as the frame member 20 is inserted, it can be firmly fixed. There was a gap between the comb-shaped wire mesh and the slope in places where the irregularities were large, but since it was comb-shaped and there were few horizontal wires, it was easily deformed when pushed in from above and the gap between the ground and the ground Could be eliminated. In such a case, in order to prevent the deformation of the vertical wire material of the comb-shaped wire mesh from returning to the original shape, it is preferable to bind the wire to the staircase wire mesh with a binding wire or the like.

係る不都合が生じた。In the above-mentioned conventional construction method, when the concrete for the reinforcement structure is sprayed, the earth retaining material 30 is previously arranged on the back side of the staircase wire mesh 10, so that the concrete is sprayed on the frame member 20. In this case, the rebound concrete often remains on the back side of the retaining sheet 30, and there is a problem that the cleaning by manual operation is troublesome.

Is generally carried out in the field work in parallel with the fixing of the staircase wire mesh 10 to the concrete slope, so that the above-mentioned inconvenience occurs. At the same time as the production of the step wire mesh 10, a method of incorporating the earth retaining material 30 into the step wire mesh 10 in a factory in advance is also performed. However, when such a step wire mesh 10 is used, only the rebound concrete remains. In addition, various miscellaneous materials entered during the work, and cleaning was often troublesome.

As shown in FIG. 1-A, the earth retaining material 30 is composed of an earth retaining sheet 31 and a heat insulating material 32. A core 34 formed of a metal rod having a diameter of about 3.5 mm is attached to the bent portion 33 of the retaining sheet 31. At the same time, the length of the retaining sheet 31 (step wire mesh 10) is attached to the core 34. Corresponding to the height, in the illustrated one, about 400 m

The core material 34 is wound around the core material, and after the concrete for the reinforcing structure is sprayed, the concrete material is solidified. By rotatably attaching the end to the end of the staircase wire mesh 10, it can hang down as shown in FIG. 1-A. Preferably, the end core material 36 is also arranged at the lower end, and then fixed to the staircase wire mesh 10.

In contrast to the use of the soil retaining sheet 31, since the purpose is to dispose mud having a high water content (for example, 30% of bark compost is mixed with muddy water) as guest soil. Provide a difference in material, etc. That is,
For example, a water-permeable nonwoven fabric is used as the retaining sheet 31 so that only the water in the mud is released. It should be noted that an embodiment in which the same material as the material shown in FIG. 1 is used as the retaining sheet 31 and a water-permeable nonwoven fabric is interposed together with the heat insulating material 32 may be used.

In comparison with the conventional construction method in which concrete is sprayed in a state where the earth retaining material is stuck to the stair wire mesh, cleaning and the like are not troublesome. When the amount of concrete rebounding and adhering to the staircase wire mesh is small, leave it without removing it, or leave a part by removing it moderately,
It can be used as a drainage channel.
