防止している。9 and 10 show an inner slope of a conventional industrial waste disposal site. The inner slope of FIG. 9 is formed by a rubber sheet lining method. The slope of the ground 1 formed by excavation rolling is covered with a non-woven fabric 9, and a rubber sheet 8 is installed as a sealing layer on the slope. The upper edge of the rubber sheet 8 and the non-woven fabric 9 is fixed to the ground with concrete 10. The inner slope of FIG. 10 is formed by the rubber asphalt spraying method. The slope of the natural ground 1 is covered with the non-woven fabric 9a, and the rubber asphalt 8a is sprayed as a sealing layer on the non-woven fabric 9a.
Is fixed to the ground by the fixed soil 10a. As described above, in the conventional industrial waste disposal site, the rubber sheet 8 or the rubber asphalt 8a prevents the waste liquid or the like exuding from the waste 11 stored in the disposal site from diffusing into the ground.

スファルト８ａ及び不織布９ａを貫通する場合もある。In the conventional waste disposal site as described above, holes are easily opened in the rubber sheet 8 or the rubber asphalt 8a as the water sealing layer during construction and during use after completion. There is a problem that the repair is practically difficult and is likely to cause social conflict. That is, in the rubber sheet tension structure as shown in FIG. 9, a rubber sheet 8 having a thickness of 1.5 mm and conforming to JIS 6008A is usually used from the viewpoint of workability. Although this JIS standard specifies the strength itself as a rubber sheet, the following problems occur when it is actually used as a water sealing layer at a waste disposal site. That is, when burying the waste in the disposal site after completion, some of the waste has a shape and hardness that easily perforate the rubber sheet 8, and these are thrown in, The rubber sheet 8 may be pressed into the rubber sheet 8 by landfill pressure.
Perforation or tearing occurs in the. Further, damage to the rubber sheet 8 by the rolling compaction machine itself during the waste landfill work is virtually unavoidable. Furthermore, pinholes are unavoidable due to the stagnation of birds and birds such as crows and hawks. These damages on the rubber sheet 8 cause permeation of harmful liquid exuding from the waste into the ground, resulting in environmental pollution. Therefore, it is necessary to constantly detect and repair these damages. However, these damages are virtually impossible to detect and repair because they are covered under the landfill waste. In addition, pinholes caused by stagnation of birds and birds occur irregularly on a daily basis, and the inspection and repair cannot catch up. On the other hand, in the rubber asphalt spraying structure as shown in FIG. 10, the spraying method makes the construction easy, but the rubber asphalt 8a has a lower mechanical strength than the rubber sheet and is more easily damaged. It may penetrate the asphalt 8a and the non-woven fabric 9a.

る。In addition, in order to maximize the waste storage capacity of the disposal site under a given land area, it is necessary to make the slope of the inner slope as large as possible. However, since the sheet-shaped rubber material has poor adhesion to soil, it is necessary to make the slope of the slope gentle and avoid a complicated slope shape. Therefore, there is a problem that the capacity of storing waste is limited.

As disclosed in Japanese Patent Publication No. 60, a net or lattice sheet-shaped product in which polymer molecules are aligned in a certain direction by heat-drawing polyethylene, is light and has excellent chemical resistance, and has a strength level similar to mild steel. However, in the soil, an interlocking effect that soil particles are restrained in the mesh structure and an effect of reinforcing and stabilizing the embankment by the resistance force when the mesh structure is pulled out from the soil are exhibited. Schematic plan views of the structure are shown in FIGS. The black-painted portion is the heat-stretched sheet portion of the polymer molecule. In this embodiment, these geotextiles are used as a reinforcing and stabilizing auxiliary material for maintaining the function of the impermeable soil layer 2. In the stability calculation of the embankment layer using the geotextile, assuming that the adhesive strength (C) of the ordinary soil itself is 0 t / m 2 , the adhesive strength C is considerably high because the geotextile-applied soil of this example is clay-like. Has a value. Therefore, Geotextile 3
Contributes greatly to stable maintenance of the function of the impermeable soil layer 2 due to a synergistic action with the adhesive force of the impermeable soil layer 2.
