Description

[Brief explanation of the drawing]

Figure 1 shows a three-layer water-permeable sand control mat, Figure 2 shows a hume pipe with small holes for water seepage, Figure 3 shows a U-shaped groove with small holes for water seepage, and Figure 4 shows water seepage. Culvert with small hole, No. 5
The figure shows a roof-shaped U-shaped groove cover with small holes for water infiltration, and the figure 6 shows a U-shaped flat cover with small holes for water infiltration. Figure 8 is a cross-sectional view of the U-shaped groove shown in Figure 3, with the roof-shaped lid shown in Figure 5 placed over it, and the sabo mat shown in Figure 1 covered and buried underground. Figure 9 is a cross-sectional view of the U-shaped trench shown in Figure 3 with the flat cover shown in Figure 6 placed over it, the erosion control mat shown in Figure 1 covered and buried underground, and Figure 10. , Figure 11 is a cross-sectional view of the culvert shown in Figure 4 covered with the erosion control mat shown in Figure 1 and buried underground.
The flat plate shown in Fig. 6 is placed in the U-shaped groove shown in the figure, the erosion control mat shown in Fig. 1 is covered, and the top surface of the mat is the same as the ground surface. Fig. 12 is a cross-sectional view of the culvert shown in Fig. 4. A cross-sectional view of the erosion control mat shown in Figure 1 covered and buried with the top surface of the mat being the same as the ground surface, Figure 13 is a U with small holes for water penetration on one side.
Figure 14 is a cross-sectional view of the flat cover shown in Figure 6 placed in the U-shaped groove shown in Figure 6 and buried underground with an erosion control mat protruding from one side. Figure 15 is a cross-sectional view of the erosion control mat shown in Figure 1 covered on two sides and with one side protruding, and the upper part buried underground in a floating manner. Figure 16 shows a perspective view and a partial exploded view of the humid pipe in Figure 2 covered with the erosion control mat shown in Figure 1 and connected to the top of the water collection tank and buried underground. A perspective view and a partially exploded view of the structure connected to the bottom and buried underground. '1: Small hole layer of water permeable erosion control mat, 2: Medium hole layer of water permeable erosion control mat, 3: Large hole layer of water permeable erosion control mat, 4
: Multi-layer type of water-permeable erosion control mat, 5: Base material of drainage channel component, 6: Small holes for water permeation, 7: Ground surface, 8: Water level, '9 Road surface, 10: Cut-through surface of soil, 11 : Crushed stone for railway road bed, 12: L/-le.
