[0034] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.
[0035] Example 1
[0036] Figures 1 to 10 The first embodiment of the utility model is as follows: Figure 1 As shown, a waterproof drainage board includes a waterproof board 1, a drainage net 2, and a water filter cloth 3. The waterproof board 1, the drainage net 2, and the water filter cloth 3 are sequentially bonded together from bottom to top. Figure 4 As shown, the waterproof board 1 includes an anti-seepage layer 11 and an anti-slip layer 12 . The anti-seepage layer 11 is a complete rectangular plastic board, and the anti-slip layer 12 is arranged on the top surface and the bottom surface of the anti-seepage layer 11 .
[0037] like Figure 3 As shown, the anti-slip layer 12 includes anti-slip strips a121, which are evenly arranged at equal intervals, and the anti-slip strips a121 are inclined relative to the side of the anti-slip layer 12. The anti-slip strips a121 form a 45-degree angle with the side of the anti-slip layer 12. The anti-slip strips a121 are arranged in two groups, and the two groups of anti-slip strips a121 cross each other perpendicularly. The anti-slip layer 12 on the bottom surface of the anti-seepage layer 11 also includes wear-resistant heads 122, and multiple wear-resistant heads 122 are evenly arranged in the gap between the two anti-slip strips a121.
[0038] like Figure 5 As shown, the height of the wear-resistant head 122 is the same as the height of the anti-slip strip a121. Figure 6 As shown, the top of the wear-resistant head 122 is spherical, and the bottom of the wear-resistant head 122 is an arc surface, which is tangent to the bottom surface of the anti-seepage layer 11 and the top sphere of the wear-resistant head 122 respectively.
[0039] like Figure 7The drainage net 2 comprises a water-passing net 21 and a water-guiding net 22. The water-passing net 21 is arranged above the water-guiding net 22. The water-passing net 21 contacts the water-filtering cloth 3. The water-guiding net 22 contacts the waterproof board 1. The water-passing net 21 and the water-guiding net 22 are both composed of a plurality of evenly spaced card strips. The card strips are arranged obliquely. The card strips in the water-passing net 21 and the card strips in the water-guiding net 22 are arranged crosswise. The card strips are arranged at an angle of 45 degrees relative to the side of the drainage net 2. The card strips in the water-passing net 21 and the card strips in the water-guiding net 22 are perpendicular. The card strips in the water-passing net 21 and the card strips in the water-guiding net 22 are bonded together at the intersection. The water flowing down from the waterproof drainage board is filtered by the water-filtering cloth 3 and enters the drainage net 2, and then is discharged from the drain outlet along the drainage net 2. When the water volume is small, the water flows in the water guide net 22; when the water volume is large, the water flows over the water guide net 22 and enters the water passing net 21, and then enters the adjacent water guide net 22 through the water passing net 21 to realize water diversion, thereby reducing local drainage pressure. By arranging the card strips at an angle, the drainage nets on one side and the drainage nets on both sides can be conveniently connected as a whole, thereby sharing the drainage pressure and improving the drainage capacity.
[0040] like Figure 8 , Fig.10 As shown, the water guide net 22 is provided with an anti-slip strip b23 on one side close to the waterproof board 1. The anti-slip strip b23 is provided along the clamping strip and at the center of the clamping strip.
[0041] Example 2
[0042] Fig.11 , Fig.12 This is a usage state diagram of an embodiment of the utility model, such as Fig.11 As shown in the figure, a landfill pit is constructed using the waterproof drainage board. First, a pit is dug at the construction site and the pit wall is compacted and strengthened. Then, waterproof drainage boards are laid on the pit wall. Adjacent waterproof drainage boards are welded and connected to form a closed pit wall. The landfill pit is funnel-shaped, and a drainage port is set at the bottom of the landfill pit. The water in the garbage flows from the drainage port through the waterproof drainage board into the wastewater treatment equipment below.
[0043] A waterproof drainage board is installed at the bottom of the landfill pit to prevent waste water from flowing into the ground, thus preventing groundwater pollution.
[0044] principle:
[0045] By providing an anti-skid layer 12 on the bottom surface of the anti-seepage layer 11, the waterproof drainage board can avoid sliding off the engineering work surface during installation; by providing an anti-skid layer 12 on the top surface of the anti-seepage layer 11, the stability between the waterproof board 1 and the drainage net 2 is improved, the drainage net 2 is prevented from sliding, and the stability of the drainage performance of the waterproof drainage board is ensured.
[0046] The top of the wear-resistant head 122 is set to be spherical, and the bottom of the wear-resistant head 122 is an arc surface, which can enhance the ability of the wear-resistant head 122 to withstand tangential forces and avoid deformation and bending, which affects the gripping ability. The wear-resistant head 122 is made of the same plastic material as the anti-seepage layer 11, and the material of the anti-slip strip a121 is any one of PE, PD, PVC, EVA, and polyester. The wear-resistant head 122 can increase the gripping force, and the anti-slip strip a121 can increase the friction force on the surface of the waterproof board 1. The inclined anti-slip strip a121 and the two groups of crossed anti-slip strips a121 can increase the gripping force of the anti-slip strip a121 and achieve an anti-slip effect.
[0047] By providing the anti-slip strip b23, the stability between the waterproof board 1 and the drainage net 2 is improved, the drainage net 2 is prevented from sliding, and the stability of the drainage performance of the waterproof drainage board is ensured.
[0048] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
