Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterproof engineering materials, in particular to a new type of plastic plate. Background Art
[0002] In order to protect the water resources below, landfills need to be waterproofed to isolate the sewage from above and collect it for harmless treatment. Currently, waterproof drainage projects are mostly completed by laying waterproof drainage boards. The waterproof drainage board consists of three parts from top to bottom: geotextile, drainage net, and waterproof board. The geotextile is used to filter water flow, the drainage net is used to drain water, and the waterproof board is used to isolate water flow.
[0003] Existing waterproof drainage boards are divided into two categories: one is that the drainage net and the waterproof board are formed in one piece, and the drainage net is set on the back of the waterproof board and extruded together, such as the waterproof board with a water filter layer and water guide groove disclosed in the utility model patent application number 200820028590.9; the other is that the drainage net and the waterproof board are produced independently and then assembled into one waterproof drainage board. For waterproof drainage boards where the drainage net and the waterproof board are produced independently, the drainage net can be set as a cross-layer, such as a HDPE filter pad disclosed in the utility model patent application number 201820126924.X.
[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art: 1. Support columns or support bars are evenly arranged on one side of the integrally formed drainage net, and the gaps between the support columns or support bars and the support columns or support bars form a drainage net. If the height of the support columns or support bars is set too high, the pressure-bearing capacity is insufficient, and if it is set too low, the permeability is insufficient, and the drainage and exhaust effects are not good; 2. For the waterproof drainage board in which the drainage net and the waterproof board are independently produced, the drainage net is arranged in a cross-layer manner, which improves the pressure-bearing capacity, but also causes the permeability of the drainage net to decrease, affecting the water permeability and air permeability; 3. For the waterproof drainage board in which the drainage net and the waterproof board are independently produced, the drainage net and the geotextile are easy to fall off, resulting in a shortened project life. Summary of the invention
[0005] In view of the deficiencies of the prior art, the utility model develops a new type of plastic plate, which can ensure the permeability of the drainage net on the basis of ensuring the pressure bearing capacity, and the drainage net and geotextile are not easy to fall off, thereby ensuring the service life of the project.
[0006] The technical solution to the technical problem solved by the utility model is as follows: an embodiment of the utility model provides a new type of plastic board, including a geotextile, a drainage net, and a waterproof board. The geotextile, the drainage net, and the waterproof board are arranged in sequence from top to bottom. The drainage net includes a top layer, a middle layer, and a bottom layer. The top layer, the middle layer, and the bottom layer are an integrally formed structure. The middle layer includes transverse reinforcement strips, and the transverse reinforcement strips are parallel and evenly arranged to each other. The top layer and the bottom layer are respectively arranged above and below the middle layer, and the top layer and the bottom layer are provided with drainage support nets.
[0007] As an optimization, the top layer and the bottom layer include a plurality of evenly arranged longitudinal support bars, which are parallel to each other and evenly arranged, and are perpendicular to the transverse reinforcement bars, and the longitudinal support bars form a drainage support network.
[0008] As an optimization, the cross-sections of the transverse reinforcement strips and the longitudinal support strips are circular or rectangular.
[0009] As an optimization, the top layer and the bottom layer include a plurality of columns, the columns are evenly arranged, one end of the columns is in vertical contact with the transverse reinforcement strip, the columns are parallel to each other and evenly arranged, and the columns form a drainage support network.
[0010] As an optimization, a conical tip is provided on the top of the column in the top layer, and the bottom area of the conical tip is smaller than the cross-sectional area of the column.
[0011] As an optimization, the middle layer also includes longitudinal reinforcement strips, which are parallel to each other and evenly arranged, and are perpendicular to the transverse reinforcement strips, and the longitudinal reinforcement strips and the transverse reinforcement strips are an integrally formed grid structure.
[0012] As an optimization, the middle layer also includes a diagonal reinforcement bar, the two ends of which are respectively connected to the two diagonals of the square, and the diagonal reinforcement bar is an integrally formed structure with the longitudinal reinforcement bar and the transverse reinforcement bar.
[0013] As an optimization, the surface of the waterproof board that contacts the drainage net is the top surface of the waterproof board. A positioning groove is provided on the top surface of the waterproof board. The position of the positioning groove corresponds to the position of the column in the bottom layer. The positioning groove is a raised square ring or circular ring, and the column is inserted into the ring of the positioning groove.
[0014] As an optimization, the bottom surface of the waterproof board is provided with anti-slip strips, the anti-slip strips are evenly arranged at equal intervals, the anti-slip strips are inclined relative to the sides of the waterproof board, and the anti-slip strips are provided in two groups, and the two groups of anti-slip strips cross each other perpendicularly.
[0015] As an optimization, the bottom surface of the waterproof board is further provided with anti-slip heads, and a plurality of anti-slip heads are evenly arranged in the gaps between the anti-slip strips, and the height of the anti-slip heads is the same as that of the anti-slip strips.
[0016] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:
[0017] 1. By setting the drainage net into three layers, the pressure bearing capacity is improved. The new plastic plate can ensure the permeability of the drainage net while ensuring the pressure bearing capacity.
[0018] 2. By setting the top and bottom layers to be composed of columns, the gaps between the columns are larger, which increases the permeability of the drainage support net and makes the discharge of wastewater and exhaust gas more convenient.
[0019] 3. By setting a conical tip on the top of the column in the top layer, when the geotextile is combined with the drainage net, the conical tip can be inserted into the geotextile to prevent it from falling off. The bottom area of the conical tip is set to be smaller than the cross-sectional area of the column, which can limit the geotextile to fall to the bottom of the conical tip at most, avoiding occupying the space of the drainage support net.
[0020] 4. By setting longitudinal reinforcement strips and diagonal reinforcement strips, the strength of the middle layer is improved and the overall compressive resistance of the drainage network is improved.
[0021] 5. By setting the positioning groove and inserting the column into the ring of the positioning groove, the drainage net can be prevented from falling off, thus ensuring the service life of the project. Sewage and waste gas can be discharged through the gaps between the longitudinal support strips. When the drainage support net on the bottom layer is filled, it can also pass through the middle layer into the top layer and be discharged through the drainage support net on the top layer.
[0022] 6. The anti-slip head is integrally formed with the waterproof board. The anti-slip head is made of the same plastic material as the waterproof board, and the anti-slip strip is made of any one of PE, PD, PVC, EVA, and polyester. The anti-slip head can increase the grip, and the anti-slip strip can increase the friction on the surface of the waterproof board. The two sets of crossed inclined anti-slip strips can increase the grip and achieve an anti-slip effect. The top of the anti-slip head is spherical, and the bottom of the anti-slip head is an arc-shaped surface. The arc-shaped surface is tangent to the bottom surface of the waterproof board and the top sphere of the anti-slip head respectively. Setting the top of the anti-slip head to be spherical and the bottom of the anti-slip head to be an arc-shaped surface can enhance the ability of the anti-slip head to withstand tangential forces, avoid deformation and bending, and affect the grip.

[0036] 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.
[0037] Example 1
[0038] Figure 1 , Figure 2 The first embodiment of the utility model is as follows: Figure 1 As shown, a new type of plastic board includes a geotextile 1, a drainage net 2, and a waterproof board 3. The geotextile 1, the drainage net 2, and the waterproof board 3 are arranged in sequence from top to bottom. Figure 2As shown, the drainage net 2 includes a top layer 21, a middle layer 22, and a bottom layer 23. The top layer 21, the middle layer 22, and the bottom layer 23 are an integrally formed structure. The middle layer 22 includes transverse reinforcement bars 221. The transverse reinforcement bars 221 are parallel to each other and are evenly arranged. The top layer 21 and the bottom layer 23 are respectively arranged above and below the middle layer 22. The top layer 21 and the bottom layer 23 are provided with a drainage support net. The top layer 21 and the bottom layer 23 include a plurality of evenly arranged longitudinal support bars 211. The longitudinal support bars 211 are parallel to each other and are evenly arranged. The longitudinal support bars 211 are perpendicular to the transverse reinforcement bars 221, and the longitudinal support bars 211 form a drainage support net. The cross-sections of the transverse reinforcement bars 221 and the longitudinal support bars 211 are rectangular.
[0039] Design principle:
[0040] Sewage and waste gas can be discharged through the gaps between the longitudinal support strips 211. When the drainage support net of the bottom layer 23 is filled, the waste gas can also pass through the middle layer 22 into the top layer 21 and be discharged through the drainage support net of the top layer 21. By setting the drainage net 2 as three layers, the pressure bearing capacity is improved. The new plastic plate can ensure the permeability of the drainage net while ensuring the pressure bearing capacity.
[0041] Example 2
[0042] Figures 2 to 14 This is the second embodiment of the utility model, which differs from the first embodiment in that: Figure 8 As shown, the top layer 21 and the bottom layer 23 include a plurality of columns 231, which are evenly arranged, one end of the column 231 is in vertical contact with the transverse reinforcing strip 221, and the columns 231 are parallel to each other and evenly arranged, and the columns 231 form a drainage support network. The top of the column 231 in the top layer 21 is provided with a conical tip, and the bottom area of the conical tip is smaller than the cross-sectional area of the column 231.
[0043] like Figure 7 As shown, the middle layer 22 also includes longitudinal reinforcing strips 222, which are parallel to each other and evenly arranged, and are perpendicular to the transverse reinforcing strips 221. The longitudinal reinforcing strips 222 and the transverse reinforcing strips 221 are an integrally formed lattice structure. The middle layer 22 also includes diagonal reinforcing strips 223, and the two ends of the diagonal reinforcing strips 223 are respectively connected to the two diagonals of the lattice. The diagonal reinforcing strips 223 are an integrally formed structure with the longitudinal reinforcing strips 222 and the transverse reinforcing strips 221. By providing the longitudinal reinforcing strips 222 and the diagonal reinforcing strips 223, the strength of the middle layer 22 is improved, and the overall compressive resistance of the drainage net 2 is improved.
[0044] like Figures 10 to 14As shown, the surface of the waterproof board 3 in contact with the drainage net 2 is the top surface of the waterproof board 3. A positioning groove 33 is provided on the top surface of the waterproof board 3. The position of the positioning groove 33 corresponds to the position of the column 231 in the bottom layer 23. The positioning groove 33 is a raised square ring or a circular ring. The column 231 is inserted into the ring of the positioning groove 33. The bottom surface of the waterproof board 3 is provided with anti-slip strips 31. The anti-slip strips 31 are evenly arranged at equal intervals. The anti-slip strips 31 are inclined relative to the side of the waterproof board 3. The anti-slip strips 31 are arranged in two groups, and the two groups of anti-slip strips 31 are perpendicular to each other. The bottom surface of the waterproof board 3 is also provided with anti-slip heads 32. A plurality of anti-slip heads 32 are evenly arranged in the gaps between the anti-slip strips 31. The height of the anti-slip heads 32 is the same as the height of the anti-slip strips 31.
[0045] Design principle:
[0046] By setting the top layer 21 and the bottom layer 23 to be composed of columns 231, the gaps between the columns 231 are larger, the permeability of the drainage support net is increased, and the discharge of wastewater and waste gas is more convenient. By setting a conical tip on the top of the column 231 in the top layer 21, when the geotextile 1 is combined with the drainage net 2, the conical tip can be inserted into the geotextile 1 to prevent it from falling off. The bottom surface area of the conical tip is set to be smaller than the cross-sectional area of the column 231, which can limit the geotextile 1 to fall to the bottom of the conical tip at most, avoiding occupying the space of the drainage support net.
[0047] By setting the positioning groove 33, the column 231 is inserted into the ring of the positioning groove 33, which can prevent the drainage net 2 from falling off and ensure the service life of the project. The anti-slip head 32 is integrally formed with the waterproof board 3, and the anti-slip head 32 is made of the same plastic material as the waterproof board 3. The material of the anti-slip strip 31 is any one of PE, PD, PVC, EVA, and polyester.
[0048] The anti-skid head 32 can increase the grip, the anti-skid strip 31 can increase the friction force on the surface of the waterproof board 3, and the two groups of crossed inclined anti-skid strips 31 can increase the grip and achieve an anti-skid effect. The top of the anti-skid head 32 is spherical, and the bottom of the anti-skid head 32 is an arc surface, which is tangent to the bottom surface of the waterproof board 3 and the top sphere of the anti-skid head 32 respectively. The top of the anti-skid head 32 is spherical, and the bottom of the anti-skid head 32 is an arc surface, which can enhance the ability of the anti-skid head 32 to withstand tangential forces, avoid deformation and bending, and affect the grip.
[0049] 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.
