Abstract
Description
Technical Field
[0001] The utility model relates to the field of anti-drainage boards, in particular to an integrated anti-drainage board for storing and draining water and preventing roots for sponge cities. Background Art
[0002] "Sponge City" is a new concept of urban construction, which means that the city is like a sponge, with good "elasticity" in adapting to environmental changes and responding to natural disasters. It absorbs water, stores water, seeps water, and purifies water when it rains, and "releases" and utilizes the stored water when needed. Planting roofs have life characteristics and their own operating laws. They are an important factor in promoting "urban vitality". In green buildings, roof greening is an important criterion. Planting greening is a direct form of ecological architecture. Planting roofs not only save energy, but also improve the ecological environment. Conventional planted roofs are composed of 8 parts: vegetation layer, planting layer, filtration layer, water storage and drainage layer, moisture retention layer, root barrier layer, anti-seepage layer, and original building top. The structural hierarchy is complex and the construction is difficult. Therefore, the utility model proposes an integrated drainage board for water storage and root barrier for sponge cities. Utility Model Content
[0003] The utility model aims to provide a sponge city water storage and drainage root barrier integrated anti-drainage board to solve the problem.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] The utility model discloses an integrated water storage and root barrier anti-drainage board for sponge cities, comprising a bottom plate, on which a plurality of groups of water storage components are spaced apart, the water storage components comprising a plurality of convex shell water storage grooves that are equally spaced laterally, drainage grooves being arranged between adjacent water storage components, and the depth of the convex shell water storage grooves being greater than the depth of the drainage grooves.
[0006] Furthermore, the drainage groove circumferentially wraps around the convex shell water storage tank.
[0007] Furthermore, the depth of the convex shell water storage tank is not less than 10 mm, and its diameter is not less than 10 mm.
[0008] Furthermore, the depth of the drainage groove is 1.0 mm.
[0009] Furthermore, the bottom plate, the convex shell water storage tank and the drainage tank are an integrally formed structure.
[0010] Furthermore, the top diameter of the convex shell water storage tank is larger than the bottom diameter.
[0011] Furthermore, the bottom of the convex shell water storage tank is smoothly transitioned.
[0012] Compared with the prior art, the beneficial technical effects of the utility model are:
[0013] The utility model discloses a sponge city integrated drainage and root barrier board that reduces the structural layers, so that the drainage layer, the root barrier layer and the anti-seepage layer are combined into one structural layer, so that the drainage board has the functions of water storage, drainage, root barrier and waterproofing, and forms a double-layer waterproof effect with the anti-seepage layer.

[0019] Explanation of the reference numerals: 1. bottom plate; 2. convex shell water storage tank; 3. drainage tank. DETAILED DESCRIPTION
[0020] like Figure 1-4 As shown, a sponge city integrated water storage and root barrier anti-drainage board includes a base plate 1, on which a plurality of groups of water storage components are spaced apart. The water storage components include a plurality of convex shell water storage tanks 2 that are equidistantly distributed laterally, and drainage tanks 3 are arranged between adjacent water storage components. The depth of the convex shell water storage tank 2 is greater than the depth of the drainage tank 3.
[0021] The bottom plate 1 is made of a mixture of high-density polyethylene (HDPE) resin and linear low-density polyethylene (LLDPE) to ensure its waterproof and root-blocking properties.
[0022] The drainage groove 3 surrounds the convex shell water storage tank 2 in an annular direction. Figure 1 It can be seen that the drainage grooves 3 are distributed in a honeycomb shape, and the convex shell water storage tank 2 is located in the center.
[0023] The depth of the convex shell water storage tank 2 is not less than 10 mm, and its diameter is not less than 10 mm.
[0024] The depth of the drainage groove 3 is 1.0 mm.
[0025] The bottom plate 1, the convex shell water storage tank 2 and the drainage tank 3 are an integrally formed structure, and are produced by set double-roller negative pressure adsorption molding. The thickness of the bottom plate 1 is not less than 2.0 mm.
[0026] The top diameter of the convex shell water storage tank 2 is larger than the bottom diameter, presenting an inverted cone structure, which is convenient for water storage.
[0027] The smooth transition treatment of the bottom of the convex shell water storage tank 2 can reduce the resistance of the fluid at the connection part and the generation of turbulence.
[0028] The storage and drainage process of the utility model is as follows:
[0029] Rainwater penetrates into the integrated drainage and root barrier board from the outside. First, part of the rainwater flows along the drainage groove 3, and the other part of the rainwater is stored in the convex shell water storage tank 2. When the water volume is too large, after the convex shell water storage tank 2 is full, the excess rainwater will flow away through the drainage groove 3; at the same time, since the drainage groove 3 circumferentially wraps the convex shell water storage tank 2, it can ensure that the rainwater overflowing from the convex shell water storage tank 2 is discharged in time, avoiding the accumulation of rainwater.
[0030] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
