In the second embodiment, based on the first embodiment, in order to better improve the waterproof capability and prolong the waterproof life of the sponge city waterproof board, the following improvement is made with respect to the connection manner between the waterproof layers 3 in the two adjacent sponge city waterproof boards.
Specifically, the edge of the waterproof layer 3 is further provided with an extending turnover part 31, and the extending turnover part 31 is arranged on the outer side of the middle plate 2 and is abutted against the side wall of the middle plate 2; the extending turnover 31 is configured such that two extending turnover 31 disposed opposite to each other after the two sponge city waterproof boards are spliced together are connected together and form an overlapping portion 300.

Referring to fig. 2, during construction, the edges of two adjacent sponge city waterproof sheets are butted together, so that two oppositely arranged extending turnover parts 31 can be abutted against each other to form an overlapping part 300, and the overlapping part 300 is in an upright state as a whole.
In the later use process, the overlapping part 300 is in a standing state relative to the waterproof layer formed between the waterproof layer 3 and the building, and the connecting area formed by the two extending turnover parts 31 in the overlapping part 300 is arranged in a vertical plane, so that the waterproof and infiltration functions are better. More importantly, in the case that the waterproof layer 3 is shrunk due to the decrease of the external temperature in the later long-term use process, since the two extending turnover parts 31 in the overlapped part 300 are arranged in a vertical plane relative to the main body of the waterproof layer 3, when the tensile force generated by the shrinkage of the waterproof layer 3 reaches a certain value, the root of the overlapped part 300 will crack by a certain amount, and further, the extending turnover part 31 which cracks at the root of the overlapped part 300 is further utilized to generate a proper amount of deformation so as to meet the deformation amount required by the shrinkage of the whole waterproof layer 3 (refer to the separation of the two extending turnover parts 31 in the root area of the overlapped part 300 in fig. 5). Therefore, the problem that the lap joint part is broken easily caused by direct lap joint of the waterproof coiled material along the surface needing waterproof treatment in the prior art can be solved, and the waterproof service life and the use reliability of the sponge city waterproof plate are effectively prolonged.
Wherein, for convenience of processing and manufacturing, the overlapping portion 300 is perpendicular to the waterproof surface formed by the waterproof layer 3.

For example, the connection portion 21 is a plugging protrusion, and the connection mating portion 22 is a plugging groove; alternatively, the connection portion 21 is a lap joint portion, and the connection mating portion 22 is a lap joint mating portion.
Still further, in order to better enhance the waterproof performance of the overlapping portion 300 formed by the extending turnover portion 31, the extending turnover portion 31 completely or partially covers the connection portion 21 and the connection mating portion 22.
Specifically, after two sponge city waterproof boards are spliced together through the connecting portion 21 and the connecting matching portion 22, on one hand, two extending turnover portions 31 which are oppositely arranged are mutually attached and connected to form the overlapping portion, and on the other hand, the overlapping portion is extruded between the connecting portion 21 and the connecting matching portion 22, so that mechanical connection of the two extending turnover portions 31 through the connecting portion 21 and the connecting matching portion 22 is achieved, and connection tightness of the two extending turnover portions is further improved.
Correspondingly, the overlapping portion 300 further forms a bending structure (not shown) between the connecting portion 21 and the connection mating portion 22, and the bending structure can further improve the waterproof capability of the overlapping portion 300.
Through set up water permeable plate and waterproof layer respectively in the both sides of intermediate lamella, water permeable plate can play the effect of reinforcing structural strength as the inoxidizing coating in the outmost, and to the waterproof layer, it can play waterproof effect to the surface of building, and the waterproof layer is in the extension folded part that the outside of intermediate lamella formed, when actually constructing, two panel splice together after, the extension folded part of opposite arrangement can seal and paste together in order to form the overlap, utilize the overlap to seal the gap that forms between two panels, and in later use, when leading to the waterproof layer shrink because external temperature reduces, because the lateral part of overlap whole arrangement at the intermediate lamella, the pulling force that the waterproof layer shrink produced can be transmitted the overlap, in order to utilize the root of overlap to take place the separation and produce appropriate deformation and satisfy the required deformation volume of waterproof layer shrink, waterproof coiled material overlap joint in the prior art causes the fracture and leads to the fact the waterproof layer to break in overlap junction, realize the waterproof life of sponge city waterproof panel and improve reliability.

Therefore, in the actual construction process, the sponge urban waterproof board is paved, so that the waterproof requirement on the surface to be protected is met, and the site construction process can be simplified, so that the construction efficiency is improved.
Compared with the prior art, the sponge urban waterproof board can be directly paved on the upper part of the primary waterproof covering layer after the primary waterproof treatment is finished on the surface to be protected of the building to form the primary waterproof covering layer, so that the concrete is not required to be poured for protection, and the time for waiting for the solidification of the concrete due to the concrete pouring is further saved. After the sponge city waterproof board is paved on the primary waterproof coating layer, backfilling operation can be directly carried out, and the construction period is effectively shortened.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present invention should be included in the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
