Description

Technical Field

[0001] The utility model relates to the technical field of building waterproofing, and specifically relates to a seepage-proof and waterproof structure. Background Art

[0002] In building engineering, in order to prevent buildings from leaking due to water and ponding for a long time, waterproof treatment needs to be carried out on buildings. For example, construction processes such as diaphragm walls and underground chambers are constructed in sections. Therefore, preventing seepage and leakage at the joints between the sectional structures is a key issue.

[0003] The construction of existing multi-layer waterproof layer structures at splicing joints, deformation joints, etc. is relatively complex, and multiple steps such as grouting, filling, and pasting waterstop belts need to be carried out in sequence. Not only is the construction period long, but the construction accuracy is also difficult to guarantee, and construction quality problems are likely to occur. When traditional multi-layer waterproof layer structures are subjected to external forces such as structural deformation and temperature changes, problems such as cracking and aging are likely to occur, greatly reducing the durability of the waterproof layer. Moreover, once the existing multi-layer waterproof layer structure is damaged or fails, due to its complex structure and construction method, it is often very difficult to repair, requiring a large amount of manpower, material resources, and time. Therefore, the utility model proposes a seepage-proof and waterproof structure. Summary of the Utility Model

[0029] An inverted arch structural layer 4 is attached to the lower end of the joint 2 of the wall 1 and extends to the bottom of the side wall 3;

[0030] The waterproof additional layer 8 is painted on the outside of the joint 2, and covers the part of the surface where the inverted arch structural layer 4 intersects with the joint 2. The sprayed rapid-set rubber asphalt waterproof coating waterproof layer 6 is sprayed; the sprayed rapid-set rubber asphalt waterproof coating waterproof layer 6 is sprayed on the outside of the waterproof additional layer 8; the sprayed rapid-set rubber asphalt waterproof coating waterproof layer 6 has excellent waterproof performance and rapid curing characteristics, and can form a dense waterproof film in a short time. The HDPE membrane 5 covers the outside of the sprayed rapid-set rubber asphalt waterproof coating waterproof layer 6. The HDPE membrane 5 has excellent waterproof performance and weather resistance, and can resist the erosion of various external forces. It is closely attached to the waterproof layer to form a double waterproof guarantee, and a protective layer 7 is filled outside the HDPE membrane 5.

The hand-brushed rubber asphalt waterproof coating structure layer 801 has excellent flexibility and ductility, can adapt to the small deformation of the joint 2, and fill potential cracks. Among them, the non-woven fabric 802 serves as the middle layer, enhancing the adhesion of the waterproof coating and the stability of the overall structure.
