Composite waterproof structure and construction method of anti-seismic joints on side wall of basement

Abstract

The invention relates to a combination-type waterproof structure for a seismic joint of a side wall of a basement and a construction method. A waterproof layer, an isolation layer, an additional waterproof layer and a bitumastic oakum layer are arranged on the outer side of the side wall of the basement. The combination-type waterproof structure is characterized in that an outer layer wall is arranged on the outer side of the seismic joint of the side wall of the basement; the outer layer wall is of an outwards-convex shape; a maintenance joint is formed in an outwards-convex part; an inner layer wall is arranged on the inner side of the seismic joint; the inner layer wall is of an inwards-convex shape; a maintenance channel is formed at an inwards-convex part; an inner and outer side double-layer wall structure is formed; a water-collecting well is arranged at the part, near the wall foot of the inner side wall, in the maintenance channel; a water stop valve is embedded at the connection part of the inner layer wall and the side wall of the basement, and a water stop rubber strip which is inflated in water is laid at the connection part of the inner layer wall and the side wall of the basement; an off-wall-type liner wall is arranged on the inner side of the side wall of the basement, and a water drainage ditch is formed in the wall foot of the isolation-type liner wall; and the water drainage end of the liner wall communicates with the water collecting wall through the water drainage ditch, so that the combination-type waterproof structure is formed. The combination-type waterproof structure has the beneficial effects that the waterproof function is good; the anti-leakage effect is good; the structure is reasonable; and the maintenance is convenient.

Description

technical field [0001] The invention relates to a composite waterproof structure and a construction method of an anti-seismic joint on the side wall of a basement, and is particularly suitable for waterproof buildings on the side wall of a large comprehensive basement. The utility model belongs to the technical field of building waterproof structure systems. Background technique [0002] With the acceleration of the urbanization process, the basement of urban construction is getting bigger and deeper, which is the result of the large-scale and high-rise urban buildings and the full use of the basement space. However, the basement is a hidden project. If there is leakage in the future use, the consequences will be unimaginable. Therefore, the waterproofing of the basement is particularly important and prominent. [0003] The waterproofing of the basement is mainly the waterproofing of the side walls of the basement. Due to the need to consider earthquake resistance, it is n...
