Anti-drainage combined waterproof system and construction method for ultra-deep basement

Abstract

The invention discloses an ultra-deep basement anti-drainage combined waterproof system and a construction method, including the painting of waterproof materials after the construction of the main structure is completed and the reasonable arrangement of a pebble water filter layer in subsequent construction practices, so as to achieve waterproofing, water collection and drainage. the goal of. Ultra-deep basements generally refer to basements with three or four floors underground and above. Since the building is located in a deeper part of the ground, the water pressure it bears is relatively large, and it is impossible to maintain a perfect water stop effect. Even if it can be controlled within the allowable error range of the specification, there will be more or less water seepage sites. Although it can be treated by plugging and other methods, the seepage will still exist in a small amount within a certain range, which will affect the normal use of the building. And the repair and repair costs are also large. The invention can effectively solve the phenomenon of leakage and water accumulation in ultra-deep basements, and avoid the dampness of the interior environment of the basement and the influence on the use function of the building.

Description

technical field [0001] The invention relates to a basement waterproof system and a construction method, in particular to an ultra-deep basement anti-drainage combined waterproof system and a construction method. Background technique [0002] With the rapid development of urban construction, the density of buildings is increasing. With the continuous increase of building height, the depth of buildings is also gradually increasing. This makes the basement structure be located in a deep part of the ground, and for areas with a shallow groundwater level, such as Shanghai, Jiangsu and other places, the problem of basement water seepage has become increasingly prominent. The waterproofing method of the basement is usually to do waterproofing before the construction of the main structure, and to do waterproofing after the construction of the structure. Unfavorable phenomena, in addition to affecting the function of the building, will also have an extremely adverse impact on the sa...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an ultra-deep basement anti-drainage combined waterproof system and construction method that can effectively solve the problem of water seepage in ultra-deep basements, so as to change the traditional single waterproof construction method mainly focusing on prevention, so as to prevent Combining main and anti-drainage to ensure that the internal environment of the building is dry and free from water seepage and water accumulation
