Post-cast strip construction and drainage method for base plate of basement

Abstract

The invention discloses a post-cast strip construction and drainage method for a base plate of a basement. The method is characterized by comprising the following steps: a) prefabricating a permeable tube and a cover plate; b) pre-burying the permeable tube and the cover plate; c) draining a post-cast strip; d) constructing post-cast strip concrete; e) preserving the concrete. With the adoption of a scheme that a permeate well is arranged in the post-cast strip of the base plate of the basement, the method disclosed by the invention not only can meet the collection and the discharge of surface water, but also meet the permeation and the discharge of underground water. The construction of the post-cast strip of the base plate and the combination with a pre-cast base plate are facilitated, and the method has the advantages of simplicity in construction and good permeation and discharge effects. Furthermore, the probability of leakage of the post-cast strip of the base plate is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a post-cast belt construction and drainage method for a basement floor. Background technique [0002] In the concrete construction of the basement floor, due to improper methods or unreasonable technology, the phenomenon of basement leakage often occurs. According to relevant statistics, water leakage defects caused by improper handling of post-cast belts and construction joints account for more than 75%. Therefore, the construction quality of the post-cast belt on the basement floor is the key to preventing basement leakage, and an important link before the construction of the post-cast belt is the problem of drainage. Because the post-pouring zone of the bottom slab is basically at the lowest position of the project before pouring, the groundwater pressure is naturally high, and the surface water of the bottom slab gathers in the post-pouring zone. If no e...

Problems solved by technology

Because the post-pouring zone of the bottom slab is basically at the lowest position of the project before pouring, the groundwater pressure is naturally high, and the surface water of the bottom slab gathers in the post-pouring zone. If no effective treatment measures are taken, during the concrete pouring process in the zone, the accumulated water will A large amount of cement slurry in the concrete will be lost, resulting in a decrease in the strength and impermeability of the concrete

The existing technology adopts the drainage method of open-cut brick drainage wells, but the existing problem is that the brick drainage wells can only meet the collection and drainage of surface water, and because the water permeability of the walls of the brick drainage wells is poor, the groundwater cannot be effectively drained. Infiltrated into the drainage well, in addition, the open-cut brick drainage well is not suitable for soil layers with poor soil quality such as sand and silt; the prior art also has a drainage method using the open-cut type cast-in-place concrete drainage well, and the existing problems are, Due to the poor water permeability of the cast-in-place concrete pool wall, groundwater cannot effectively infiltrate into the drainage well
