Basement sump structure

Abstract

The invention relates to a basement sump structure. The basement sump structure is arranged below a bottom plate of a basement and used for temporarily storing sewage water or miscellaneous water. The basement sump structure comprises a sump body fixedly arranged below the bottom plate of the basement. The sump body comprises a bottom plate and sidewalls, wherein the bottom plate and the sidewalls define a catchment cavity. The catchment cavity is a cavity with an opening in the upper portion. The upper edges of the sidewalls are fixedly connected to the bottom plate of the basement. A pit opening communicated with the catchment cavity is formed in the position, located in the opening in the upper portion of the catchment cavity, of the bottom plate of the basement. The area of the pit opening is smaller than that of the opening of the catchment cavity. According to the basement sump structure, the pit opening formed in the bottom plate of the basement is shrunken, so that the size of the pit opening is smaller than that of the opening of the catchment cavity, and the influence of the formed pit opening on the structural rigidity and stability of the bottom plate of the basement is reduced.

Description

technical field [0001] The invention relates to the technical field of building waterproofing and drainage, in particular to a basement sump structure. Background technique [0002] In existing basement waterproof and drainage structures, sumps are often used to temporarily store sewage or miscellaneous water that needs to be discharged. The usual method is to open a large hole on the basement floor and set a sump in the hole. The side wall of the sump and the basement floor are connected by a steel bar with a bent structure, so the sump and the basement floor are integrated. Become an integral part of the basement floor, and the size of the sump area is the same as the size of the opening. [0003] There are several shortcomings in the above approach: [0004] (1) The force of the basement floor is interrupted, and the structural stability is weakened. As an integral part of the basement floor, the sump is set in the large hole opened in the basement floor, and the area ...

AI Technical Summary

Problems solved by technology

Such a setting makes the basement floor no longer a complete planar structure, and the connection between the basement floor and the side wall of the sump and the connection between the side wall of the sump and the bottom of the sump are all folded plates. The force is interrupted at the opening of the opening, causing the opening of the bottom plate to be squeezed and deformed due to the force on the ground, and the structural stability of the bottom plate is weakened

[0005] (2) Design and construction are complicated, reducing economic benefits

Due to the integrated structure of the sump pit and the basement floor, during the construction process, the construction of the reinforcement and thickness of the sump pit is affected by factors such as the reinforcement and thickness of the basement floor, resulting in the use of steel bars and concrete and other materials in many places, increasing Reduced economic cost and construction period, reduced economic benefits

In addition, when designing the construction scheme of the sump, if multiple sumps are installed, each sump in the basement floor needs to be drawn, which is cumbersome and cumbersome to design
