Drainage system for building foundation pit construction

Abstract

The invention relates to the field of buildings, in particular to a drainage system for foundation pit construction of buildings. The system includes an airbag, a fixing structure, a drainage structure, a first filtering structure, a driving structure, a water level control structure and a second filtering structure. The airbag is used for floating on the water surface; the fixing structure is used for protecting the drainage structure; the first filtering structure and the second filtering structure are used for filtering sewage; the drainage structure is used for achieving a drainage function; the driving structure and the water level control structure are used for controlling the connection and disconnection states of the drainage structure according to the water level. The driving structure cooperates with the water level control structure to control the connection and disconnection states of the drainage structure, the buoyancy of a water source is effectively utilized, the drainage structure is visibly and accurately controlled to work, and energy waste during construction is avoided. Large gravel garbage is primarily filtered out through the first filtering structure, sewagein a foundation pit is filtered out through the second filtering structure, the drainage efficiency is greatly improved, and blockage of the drainage structure is prevented. Meanwhile, in cooperativeuse of the airbag, a device can float on the water surface of the foundation pit, and the drainage quality is improved.

Description

technical field [0001] The invention relates to the construction field, in particular to a drainage system for building foundation pit construction. Background technique [0002] The foundation pit refers to the space below the ground excavated for the construction of the building foundation and the basement. During the construction of the foundation pit, after the excavation is combined with the conditions of the nearby buildings on the site, waterproof and drainage work is done. The drainage system refers to the drainage system. The overall collection, transportation, water quality treatment and discharge facilities are combined in a certain way. The use of drainage devices effectively protects the slope of the foundation pit, improves the quality of construction, and reduces the difficulty of construction. [0003] However, the traditional foundation pit construction drainage uses the direct pumping method to drain water. During the drainage process, the water pump will c...

Problems solved by technology

[0003] However, the traditional foundation pit construction drainage uses the direct pumping method to drain water. During the drainage process, the water pump will continue to work after the water in the foundation pit is removed, which wastes energy and affects the performance of the pump. During the drainage process, the filter at one end of the pump It is easy to directly contact with the silt inside the foundation pit, which may easily cause the blockage of the filter screen and affect the drainage performance, and at the same time, it is easy to damage the water pump
