Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a building foundation pit drainage device. Background Art

[0002] In construction projects, the construction foundation pit is a space excavated from the ground for the construction of underground structures of buildings. During the construction of the foundation pit, groundwater, rainwater and other accumulated water enter the drainage channel through the filter at the water inlet. Generally, after the foundation pit is excavated, water is easily accumulated inside and it needs to be drained.

[0003] During foundation pit construction, groundwater seepage and rainwater accumulation are often encountered. Traditional foundation pit drainage methods have some shortcomings. For example, some simple drainage channels are easily blocked by sediment, resulting in poor drainage, making it difficult to ensure drainage efficiency and uniformity. If the accumulated water cannot be discharged in time, it will have a serious impact on the stability of the foundation pit and may even cause safety accidents. It will also have an adverse impact on the subsequent construction progress and quality. To this end, we propose a building foundation pit drainage device to solve the above problems.
