Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a foundation pit drainage device for building construction. Background Technology

[0002] Dewatering the foundation pit is a crucial step in foundation pit construction, primarily aimed at controlling the groundwater level and ensuring construction safety and foundation stability. Large drainage pumps are typically used for this purpose. However, due to the uneven ground at the bottom of the pit, numerous small puddles form. While a handheld submersible pump (model from Taizhou Jianshi Electromechanical Co., Ltd.) is used to pump water out of these puddles, although a filter cartridge at the bottom of the pump prevents debris from being sucked into the pump body, some debris adheres to the outside of the filter cartridge, affecting its water absorption efficiency.
