Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit dewatering and drainage, in particular to a bridge culvert foundation pit dewatering and drainage device. Background Art

[0002] The construction of bridges and culverts requires the excavation of foundation pits. Rain during the construction of foundation pits will cause water accumulation in the pits. Drainage needs to be carried out immediately after the rain stops, otherwise construction will be impossible and even cause the foundation pit to collapse. At present, pumps are generally used for drainage, but the current pumps still have the following problems when draining water:

[0003] The existing pumping pipes of pumps mostly rely on adding filter covers to filter impurities and silt in the foundation pit water. However, the current filter covers sink directly to the bottom of the foundation pit when in use, which easily absorbs silt, causing the filter holes to be blocked and affecting the pumping efficiency. Therefore, we propose a bridge culvert foundation pit dewatering and drainage device. Utility Model Content
