Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit drainage, in particular to a structure for quickly reducing the local water level of a foundation pit. Background Technique

[0002] In the construction of foundation pit projects, when the groundwater level is higher than the excavation ground surface, due to the cutting off of the aquifer, under the influence of the pressure difference, groundwater will continuously seep into the pit, causing problems such as waterlogging in the foundation pit, instability of the slope, and sand gushing at the bottom of the pit. Foundation pit dewatering refers to pumping groundwater within a certain range and depth to lower the groundwater level within a specific range below the excavation surface. The extracted groundwater is discharged into the municipal pipeline or open channel, river, etc. through the drainage pipeline, or is used for the construction project.

[0003] When the common foundation pit is drained, the water extraction pipe is installed at the bottom of the foundation pit and cooperates with the water pump to quickly discharge the water body inside the foundation pit, so that the water level inside the foundation pit drops. However, since the water pump drains the entire foundation pit when pumping water, the water level drop speed inside the foundation pit is slow, and the water level at a single end position inside the foundation pit cannot be quickly reduced, resulting in poor practicability of the foundation pit drainage and inability to meet the working requirements of the foundation pit drainage. Therefore, a structure for quickly reducing the local water level of the foundation pit is proposed. Content of the Utility Model
