Description

Basement drainage structure

Technical Field

The application relates to the technical field of engineering construction, in particular to a basement drainage structure.

Background

High-rise and super high-rise buildings are increasing, because of large upper load, the high-rise buildings are generally provided with a multi-layer basement as a compensatory foundation to facilitate the stability of the buildings, and measures such as soil retaining structures, underground water control, environmental protection and the like required for ensuring the safety and stability during the construction of underground structures are called foundation pit engineering.

However, high-rise buildings need foundations with large burial depths, and underground water and ground water can continuously infiltrate into foundation pits when basement deep foundation pits are excavated, so that quicksand and side slopes are unstable, or the bearing capacity of the foundations is reduced. The waterproof mode that generally adopts at the foundation ditch bottom surface setting drainage well of the drainage of foundation ditch, the lateral wall intercommunication of drainage well has the inlet tube, directly extracts through the water pump through the water that the inlet tube flowed into in the drainage well. However, underground water may have more bulky silt and soil blocks, which may flow into the drainage well from the underground water inlet pipe, and garbage generated in the construction process may also flow into the drainage well from the above-ground water inlet pipe, which may cause the blockage of the water pumping part of the water pumping pump.

Therefore current deep basal pit drainage system can set up the filter screen thereby the water in the sump pit filters before the water pump removes bulky impurity, but along with the operation of drawing water of water pump, often can adhere to more bold impurity on the filter screen, though can not lead to the fact the jam to pump body inside, but can cause the discharge to reduce, leads to the stagnation of drainage operation, influences work efficiency.
