Description

Water collecting and draining device for deep foundation pit in building construction

Technical Field

Background

At present, along with the rapid development of modern building industry, high-rise and super high-rise buildings are increasingly increased, because upper load of the high-rise and super high-rise buildings is large, a compensation foundation is mostly adopted, a multi-layer basement is generally arranged to be beneficial to the stability of the building, however, the foundation burial depth is large, the foundation pit is excavated deeply, particularly when a deep foundation pit is excavated in an area with a high underground water level, a soil body water-bearing layer is cut off, underground water can continuously permeate into the foundation pit, and quicksand and side slope instability are caused or the bearing capacity of the foundation is reduced.

In order to ensure the stability of the deep foundation pit, drainage is required, and a common drainage method is open drainage of the foundation pit, namely a drainage system consisting of a drainage ditch, a water collecting well, a water delivery pipe and the like is used for draining surface water and leakage water out of the foundation pit. After the water in the foundation pit is intensively guided into the water collecting well through the drainage ditch and is temporarily stored fully, the water is pumped out through the water pump and the water delivery pipe and is discharged into an external water collecting tank. Because the foundation ditch can lead to the earth's surface aquatic to contain a large amount of silt when the construction, silt generally assembles to the sump pit in through the escape canal, forms the silt layer in the bottom of sump pit. When water is pumped from the sump by the pump, the pump is typically placed in the bottom of the sump for operation. However, when the water pump works at the bottom of the water collecting well, the water flow disturbs deposited silt, so that the silt content in water is large, and the water pump is very easy to damage.

At present, when water in the sump pit is extracted, in order to avoid the water pump to damage because of silt, generally adopt the mode that sets up the filter screen on the input port of water pump to protect. But when the water pump was drawing water at the installation filter screen, silt was deposited on the surface of filter screen easily, led to the output of water pump lower, needed operating personnel to clear up the filter screen regularly, could guarantee drainage system's work efficiency, very big increase operating personnel's work load.
