Description

Technical Field

[0001] The invention relates to the technical field of drainage equipment and methods for high-water-level ultra-deep foundation pits, and in particular to drainage equipment and methods for high-water-level ultra-deep foundation pits. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. During the foundation pit excavation stage, water will accumulate at the bottom of the foundation pit, especially in deeper foundation pits, where a large amount of water will accumulate. It is necessary to use the foundation pit drainage system to lower the water level at the bottom of the foundation pit to ensure the smooth progress of earthwork excavation. Otherwise, long-term water accumulation in the foundation pit will cause the foundation pit to collapse.

[0003] In the prior art, the drainage of foundation pits is mostly done by using a water pump to extract the accumulated water in the foundation pit through a pumping pipe, and then discharging it from the drainage pipe of the water pump to ensure the smooth progress of earth excavation.

[0004] However, the silt content in the accumulated water in the foundation pit is relatively high. Usually, a filter cartridge is installed at the end of the water pump suction pipe to filter the silt. However, after working for a long time, the silt can easily clog the filter screen of the filter cartridge, resulting in low pumping efficiency, which seriously affects work efficiency. Summary of the invention

[0010] Preferably, an extrusion block is provided at one end of the connecting plate, and the extrusion block can squeeze the telescopic plate through the rotation of the connecting plate, so that the telescopic rod drives the telescopic plate to stretch the spring connected inside, so that the telescopic plate is held on the inner surface of the filter.

[0011] Preferably, a rotating groove is opened around the outer side of the filter cylinder, and the rotating groove is opened on the inner side of the filter screen. A brush plate is arranged in the rotating groove, and bristles are arranged on the brush plate.

[0013] Preferably, the water pump body can extract the accumulated water in the foundation pit through a pumping pipe, and then discharge the extracted accumulated water through a drainage pipe connected to the top.

[0014] A method for using a drainage device for a high water level ultra-deep foundation pit comprises the following steps:

[0015] Step 1: Cleaning. The motor in the motor slot opened in the middle of the bottom base of the filter cartridge starts to control the rotation of the shaft, so that the shaft drives the connecting plate connected to the top to rotate, so that one end of the shaft passes through the plug ring and is inserted into the brush plate connected in the rotating slot to start rotating.

While the brush plate rotates in the rotating slot, the bristles on the outer side of the brush plate begin to press against the inner surface of the filter screen, and start to clean the mud and debris stuck on the filter screen to prevent the mud and debris from clogging the filter screen. When the stone and debris in the mud are stuck on the filter screen, the brush plate will be removed. When the brush plate in the mesh opening cannot clean out the stones, the connecting plate rotates to drive the extrusion block set at the other end of the connecting plate to start squeezing the telescopic plate, so that the telescopic rod stretches the spring in the telescopic groove, driving the telescopic plate to hold the surface of the filter, and at the same time, multiple groups of extrusion heads set on the outer surface of the telescopic plate are inserted into the mesh opening of the filter to push out the debris fixed in the mesh opening of the filter to prevent it from clogging the mesh opening of the filter; finally, the accumulated water pumped out by the water pump body through the suction pipe is discharged through the drain pipe connected to the top of the water pump body to achieve drainage of the foundation pit.
