When excavating a foundation pit in a construction project, if the groundwater level is high and the surface height of the basement is below the groundwater level, it needs to be dewatered to ensure subsequent construction. The foundation pit drainage is mainly divided into the open drainage method and the well point precipitation method. The method is the most common and applied, but the most unnegligible problem of the drainage method in the Ming Dynasty is that there is often a large amount of silt mixed in the sump. Install a filter device, but in the process of use, it will be found that a large amount of sediment will block the filter device, which seriously affects its overall use effect

The invention discloses a deep foundation pit drainage device. The deep foundation pit drainage device comprises a pump box (1), wherein a driving cavity is separated from one side of the pump box (1)through a partition plate (2); a driving rod (3) is arranged in the middle of the pump box (1); a sliding rail (4) arranged in the length direction of the driving rod (3) is arranged on one side of the driving rod (3); a guide sliding groove (28) which can be in clearance sliding fit with the sliding rail (4) is formed in the partition plate (2); a driving device used for driving the driving rod(3) is arranged in the driving cavity; two sets of symmetrical water pumping devices are arranged in the pump box (1); and each water pumping device comprises a first driving connecting rod (5). The deep foundation pit drainage device is simple in structure, silt in a water collecting pit can be effectively filtered out through a natural sedimentation method in the interval of alternate drainage,and the phenomenon of blockage caused by use of a filter plate is avoided.
Description
technical field [0001] The invention relates to the technical field related to drainage, in particular to a deep foundation pit drainage device. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. When excavating a foundation pit in a construction project, if the groundwater level is high and the surface height of the basement is below the groundwater level, it needs to be dewatered to ensure subsequent construction. The foundation pit drainage is mainly divided into the open drainage method and the well point precipitation method. The method is the most common and applied, but the most unnegligible problem of the drainage method in the Ming Dynasty is that there is often a large amount of silt mixed in the sump. Install a filter device, but in the process of use, it will be found that a large amount of sand will block the filter device, which seriously affect...
