[0002] The foundation pit project mainly includes the design and construction of the foundation pit support system and earth excavation. It is a highly comprehensive system project that requires close cooperation between geotechnical engineering and structural engineering technicians. During the construction process, after the foundation pit is excavated, there will be a large amount of groundwater in the foundation pit. In order to ensure normal construction, the groundwater in the foundation pit needs to be pumped out.

[0003] The existing patent (publication number: CN213390190U) discloses a deep foundation pit drainage device, including a deep foundation pit body and a body, in which a water pump is installed, and also includes a water suction hose, a water suction port and a water discharge port, wherein the water suction port is connected to the water inlet of the water pump, and the water discharge port is connected to the water outlet of the water pump.

[0004] In the above technical solution, when the device uses a water pump and a water pump hose to extract the accumulated water in the foundation pit, the water pump hose and the filter head are easily sunk directly to the bottom of the foundation pit when placed inside the foundation pit. There is a lot of mud at the bottom of the foundation pit, so the water pump is likely to extract a large amount of mud when extracting the accumulated water, which increases the burden on the operation of the water pump.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0024] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] A foundation pit drainage structure, such as Figure 1-Figure 5 As shown, it includes a pump body 1, a pumping pipe 2 is fixedly connected to the pump body 1, and a connecting cover 3 is detachably connected to the end of the pumping pipe 2 away from the pump body 1, a water inlet 4 is provided on the top of the connecting cover 3, a filter plate 5 is fixedly connected to the center of the connecting cover 3, a cleaning mechanism for pushing mud and sand on the filter plate 5 is arranged in the connecting cover 3, a water outlet 6 is provided at the bottom of the connecting cover 3, the water outlet 6 is located below the filter plate 5, the pumping pipe 2 is detachably connected to the water outlet 6, the water inlet 4 is located at the top of the connecting cover 3, the water outlet 6 is located at the bottom of the connecting cover 3, and the middle is separated by the filter plate 5, muddy water enters from the top of the filter plate 5, so that the filter plate 5 blocks the impurities and mud in the muddy water, and prevents the muddy water from directly entering the pump body 1, thereby reducing the burden on the pump body 1, and the mud and sand accumulated on the surface of the filter plate 5 can be pushed out by the cleaning mechanism to prevent the filter plate 5 from being blocked, so that the pump body 1 can work continuously and the drainage effect is improved.

[0026] like Figure 2 As shown, the cleaning mechanism includes a push plate 7 and a threaded rod 8, the threaded rod 8 is rotatably connected to the side wall of the connecting cover 3, the push plate 7 and the threaded rod 8 are threadedly connected to each other, the push plate 7 is slidably connected to the surface of the filter plate 5, and a motor 1 is fixedly connected to the outer wall of the connecting cover 3, the output end of the motor 1 extends into the connecting cover 3 and is fixedly connected to the threaded rod 8, and the threaded rod 8 can be driven to rotate by the motor 1. Since the push plate 7 and the filter plate 5 fit each other, the push plate 7 cannot rotate, so the push plate 7 threadedly connected to the threaded rod 8 can slide on the surface of the filter plate 5, thereby pushing and cleaning the mud and impurities accumulated on the surface of the filter plate 5.

[0027] like Figure 3 As shown, a pressure plate 10 is slidably connected in the connecting cover 3, and a threaded rod 11 is rotatably connected on the side wall of the connecting cover 3. The pressure plate 10 is threadedly connected to the threaded rod 11, and the threaded rod 11 is driven by a motor 9. The motor 9 is fixed on the top of the connecting cover 3. When the thread 2 rotates, it can drive the pressure plate 10 to slide in the connecting cover 3, thereby squeezing the silt, so that the part with a larger silt concentration can also be quickly squeezed and drained. In order not to affect the normal use of the pressure plate 10 and the push plate 7, when the pressure plate 10 moves, the push plate 7 is fitted with one side of the connecting cover 3, and the push plate 7 can only operate when the pressure plate 10 returns to the top of the connecting cover 3.

[0028] The outer sides of the motor 1 and the motor 2 9 are both provided with a cover to prevent the motor 1 and the motor 2 9 from being damaged by water during use.

[0029] like Figure 1-Figure 5 As shown, a baffle 12 is fixedly connected to the water inlet 4 and the water outlet 6, and a plurality of through holes 13 are opened on the baffle 12. The baffle 12 located at the water inlet 4 can block some floating objects in the water to prevent them from entering the connecting cover 3 with the water flow. The baffle 12 located at the water outlet 6 can further filter the filtered water to reduce the possibility of mud and sand entering the pump body 1.

[0030] like Figure 4-Figure 5As shown, two clamps 14 are slidably connected at the water outlet 6 through a connecting piece, and the two clamps 14 are close to each other on one side and fit the surface of the water pumping pipe 2. The connecting piece includes a slide groove 15 opened on the connecting cover 3, and the clamp 14 is slidably connected to the slide groove 15. A spring 16 is arranged in the slide groove 15, one end of the spring 16 is fixedly connected to the slide groove 15, and the other end is fixedly connected to the clamp 14. An elastic plate 17 is arranged in the slide groove 15, and the side of the elastic plate 17 away from the slide groove 15 is fixedly connected to the clamp 14, and the water pumping pipe 2 can be clamped by the clamp 14. When the water pumping pipe 2 needs to be clamped, the clamp 14 can be pushed to make the clamp 14 push the spring 16 to deform, and then the water pumping pipe 2 is put in. After the clamp 14 is loosened, the spring 16 pushes the clamp 14 to clamp the water pumping pipe 2. The elastic plate 17 is arranged on the top of the slide groove 15 and is connected to the clamp 14, so as to protect the spring 16 from being eroded by muddy water during the water pumping process.

[0031] The normal use of this utility model is as follows:

[0032] When it is necessary to pump water, first push the clamp 14 to make the clamp 14 push the spring 16 to deform, then put in the pumping pipe 2, and after loosening the clamp 14, the spring 16 pushes the clamp 14 to clamp the pumping pipe 2, so that the pumping pipe 2 is connected to the connecting cover 3, and then the connecting cover 3 can be put into the foundation pit for pumping water. During the pumping process, the muddy water passes through the baffle 12, the filter plate 5 and another baffle 12 in turn, which can separate the mud and sand in the muddy water, thereby preventing the mud and sand from entering the pump body 1 and affecting the normal pumping of the pump body 1. After a period of use, the push plate 7 can slide on the surface of the filter plate 5 to prevent the filter plate 5 from being blocked, thereby ensuring the sustainable use of the connecting cover 3.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
