Description

Technical Field

[0001] The present application relates to the technical field of foundation pit drainage, and in particular to a foundation pit drainage structure. Background Art

[0002] The foundation pit refers to the space below the ground excavated for the construction of building foundations and basements. Since the groundwater level is higher than the bottom of the excavation, groundwater will continuously seep into the foundation pit. In order to ensure that the foundation pit can be constructed under dry conditions and prevent slope instability, pit bottom uplift and decreased foundation bearing capacity, it is necessary to drain the foundation pit.

[0003] Foundation pit drainage refers to the method of using a water pump to drain the accumulated water inside the foundation pit during construction or water conservancy projects in order to ensure that the inside of the foundation pit is dry and prevent the accumulation of water from having adverse effects on the structure and quality of the building.

[0004] Since a lot of silt often accumulates in the foundation pit, it is easy for the silt to flow into the water pump during the drainage process, causing the water pump to be blocked and affecting the drainage efficiency. To solve this problem, the foundation pit drainage system usually installs a special filter at the water pump's suction pipe to intercept the silt and protect the water pump from being blocked. However, as time goes by, the filter will gradually be blocked by silt, reducing the drainage effect. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] The top of the drainage hole is provided with an annular mounting cover, and a filter is installed inside the drainage hole. The top of the annular mounting cover is fixedly connected with an adjusting mounting frame, the adjusting mounting frame is internally slidably connected with a base, and the top of the base is fixedly connected with a driving motor, the adjusting mounting frame is internally rotatably connected with an inverted T-shaped sleeve rod, one end of the inverted T-shaped sleeve rod extends to the inside of the base and is movably connected with the base, the inside of the inverted T-shaped sleeve rod is internally slidably connected with an active rod, the output end of the driving motor passes through the base and is fixedly connected with the active rod, one end of the inverted T-shaped sleeve rod is symmetrically rotatably connected with a brush rod, the inner bottom of the drainage hole is fixedly connected with a drainage pipe, and one end of the drainage pipe is fixedly connected with a drainage pump, the inside of the inverted T-shaped sleeve rod is provided with a guide assembly for guiding the inverted T-shaped sleeve rod and the active rod to rotate synchronously, and the inner side of the annular mounting cover is provided with a transmission assembly for driving the brush rod to rotate.

On one hand, the brush rod effectively improves the brushing effect of the brush rod on the sediment adhered to the inner wall of the filter screen, and reduces the problem of the inner wall of the filter screen being blocked by sediment and resulting in a decrease in the filtering effect.

[0009] Furthermore, the guide assembly includes a synchronous slide groove symmetrically opened on the inner side of the inverted T-shaped sleeve rod, one end of the active rod is symmetrically fixedly connected with a synchronous slider, and the synchronous slider is slidably connected inside the synchronous slide groove.

[0019] Furthermore, a truncated cone is fixedly connected to the inner bottom of the drainage well, a sedimentation tank is formed between the truncated cone and the bottom of the drainage well, and one end of the drainage pipe passes through the truncated cone and extends to the interior of the drainage well.

One end of the locking screw 16 passes through the through slot 17 and is threadedly connected with a locking nut 18.

[0039] During use, when the water level inside the foundation pit is high, the fixed connection between the base 5 and the adjusting mounting frame 4 is released by manually loosening the locking nut 18, and then the base 5 is pulled upward along the length direction of the through slot 17 to drive the drive motor 6 to break away from the water level line inside the foundation pit, and then the locking nut 18 is tightened, so that the locking nut 18 is moved closer to one side of the adjusting mounting frame 4 along the length direction of the locking screw 16, thereby forming a fixed connection between the base 5 and the adjusting mounting frame 4, thereby facilitating the adjustment of the height of the drive motor 6 along the length direction of the through slot 17 according to the actual water level, effectively improving the scope of application of the device.
