Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pit drainage, and in particular relates to a civil construction foundation pit drainage structure. Background Art

[0002] At present, when excavating foundation pits, trenches, pipe trenches or other earthworks, the soil aquifer is often cut off, and groundwater will continue to seep into the pit. During construction in the rainy season, surface water will also flow into the pit. In order to ensure the normal progress of construction and prevent slope collapse and the decline of foundation bearing capacity, foundation pit dewatering must be done well. Dewatering methods are divided into two categories: drainage method and artificial lowering of groundwater level method.

[0003] The prior art discloses a drainage structure for a foundation pit of a civil engineering project with a patent announcement number of CN219931037U. The patent includes a water collection well for collecting the accumulated water in the foundation pit. The inner wall of the water collection well is provided with a plurality of partition plates, which are arranged in sequence and spaced apart, and the partition plates divide the inner part of the water collection well into a plurality of water storage chambers; the partition plates are provided with a screen for filtering the sediment in the accumulated water; an inlet pipe is provided on the inner wall of the water storage chamber on one side of the water collection well, and a water pump is placed in the water storage chamber on the other side of the water collection well. The present application has the effect of extracting the clear accumulated water by a water pump, and the filtered accumulated water can meet the demand for reuse of water resources, thereby reducing the waste of water resources. However, the following deficiencies still exist in actual use: from a practical point of view, the accumulated water is introduced through the inlet pipe in the patent. Usually, there is a lot of sediment in the accumulated water in the foundation pit, which is easy to cause the inlet pipe to be blocked. At the same time, the sediment filtered in the water collection tank is not easy to be cleaned in time, and the accumulation is easy to cause the water storage efficiency of the water collection tank to be reduced.

[0004] Therefore, a civil engineering foundation pit drainage structure is needed to solve the problems in the prior art of easy silt blockage and inconvenience in cleaning silt, resulting in reduced water storage efficiency. Utility Model Content

[0022] The cleaning mechanism 4 facilitates the cleaning of filtered sediment and improves the filtering efficiency. Meanwhile, the filtering mechanism 7 enhances the filtering capacity of accumulated water and cooperates with the pump 6 to facilitate the reuse of water resources.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the cover plate 2 slides on the top of the water collecting box 1 through the limiting strip 201 and the sliding groove 202.

[0024] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that the cleaning mechanism 4 includes two support plates 401, and the two support plates 401 are symmetrically fixedly connected to the top of the water collecting tank 1. A motor 402 is fixedly installed on the top of the rear support plate 401, and a threaded rod 403 is fixedly connected to the output end of the motor 402. The threaded rod 403 rotates on the support plate 401 through a bearing, and a threaded sleeve 404 is threadedly connected to the bottom of the threaded sleeve 404. A fixed block 407 is fixedly connected to the bottom of the threaded sleeve 404, and a sliding rod 404 is fixedly connected to the front support plate 401. 09, the bottom of the slide rod 409 is slidably connected to a sleeve 408, the bottom of the sleeve 408 is fixedly connected to another fixed block 407, a filter frame 405 is fixedly connected between the two fixed blocks 407, the threaded sleeve 404 and the upper part of the sleeve 408 are fixedly connected to a top plate 406 and are arranged on the upper part of the filter frame 405, the top plate 406 is arranged in a convex plate, the threaded sleeve 404 and the sleeve 408 pass through the top plate 406, and the top plane of the top plate 406 can be arranged flush with the top plane of the cover plate 2 through the threaded rod 403 and the slide rod 409.

[0025] The operation of the motor 402 drives the threaded rod 403 to rotate, so that the threaded rod 403 rotates in the threaded sleeve 404 to drive the threaded sleeve 404 to rise, and at the same time, the sliding rod 409 slides in the sliding sleeve 408 to lift the filter frame 405, and at the same time, the top plate 406 is lifted, so as to clean the sediment in the filter frame 405 and improve its filtering efficiency.

[0026] According to the above working process, it can be known that: through the provided cleaning mechanism 4, the filtered sediment can be quickly cleaned to improve the water storage efficiency inside the water collecting box 1, while avoiding sediment blockage and further improving the filtering effect.

[0027] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the filtering mechanism 7 includes a baffle 703, the baffle 703 is fixedly connected in the water collecting tank 1 and is arranged on the right side of the filter frame 405, a through opening 705 is opened at the lower part of the baffle 703, a partition 701 is fixedly connected to the right side of the baffle 703 in the water collecting tank 1, a water-permeable membrane 702 is fixedly installed on the upper part of the partition 701, a filter plate 704 is fixedly connected between the baffle 703 and the partition 701 and on the upper part of the through opening 705, and the through opening 705 is set at a height less than the height of the filter frame 405.

[0028] The accumulated water is first filtered through the filter frame 405 to filter and collect the silt, and then filtered again through the filter plate 704. When the left side of the partition 701 is almost full, the accumulated water is filtered again to the right side of the partition 701 through the permeable membrane 702. At this time, the silt in the accumulated water has been filtered out, and the pump 6 is operated to allow the water to be pumped out through the drain pipe 5 for use, thereby improving the utilization rate of water resources.

[0029] This solution has the following working process: when this device is used, the accumulated water is discharged into the water collecting box 1 through the drainage channel 3. The accumulated water is first filtered through the filter frame 405 to filter and collect the silt, and then filtered again through the filter plate 704. When the left side of the partition 701 is almost full, the accumulated water is filtered again to the right side of the partition 701 through the permeable membrane 702. At this time, the silt in the accumulated water has been filtered, and the pump 6 is operated to make the water pumped out through the drainage pipe 5 for use. When it is necessary to clean the silt in the filter frame 405, the motor 402 is operated to drive the threaded rod 403 to rotate, so that the threaded rod 403 rotates in the threaded sleeve 404 to drive the threaded sleeve 404 to lift, and at the same time, the sliding rod 409 slides in the sliding sleeve 408 to lift the filter frame 405, and at the same time, the top plate 406 is lifted to facilitate the cleaning of the silt in the filter frame 405 and improve its filtering efficiency.
