[0002] The civil construction foundation pit drainage structure is suitable for the internal drainage of the foundation pit dug during the construction of the subway station. The subway station needs to dig a foundation pit during construction. Therefore, when the groundwater level is higher than the ground inside the foundation pit, the groundwater will continuously seep into the foundation pit, affecting the internal construction of the foundation pit. The civil construction foundation pit drainage structure is conducive to maintaining the dryness of the internal environment of the foundation pit and preventing safety hazards such as slope collapse and quicksand caused by the infiltration of water inside the foundation pit. The subway station needs to drain the foundation pit during construction. The drained water usually contains mud and sand. During the drainage process, the mud and sand are easily deposited at the bottom of the drainage pipe. Long-term accumulation can easily cause blockage of the drainage pipe, affecting the drainage efficiency. Utility Model Content

[0032] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.
[0033] like Figure 1-5As shown, a drainage structure for a foundation pit of a subway station civil construction comprises a drainage pipe body 1 and a driving motor 2. A mesh filter plate 11 is installed inside the drainage pipe body 1, and a grid filter plate 12 is installed on the top of the drainage pipe body 1. A drainage bottom plate 3 is installed at the bottom of the drainage pipe body 1. The driving motor 2 is installed at the bottom of the drainage pipe body 1, and a driving gear 21 is connected to the output end of the driving motor 2. A driven gear 22 is meshed and connected above the driving gear 21. A rotating shaft 23 is installed on the driven gear 22, and stirring and water-discharging plates 24 are circumferentially installed on both sides of the rotating shaft 23. A synchronous belt 25 is installed at a position of the rotating shaft 23 near the driven gear 22. The driving motor 2 drives the rotating shaft 23 to rotate through the driving gear 21 and the driven gear 22. The rotation of the rotating shaft 23 can drive the stirring and water-displacing plate 24 to rotate. The rotation of the stirring and water-displacing plate 24 can stir the seepage inside the drainage bottom plate 3, reduce the sedimentation of the seepage water, and make the sediment flow into the collection pool with the water, thereby avoiding the blockage of the drainage pipe and ensuring the efficiency and effect of drainage. The driven gear 22 and the rotating shaft 23 adopt an axial overlap setting, which can make it more reliable when the driven gear 22 drives the rotating shaft 23 to rotate. The rotating shaft 23 and the drainage bottom plate 3 are connected with a bearing, which can effectively reduce the friction of the rotating shaft 23 when the rotating shaft 23 rotates, thereby making the rotation of the rotating shaft 23 more reliable and stable. The rotating shaft 23 and the drainage pipe body 1 are arranged in parallel with each other, which can make the rotating shaft 23 drive the stirring and water-discharging plate 24 to rotate more stably and reliably. The cross section of the drainage bottom plate 3 is arranged in a "W" shape, which can make the drainage bottom plate 3 divert the seepage water, making the drainage bottom plate 3 smoother when draining. The driving gear 21 and the driven gear 22 are arranged in the same horizontal The grid filter plate 12 is overlapped on the top of the drainage pipe body 1, and the overlapping method can make the grid filter plate 12 convenient and quick to remove and clean from the drainage pipe body 1, thereby making the cleaning of the grid filter plate 12 more convenient and quick. The mesh filter plate 11 and the drainage pipe body 1 are arranged parallel to each other, and the top of the mesh filter plate 11 is provided with bumps at equal intervals. The parallel arrangement can make the mesh filter plate 11 more convenient for filtering the seepage water, and the bumps can facilitate the seepage water to pass through the mesh holes into the drainage bottom plate 3 for discharge.
[0034] The working principle of the utility model is as follows: the device is installed at a designated position, and the seepage water in the foundation pit enters the drainage bottom plate 3 through the grid filter plate 12 and the mesh filter plate 11 and then flows into the collection pool. The grid filter plate 12 cooperates with the mesh filter plate 11 to filter larger particles to avoid clogging of the drainage bottom plate 3 during drainage. Since the seepage water usually contains sediment, the sediment is easy to settle at the bottom of the drainage bottom plate 3 when flowing through the drainage bottom plate 3. The driving motor 2 drives the rotating shaft 23 to rotate through the driving gear 21 and the driven gear 22. The rotation of the rotating shaft 23 can drive the stirring and water-displacing plate 24 to rotate. The rotation of the stirring and water-displacing plate 24 can stir the seepage water inside the drainage bottom plate 3, reduce the sedimentation of the sediment in the seepage water, and make the sediment flow into the collection pool with the water, thereby avoiding clogging of the drainage pipe and ensuring the efficiency and effect of drainage.
