Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5, the present utility model provides a technical solution: a leakage plugging and drainage device for the water-stop curtain of a deep foundation pit, including a water-stop pile 1. There is a groove 4 on one side of the water-stop pile 1. An installation block 13 is fixedly connected to the inner wall of the groove 4. The installation block 13 is concave-shaped. There is an installation groove 14 inside the installation block 13. A filter plate 5 is arranged in the groove 4. The outer side of the filter plate 5 is movably inserted into the installation groove 14. A baffle 10 is fixedly connected to the inner wall of the groove 4. A water outlet pipe 2 is arranged at the bottom end of the baffle 10. The water outlet pipe 2 penetrates the water-stop pile 1. One end of the water outlet pipe 2 located in the groove 4 is sleeved with a protective sleeve 9. The other end of the water outlet pipe is fixedly connected to a drain pipe 3. A limiting mechanism 7 is arranged at the upper end of the water-stop pile 1. By allowing water to flow into the sedimentation tank 12, and then through an external water pump device, the drain pipe 3 and the water outlet pipe 2, the water is discharged into the nearby sewer, preventing a large accumulation of water flow near the water-stop pile 1, ensuring the safety of the foundation pit, and reducing the burden on the water-stop pile 1.

[0019] A number of insertion blocks 6 are fixedly connected to one side of the water-stop pile 1. A number of slots 15 adapted to the insertion blocks 6 are arranged on the other side of the water-stop pile 1. A connection groove 16 is arranged at the upper end of the water-stop pile 1 close to the drain pipe 3. A connecting plate 8 is arranged on one side of the connection groove 16. The connecting plate 8 is concave-shaped. One side of the connecting plate 8 is movably inserted into the connection groove 16. According to actual needs, multiple water-stop piles 1 can be spliced together. The insertion blocks 6 and the slots 15 of two adjacent water-stop piles 1 are combined with each other. Then, through the concave-shaped connecting plate 8 and the connection grooves 16 on the outer sides of the two water-stop piles 1, the two water-stop piles 1 are stably spliced together. The limiting mechanism 7 includes a pulling block 71, a fixing block 72, two connecting rods 73, a magnetic block 74 and a limiting rod 75. The fixing block 72 is fixedly connected to the upper end of the water-stop pile 1. A pulling block 71 is arranged on one side of the fixing block 72. A limiting rod 75 is arranged on the other side of the fixing block 72. The limiting rod 75 and the pulling block 71 are fixedly connected by two connecting rods 73. Both of the two connecting rods 73 are movably sleeved with the fixing block 72. The limiting rod 75 is located above a number of slots 15. A magnetic block 74 is fixedly connected to the side of the limiting rod 75 away from the fixing block 72. Push the pulling blocks 71 at the upper ends of the two water-stop piles 1. The pulling blocks 71 push the limiting rod 75 to move horizontally through the connecting rods 73. The two magnetic blocks 74 are magnetically connected to each other, so that the two limiting rods 75 are connected together, and the two limiting rods 75 are located above the slots 15 and the insertion blocks 6 to limit the insertion blocks 6, ensuring the connection stability of the two water-stop piles 1. A number of convex blocks 17 are evenly and fixedly arranged on the outer side of the filter plate 5. A lifting ring 18 is fixedly connected to the top end of the filter plate 5. The convex blocks 17 intercept sundries in the water flow. A side plate 11 is fixedly connected to one side of the bottom end of the groove 4. A sedimentation tank 12 is arranged between the side plate 11 and the inner wall of the groove 4. The water flow is concentrated in the sedimentation tank 12, and the impurities in the water flow are precipitated through the sedimentation tank 12.

[0020] Specifically, when the utility model is in use, multiple water-stop piles 1 can be spliced together according to actual needs. The insertion blocks 6 and the slots 15 of two adjacent water-stop piles 1 are combined with each other, and then the concave connecting plate 8 is combined with the connecting grooves 16 on the outer sides of the two water-stop piles 1, so that the two water-stop piles 1 are stably spliced together. After the splicing is completed, the pulling blocks 71 at the upper ends of the two water-stop piles 1 are pushed. The pulling blocks 71 push the limiting rods 75 to move horizontally through the connecting rods 73, and the two magnetic blocks 74 are magnetically connected to each other, so that the two limiting rods 75 are connected together, and the two limiting rods 75 are located at the upper ends of the slots 15 and the insertion blocks 6 to limit the insertion blocks 6 and ensure the connection stability of the two water-stop piles 1; the water flow passes through the filter plate 5 and flows into the groove 4. The filter plate 5 intercepts impurities in the water flow, and the water flow in the groove 4 will be concentrated in the sedimentation tank 12. The water flow precipitates the impurities in the sedimentation tank 12. When the water flow in the sedimentation tank 12 reaches a certain amount, the water flow flows into the drain pipe 3 through the water outlet pipe 2, and finally the water flow in the drain pipe 3 is discharged into the nearby sewer through an external water pump device, preventing the water flow near the water-stop pile 1 from accumulating too much, ensuring the safety of the foundation pit and reducing the burden on the water-stop pile 1.
