[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example: Reference Figure 1-7 The device for treating leakage on the sidewall of a foundation pit shown includes a sealing and fixing assembly 1 and a flow guiding assembly 2 disposed on the sealing and fixing assembly 1. The sealing and fixing assembly 1 includes a fixing member 11 and a sealing cone 12. The sealing cone 12 is rotatably disposed on the fixing member 11 and is hollow inside. The sealing cone 12 is composed of a cylindrical section and a conical section. A water inlet hole 123 is opened through the tip of the conical section. Spiral lines 122 are opened on the outer surface of the sealing cone 12 for connecting and fixing with the sidewall of the foundation pit. The flow guiding assembly 2 includes a fixing plate 21 and a flow guiding member 23. The fixing plate 21 is disposed inside the sealing cone 12, and the fixing plate 21 and the inner side of the conical section form a buffer cavity 211 for temporarily storing the seeping water. An external threaded pipe 22 is disposed through the middle of the fixing plate 21. The flow guiding member 23 is disposed on the external threaded pipe 22, and the external threaded pipe 22, the water inlet hole 123 and the sealing cone 12 are coaxially arranged.

[0027] The fixing component 11 includes a support plate 111, and a sealing cone 12 is rotatably disposed in the middle of the support plate 111. Multiple through holes 112 are evenly opened on the support plate 111. Anchor rods 113 are installed in the through holes 112. The anchor rods 113 are used to connect with the side wall of the pit to fix the support plate 111 to the side wall of the pit. The anchor rods 113 can be pre-positioned and fixed. Only the outermost through holes 112 on both sides of the sealing cone 12 are used. Rivets are installed in the other through holes 112 for further fixation, which can reduce costs and improve the economic efficiency of construction.

[0028] In this device, several rotating rods 121 are evenly arranged circumferentially on the outer side of the end of the sealing cone 12 that is away from the cone section. The rotating rods 121 are located on the side of the support plate 111 away from the pit sidewall. They are used to control the rotation of the sealing cone 12 on the support plate 111. By rotating the rotating rods 121, the sealing cone 12 is driven to rotate. The rotation direction of the sealing cone 12 is the screw-in direction of the spiral thread 122, so as to thread and fix the sealing cone 12 to the pit sidewall, thereby improving the practicality and stability of the device.

[0029] Among them, an annular plate 221 is provided on the outer side of the end of the external threaded pipe 22 away from the fixed plate 21. A sealing ring 222 is fitted on the external threaded pipe 22 on the side of the annular plate 221 close to the fixed plate 21. The sealing ring 222 is used to prevent water from flowing out of the buffer chamber 211, thereby improving the safety of the device.

[0030] The guide component 23 includes a guide tube 231 and a connecting tube 232. The guide tube 231 is slidably disposed through the middle of the external threaded tube 22. The connecting tube 232 is disposed outside the guide tube 231 and can rotate with the rotation of the guide tube 231. The end of the connecting tube 232 near the fixed plate 21 is provided with an internal threaded tube 233. The internal threaded tube 233 is threadedly connected to the external threaded tube 22. The connecting tube 232 can drive the internal threaded tube 233 to move on the external threaded tube 22. The movement of the internal threaded tube 233 on the external threaded tube 22 is used to compress the sealing ring 222, further improving the sealing performance.

[0031] The guide pipe 231 is equipped with a rotating component 2311 to drive the guide pipe 231 to rotate. The rotating component 2311 adopts a nut-like structure with a regular hexagonal cross-section, which facilitates the operator to rotate it with tools when rotation is needed and avoids misoperation when rotation is not needed, thus improving the safety of the device. Several annular grooves 2312 are opened on the pipe wall of the guide pipe 231 near the water inlet 123. Several water flow holes are evenly opened in the annular grooves 2312. The water flow holes are used to connect the buffer chamber 211 and the inner cavity of the guide pipe 231 to draw out the water in the buffer chamber 211. The annular grooves 2312 prevent other debris from blocking the water flow holes, thus improving the practicality of the device.

[0032] The end of the guide pipe 231 near the water inlet hole 123 is set as a cone, and the size of the cone matches the size of the water inlet hole 123. It is used to slide and insert into the water inlet hole 123 to prevent the mud from blocking the water inlet hole 123 when the sealing cone 12 enters the seepage position, thus improving the practicality of the device.

[0033] Working principle of this utility model:

[0034] First, the location of the leaking hole on the sidewall of the foundation pit is determined. Then, the leaking hole is enlarged into a cone shape. Next, the sealing cone 12 is inserted and the water inlet 123 is aligned with the determined leaking hole location. The anchor rod 113 is first fixed to the pit wall through the through hole 112 for positioning. Then, the rotating rod 121 is operated to rotate the sealing cone 12, and the spiral thread 122 is used to fix the sealing cone 12 at the leaking hole location. Then, the anchor rod 113 is inserted into the inner wall of the foundation pit for further fixation. Finally, the guide pipe 231 is rotated by the rotating component 2311, so that the internal threaded pipe... As the threaded pipe 233 moves outward on the external threaded pipe 22, the cone of the guide pipe 231 will move away from the inlet hole 123, allowing the water from the leak to flow into the buffer chamber 211. At the same time, the mud and sand in the water sink to the bottom of the buffer chamber 211 under the action of gravity. The leaked water enters the guide pipe 231 through the water outlet and is discharged outward, completing the seepage treatment. This allows the guide pipe 231 to be suspended, preventing the mud from blocking the water outlet of the guide pipe 231 after long-term use. At the same time, it makes the treatment of leakage simpler, more timely and convenient, and helps to save construction time.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
