The anti-seepage of the basement sump floor is often the pain point and difficulty of waterproof construction. Before pouring the basement floor, if the leakage treatment of the floor is not in place, it will affect the normal use of the basement. When leakage problems occur on the floor, only by pumping water and other methods to drain the accumulated water and then re-pouring concrete, it is impossible to timely plug the leakage points, further causing more serious water seepage, which is not conducive to the subsequent plugging of the sump, resulting in local leakage, damp walls and floors even after maintenance.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 shown, in Embodiment 1, a leak plugging device for a basement sump includes a bottom plate 1 that cooperates with the sump. A pressure relief valve group 3 is installed on the bottom plate 1, and a suspension connecting piece for assisting the movement of the bottom plate 1 is provided above the bottom plate 1. The bottom plate 1 cooperates with the sump as a plugging member and is also used to assist in plugging the sump. The pressure relief valve group 3 is used for auxiliary pumping of the sump to facilitate the plugging treatment. The suspension connecting piece is used to assist the bottom plate 1 to enter the sump to realize auxiliary drainage during the falling process of the bottom plate 1. It is simple to manufacture, has a low cost investment, and can be manufactured according to the actual size of the leakage area of the project, and can be flexibly adjusted according to the actual construction conditions of the project. It can better improve the construction quality of the waterproof grouting material at the leakage point, and at the same time reduce the secondary repair caused by problems such as poor construction environment of the waterproof grouting material in the later stage, and save more secondary repair costs.

[0022] Specifically, when in use, the pressure relief valve group 3 is installed according to actual needs. First, connect the pressure relief valve group 3 to the existing pumping device, and then the staff connects the lifting rope to the suspension connecting piece, and puts the bottom plate 1 into the sump through the suspension connecting piece, and starts the pumping device to drain the sump. After the drainage is completed, the staff stands on the bottom plate 1 to plug the leakage position of the sump under the bottom plate 1. After the plugging is completed, the pumping device is removed, and finally the sump is closed with concrete to complete the drainage and leak plugging work of the sump.

[0023] In this embodiment, the distance between the side wall of the bottom plate 1 and the well wall of the sump is 0.8 - 3 cm. Preferably, the distance between the side wall of the bottom plate 1 and the side wall of the sump is 1 cm. There is a certain distance between the side wall of the bottom plate 1 and the sump, which is convenient for grouting materials such as propylene hydrochloric acid to penetrate from the gap to the lower part of the bottom plate 1 to plug the sump and avoid repeated water leakage.

[0024] In this embodiment, the pressure relief valve group 3 includes at least one stainless steel ball valve, and the stainless steel ball valve is fixedly connected to the bottom plate 1. Threaded holes for cooperating with the pressure relief valve are provided on the bottom plate 1. The threaded holes on the bottom plate 1 can be adjusted according to the seepage volume of the sump. Preferably, four threaded holes are used. The stainless steel ball valve is threadedly connected to the threaded holes, which increases the connection stability and sealing performance, thereby realizing the negative pressure state during the drainage process and can also be used to check the drainage condition of the sump well.

[0025] In this embodiment, the bottom plate 1 is a steel plate. The thickness of the steel plate is 5 - 10 mm. Preferably, the steel plate is a 5-mm diamond plate, which is a commonly used steel plate in construction and has good structural stability and is not easily corroded after the later concrete pouring.

[0026] Specifically, four pressure relief valves are provided on the steel plate of this device. After fixing the device, the pressure relief valves are opened to pump out the accumulated water in the structure. After the pumping is completed, all valves are closed for structural leakage treatment. This can effectively solve problems such as poor forming quality of the plugging material and incomplete plugging during underwater operations. At the same time, after the plugging is completed, the valves can be opened. If there is still leakage at the bottom of the sump well, due to atmospheric pressure, the accumulated water will overflow through the valves, so as to check whether the leakage plugging is successful.

[0027] The structure and process of the basement sump well plugging device: The main skeleton of the dense pipeline positioning device is made of 5-mm thick steel plates. The steel plates are welded flush with each other. Four small square steel plates are additionally welded inside the steel plates and holes are opened to facilitate the subsequent hoisting of the device. Four switchable pressure relief valves are provided on the steel plate base and are mechanically threadedly connected to the steel plate to form the dense pipeline positioning device.

[0028] As Figure 2 shown in Embodiment 2, a basement sump well plugging device, side plates 2 are provided on all four sides of the bottom plate 1, and the four side plates 2 are connected into a frame structure. The four side plates 2 are connected end to end to form a frame structure, and the lower part of the frame structure is welded to the bottom plate 1 to form an integral structure, and it is a sealed weld. The rectangular structure further restricts the offset when the bottom plate 1 is lowered, ensuring that the bottom plate 1 can be placed into the sump well. At the same time, the base plate cooperates with the bottom plate 1 to form a plugging device, and the plugging effect is better.

[0029] In this embodiment, the suspension connecting piece includes a reinforcing rib plate 4 that cooperates with the side plate 2, and a suspension hole 5 is provided on the reinforcing rib plate 4. The reinforcing rib plate 4 is a stainless steel rib plate. One side of the stainless steel rib plate is welded to the side plate 2, and the lower part of the stainless steel rib plate is welded to the bottom plate 1. The reinforcing rib plate 4 is a rectangular rib plate, and the rectangular rib plate is connected to the middle of the side plate 2. The reinforcing rib plate 4 enhances the connection between the bottom plate 1 and the side plate 2, ensures the connection stability between the bottom plate 1 and the side plate 2, and at the same time realizes the support and plugging of the side wall of the sump well when the side plate 2 assists in connecting the bottom plate 1.

[0030] Working principle and application of this device: This device is applicable to the grouting plugging project for the leakage of the sump in the basement. The device can be made according to the patent information. During construction, first fix the device with a rope and lower it to the bottom of the sump. Then open the four valves to pump water. After the accumulated water is basically pumped out, close the remaining three valves in sequence and continue to pump out the remaining accumulated water until there is no accumulated water in the sump, and then close the pressure relief valve for leakage treatment. After the plugging is completed, the valve can be opened to check whether there is still leakage in the sump.

[0031] All other structures are the same as those in Embodiment 1.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
