Description

Technical Field

[0001] The utility model belongs to the technical field of dewatering wells, in particular to a water-stopping device for a dewatering well. Background Art

[0002] At present, it is necessary to excavate drainage wells during the construction process of foundation pits. The drainage wells are used to lower the groundwater level and prevent water inrush during the excavation of the foundation pit. The drainage wells are generally drilled out with drilling tools, and then the well pipes are installed inside the well holes. A water pump is placed at the bottom of the well to continuously pump water. In order to prevent construction waste and debris from entering the well, a drainage well water-stopping device is generally installed in the well to prevent debris from clogging the drainage well.

[0003] A Chinese patent application with publication number CN218540741U discloses a drainage well water-stopping device, including an inflatable capsule for being placed on the water surface inside the well pipe to support fallen foreign objects. The inflatable capsule is formed with a water supply pump pipeline and a through hole for the water suction pipe to extend to the outside of the well pipe. The outer edge of the inflatable capsule is circular, and the side wall of the outer edge of the inflatable capsule is tightly abutted against the inner wall of the well pipe. The application has the effect of supporting the foreign objects when foreign objects fall into the well pipe, reducing the probability of foreign objects accumulating in the well pipe and clogging the well pipe, or even causing the well pipe to be scrapped. Through the arrangement of the inflatable capsule, excavation machinery can be used for excavation in a certain area around the drainage well, thereby improving the construction efficiency of earth excavation.

[0004] Although this patent uses an inflatable capsule to seal the wellhead to prevent external debris from entering the well, it requires the air pump to be continuously turned on to keep the inflatable capsule in an inflated state. Due to the complex construction site environment, once the air pump cable breaks accidentally during construction, the inflatable capsule will shrink and be unable to seal the wellhead, causing construction waste and debris to fall directly into the well, affecting the normal operation of the drainage well and being unfavorable for people's use. For this reason, we provide a drainage well water-stopping device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a drainage well water-stopping device, which solves the problem in the prior art that the drainage well water-stopping device requires the air pump to be continuously turned on, and the inflatable capsule cannot seal the drainage well after the air pump is powered off, through the coordinated arrangement of a fixing component and a shielding component.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a water-stopping device for a drainage well, comprising a cover plate, a fixing assembly and a shielding assembly, wherein a conveying opening is provided on the front side of the top of the cover plate;

After the trapezoidal blocks 303 are squeezed, they drive the installation frame 304 and the friction block 305 to move. The friction block 305 moves to fit the well wall, and the cover plate 1 is positioned and fixed by friction. At the same time, the friction block 305 drives the installation rod 5 and the clamping plate 6 to move. The clamping plate 6 moves to clamp the edge of the wellhead, and the clamping plate 6 is clamped.
