TECHNICAL FIELD

[0001] The utility model relates to the technical field of precipitation well plugging, in particular to a precipitation well plugging device. BACKGROUND

[0002] In the civil engineering construction industry, laying a precipitation well in a foundation pit is the most common precipitation method. After the main body of the precipitation well is completed and meets the anti-floating requirements, the precipitation well often needs to be closed by a plugging device.

[0003] At present, the Chinese patent with the application number CN202223430903.2 on the market discloses a precipitation well plugging device, which comprises a bottom plate, a cylinder, and a plug. The cylinder is vertically arranged on the upper end face of the bottom plate. The bottom plate is used for welding with the inner wall of the precipitation pipe. The bottom plate is provided with a through hole in communication with the cylinder. The plug is detachably installed on the upper end of the cylinder. The device further comprises a water stop plate welded on the upper end of the precipitation pipe.

[0004] In the above-mentioned prior art, the bottom plate is welded with the inner wall of the precipitation pipe (precipitation well). However, due to the installation gap between the bottom plate and the well wall, one person usually needs to hold the cylinder on the bottom plate during welding, which wastes manpower. Moreover, when the bottom plate is placed into the precipitation well without welding, the bottom plate and the cylinder will fall into the precipitation well if the person holding the cylinder slips, which is inconvenient to use. Therefore, the applicant has developed a new technical solution in the actual production process to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0005] In view of the above technical deficiencies, the purpose of the utility model is to provide a precipitation well plugging device, which has the advantage of saving manpower without manually holding the cylinder on the bottom plate.

The cylinder is coaxially communicated with the bottom plate. The cylinder is located inside the precipitation well and below the rectangular frame. The rectangular frame is provided with a clamping piece for clamping the cylinder.

[0008] Through the above technical solutions, when in use, the cylinder is clamped by the clamping piece on the rectangular frame, and then the bottom plate on the cylinder is aligned with the well mouth of the precipitation well and inserted until the bottom end of the rectangular frame contacts the top end of the well mouth of the precipitation well. Then the bottom plate is welded on the inner wall of the precipitation well. Through the above process, the cylinder does not need to be held during welding, which saves manpower. Moreover, when the bottom plate is placed into the precipitation well without welding, the cylinder is clamped by the clamping piece on the rectangular frame, which reduces the occurrence of the situation that the bottom plate and the cylinder fall into the precipitation well.

[0009] Preferably, the clamping piece comprises two sliders horizontally slidingly connected in the rectangular frame along the length direction of the rectangular frame, and the bottom end of each of the two sliders is vertically provided with a clamping plate, and each of the two clamping plates is provided below the side close to each other with a clamping block, and the side close to each other of each of the two clamping blocks is an arc surface abutting against the outer wall of the cylinder, and the rectangular frame is provided with a pushing piece for simultaneously pushing the two sliders away from or close to each other.

[0010] Preferably, the pushing piece comprises two lead screws coaxially fixedly connected, and the two lead screws are arranged along the length direction of the rectangular frame and are rotatably connected to the left and right sides of the rectangular frame, respectively, one end of each of the two lead screws penetrates through the two sliders and is threadedly connected with the two sliders, and the rectangular frame is provided with a rotating ring for driving the lead screws to rotate, and the threads on the two lead screws are opposite in rotation direction.

[0011] Preferably, the arc surface of each of the two clamping blocks is provided with an anti-skid pad between the cylinder and the clamping block.

[0012] Preferably, the clamping block is mounted on the clamping plate by bolts.

[0013] Preferably, the bottom end of the rectangular frame is provided with a rubber layer in contact with the top end of the wellhead of the precipitation well.

[0014] The beneficial effects of the utility model lie in that: when in use, the cylinder is clamped by the clamping piece on the rectangular frame, and then the bottom plate on the cylinder is aligned with the wellhead of the precipitation well and inserted, until the bottom end of the rectangular frame is in contact with the top end of the wellhead of the precipitation well, and then the bottom plate is welded on the inner wall of the precipitation well, through the above process, the cylinder does not need to be held by hand during welding, manpower is saved, and when the bottom plate is put into the precipitation well and has not been welded, the clamping piece on the rectangular frame clamps the cylinder, so that the situation that the bottom plate and the cylinder fall into the precipitation well is reduced.
