[0020] In order to enable those skilled in the art to better understand the content of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.

[0021] Based on the background technology, in order to prevent the pumping pipe from falling off during the pumping process and reduce the incidence of accidents of falling into the well, the present application provides a pumping pipe fixing tool for a dewatering well, including a sleeve 1 sleeved on the wellhead of the dewatering well and a bottom plate 2 connected to the lower end of the sleeve 1, the bottom plate 2 is provided with side plates 3 surrounding the sleeve 1, the outer walls on both sides of the sleeve 1 are provided with connecting members 4 extending vertically, and a cavity 5 is formed between the connecting members 4 and the outer wall of the sleeve 1, a screw 6 is provided in the cavity 5, and the screw 6 is provided with a first nut 7 at the bottom and a second nut 8 at the top, a semicircular cover plate 9 is detachably connected between the first nut 7 and the second nut 8 so that the bottom edges of the two groups of the semicircular cover plates 9 are relative to each other and cover the wellhead of the dewatering well, the semicircular cover plate 9 is provided with an opening 10 at the center of the bottom edge for the pumping pipe to pass through, and clamps 11 are respectively provided on both sides of the opening 10.

[0022] In specific implementation, the diameter of the sleeve 1 should be larger than the wellhead of the drainage well. The sleeve 1 is connected to the bottom plate 2 through the top and bottom. The edge of the bottom plate 2 is enclosed by the side plate 3. The bottom plate 2 can be covered with soil or concrete and other materials to fix the fixing tools. The outer wall of the sleeve 1 is provided with a connector 4, and a cavity 5 with an upper end opening is formed between the connector 4 and the outer wall. The cavity 5 should have a space that allows tools or human hands to operate. A screw 6 is vertically arranged in the cavity 5. The screw 6 is only welded to the bottom plate 2, and is not connected to the inner wall of the connector 4 and the outer wall of the sleeve 1. The screw 6 and the inner wall of the connector 4 and the outer wall of the sleeve 1 should have a certain distance to allow the bolt to move. The upper end of the screw 6 should be higher than the upper opening of the sleeve 1 to adjust the height of the semicircular cover plate 9.

[0023] The outer wall of the sleeve 1 is provided with screws 6 on both sides, so that the wellhead of the precipitation well is covered by two semicircular cover plates 9, and the wellhead of the precipitation well is detachably connected to the first bolt and the second bolt. When in use, after the sleeve 1 is inserted into the wellhead of the precipitation well, the first bolt on one side is adjusted so that the first bolt is flush with the wellhead of the precipitation well, and then the semicircular cover plate 9 is installed. Before the semicircular cover plate 9 is installed, the pumping pipe, wires and water pump need to be placed in the precipitation well. When the semicircular cover plate 9 on one side is installed, the position of the pumping pipe and the wire is adjusted so that each of them is stuck in the corresponding hole, and then the first bolt on the other side is adjusted and the semicircular cover plate 9 is installed. After the semicircular cover plates 9 on both sides are installed, the second bolt is installed and fixed. The fixing of the pumping pipe can be achieved by setting a clamp 11, which is respectively set on the two semicircular cover plates and fastened by bolts.

[0024] The cover plate is directly or indirectly connected to the first bolt and the second bolt by clamping.

[0025] In one implementation of this embodiment, a hook 12 is provided on the edge of the semicircular cover plate 9, and the hook 12 is located between the first nut 7 and the second nut 8. The hook 12 is connected to the semicircular cover plate and then hung on the screw rod 6, and the second nut 8 is installed to achieve fastening.

[0026] In one implementation of this embodiment, the radius of the semicircular cover plate can be processed to be slightly larger than the size of the wellhead of the precipitation well, so that the first nut 7 and the second nut 8 can clamp the edge of the semicircular cover plate 9 to achieve fixation.

[0027] In one implementation of this embodiment, the connector 4 is an angle steel, and the angle steel is welded to the outer wall of the sleeve 1 along two vertical sides. Angle steel is a common material in the construction process, is easy to obtain, and can form a cavity 5.

[0028] In one implementation of this embodiment, the bottom edge of the semicircular cover plate 9 is provided with a wire hole 13 for the wire to pass through, and the wire hole 13 is arranged on both sides of the clamp 11. The wire hole 13 is used to pass the wires of the water pump, and the power supply box 14 is arranged on the outer wall of the side plate 3 to facilitate the operation of the water pump, reduce the length of the wire, and reduce the risk of leakage.

[0029] The above description is only the basic principle and preferred embodiments of the present invention. Improvements and substitutions made by those skilled in the art based on the present invention belong to the protection scope of the present invention.
