Description

Technical Field

[0001] The utility model belongs to the technical field of dewatering well installation, in particular to an auxiliary platform for a foundation pit dewatering well. Background Art

[0002] During the construction of rail transit, such as the construction of underground stations, deep foundation pits are often excavated. During the construction process, an underground tunnel drainage system is used to guide the water inside the deep foundation pit along the ditch into precipitation wells at certain intervals, and then flow into the water tank through the underground tunnel connected to the precipitation well. The water is then pumped to the ground through a special drainage well or directly flows out of the ground through the drainage tunnel. After the excavation of the deep foundation pit is completed, a precipitation well is often installed inside the deep foundation pit.

[0003] Current precipitation wells are generally formed by splicing multiple well pipes. When splicing the well pipes, the well pipes are placed in the pre-dug wellhead in sequence. During the placement process of the above method, the well pipes are often not fully spliced ​​(i.e., a certain pipe section is tilted), which affects the quality of the precipitation well.

[0004] In view of this, the applicant designed an auxiliary platform for foundation pit dewatering wells. Utility Model Content

[0006] The technical solution adopted by the present utility model is as follows: an auxiliary platform for a foundation pit dewatering well, including an auxiliary platform installed on the periphery of the dewatering well mouth, the auxiliary platform including two support pipes and connecting rods, the two support pipes are arranged symmetrically along the well mouth of the dewatering well, through holes are opened on both sides of the support pipes to meet the longitudinal passage of the connecting rods, and the support pipes and the connecting rods together form a pipe placement space.

[0007] In a preferred embodiment, a plurality of annular grooves for winding steel wire ropes are longitudinally provided in the middle portion of the support tube.

[0008] In a preferred embodiment, the through hole is a polygonal structure, and the connecting rod is the same as the through hole.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0012] 1. In the present invention, the auxiliary platform can be made of pipes and steel bars discarded at the construction site, which can save the manufacturing cost of the auxiliary platform and realize the utilization of waste resources.

[0013] 2. In the present invention, when installing well pipes, the auxiliary platform can be used to limit the well pipe splicing position to above the wellhead, which facilitates the splicing of well pipes while ensuring the splicing accuracy between well pipes;

[0014] 3. In the present invention, the auxiliary platform is composed of a support tube and a connecting rod. After use, the support tube and the connecting rod can be disassembled and stored, making it more convenient to carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Reference Figure 1-3 , an auxiliary platform for a foundation pit dewatering well, including an auxiliary platform installed on the periphery of the dewatering well mouth, the auxiliary platform includes two support pipes 1 and connecting rods 3, the two support pipes 1 are arranged symmetrically along the transverse direction of the dewatering well mouth, and through holes 13 are opened on both sides of the support pipe 1 to meet the longitudinal passage of the connecting rod 3. The support pipe 1 and the connecting rod 3 are surrounded by a pipe-releasing space 2. When installing the well pipe, the auxiliary platform can be used to limit the splicing part of the well pipe to the top of the well mouth, which is convenient for splicing between the well pipes while ensuring the splicing accuracy between the well pipes. The support pipe 1 and the connecting rod 3 are surrounded by a square structure to ensure the overall stability of the auxiliary platform.

[0021] In addition, the auxiliary platform is composed of a support tube 1 and a connecting rod 3. After use, the support tube 1 and the connecting rod 3 can be disassembled and stored, making it more convenient to carry.

[0022] The specific installation process of the well pipe is as follows: Figure 3 As shown, when installing the well pipe, build the auxiliary platform and install it on the periphery of the precipitation well mouth, then wrap both sides of the wire rope around the support pipe 1 (leave room at both ends of the wire rope for lowering), then place the bottom well pipe (a gap can be reserved for placing the wire rope) on top of the wire rope between the two support pipes 1 and then put it into the well mouth. The two ends of the wire rope can be pressed down by feet or other objects that can be pressed down, then align the upper spliced ​​well pipe with the bottom well pipe and splice them together, then slowly lower the wire rope until the mouth of the upper well pipe reaches above the well mouth, and then repeat the above steps. After the well pipe is installed, pull out the wire rope from one side.

[0023] Furthermore, a plurality of annular grooves 11 for winding the steel wire rope are provided in the longitudinal direction in the middle of the support tube 1. The annular grooves 11 can help define the position of the steel wire rope and prevent the steel wire rope from being deviated.

[0024] Furthermore, the through hole 13 is a polygonal structure, and the connecting rod 3 is the same as the through hole 13. The above design can prevent the connecting rod 3 from self-rotating.

[0025] Furthermore, the support tube 1 is made of hollow stainless steel, and the connecting rod 3 is made of solid stainless steel. The auxiliary platform as a whole can be spliced ​​together with discarded pipes and steel bars on the construction site, which can save the manufacturing cost of the auxiliary platform and realize the utilization of waste resources.

[0026] Furthermore, plugs 12 are symmetrically welded at both ends of the bottom of the support pipe 1 along the length direction. When installing the support pipe 1, the plugs 12 can be inserted into the soil to prevent the support pipe 1 from rolling, thereby ensuring the stability of the auxiliary platform after installation.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
