Description
Technical Field
[0001] The utility model relates to the technical field related to pile segment welding, in particular to a verticality correction tool before pile segment welding. Background Art
[0002] Pile segment welding is to embed low-carbon steel plates on the sides and end faces of the four corners of the upper and lower pile segments. The surface should be kept clean. It is a method of connecting piles. It can connect the upper and lower groups of pile segments to make them longer, so as to carry out deeper underground work and enable the pile segments to enter the underground deeper. Pile segment welding is suitable for all kinds of soil layers, and is suitable for piles with high bearing capacity, large aspect ratio, dense pile foundation or piles that need to pass through a certain thickness of hard soil layer and difficult pile sinking. However, the existing pile segment welding basically only splices the pile segments of the upper and lower links, but the splicing requires the intervention of auxiliary tools to make the pile segments better docked. Therefore, a verticality correction tool before pile segment welding is particularly needed.
[0003] However, most of the existing verticality correction tools for pile segment welding use a crane to lift a pile segment and place it in contact with the pile segment at the lower end, then simply fix it with a tool, and then command the crane to move by eye to align the upper and lower pile segments, and then start welding directly. This may cause the upper and lower pile segments to be misaligned, resulting in the upper and lower pile segments not being vertical, so that the drilled holes are not vertical enough. Utility Model Content
[0004] The utility model aims to provide a verticality correction tool before welding a pile segment, so as to solve the problem of the verticality correction tool before welding a pile segment proposed in the above-mentioned background technology. Most of the verticality correction tools for welding pile segments use a crane to lift a section of the pile segment, so that it is placed in close contact with the pile segment at the lower end, and then simply fixed by a tool, and then the crane is directed to move by the naked eye to align the upper and lower pile segments, and then welding is started directly, which may cause the upper and lower pile segments to be uneven, resulting in the upper and lower pile segments not being vertical, so that the drilled holes are not vertical enough.
[0005] To achieve the above object, the utility model provides the following technical solution: a verticality correction tool before welding a pile segment, comprising a base, a bracket fixedly connected to one side surface of the base, a correction mechanism provided on one side surface of the bracket, and a clamping mechanism provided on one side surface of the base;
