Synchronous displacement construction method for power transmission angle steel tower

Abstract

The invention discloses a synchronous displacement construction method for a power transmission angle steel tower. The synchronous displacement construction method comprises the following steps that S1, a connecting beam and a new base are poured; s2, tower legs of the angle steel tower are integrally fixed, and an angle steel tower body is reinforced; s3, a stay wire system, a jacking system, a traction system, a braking system and a sliding system are installed; and S4, the angle steel tower is moved and fixed to the new base, and movement of the angle steel tower is completed. According to the method, the processes of dismantling and assembling the power transmission angle steel tower can be omitted, the working intensity of workers is reduced, the high-altitude operation time is shortened, the personal safety of the workers is guaranteed, the construction efficiency is improved, and the purpose of recycling resources is achieved.

Description

technical field [0001] The invention belongs to the technical field of steel tower movement, and particularly relates to a synchronous displacement construction method for a power transmission angle steel tower. Background technique [0002] With the continuous development of the power grid, the transformation of service transmission lines is extremely common. Due to the constraints of line access, terrain and other factors, some towers in the transformation section of the line are very close to the original line. In order to achieve "carbon peaking and carbon neutrality" resources Reuse, use the original line tower to realize the laying of the new line. Due to the terrain, the mobile crane cannot pass through, and the overall hoisting of the original tower cannot be realized. Only the traditional method of first dismantling and then grouping can be used, that is, the original line tower is removed from the top. They were dismantled piece by piece, transported to the new tow...

Problems solved by technology

[0002] With the continuous development of the power grid, the transformation of transmission lines in service is very common. Due to the constraints of line passages, terrain and other factors, some towers in the line reconstruction section are very close to the original line. In order to achieve "carbon peak, carbon neutral" resources Reuse, use the original line tower to realize the laying of the new line. Due to the terrain, the mobile crane cannot pass through, and the overall hoisting of the original iron tower cannot be realized. The traditional method of first dismantling and then reassembling can only be used, that is, the original line iron tower is removed from the top first. Dismantled one by one, transported to the new tower foundation and assembled manually one by one again, but because there are thousands of galvanized angle steels of different specifications, tens of thousands of bolts of different specifications, anti-loosening buckles, and bolts on the transmission angle steel tower. The anti-theft cap requires a lot of work to disassemble and assemble. In addition, the iron tower of the transmission line is exposed to the outside all the year round, so there are inevitably corrosion and other phenomena. The bolt disassembly process will inevitably cause damage to the thread, which will seriously affect the reassembly.
