Transmission tower foundation treatment method for power plant

Abstract

The invention relates to a transmission tower foundation treatment method for a power plant. A transmission tower foundation treatment device for the power plant is adopted and comprises a foundationpit and a die sleeve mechanism. The foundation pit is formed in the existing ground, and the die sleeve mechanism is arranged in the foundation pit in a sliding fit mode. The design concept of a variable-size structure is adopted for transmission tower foundation treatment of the power plant, and the arranged die sleeve mechanism can change the relative adaptive inner diameter size according to concrete columns of different sizes, so that the overall application rate of the device is increased. In addition, the die sleeve mechanism integrally has detachability and can be repeatedly used so asto meet the requirements of assembly and disassembly at any time, and therefore the working cost can be reduced on the premise that the working efficiency is not affected.

Description

technical field [0001] The invention relates to the technical field of installation of power transmission towers, in particular to a foundation treatment method for power transmission towers in power plants. Background technique [0002] Overhead transmission lines are mainly composed of tower foundations, towers, conductors, lightning protection wires, insulators, pull wires, fittings, and grounding devices. The tower foundation is used to fix the tower on the ground to stabilize the tower and ensure that the tower does not tilt or collapse. , sinking and uplifting facilities, which have the function of fixing the tower. The foundation construction of the tower mainly includes the basic procedures such as the ratio of concrete raw materials, foundation pit excavation, support installation, concrete pouring, backfilling construction, etc., and is classified according to the construction characteristics. Tower foundations can be divided into prefabricated foundations, cast-in...

Problems solved by technology

[0003] 1. Most of the concrete pouring molds used are non-reusable disposable molds, which further increase the construction cost and make the construction steps cumbersome. When using detachable pouring molds, the mold disassembly parts Without additional sealing, the gaps between the concrete will easily increase the probability of concrete spillage;

[0004] 2. During the process of placing the casting mold in the foundation pit, there is a deviation in the docking between the mold and the center of the foundation pit, which leads to the deviation of the installation position of the subsequent pole, and at the same time, the movement such as vibration and the deviation of the mold accompanying the concrete pouring process Scratches and other phenomena that are prone to occur during the placement process lead to deformation phenomena such as collapse on the inner wall of the foundation pit
