Construction method for foundation of electric power iron tower of power transmission line

Abstract

The invention provides a construction method for a foundation of an electric power iron tower of a power transmission line. The construction method comprises a joint control mechanism, a main body mechanism and a platform straight plate, wherein the platform straight plate is arranged on the main body mechanism in a sliding fit mode, and the joint control mechanism is installed on the end surface of the middle of the platform straight plate. According to the construction method, the problems that in the existing foundation pouring construction process, a fixing mode of foundation bolts is usually clamping and fixing by adopting a single piece of channel steel or a batten, the foundation bolts cannot be effectively fixed in the mode, so that the perpendicularity of the foundation bolts exceeds an error allowable range, the exposure height of the foundation bolts is difficult to synchronously control, the moving distance between the centers of the foundation bolts and the center of the foundation is difficult to synchronously control, long-time adjustment and fixing are needed, so that the construction efficiency of the foundation is low, the construction quality of the iron tower foundation is difficult to guarantee, and the stability of the foundation bolts applied to a connecting foundation and the power transmission line iron tower is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of electric power tower foundation construction and construction, in particular to a construction method for power transmission line power tower foundation construction. Background technique [0002] The transmission line tower is a tower-shaped building for power transmission. The transmission line tower is a tower structure used to support and overhead wires, lightning conductors and other accessories. According to its shape, it is generally divided into: wine glass type, cat head type, and upper font There are five types, dry type and barrel type. According to the purpose, there are steel pipe towers, angle steel towers, straight towers, corner towers, transposition towers, terminal towers and spanning towers, among which steel pipe towers are more common. [0003] The foundation construction of the power tower is the most important part in the installation process of the steel pipe tower, because only ef...

AI Technical Summary

Problems solved by technology

[0004] Nowadays, in the process of foundation pouring construction, the fixing method of anchor bolts is usually clamped and fixed by single channel steel or wooden strips. This method cannot effectively fix the anchor bolts, causing the verticality of the anchor bolts to exceed the allowable range of error , and it is difficult to control the exposed height of the anchor bolts synchronously, and it is difficult to control the moving distance between the center of the anchor bolts and the center of the foundation synchronously. It takes a long time to adjust and fix, resulting in low efficiency of foundation construction, and it is difficult to ensure the quality of the tower foundation construction. Affect the stability of anchor bolts used in the connection foundation and transmission line iron tower; for this reason, the invention provides a kind of transmission line power iron tower foundation construction method
