Description

Technical Field

[0002] In recent years, the proportion of steel bridges in bridge construction has gradually increased. The steel towers used in bridges are gradually replacing the concrete structures to become the mainstream of bridge towers due to their advantages such as good flexibility, high processing accuracy, easy realization of factoryization, and rapid installation at the bridge site. At present, the steel tower is one of the widely used structural forms for the bridge tower piers of suspension bridges. Among them, the steel tower is usually manufactured in standardized segments in the factory. Due to requirements such as pre-deviation and design linearity of the steel tower, the requirements for installation accuracy are relatively high. At present, the more commonly used method is to adjust the angle and height of the steel tower segment to be installed through a lifting tool, and use temporary matching parts for docking and limiting, so that the position of the steel tower segment conforms to the design, and then temporarily fix it through pins or bolts. However, with the increase in the lifting height, due to the influence of temperature, wind force, etc. under high-altitude conditions, it is very difficult to achieve one-time lifting in place; at this time, it is necessary to take corresponding measures to accurately adjust the position of the steel tower segment to achieve the designed position linearity, and then carry out welding and bolting of the steel tower segment.
