Bridge rotation construction support and bridge construction method

Abstract

The invention provides a bridge rotation construction support, which is characterized by mainly comprising a pier body, a positioning steel spindle, concrete buttresses, a bearing platform, a jack reaction seat, an outer slide way, a turntable and steel tube concrete supporting legs, wherein the upper half part of the rotation construction support consists of the pier body, the turntable and the steel tube concrete supporting legs; the lower half part of the rotation construction support consists of the positioning steel spindle, the concrete buttresses, the bearing platform, the jack reaction seat and the outer slide way; and the upper half part and the lower half part can rotate by sliding. By the rotation construction support, an expensive bracket is not required to erected, installation and erection processes are reduced, high-altitude operation and water operation which are complicated and high in technicality are changed into shoreside land operation, a bridge is safely constructed and desirable in quality, traffic is not interfered, navigation is not interrupted, damage to environment is reduced, and construction cost and machine tool equipment are reduced in the construction process of a navigable river or a flyover with heavy traffic, and good technical, economic and social benefits are achieved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a method for adopting a swivel construction support and carrying out bridge construction. Background technique [0002] During the construction of roads and bridges, in order to ensure the traffic safety of the roads, railways, rivers and waterways crossed by the bridges, partial navigation measures must be taken. Blockage; or the use of line closure measures for roads or railways will not only affect normal traffic, but also affect the safety and progress of the project itself. In order to not only ensure the safety of engineering construction, but also minimize the impact on the smooth flow of waterways, shorten the time for sealing navigation and line closures, and reduce construction costs, bridge swivel technology has emerged as the times require. [0003] Most of the usual construction of highway and bridge swivel sliding bearings adopts separate concrete structure ...

AI Technical Summary

Problems solved by technology

[0003] Most of the usual construction of highway and bridge swivel sliding bearings use separately set concrete structure or steel structure components as the swivel grinding center. The structure is complex. After the swivel is completed, these components required for installation have to be dismantled

In this way, in addition to the original structural engineering, it not only increases the engineering cost, but also wastes a lot of engineering materials, and also prolongs the progress of the entire project, thus greatly reducing the construction efficiency of the project.
