Bridge and construction method thereof

Abstract

The invention relates to a bridge and the construction method. The bridge comprises bridge pier and beam body. Horizontal rotary device is set between bridge pier and beam body. The method comprises manufacturing bridge pier, setting horizontal rotary device at the top of said bridge pier and accomplishing the construction for rotating beam body on the horizontal rotary device. By the technology project mentioned above, under the condition of higher bridge pier or larger cubage, the construction difficulty of bridge is decreased greatly and stability and safety of bridge construction can bridge rotation are guaranteed.

Description

technical field [0001] The invention relates to a bridge technology, in particular to a rotatable bridge and a construction method thereof. Background technique [0002] During the bridge erection process, it may encounter roads, railways and other routes in operation. Therefore, in the process of bridge construction, it is necessary to solve how to complete the bridge erection without affecting the normal operation of roads and railways. [0003] At present, there is a kind of bridge, by installing a translation device between the bottom of the bridge pier and the ground at the initial stage of construction, so that the bridge pier and the girder body that needs to cross the route can be completed in advance in the area outside the route, and then the bridge pier is rotated by the translation device to drive The beam body rotates and crosses the route, so that the other end of the beam body reaches the rotating position on the opposite side of the route, such as a permanent...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the small diameter of the bridge pier, it is necessary to install a pressure dispersing device between the bridge pier and the rotating device to bear the load-bearing girder body, tower and other parts that need to be rotated, resulting in a complex bridge structure that is not conducive to construction;

[0006] 2. When the pier is high or the volume of the pier is large, the weight of the swivel body will increase greatly, resulting in increased difficulty of rotation, and when the pier is high, it will also lead to poor stability of the swivel body, and at the same time bring safety hazards to the operating routes
