Abstract

The invention discloses a bridge rotation constructing process. A rotation system which is easy and convenient to manufacture, install and debug, and is safe, reliable and universal is researched. The rotation system mainly comprises a rotating hinge and a traction system. The process comprises the following steps of: realizing the bridge rotation firstly; and unloading the rotor system by using a hydraulic synchronous jacking technique, so that cyclic utilization of the rotation system is realized. The invention further discloses a rotation system, which comprises an upper rotating disk, a lower rotating disk, a jacking system, a horizontal fastening mechanism and a traction device, wherein the upper rotating disk and the lower rotating disk are rotationally connected relatively; the traction device is fixedly arranged on the lower rotating disk, and is used for driving the upper rotating disk to rotate; the horizontal fastening mechanism is connected with the lower rotating disk; and the jacking system is independently arranged on or arranged on the lower rotating disk. The rotation system has the advantages that the rotation system can be recycled after construction, so that the construction cost is lowered; and the rotation system is simple in structure, and can be recycled, so that equipment and construction costs of a rotation process are lowered.

Description

technical field [0001] The invention belongs to the technical field of bridge swivel construction, and in particular relates to a bridge swivel construction technology and a swivel system. Background technique [0002] Since the first Suining Jianjian Bridge built in 1977 with swivel construction, nearly 200 bridges have been built using the swivel construction method across the country. The swivel construction has developed from mountainous areas to plains; the swivel weight has increased from 1,000 tons to 10,000 tons; , and achieved better technical and economic benefits. [0003] Because the swivel construction has great advantages such as not affecting the operation of existing lines, navigation under the bridge, and driving, it has been widely used in the construction of bridges across deep valleys, rivers, and existing lines. With the implementation of the "National Railway's sixth major speed increase", China has entered the "High-speed Railway Era" during the "Ele...
