Rotating body constructing method and rotating system

Abstract

The invention discloses a rotating body constructing method and a rotating system, and belongs to the technical field of bridge construction. The method includes the steps of removing a fixing structure between an upper bearing table and a lower bearing table; making a to-be-rotated body rotate around a rotating center by a first preset angle, wherein the upper bearing table is arranged on the to-be-rotated body and rotate along with the to-be-rotated body; arranging a limiting beam, making the limiting beam abut against a supporting leg so as to limit the rotating angle of the to-be-rotated body, wherein the supporting leg is arranged on the upper bearing table; making the upper bearing table sealed and hinged to the lower bearing table so that the upper bearing table and the lower bearing table can be fixedly connected. The rotating system conducts rotation operations on the to-be-rotated body through the rotating body constructing method. By means of the rotating body constructing method, it can be avoided that the to-be-rotated body continues to rotate after arriving at a target position, and therefore the rotating accuracy of the rotating body constructing method is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a swivel construction method and a swivel system. Background technique [0002] Bridge swivel construction is widely used in three-dimensional traffic engineering. The process includes: constructing two half-width bridges on both sides of the existing line such as railway or expressway, each half-width bridge is supported on a pier column, and the construction is balanced on both sides of the pier column For the beam body, after the construction of the beam body is completed, the two half-width bridges are rotated by means of rotation to make the axes of the two half-width bridges coincide, and finally the gap between the two half-width bridges is poured to form a whole bridge. [0003] In the prior art, after the bridge completes the rotation angle, the bridge and the rotation system are directly poured, so that the bridge and the rotation system are fixedly connecte...

AI Technical Summary

Problems solved by technology

However, when the bridge rotation is completed and the rotating equipment is shut down and no longer provides the bridge with rotational torque, the bridge will still continue to rotate at a certain angle along the original rotation direction under the action of inertial force. In this way, the two and a half bridges Axes end up misaligned and at an angle, failing to form an overall bridge
