Bridge pier swivel structure and construction method thereof

Abstract

The invention belongs to the field of bridge construction, and especially relates to a bridge pier swivel structure and a construction method thereof. A driving motor is fixedly connected to the innerwall of the top of a mounting chamber on a bridge base; an output shaft of the driving motor is fixedly connected with a rotating shaft; engaged bevel gears fixedly sleeve a driving shaft rotationally connected to the inner wall of one side of the mounting chamber and the bottom end of the rotating shaft; a rectangular plate is fixedly connected to the top of a movable plate in threaded connection with the driving shaft; a fixing shaft is rotationally connected to the inner wall of the bottom of the mounting chamber; a steel wire rope is wound on a winding roller fixedly arranged on the fixing shaft in a sleeving manner; one end of the steel wire rope is fixedly connected with one side of the rectangular plate; the top end of the fixing shaft penetrates through the inner wall of the top of the mounting chamber and is fixedly connected with a rotating disc; and the rotating disc is movably clamped with a pier. The problems that an existing bridge pier rotating body structure is not easy to rotate and unstable in rotation due to overlarge friction in the relative rotating process, the rotating body structure is not easy to detach, and later maintenance is inconvenient are solved.

Description

technical field [0001] The invention belongs to the field of bridge construction, and relates to a bridge pier swivel structure and a construction method thereof. Background technique [0002] Bridge swivel construction refers to a construction method in which the bridge structure is formed (cast or spliced) at a position other than the design axis, and then put in place by swivel. It converts operations over obstacles to operations onshore or near the surface. According to the rotation direction of the bridge structure, it can be divided into vertical rotation construction method, horizontal rotation construction method (referred to as vertical rotation method and rotation method) and a combination of horizontal rotation and vertical rotation method, among which the horizontal rotation method is the most widely used. . It is mainly used in situations where the canyon, river, railway, highway, etc. cannot be supported. [0003] The existing bridge pier swivel structure ha...

AI Technical Summary

Problems solved by technology

[0004] In view of this, in order to solve the problems of the existing bridge pier swivel structure, the friction in the process of relative rotation is too large, which makes it difficult to rotate, the rotation is unstable, and the swivel structure is not easy to dismantle and inconvenient for later maintenance. Propose a bridge pier swivel structure and its construction method
