Abstract

The present application relates to a floating erection method of a bridge, comprising the following steps: setting an installation platform next to the abutment on one side of the bank; assembling a rotating device on the abutment; assembling a beam body on the installation platform , and connect one end of the beam body with the rotating device; connect the tugboat with the beam body, and drive the beam body to rotate around the abutment to a set position through the tugboat; drop the beam. This method assembles the beam body on the installation platform without setting up temporary structures such as guide beams and brackets beside the pier, which simplifies the construction steps; the tugboat supports one end of the beam body by using the buoyancy of the water, and the other end passes through the rotation of the bank. The device is supported to form a force-bearing structure in a simply supported state. When the tugboat is driving the beam body to rotate, the beam body is in a simply supported equilibrium state, which is easy to control and is not prone to overturning, which improves safety; The addition of permanent structures such as the prestressed structure of the cap and the rotating structure of the pier column reduces the difficulty of construction.

Description

technical field [0001] The present application relates to the technical field of bridge construction, in particular to a floating erection method of a bridge. Background technique [0002] At present, in bridge construction, common construction methods for wading bridges such as crossing rivers and lakes include support method, cantilever method, jacking method, etc.; support method requires a large number of temporary piers in the water; cantilever method requires large lifting equipment Temporary facilities such as pylons, buckle towers, and weights; the jacking method requires setting up guide beams, brackets next to the piers, and jacking systems. The above methods require more temporary facilities and more mechanical equipment during erection construction, which makes the construction operation cumbersome. , increasing the construction cost and construction time, and some methods affect the navigation of ships for a long time. [0003] In some related technologies, the...
