Large Bridge Swivel Construction Technology
-
摘要: 桥梁转体施工一般在不能通过直接架设模版浇筑混凝土的情况下使用。先将桥梁在易于施工的区域预制在可旋转支座上,再利用一些机具设备将该桥体转到主桥位轴线位置合拢。不同情况和形状的桥体,其施工方法各有特点。本文针对转体重量大、转动角度大、梁体较长的转体桥施工进行了阐述,以期对类似桥梁施工提供参考。Abstract: Bridge swivel construction technology is employed in the case that concreting cannot be done directly by erecting formwork. Firstly,the bridge shall be prefabricated in an area which is suitable for construction, and then,by using some machines and equipment,the bridge body on the rotatable bearing shall be turned to the axis position of the bridge so as to realize the closure of the bridge.Diff erent conditions and shapes of bridge bodies have their own characteristics in construction methods.This paper introduced the construction of the bridge body with large swivel weight,large swivel angle and long beam body, which can provide reference for similar bridge construction.
