某大型转体桥转体系统关键施工技术探讨

Study on the Construction of Large-Scale Revolving Bridge Revolving System

某大型市政桥梁为双转体现浇梁,转体施工是该项目的重要环节。对此阐述该项目上下球铰、滑道、撑脚、底膜等的安装,并进行转体系统检测和转动实验,使施工最终达到设计要求,打好项目施工基础,同时为类似工程提供参考。

A large-scale municipal bridge is a double revolving body cast-in-place beam,revolving construction is an important link of the project.This paper explores the installation of the lower ball hinge and slide,the installation of the upper ball hinge and supporting foot,pouring the turntable concrete,and testing the rotating body system and rotating experiments.The design requirements for the construction of double-rotating cast-in-place beam is realized and reference to similar projects can be derived.
