广州东圃特大桥梁体施工技术
|
摘要
东圃特大桥是广州市外环线高速公路上的一座特大型重点桥梁。大桥全长1093.5米，为双向六车道单层桥，左右线分离式结构。该桥基础为φ1.5米、φ2.0米挖孔桩，上部结构为连续刚构，桥墩采用双薄壁墩，边墩采用柱式墩。该桥施工特点是深水基础、跨径大。本文全面总结了东圃特大桥梁体施工技术；详细叙述了挂篮的选型、设计和计算，以及挂篮施工工艺、梁体施工等一系列施工技术与成果。重点介绍了斜拉式挂篮的结构形式与特点、水平分力的解决方式以及当斜拉带水平倾角过小、造成水平分力过大时采用垂直式挂篮施工梁体的新技术，对同类型桥梁施工具有参考价值。
Dongpu Extra-large Bridge is a key, extra-large bridge on Guangzhou Outer Ring Expressway with the total length of 1093.5m. It is dual-direction, six-lane, single-deck bridge with the separate structure of left and right line. The foundation of the bridge is 1.5m, 2.0m bored pile, the superstructure is continuous rigid structure, piers are dual-thin wall pier, side piers are column type pier. The bridge is deep water foundation with large span. This article sums up the construction technology of beam body of Dongpu extra-large bridge, make detailed description for construction technology and results of hanging basket selecting, design, calculating, and hanging basket workmanship, beam body construction. The key points it described are the type and characteristics of structure of stayed-cable hanging basket structure, solving way of level component and the new technology of adopting vertical hanging basket beam body to solve the problems of too small dip angle of stay-cable belt which will result in too muc
h level component. It has reference value for same kind of bridge construction.
