浅谈挂篮施工0#块临时锚固和支架体系的优化

Elementary Discussion on Optimization of 0# Provisional Anchorage and Bracket System Constructed by Traveling Form

以海西高速公路网东山联络线A标段的东山特大桥为背景,对东山特大桥主桥0#块现浇支架、临时锚固体系进行了方案优化及对比。优化后的方案采用简单的混凝土立柱代替传统的钢管混凝土支撑体系,提高了施工安全性加快了施工进度同时又降低了施工成本。

Taking Dongshan Bridge in Bid A of Dongshan Liaison Line in Haixi Expressway as thebackground, the article introduces the scheme optimization and comparison of the main bridge 0# cast-in-situ bracket and provisional anchorage system of Dongshan Bridge. The optimized scheme uses the simple concrete column instead of the conventional concrete filled steel tube support system, which improves the construction safety, speeds up the construction schedule and also reduces the construction cost.
