厂内预制水工机架桥在郯城县土山拦河闸除险加固工程中的应用
|
摘要
在大型水闸工程中,为了加快施工进度、降低工程成本、减小施工期的安全隐患,多采用预制机架桥,常规结构形式有T型和π型。本文以水工机架桥厂内预制在郯城县土山拦河闸出险加固工程中的应用为例,重点阐述了施工难度大、工序多、质量要求高的大型π型机架桥预制施工工艺,该工艺对T型梁施工也有着较高的借鉴价值。
In the large sluice project,prefabricated machine bridge is mostly adopted in order to speed up the construction schedule,reduce the project cost,and reduce the safety hazard during the construction period. The conventional structures include T type and π type. In the paper, the application of hydraulic machine bridge factory prefabrication in Tancheng Tushan Penstock risk removal and reinfocement project is adopted as an example. The large π machine bridge prefabrication construction process with high construction difficulty,excessive construction procedures and high quality requirements is mainly described,and the process has higher reference value to T-shaped bridge construction.
