浅谈仪征套闸除险加固工程交通桥脚手架支撑体系

Discussion on traffic bridge scaffold support system in Yizheng simple lock risk removal reinforcement project

目前,全国中小水利项目中的泵站、节制闸、船闸相比交通、铁路项目中的交通桥跨数较少且跨径较短,如若采用预制后架设,安全和资金上面投入的代价相比较大。本文结合仪征套闸除险加固工程这一实例,就套闸上闸首交通桥的实际情况,结合一系列理论验算依据,对其上闸首启闭机工作桥成功地进行了现浇,希望可以为中小型水利项目类似工程施工提供借鉴和参考。

At present, pumping station, check gate and lock of national small and medium - sized water conservancy projects have less spans and shorter span diameter compared with traffic bridges in transportation and railway projects. If they are erected after prefabrication, price of investing in safety and fund is higher. In the paper, the example of Yizheng suite lock risk elimination and reinforcement project as well as actual condition of traffic bridge on the head of suite lock are adopted. A series of theoretical calculation basis is combined for the the successful cast-in-situ of hoist working bridge on the gate head. It is expected that it can provide reference for similar constructions in small and medium-sized water conservancy projects.
