旧桥改造施工过程中,伸缩缝的安装工艺一直是困扰施工人员的技术壁垒,表现在平稳度和牢固度达不到设计要求,并且伸缩缝的安装是拖延施工工期的的主要环节。通过实践,不但安装平稳度和牢固度达到了设计要求,而且施工工期得到大幅度缩短。改变过去伸缩缝的安装在旧桥桥面施工完成以后进行的施工工序,把伸缩缝的替换安装时间前置,并且严格制订施工要求以确保工程质量。
During the reconstruction of Old Bridge, the installation process of expansion joints has always been a technical barrier that plagued the construction workers. The stability and the firmness of the expansion joints failed to meet the design requirements. The installation of expansion joints was the main link that delayed the construction period. Through practice, not only the installation of stability and firmness to meet the design requirements, and construction period has been greatly reduced. Change the past, the installation of expansion joints Bridge construction in the old bridge after the completion of the construction process, the installation of expansion joints replacement pre-installation time, and strict development of construction requirements to ensure project quality.
