南桥渡槽拆除重建施工技术

Construction technology of demolition and reconstruction for Nanqiao aqueduct bridge

针对南桥渡槽年久失修产生的病害,结合标段内工程特点和混凝土生产系统工艺,讨论了渡槽拆除和重建的施工方法。工程区现有条件表明,渡槽附近石料质量和储量均能满足工程用石料和混凝土骨料的要求,可直接降低工程运输成本和建设工期,为实现工期目标提供保证。

According to a fact that Nanqiao aqueduct have fallen into disrepair resulting to serious diseases, construction method of demolition and reconstruction for the aqueduct bridge was discussed combined with engineering characteristics of the construct section and technology of concrete production system. The existing conditions of the project area show that both quality and reserves of the stone near the aqueduct bridge can meet the requirement of engineering stone and concrete aggregate, thus directly reducing the transportation cost and construction period. Furthermore, a reasonable construction procedure and strict progress control network plan will give a guarantee to reach the goal of the project.
