清连高速特大桥高墩砼泵送施工的控制

在悬臂式特大桥高墩施工中，砼泵送施工控制极为重要。对高墩泵送砼进行切实可行的控制要做到：选择最佳配管设计，正确处理管道连接；严格要求卧泵操作手规范操作；加强混凝土拌和楼管理，严格控制混凝土拌制质量等。文章对高墩砼泵送施工中的配管设计、管道连接、卧泵操作、拌和楼管理、砼拌制质量控制等进行了阐述。对同类桥梁高墩施工具有一定的参考意义。

The Quality Control on the Construction of Cantilever Beam-Bridge with High Pier in Qinlian Expressway

During the construction of cantilever beam bridge with high pier, quality control over pump concrete is vital important. To achieve feasible quality control over pump concrete, we must choose the best piping design, make correct pipeline connection, rigid pump operation, strengthen the management of concrete mixing plant and tighten control over mix blend. The article also elaborates on piping design, pipeline connection, pump operation, management of mixing plant quality control of concrete. It has some reference value for the construction of bridge pier.
