桥梁施工中质量通病的控制与对策措施

Quality Control and the Way to Deal with the Common Failing in Bridge Construction

通过加固地基和采用轻质材料回填,有效地控制桥头软土路基沉陷跳车;通过桥面砼侧模整平系统施工新工艺精确控制桥面铺装层顶面标高,采用整体式大型钢模板工艺使防撞护栏质量有明显的提高,采取反开槽安装伸缩缝施工工艺,使伸缩缝安装平整度质量得到有效控制.

The following measures to deal with the common failing in bridge construction are discussed. The settlement of soft foundation soil at the end of bridge and the car jumping are brought under control effectively by means of strengthening foundation and light weight material backfilling. The top level of the bridge pov-ement is brought under control accurately with the aid of new construction technique about side form leveling system for bridge surface concreting. The quality of fence for striking protection is improved significantly by means of integrated large-scale steel form technique, The deviation in level for expansion joint installation is brought under control with the aid of expansion joint installating after backward trenching technique.
