振动式槽钢止水在复杂环境逆作法顶管工作井及接收井施工中的应用

The Application of vibrating Channel Steel Water Seal in the Construction of Pipe Jacking Operation Shafts and Receiving Shafts Using Reverse Building Method in Complex Environment

结合工程实例,分析了顶管工作井、接收井采用逆作法施工通常采取的几种止水措施。阐述了在复杂施工环境下选用振动式槽钢咬合止水具有对道路交通、周边环境影响小,止水止砂效果好,土层损失小,不影响周围建筑物安全,施工噪音低、震动小,节能和环保效益显著,社会效益非常高的特点,具有良好的推广前景。

Combined with engineering examples,this paper analyzes several water sealing measures generally adopted in the construction of pipe jacking operation shafts and receiving shafts by using reverse building method.It is demonstrated that the vibrating channel steel occlusal water stop under complicated construction environment has the advantages of little impact on traffic and environment,great effects on sealing water and sand,no influence on the safety of surrounding buildings,low vibration and construction noise,significant effects on energy conservation and environmental protection,and it also has great social benefits.Therefore,it has a good prospect of popularization.
