根据焦作市通车节点目标要求,倒排工期后,焦东路桥梁搭板下回填时间需在7-8d内完成,在天气、水泥土与渠堤填土过渡衔接等因素影响下,采用原设计水泥土回填方案施工实施难度大,并且搭板下填筑完成后无沉降等待时间,将给通车后产生跳车的潜在风险,留下较大的安全隐患。采用泡沫混凝土填充则可以解决以上问题。
According to the target of Jiaozuo opening to traffic nodes, the backfilling time of JiaoDong Road Bridge should be completed in 7-8d after the inverted construction period. Under the influence of the weather, the transition of cement soil and drainage embankment, etc., the original design Cement soil backfill program construction is difficult to implement, and take the board to fill the completion of the settlement without waiting time, will give the potential risk of traffic jams, leaving a big security risk. Foam concrete filled can solve the above problems.
