泡沫轻质土在沾临高速路桥过渡段路基处理中的应用

Application of foam light soil in roadbed treatment of Zhanhua-Linzi highway project road bridge transition section

针对路桥过渡段路基处理中的特殊要求,采用泡沫轻质土对桥梁台背和组合式涵洞进行回填。以沾化至临淄公路为依托,通过实际工程的应用效果可知,常规填土通常难以在台背处压实,而泡沫轻质土通过自身自流性,能很好地解决台背处回填问题。利用泡沫轻质土方案比常规处理方案工程造价更低,更节省成本、施工性强,可以有效解决工程中结构物间台背填料难以压实施工的难题。

In view of the special requirements in the roadbed treatment of the transition section of the road bridge,the bridge abutment and the combined culvert are backfilled using foam light soil to backfill it in order to Zhanhua-Linzi highway project,through the application effect of practical engineering can be seen,conventional filling is usually difficult to compact at the back of the abutment,and foam light soil through its own self-flowing special performance is very good to solve the backfill problem at the back of the station.The use of foam light soil scheme than conventional treatment program project cost is lower,more cost-saving,strong construction,can effectively solve the project between the structures of the back filler difficult to press the implementation of the problem.
