发布时间：2019-06-02 21:03
【摘要】：为了解决桥头跳车问题,武汉西四环线高速公路项目在桥涵台背回填完成后,对桥头及明涵台背进行了高速液压夯实补强。分析了产生桥涵台背回填质量问题的原因,阐述了高速液压夯实机工作原理,介绍了液压夯实工艺以及在本项目台背回填中的应用。得出了通过液压夯实补强,能提高台背回填的压实度,进一步消除工后沉降,降低高速公路运营过程中桥头跳车问题的结论。
[Abstract]:In order to solve the problem of vehicle jump at bridgehead, the high speed hydraulic tamping reinforcement of bridge head and Ming culvert platform was carried out after the backfilling of bridge and culvert platform was completed in Wuhan West fourth Ring Road Expressway project. This paper analyzes on the causes of the quality problems of backfilling on the back of bridge and culvert, expounds the working principle of high speed hydraulic tamping machine, and introduces the hydraulic compaction technology and its application in the backfilling of this project. It is concluded that hydraulic compaction can improve the compactness of backfilling, further eliminate post-construction settlement and reduce the problem of bridge head jump in the process of expressway operation.
