摘要
结合长邯高速公路改扩建工程实例,介绍了高速液压夯实机的压实机理,阐述了V形沟、"三背"回填及新旧路基拼宽部等特殊地形条件下,高速液压夯实机补强路基的关键技术,实践表明,该技术提高了路基的强度,缩短了工期,降低了施工成本,经济技术效益显著。
Combining with the Chang-Han highway extension engineering,this paper introduced the compaction mechanism of high speed hydraulic ramming machine,elaborated the key technology of high speed hydraulic ramming machine reinforcement roadbed under V-shaped groove,＂three＂structures＇ back fill and new and old roadbed width and other special terrain conditions,the practice showed,the technique improved the roadbed strength,shorten the construction period,reduced the construction cost and had significantly economic benefits.
