冲击压实技术在山区旧水泥砼路面修复中的应用

Research on the Application of Impact Compaction Technology in Rehabilitating Engineering of Mountainous Old Cement Concrete Pavement

冲击压实机是一种高冲击能量的压实机械,通过破裂稳固混凝土路面,使旧路面形成嵌锁型结构,成为新铺路面的垫层或底基层。结合省道S249线坪乳公路改造工程,简要介绍了冲击压实机的工作原理,冲压施工工艺,重点对沉降效果和破烈块度进行了分析,并指出了当前冲压检测方法存在的问题。

Impact compactor is a compaction machinery with high impact energy, which cracks the old cement concrete pavement to form a interlocking structure and be the cushion or sub-base of the new pavement. Combined with the S249 Pingru provincial road innovation project, a brief introduction is given about the working principle of impact compactor, the construction technology of impact compaction, makes typical analyses on the effect of the settlement, and puts forward the existing problems of detection methods of impact compaction.
