随着公路工程施工中新工艺新技术的发展,冲击碾压施工技术因其本身的特点被越来越多的运用到工程建设施工当中。冲击碾压施工就是采用冲击式压实机,配备压实轮,压实轮在牵引机拖动行驶滚动中将高位势能转化为动能对地面进行冲击从而对土体的深层产生较强的冲击能量,同时辅以滚压、揉压的综合作用,使土石颗粒之间发生位移、变形和剪切,随着土石密实度增加,其影响深度也逐渐增加,从而使土体深层随着冲击波的传播得到压实。压实轮在牵引机的拖动下连续作用于地面,使大面积地基得以压实。冲击碾压技术的突出特点是影响深,一般在3M左右,速度快,12-15KM/h,压实质量高。
With the development of new technology and new technology in the highway construction, impact crushing construction technology is more and more applied to the construction of the project due to its own characteristics. Impact crushing construction is the use of impact compactors, equipped with compacting wheels, compacting wheels in traction traction rolling rolling high potential energy into kinetic energy impact on the ground so that the deep soil has a strong impact energy At the same time, the combined effect of rolling and rubbing is combined to displace, deform and shear the soil-rock particles. As the density of soil-rock increases, the depth of influence also gradually increases, so that with the spread of the shock wave Get compacted The compaction wheel acts continuously on the ground under the drag of the tractor, allowing a large area of the foundation to be compacted. Outstanding features of impact rolling technology is the impact of deep, generally about 3M, fast, 12-15KM / h, compaction quality.
