Roadbed treatment method based on vacuum dewatering combined with dynamic compaction
The invention discloses a roadbed treatment method based on combination of vacuum dewatering and dynamic compaction. The roadbed treatment method comprises the following steps: S1, construction preparation; s2, hole drilling and pipe burying: holes are drilled in the precipitation drilling area, a vacuum dewatering well is arranged, a drainage ditch is arranged near the vacuum dewatering well, water pumping equipment is installed for water pumping, a water pumping pipe pumps water in the vacuum dewatering well into the drainage ditch, and the underground water level is controlled to be below the roadbed treatment depth; S3, dynamic compaction filling: the soil layer of the dynamic compaction area is evenly tamped and filled with reinforcements, the filling height is the roadbed treatment depth, the reinforcements and the treated soil layer jointly form a dynamic compaction reinforcing layer, and the reinforcements are one or more of hard rock fragments, concrete fragments and construction waste fragments; S4, laying of a structural layer. According to the treatment method, the pore water pressure in the roadbed is reduced, the tamping effect during dynamic compaction is better achieved, post-construction settlement of the roadbed is reduced, and the bearing capacity of the roadbed is effectively improved.
本发明公开了基于真空降水联合强夯的路基处理方法，包括以下步骤：S1.施工准备；S2.钻孔埋管，在降水钻孔区钻孔，设置真空降水井，真空降水井附近设置排水沟，安装抽水设备进行抽水，抽水管将真空降水井内水抽入排水沟内，控制地下水位处于路基处理深度以下；S3.强夯填充，将增强体均匀夯实并填充在强夯区的土层内，填充高度为路基处理深度，增强体和处理后土层共同形成强夯加固层，所述的增强体为硬质岩石碎块、混凝土碎块或者建筑垃圾碎块中的一种或几种；S4.铺设结构层。本发明处理方法降低了路基中的孔隙水压力，更好的实现强夯时的夯击效果，减少路基工后沉降，且有效提高了路基承载力。
