采用高速液压夯实机对中原地区某高速公路改扩建工程的新老路基结合部位进行处理,探讨高速液压夯实机对新老路基结合部位差异沉降的控制作用。基于HC型高速液压务实机的工作原理和施工工艺,确定了低液限黏土路基的含水率、沉降量、压实度与随着不同档位的变化规律,提出了高速液压夯实机的合理夯实档位。
The high-speed hydraulic tamping machine is used to deal with the combined parts of old and new roadbed in the reconstruction and expansion project of a highway in the Central Plains to discuss the control effect of high-speed hydraulic tamping machine on the differential settlement of the new-old roadbed. Based on the working principle and construction technology of HC-type high-speed hydraulic concrete machine, the moisture content, settlement, compaction degree and the changing law with different gear positions of low liquid limit clay subgrade were determined, and the reasonable compaction of high-speed hydraulic compaction machine Stalls.
