Abstract: With the construction of new rural areas, the concept of “Highway Beautification” is being fully integrated into the construction process, and the principles of “no damage is the greatest protection” and “resource conservation, lowcarbon cycle” are creatively followed to optimize the better utilization of land resources. The selected project is to be built into a harmonious and unified with “highway, nature, and humanity”, with green, environmental protection, and local characteristics. The implementation of the in-situ solidification technology has improved the efficiency of the soft soil improvement and reduced the pollution caused by the waste soil and contaminated soil to other land resources and rivers. The soft soil is solidified on site, reducing the utilization of sands and gravels, and allowing zero discharge of the engineering soil waste, reducing the environmental impact of waste earthwork transportation and piling, improving the water and soil environment of the construction site, saving land resources, and reducing treatment costs. The in-situ solidification technology can provide effective support for soft foundation treatment.
