Soil Stabilization System Helps Hu-Hang Expressway Subgrade Consolidation

The construction of the Hu-Hang Expressway is an important project in Zhejiang Province. It provides a reliable transportation guarantee for the economic integration of the Yangtze River Delta and the development of the Hangzhou metropolitan economic circle. Its importance is beyond words. In the construction of expressway, the roadbed solidification is the top priority. According to the plan, the land that the road passes through is mostly puddles and farmland, which are in a situation of long-term immersion in water. Most of these soft soils are cohesive soils with very weak load-bearing capacity, so direct construction cannot be carried out on the surface layer. It is necessary to solidify the shallow soil first to ensure smooth subsequent construction.
