Soft soil refers to soft plastic and fluid plastic clay with large natural water content, high compressibility, low bearing capacity and low shear strength. In modern society, many construction projects are carried out on soft soil such as beach, mud and so on. The nature of soft soil determines that the construction team cannot directly carry out construction on it. The soft soil must be solidified first to form a stable base with certain bearing capacity. The soil stabilization system plays the role of curing soft soil, and uses the cementation of curing agent and soil to enhance the strength of soil.
Phase I Project of Tidal Flat Solidification of Dry Bulk Transportation Trestle Bridge
In October 2017, Shaoxing, Zhejiang province, during the construction of the bridge, the 7-meter-deep silt was solidified, and the entire solidified layer reached 7 meters. After the extension rod was installed, the stabilizer was stirred and transported in the control center. The daily workload is 800 cubic meters, and the solidified geology can contain 120 tons of large-scale equipment entering the site for construction.
The first phase project of in-situ solidification of soft soil on the beach of Hangzhou Bay Expressway
The construction area of the Hangzhou Bay Expressway is located in a mudflat, and the soil is soft. It is impossible to guarantee the construction of heavy equipment such as excavators. The surrounding mudflat must be solidified to ensure subsequent road construction. The total construction volume of the project is 400,000 cubic meters. It uses 9 sets of soil stabilization system equipment, 18 power mixers, and the length of the mixer is 4 meters.
