CTCI REI’s ground freezing process is safe, environmentally friendly, and delivers uniformly excellent performance. It also allows the ground to recover easily once the freezing process is complete.
- Ground Improvement Work of CK570C of Hsin- Chong Line,Taipei MRT systemThe Taipei MRT System Hsin-Chong line is divided into the west bound Hsin-Chong Line and north bound Luzhou Line at the turnout structure by the left side of the Danshui River.
Because of the special route plan, the turnout structure shall provide shield tunnel with two TBM launch sites and four arrival-sites to decompose the shield. Considering the nearby buildings, the variety of geological structures, great depth, high hydraulic pressure and the groundwater flow, the ground improvement methods include not only the super jet grouting but also the artificial ground freezing method to protect and stabilize the soil body during breaking the mirror-face. Because the freezing method have to be coordinated with the structure construction, the difficulty and the complexity of the freezing method is one of its kind.
