Construction of a deep ventilation of 175 m depth by using artificial ground freezing in Taiwan
Abstract
The shaft at Anso no. 3 tunnel in south link railway project of Taiwan we have use artificial ground freezing method to built . The shaft has 175m depth with a light diameter of 5.5m . The lining thickness is 50cm . There are totally 32 freeze tubes of 120m depth to freeze the fracture zone between El. 224.83m—154.32m which is 70.51m thick. With this new method the project engineers has successfully stop the groundwater intrusion and learn to this new technology.
