Artificial Freezing for by-Pass of Subway Tunnel
Artificial freezing method is a special construction method for geotechnical engineering, which freezes the water in the soil around the underground excavation space into ice with artificial refrigeration technology. The soil and ice will be cemented together to form a freezing wall or a closed underground space, which can isolate the groundwater and bear the earth pressure. So the underground construction can be carried out under the protection of the freezing wall. In practical, the ammonia-brine refrigeration technology is used in most of the projects. The ammonia-brine system consists of brine circulation system, Freon circulation system and cooling water circulation system.
