Railway Tunnel Cooling Projects
Introduction: This is currently the longest tunnel of the Lhasa-Nyingchi Railway, with a total length of 7684m and an altitude of 3164m. The single-track tunnel length is 7309m, the station tunnel is 375m and the maximum buried depth is 1237m.
Solution: 5 ton block ice maker
Application: tunnel cooling
Introduction: At 9:50 on November 2, 2019, the Bayu Tunnel, a key control project of the Lhasa-Nyingchi Section of Sichuan-Tibet Railway, was successfully completed, which was listed as a class I high-risk tunnel by the State Railway Corporation. During the construction, it created the highest record of 7015 meters of blind-heading in plateau railway tunnel.
Solution: tunnel cooling
Equipment: 3 ton block ice machine with ice tank
Application: ice tank for water adding, ice block storage
Gangmula Mountain tunnel locates in Tibet Autonomous Region, one of the whole line control project of Lalin Railway. The tunnel is located in the earthquake zone and is a national high-risk tunnel. Geothermal, rock burst, fault are the major problems. The total length is 11,660m, and the single-track tunnel length is 11.357m, with a station tunnel length of 303m. The maximum burial depth is 1,800m.
Introduction: Zhengzhou-Chongqing high speed railway has a total length of 818 kilometers and a designed driving speed of 350 km/h.
Equipment: 5 ton saline block ice maker
Application: tunnel cooling
Introduction: Zhengzhou-Chongqing high speed railway has a total length of 818 kilometers and a designed driving speed of 350 km/h.
Equipment: 10 ton saline block ice maker
Application: ice making and providing
Introduction: Zangga tunnel is located in the Yarlung Zangbu Grand Canyon, Tibet, with an altitude of more than 3500m. With a total length of 8.876 kilometers, it is an I-class high-risk tunnel and listed as a whole line controlled key and difficult project.
Solution: 5 ton block ice maker
Application: tunnel cooling. The air in the tunnel is thin and has low oxygen content. The wall temperature reaches as high as 60 ℃ and the block ice is used for cooling the tunnel. In the picture, workers are carrying the ice blocks.
