Project Cases

The century-old strategic project "Sichuan-Tibet Railway" is a nationally significant and landmark project decided by the Party Central Committee and the State Council. Among them, the terrain, geology and climatic conditions of the section from Ya'an to Nyingchi are more complicated, and the difficulty of construction is rare in the world.

In March of this year, ZOY successfully won the bid for the Sichuan-Tibet oxygen supply project, and participated in the construction of the Sichuan-Tibet Railway with excitement and pride, giving full play to its own light and heat, and providing strong oxygen supply support for the great builders.

In order to improve the plateau anoxic response, in the overall oxygen supply project, ZOY is the project department of China Construction and the resident of the Waze Bridge and Xinduqiao Tunnel Station are equipped with 120 cubic meters of large-scale central oxygen production equipment, 90 cubic meters of central oxygen production equipment and 45 cubic meters of central oxygen production equipment, with a total of diffuse oxygen supply space of over 20,000 cubic meters; The construction personnel provided timely supplementary oxygen to avoid safety accidents caused by hypoxia.

It is worth mentioning that ZOY 120m3 medical oxygen generating equipment is the largest oxygen generating unit in the whole line of the Sichuan-Tibet project. The oxygen diffusion space of a single unit is about 10,000 m3, and the noise of the equipment is less than 50 decibels. Under continuous operation 24 hours a day The performance remains stable, which is one of the biggest highlights in the whole project.
