Zhongda consulting through the site's knowledge of the building knowledge column of the knowledge collation, the wind volcano tunnel basic situation is as follows:
The wind volcano tunnel is located in the hinterland of the Qinghai-Tibetan Plateau, Coco-Cecil, "no man's land" edge, bounded by the Kunlun Mountains and the Tanggula Mountains, the total length of 1338 meters, the import rail elevation of 4905 meters, the wind volcano tunnel. Total length of 1338 meters, the import rail surface elevation of 4905 meters, is currently the world's highest elevation railroad tunnel. Tunnel is located in the wind volcano pass alpine cold and lack of oxygen, low temperatures, large temperature differences between day and night. Altitude of 4905 meters, the average annual temperature of minus 7 ℃, the lowest temperature in the cold season of minus 41 ℃, the oxygen content in the air is only about 50% of the mainland, has been referred to as "the forbidden zone of life". Tunnel body is located in all the frozen soil, frozen rock, complex geological formations, set of frozen soil, ice-rich frozen soil, fissure ice, siltstone and other harsh geology in one, soil quality is tight and mixed.
Wind volcano tunnel air is very thin, a serious lack of oxygen, even if the staff are carrying oxygen tanks, or not enough, a drop in the bucket. In order to ensure that the team to go, stand firm, win, they start from the geographical environment, climatic conditions, technical difficulties, materials and equipment, medical and health care and other aspects of security. Has invested funds to set up a high-pressure oxygen warehouse, B ultrasound and other advanced medical equipment, "site hospital" and 9 grass-roots site health center, equipped with 34 medical personnel, formed a sound secondary health protection network; they cooperate with scientific research units, developed and built 3 production, life medical oxygen station, to the wind volcano tunnel for diffuse oxygen supply, each oxygen station every time to the wind volcano. Oxygen supply, each oxygen station can produce 20 cubic meters of oxygen per hour, the purity of oxygen reached 94%, and installed oxygen trucks in the cave to facilitate the operation of the staff at any time to absorb oxygen. Solved the problem of more than 3,000 construction workers and civilian laborers using oxygen for construction and life. Created a miracle that none of the construction workers and laborers died of plateau sickness. Sandstone and other harsh geology in one, the soil is strict and mixed.
