Description
Technical Field
The utility model relates to a tunnel engineering field, especially a high altitude tunnel oxygen system.
Background
The air in the high-altitude area is thin and has serious oxygen deficiency, and the oxygen content in the air is only 50 percent of the sea level. The thin air can cause headache, dizziness, palpitation, chest distress, short breath, nosebleed and vomiting. If the construction operation is carried out under the high-altitude environment condition, constructors not only bear the infliction and pain of the strong altitude reaction and face the threat of health damage and life safety, but also have extremely low labor efficiency and can not ensure the construction progress and quality. Therefore, safe, reliable, economic and scientific effective measures are taken to supply oxygen to the construction places in the high altitude areas, and the oxygen supply device has important significance for guaranteeing the health and life safety of constructors, improving the working efficiency and the like.
