Description

Tunnel collapse emergency life support pipeline

Technical Field

Although the escape pipeline is arranged in the tunnel construction according to the standard regulation, the pipeline is generally short in length, and the collapse place is uncertain, so that the collapse place and the escape pipeline are often not in the same position, and the expected escape effect cannot be achieved in practice. The long escape pipeline can bring influence to tunnel construction, and because the escape pipeline is large in diameter, heavy in weight and not suitable for moving and arranging, operators conflict with the arrangement of the escape pipeline, move untimely and put randomly, and the effect of the escape pipeline is weakened more.

In tunnels in areas with poor geological conditions, collapse and roof collapse accidents often occur in construction, commonly known as closing doors. When such accidents occur, operators are often isolated on the face by the collapse body and isolated from the outside, communication between the isolated operators and the outside is also blocked, and the condition of the face is difficult for the outside operators to know. Under the conditions of extremely poor geology, larger collapse and long duration, rescue work cannot be timely carried out due to the fact that collapse is continuously unstable, and blocked operators are not supplemented with water, food and oxygen for a long time, so that life health is threatened. When the tunnel collapses and the roof is closed, a life support channel is constructed by firstly thinking, and food and water are delivered to the hands of blocked people to maintain the nutrients necessary for the life support of the people. Meanwhile, communication connection is established with blocking people, the emotion of the blocking people is calmed, when injured people exist, some emergency medicines are delivered through a life channel which is opened by rescue, temporary treatments such as wound packing are carried out, then collapse bodies are treated, people enter and exit a rescue channel are opened, and the blocking people are rescued and sent to a doctor.

Because the emergency rescue professional team and professional equipment for tunnel collapse are often far away, personnel and equipment dispatch needs time, and because of the soil texture of the collapse body, the construction of the life channel needs to be constantly replaced and optimized in the process of fumbling and understanding the soil texture of the collapse body, 2-3 days are often required for opening, and 7-10 days or even longer are required for opening the rescue channel for personnel to enter and exit.
