Safe and reliable rapid rescue device and rescue method after tunnel collapse

Abstract

The invention relates to a safe and reliable rapid rescue device and rescue method after tunnel collapse. The rapid rescue device includes a pipe jacking machine with a built-in belt conveyor, a radar life detector, a steel pipe jacking machine with a built-in lighting device, and a jack. After the tunnel collapses, the working shaft is quickly excavated and a jacking machine with a built-in belt conveyor is installed in the working shaft. The pipe jack and radar life detector, the steel pipe jacking machine with built-in lighting device, the jack, and then the pipe jacking machine with built-in belt conveyor are used for excavation rescue. The radar life detector detects signs of life in the collapsed ruins, allowing rapid and accurate rescue. Reach the rescue position, and then transport the trapped persons out through the rescue channel formed by the pipe jacking machine with built-in belt conveyor and the steel jacking pipe with built-in lighting device through the belt conveyor. The invention can provide safe, reliable and rapid rescue after collapse occurs during tunnel construction.

Description

technical field [0001] The invention relates to the technical field of underground research of civil engineering such as soil excavation and tunnel excavation, and specifically relates to a safe and reliable rapid rescue device and rescue method after tunnel collapse, which can be safe, reliable and fast after tunnel collapse occurs. rescue. Background technique [0002] Nowadays, in order to make better use of underground space and effectively protect the ecological environment on the ground, people are vigorously developing underground space technology, developing and utilizing space resources below the ground, and building underground houses and underground structures, including road tunnels, water Underground tunnels, underground railways, pipe galleries and underground crossings and other underground buildings. Due to various influences such as construction reasons, design reasons, and complex geological conditions, the collapse of the tunnel has become an important is...

AI Technical Summary

Problems solved by technology

[0004] (1) Ordinary rescue uses manual excavation, or calls some large machinery such as excavators. It takes a long time to excavate with manual and such machinery. At the same time, the excavation of large machinery requires a good working environment. If the limit is too large, the rescue operation cannot be carried out, and the lives of the trapped persons are threatened

[0005] (2) General rescue will carry out temporary support after excavating the escape channel. The support method is single, which is likely to cause a secondary collapse, and cannot safely and reliably guarantee the life safety of the rescuers. At the same time, after the rescue, many support methods The structure needs to be demolished, which consumes a lot of manpower and financial resources

[0006] (3) Before the rescue, it is necessary to carry out a large number of exploration designs and formulate a feasible rescue plan. At the same time, the construction is also difficult, which undoubtedly increases the rescue time and seriously affects the life safety of the trapped people.

[0007] (4) How to transport the wounded reasonably and effectively when carrying out rescue after the collapse of the tunnel has also become a problem. It is often difficult to transport the wounded out of the trapped place due to environmental constraints
