The working principle of the invention is as follows:
during normal construction, the rescue capsule is in a compressed state, the steel skeleton contracts, and the sealing capsule body is in a relaxed state; when emergency situations such as collapse occur in tunnel construction, a gas generator is started through a remote controller to generate a large amount of gas between two layers of canvas of the sealed double-layer cabin body, the gas props open the shell of the sealed double-layer cabin body, and the steel skeleton is driven to extend to the limit from the contraction state; thereby forming a lifesaving space and an escape passage; the escape capsule is internally provided with material conveying pipelines for oxygen supply, water supply and the like, an emergency case, gas emergency materials and the like.
The rescue capsule is formed by connecting a plurality of independent sealed capsule bodies in series; when a single cabin body is damaged and leaks air, other cabin bodies are not affected, and the functions of risk avoidance and escape can be continuously exerted.
The steel skeleton adopts the retractable design, and when normal construction in the tunnel, the steel skeleton is in the contraction state, and whole survival capsule is in the contraction state too, therefore the space that occupies is very little. The extension of the independent rescue capsule is mainly excited by gas expansion, because the gas generator can adopt a remote control gas generator, when an emergency occurs, the gas generator is controlled by a remote controller to generate a large amount of gas instantly, the gas expansion supports the sealed rescue capsule in a contraction state, and the rescue capsule drives the steel skeleton to be converted from the contraction state to an extension state, so that a complete danger avoiding space and an escape channel are formed.
The gas generator is arranged between two layers of sealing canvas of the double-layer sealing rescue capsule, generates ignition action according to the indication of a remote controller signal, ignites fuel (gas generating agent taking NH4NO3 ammonium nitrate, Sr (NO3)2 strontium nitrate and nitryl as main materials) and generates gas to inflate the double-layer sealing rescue capsule, so that the sealing capsule is rapidly expanded.
The telescopic steel skeleton adopts high strength round steel bar to make, and the internal diameter of steel skeleton and independent survival capsule adopts 0.8m, has both satisfied the needs that the people crawled and passed through, is unlikely to again because of the too big intensity loss that leads to the steel skeleton of internal diameter.
The outer shell of the sealed cabin body of the escape capsule adopts a multilayer structure, the outer surface layer is made of polymer canvas materials, the inner layer is made of rubber sealing materials, the outer layer materials are used for resisting slump rock blocks and exerting the functions of bearing pressure and puncture resistance, and the inner layer materials exert the functions of sealing and air leakage prevention.
The single-section rescue capsule is usually in a contraction state, a remote control gas generator is arranged in the air bag, the length of the rescue capsule in the contraction state is about 0.1-0.15 m, when an emergency situation occurs, a worker can excite the gas generator through a remote controller to generate a large amount of gas instantly (0.1 second), the gas is inflated to expand the air bag, so that the air bag barrel-shaped rescue capsule is converted into a stretching state from a compression state in a short time, meanwhile, a steel framework of the rescue capsule is also driven to be converted into an extension state from the compression state, and the extension length of the single-section rescue capsule is 0.3-0.45 m which is 3 times of the length of the compression state; the rescue capsule is light in self weight, is only 1/6-1/10 of the weight of the steel rescue capsule, and is easier to disassemble, assemble and carry.
The whole escape capsule is formed by connecting a plurality of single-section escape capsules, the single escape capsules are connected by adopting high-strength steel buckles, generally, 20-50 sections of independent escape capsules are connected to form an integral escape capsule, when the escape capsule is only used as a danger avoiding space, the length can be controlled within 10m, and a lifesaving space is provided for 5-8 workers;
during tunnel construction, the rescue capsule moves forward continuously along with the forward movement of the tunnel face, and the entrance position of the rescue capsule is kept about 3-4m away from the tunnel face after the rescue capsule extends.
The external maintenance structure of each single escape capsule body is a barrel-shaped air bag structure, the air bag is of a double-layer composite material structure, the outer layer of the air bag is made of high polymer canvas materials and used for resisting the impact of falling stones and preventing the air bag from being punctured, the inner layer of the air bag is made of rubber sealing materials and preventing the air bag from leaking air, a remote control gas generator is arranged in each air bag, a gas generating agent of the remote control gas generator generates a large amount of nitrogen within 0.1 second after being excited, and in order to ensure the strength of the escape capsule, the air pressure after the air bag is filled with the nitrogen is kept between 0.2 and 0.25MPa and is equivalent to the tire pressure of a household car;
water and oxygen supply pipelines 10 and emergency materials 9 are reserved in the escape capsule, and the escape workers wait for rescue.
