Description

Telescopic emergency escape pipe for high-speed railway tunnel mining

Technical Field

The utility model belongs to the engineering field of fleing relates to emergent the pipe of fleing, especially a high-speed railway tunnel exploitation is with flexible emergent pipe of fleing.

Background

The tunnel is a channel dug in an existing building or an earth-rock structure, is an engineering building buried in the ground, is a form of utilizing underground space by human beings, and can be divided into a traffic tunnel, a hydraulic tunnel, a municipal tunnel and a mine tunnel.

The tunnel facilitates traffic of people, traffic jam of the society is relieved, particularly, with the comprehensive spreading of high-speed railway construction, the exploitation of the high-speed railway tunnel is increased day by day, but the high-speed railway tunnel construction in China starts late, compared with the developed countries in China, the related technical level is still low, and in addition, the characteristics of large road tunnel span, complex construction process, variable terrain and the like cause a plurality of technical problems in the road tunnel construction process.

Although certain results are obtained from related design theories and building processes of tunnels with complex geological conditions along with the increasingly mature tunnel construction technology in China, collapse accidents happen frequently in tunnel construction, and the construction safety problem is very serious. The design and research of the emergency escape pipe with high safety performance have important application significance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome prior art's weak point, provide a high-speed railway tunnel exploitation with flexible emergent escape pipe that design scientific and reasonable, function are various, the security is high.

The utility model provides a its technical problem take following technical scheme to realize:

the utility model provides a high-speed railway tunnel exploitation is with emergent pipe of fleing of flexible, includes support, inner tube and outer tube, the coaxial suit of inner tube in the outer tube, inner tube and outer tube all set up on the support, have seted up the spout on this support, the outer tube can slide in the spout, be provided with the cylinder in the mouth of pipe department of inner tube and outer tube, the drive shaft connection drive axostylus axostyle of cylinder, coaxial cover is equipped with the sleeve on the drive axostylus axostyle, this sleeve hub connection the outer tube the upper and lower side of inner tube has seted up a plurality of slot positions, installs the unit gasbag in every slot position, intercommunicates between every unit gasbag to aerify through air compressor.

And an electric rolling door is arranged at the inlet end of the inner pipe.

And a connecting part connected with other escape pipes is arranged outside the outlet end of the inner pipe corresponding to the inlet end.

The utility model has the advantages that:

the utility model has the advantages of being scientific and reasonable in design, the function is various, the innovation utilizes the sleeve pipe structure to increase the emergent security performance of escaping the pipe, be provided with the gasbag in the inner tube, aerify the gasbag through air compressor, can effectively keep out the external pressure of the dangerous end of collapsing, and cushion through the gasbag, improve the safety guarantee of escaping the pipe, be provided with electronic roll-up door simultaneously at the entry end of inner tube, with rivers or the mud-rock flow of keeping out the collapse, this pipe of fleing is applicable to and installs at the exploitation front end of escaping the pipe, can with ordinary escape union coupling installation use, can certain degree reduce cost, also can select the use segment number according to the in-service use needs, improve the emergent security performance of escaping the pipe energetically, be applicable to and use in dangerous terrain exploitation segment.
