China is laid with axial round pipe for escaping during constructing tunnel usually to solve tunnel cave accident hair at present
The emergency escape hedging problem of Field Force when raw.The common material of constructing tunnel pipe for escaping has armored concrete, steel, poly- second
Alkene material, its working principle is that relying primarily on the elastoplasticity of material to absorb the impact energy of tunnel cave falling rocks, although can
Guarantee that site operation personnel quickly flee from the scene of the accident, reach safety area, constructing tunnel is reduced or avoided, falling rocks occurs and collapses
The casualties of square accident, but exist from it is great, flexible poor, connection is complicated the defects of, simultaneously because carrying at the scene, installation
It is restricted in the process, so that construction cost is higher, construction efficiency is lower.Therefore it proposes a kind of tough with high-strength light, impact
Property good, good leak tightness, quick for installation, convenient disassembly, reusable, lower-cost constructing tunnel pipe for escaping have it is important
Meaning.
Summary of the invention
The purpose of this utility model is the deficiencies in the prior art to be solved, and is provided a kind of with high-strength light, punching
Hit good toughness, good leak tightness, quick for installation, convenient disassembly, reusable, lower-cost constructing tunnel pipe for escaping.
In order to achieve the above objectives, the utility model is implemented according to following technical scheme:
A kind of light flexible constructing tunnel pipe for escaping, is assembled by several duct segments, the duct segments packet

Buffer layer is equipped in the toroidal cavity, the outer shell and hypostracum are FRP layers of fiber composite reinforcing material, the buffer layer
Using the closed air bag of the flexible annular of inflation, two adjacent segment pipe segments are detachably connected by multiple lateral connectors.
Further, the lateral connector includes the wherein segment pipe segment for being set to two adjacent segment pipe segments
Outer shell one end connecting plate, be set to other end duct segments outer shell abutting end the fixation matched with connecting plate
Seat, further includes the bolt for fixed connecting plate and fixing seat.
Preferably, the closure is an integral molding structure with outer shell and hypostracum.
Preferably, the both ends of each segment pipe segment are respectively equipped with four lateral connectors.
Compared with prior art, the utility model has the following beneficial effects:
1) pipe for escaping is using the FRP that density is low, specific strength is high, specific modulus is big, material property is good and designability is high
(fiber composite reinforcing material) is used as outer shell and hypostracum, and using the good annular closed air bag of effect of energy dissipation as buffer layer
Combination is formed, and had not only been highly resistant to falling rocks and landslide impact, weight, but also significantly reduce the own wt of pipe for escaping, and had been convenient for
Onsite moving, assembling, disassembly reduce construction cost and improve construction efficiency.
2) light flexible constructing tunnel pipe for escaping reduces and escapes in pipe in the low noise for resisting falling rocks and the impact vibration that caves in
The psychology of stranger person is frightened；
3) light flexible constructing tunnel pipe for escaping composition section of jurisdiction is produced by factory prefabricating, and tunnel construction site is spelled
Dress, advantageously ensures that construction quality is improved labor efficiency.
