The raw material of UHMWPE escape pipe is ultra high molecular weight polyethylene
material with viscocity average molecular weight is more than 1500000.
UHMWPE pipe has property of light weight, convenient disassembly and transportation, good
toughness, high impact strength, the instantaneous deformation under strong impact,
absorbing impact energy and rapid recovery.
The escape pipe provides safe and reliable guarantee for the construction of highway tunnel
emergency escape pipeline.UHMWPE escape pipe has high ring stiffness, good pressure
resistance, not easy to deformation, in highway tunnel construction collapse, bearing
capacity and anti environment damage ability far more than the general pipeline.

DN800mm UHMWPE pipe
Advantage of UHMWPE escape pipe:
The escape tunnel has excellent comprehensive properties. There is no other enginnering
The escape tunnel has excellent comprehensive properties. There is no other enginnering
plastics comparable to UHMWPE's shock resistance, high pressure resistance, abrasion
resistance, aging resistance, light weight, and chemical corrosion resistance, non-toxic,
no easy adhesion, in foreign countries known as "magical plastic". Therefore, it is widely
no easy adhesion, in foreign countries known as "magical plastic". Therefore, it is widely
used in the fields of machinery, transportation, textile, paper making, mining, agriculture,
chemical industry and so on.
- light weight, which is about 1/8 of steel weight, convenient disassembly and
transportation.
-The pipeline of good toughness, high impact strength, the instantaneous deformation under
strong impact, absorbing impact energy, and then quickly restore to the original shape,
provides safe and reliable guarantee for the construction of highway tunnel emergency
escape.
-The UHMWPE pipe has high ring stiffness, good pressure resistance, not easy deformation, in
highway tunnel construction collapse, bearing capacity and anti environment damage ability
far more than the general pipeline.
From 2004 to 2007 according to the tunnel construction accident statistics, 39 occurred in
China (highway, railway tunnel construction accidents). Due to the diversity and complexity
of the geological conditions, the occurrence rate of the highway tunnel construction is
higher than that of other geotechnical engineering.
Therefore, the collapse of emergency rescue technology of highway tunnel construction will
be able to effectively reduce casualties and property losses of the construction of highway
tunnel collapse accident, which has important practical significance to improve the safety
of highway tunnel construction. However, the existing emergency rescue channel of current
road tunnel construction is steel pipe,which is very heavy, more bulky, inconvenient
disassembly and transportation, low efficiency of use. At the same time, in the selection of
emergency rescue pipeline, the pipeline needs to have high impact resistance, high pressure
resistance, high wear resistance and other excellent properties.
The feasibility of using super high molecular weight polyethylene pipe to the emergency
rescue channel of highway tunnel was demonstrated by the impact test and pressure test.
Meantime, from the angle of human engineering, the structure size of the new type of
emergency rescue channel is optimized.
