Polymer escape pipe, tunnel life pipe, application of escape pipe

&Nbsp; Application of high molecular weight escape pipeline
1
highway tunnel: it is the passage for * * vehicle transportation
With the development of social economy and production, a large number of expressways have appeared, which puts forward higher standards for road construction technology, requiring straight lines, gentle slopes, spacious roads, etc

2
railway tunnel: it is the passage for * * train transportation
When the railway crosses the mountain area, due to the limited traction capacity and the maximum slope limit requirements (less than 24%), it is necessary to overcome the elevation obstacles
It is a reasonable choice to excavate tunnel to cross mountains
Its function is to shorten the line, reduce the slope, improve the operation conditions and improve the traction capacity

3
hydraulic tunnel: a water passage tunnel dug in the mountain or underground
Hydraulic tunnels can be used for irrigation, power generation, water supply, water release, water transmission, construction diversion and navigation
The tunnel with free water surface in the tunnel is called pressureless tunnel; The tunnel that fills the whole section and makes the tunnel wall bear certain water pressure is called a pressure tunnel

4
subway tunnel: a form of railway transportation, refers to the urban rail transit system mainly operating underground, i
e
“ Metro ” Or “ Subway ” (subway, tube, underground); In order to match the built environment and consider the construction and operation costs, many such systems may be converted to ground or elevated sections outside the urban center

5
mine tunnel: refers to the construction method of constructing tunnel by excavating underground tunnel
Mining method is a traditional construction method
Its basic principle is that after the tunnel is excavated, affected by blasting, rock mass breaks and forms a relaxed state, which may collapse at any time

Performance characteristics of ultra-high molecular weight escape pipeline:
1、 Strong wear resistance
The results show that the average annual wear thickness of glass fiber reinforced polypropylene pipe is 11
5424mm/ year; Engineering grade polypropylene pipe (PP) 13
5828mm/ year; High molecular weight polyethylene (UHMW-PE) 5
0104mm/ year; Steel pipe (A3) 36
2424mm/ year; The test results show that the wear resistance of high molecular weight polyethylene (UHMW-PE) pipe is seven times that of steel pipe (A3)

2、 High tensile strength and impact resistance
The impact resistance and impact absorbing energy of high molecular weight escape pipes rank first among plastics, and it is difficult to crack them either under strong external force or internal pressure fluctuation
Its impact strength is 10 times that of nylon 66, 20 times that of poly and 4 times that of poly
Especially in the low temperature environment, the impact strength reaches a higher value
The flexibility of the high molecular weight escape pipeline provides a safe and reliable guarantee for the transportation system

3、 Strong corrosion resistance
(acid, alkali, salt) and organic media (except naphthalene solvent), which are immersed in 80 kinds of solvents at 20 ℃ and 80 ℃ for 30 days, without any abnormal phenomenon on the surface and almost no change in other physical properties  & Nbsp& Nbsp;
4、 Non structural self lubrication
The inner wall of the pipeline produced by the special process is corrosion-resistant, wear-resistant and does not scale, so the flow resistance is very small, and the flow rate and flow rate can be maintained for a long time
Therefore, its inner diameter can be reduced by 15% compared with that of steel pipe; 20%& Nbsp& Nbsp& Nbsp& Nbsp;
5、 Excellent temperature performance
An engineering plastic that can work at temperatures close to zero
At the same time, the product has wide temperature adaptability and can work at -269 ℃ to 80 ℃ for a long time

6、 Strong noise removal capability
The impact energy absorption of high molecular weight escape pipe is the median value of plastic, with good noise attenuation, so as to limit the noise generated by liquid flow during transportation

7、 Safety and health
It is hygienic, non-toxic, free from mildew and bacteria
It meets the indicators specified in national standards
It can contact food& Nbsp;
8、 Easy installation and connection
Good flexibility, can adapt to various geological conditions, and can be directly bent and laid; With chain connection, the connection is safe, reliable, fast, convenient, labor-saving, and fully reflects the use of high molecular weight escape pipes “ Energy saving, economic and efficient ” Advantages of

The tunnel escape pipeline adopts φ 800*30 ultra-high molecular weight polyethylene pipe
The ultra-high molecular weight tunnel escape pipe is light and convenient for disassembly, assembly and handling; The pipeline has good toughness, high impact strength, high ring stiffness, good pressure resistance, not easy to deform, and can be used repeatedly, providing a very safe and reliable guarantee for emergency rescue in tunnel construction
