Escape pipe, Zhongxiong pipe light escape pipe, new escape pipe

&Nbsp; By the end of 2017, the total number of highway tunnels in China had reached 5426, a total of 319× 104KM, however, the construction of highway tunnels in China started late
Compared with foreign developed countries, the relevant technical level is still low
In addition, the characteristics of highway tunnels, such as large span, complex construction technology and changeable terrain, lead to many technical problems in the process of highway tunnel construction
Although with the new construction technology of highway tunnel becoming more and more mature in China, the relevant design theory and construction technology of tunnel crossing complex geological conditions have achieved certain results, collapse accidents have occurred frequently in tunnel construction, and the construction safety problems are extremely serious
Comprehensive performance of tunnel escape pipeline:
&Nbsp; 1
The tunnel escape pipe is light, only about 1/8 of the steel pipe weight, and it is convenient for disassembly and handling

&Nbsp 2
The tunnel escape pipeline has good toughness and high impact strength
It deforms instantaneously when impacted by strong external forces and absorbs a large amount of impact energy
It can be used normally under polar temperature and its physical properties are not affected by low temperature, which provides a great guarantee for emergency rescue of tunnel construction escape

&Nbsp 3
The escape pipe ring of the tunnel has high rigidity, good pressure resistance and is not easy to deform
It can absorb the impact force and is not easy to be damaged in case of collapse during the construction of highway tunnel

&Nbsp 4
The tunnel escape pipe is easy to install, connected by hoop and chain, and easy to disassemble

&Nbsp 5
The tunnel escape pipe can be reused
It is made of ultra-high molecular weight material, which has good anti-aging performance, slow embrittlement performance and theoretical service life of more than 100 years
Material and setting requirements of escape pipe:
According to the results of repeated experiments and relevant theoretical data, the size of the tunnel escape pipe is not easy to be too small, it is easy to damage the escape pipe in case of collapse, and the size will increase the cost, which is not conducive to the transfer in construction
Combined with Hertz research results, the size of tunnel escape pipe is determined as 800mm outer diameter and 30mm wall thickness

The materials of UHMWPE escape pipes in Zhongxiong pipe industry are compared with those of steel pipes and glass fibers

(1) The ultra-high molecular weight escape pipeline of Zhongxiong pipe industry is a linear thermoplastic engineering plastic with an average molecular weight of more than (2
5) million, which is composed of polyethylene and butadiene monomers under the action of catalyst
The specification of the new light escape pipe professionally produced by our company is φ 800*30mm、φ 860*30mm each section is 3M and 6m long, and weighs 69
7kg per meter (steel pipe weighs 210kg per meter)

(2) Steel pipe material, steel escape pipe
The transportation cost of steel pipe is relatively high, time-consuming, easy to deform, corrosion resistance and poor wear resistance
It is not recommended to use
Specification of steel escape pipe: φ 820*10mm,φ 1020*10mm,φ 1120*10mm。
(3) Glass fiber material, 630*14mm in specification
As the cost performance is not as good as the above two, UHMWPE escape pipes are commonly used in the market
