Tunnel construction, expressway tunnel escape pipe, light escape pipe

  Tunnel construction, expressway tunnel escape pipeline, light escape pipeline expressway is the mainstay of China's transportation industry
Its rapid development marks the forward speed of China's transportation industry, and also facilitates people's travel
Due to the high concealment and great construction difficulty in the construction process of expressway, special attention should be paid to the technical requirements and quality safety guarantee in the construction project
It is not only necessary to formulate a detailed construction technical scheme, but also to have a complete quality and safety management system

Relevant requirements for setting of tunnel escape pipeline:
1
  The construction site shall be provided with adequate ventilation, tunnel escape pipes and alarm facilities as required

2
the operation time limit system shall be implemented for the construction of tunnel works, and the work with high risk shall be stopped at night

3 in terms of tunnel escape pipe support, the construction unit shall strictly manage the tunnel construction support construction process, and it is strictly prohibited to support lagging and safety step mark

4
the construction unit shall select qualified units to carry out hydrogeological prediction and monitoring measurement before the tunnel
The former geological prediction and monitoring measurement units shall improve the quality of prediction and monitoring, and timely and accurately feed back to the entrants

5
in terms of tunnel collapse, a special safety construction scheme shall be prepared, a tunnel safety team shall be established, and sufficient safety personnel shall be allocated

6
the construction unit shall formulate emergency response plan as required, establish emergency rescue team, allocate emergency rescue personnel, etc
, and regularly organize emergency escape drills for the construction, supervision and design units

7
if possible, carry out mechanized operation to reduce the number of operators
Tunnel escape pipeline above 1km
The entry and exit of tunnel personnel and vehicles below 1km shall also be regulated, and irrelevant personnel are strictly prohibited

Characteristics of Tunnel Engineering:
(1) High design standard
The design structure requires high stability and long design life
Ensure the uniformity of the longitudinal stiffness of the line by setting the road bridge transition section; High performance concrete is used for bridges and durable concrete is used for tunnels to ensure the durability of structures

(2) There are many types of engineering structures with long lines
The main line of the civil works of the construction pipeline section is 13
05km long, and the single length of the bridge is 4522m (another ramp bridge is 616m), accounting for 17
3% of the total length of the line; The length of single tunnel is 5202m, accounting for 19
9% of the total length of the line; The subgrade accounts for 62
8% of the total length of the line
There are 18 channels, 12 slab culverts and 14 circular pipe culverts
The line is long, the project scale is large, and there are many structural types
During the construction, great attention should be paid to scientific organization, careful arrangement, good construction process arrangement and reasonable allocation of various construction materials

(3) High environmental requirements
The project section has developed vegetation along the line and is close to villages, so the environmental protection requirements are high

Luoyang Zhongxiong Pipe Industry Co
, Ltd; A new, modern and high-tech enterprise with internet thinking
Specializing in the production of tunnel escape pipes, steel belt reinforced PE spiral corrugated pipes, ultra-high molecular weight polyethylene pipes, escape pipes, municipal pipes and other pipe series products, the products are widely used in, chemical industry, electric power, mining, metallurgy, water conservancy, municipal administration, construction, environmental protection, coking, coalification, dredging and other industries

Comprehensive performance of tunnel escape pipeline:
1
The tunnel escape pipe is light, only about 1/8 of the steel pipe weight, and it is convenient for disassembly and handling

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

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

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

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
