Escape pipe, tunnel escape pipe, in stock of escape pipe manufacturer, wear-resistant escape pipe

  Through a series of tunnel engineering accidents and their losses, it can be seen that the frequent occurrence of subway tunnel accidents increases the risks in construction
These risks not only increase the cost of tunnel engineering and delay the construction period, but also fail to meet the requirements of safe construction, causing great harm to the society
If we do not install escape pipes in the tunnel, the danger will continue
We need to install escape pipes in the construction tunnel to prevent the tunnel from collapsing, and provide an emergency passage and safe evacuation passage for the construction personnel
We should be responsible for their safety and the country; Once there are casualties and property losses in the project construction, the social negative impact will be great

Construction method and initial support of tunnel escape pipeline:
1
Three step temporary inverted arch method
It is used in the shallow buried and eccentric pressure section of grade V surrounding rock
After the bench excavation, inverted arch or support shall be provided in time to close the initial support into a ring
Adhere to “ Weak, short footage, strong support, early closure, frequent measurement ” Strictly control the excavation footage, strictly control the surrounding hole charge, reduce the disturbance to the surrounding rock, and measure in time to ensure the safety of construction
The grade V surrounding rock of double track tunnel shall be provided with horizontal temporary support or temporary inverted arch
The temporary support shall be made of section steel, and one shall be provided for every two frames in the longitudinal direction

2
Three bench seven step excavation method
It is applicable to the water rich sections of class V surrounding rock generally deep buried, portal shallow buried but not biased, deep buried fault fracture zone, expansive rock (soil), carbonaceous slate and carbonaceous slate
This method has many steps and high process requirements

3
Double wall heading method (also known as eye method)
It is used in the section where the portal is shallow buried and biased or biased class V surrounding rock
This method first excavates the pilot pits on both sides of the tunnel, and then excavates and supports the middle part
Construction method features: good settlement and deformation control, but there are many connection points, complex stress, and high process requirements

Ultra high molecular weight polyethylene escape pipeline has many characteristics:
1
The ultra-high molecular weight tunnel escape pipe has low material cost and saves the procurement cost for the project

2
With strong corrosion resistance, the construction company is simple and fast, and the service life can reach 20-50 years

3
It also has good corrosion resistance and impact resistance under low temperature conditions

4
High toughness and good impact strength

5
Reasonable design and convenient installation
The pipe end shall be equipped with connecting parts and the hanging ring shall be lifted
Ensure installation, lifting and convenience

6
The inner wall of the ultra-high molecular weight tunnel escape pipe is smooth
When an accident occurs, the escape speed is fast and it is not easy to cause secondary abrasion

7
Ultra high molecular weight materials have high impermeability and high mechanical properties
With good comprehensive performance, it has been used in many tunnel projects
