What are the connection modes of escape pipes? Which connection method is OK?

&Nbsp; What are the connection modes of escape pipes? Which connection method is OK? Zhongxiong pipe industry provides two connection modes, which are introduced as follows
Hoop connection:
After years of construction experience and project feedback, there are two kinds of reserved, and this is one of them
It belongs to hard connection
The hoop made of steel conforming to the pipe diameter is used
This connection method has a neat appearance, which is not conducive to adjustment in case of slow bending of the tunnel
If the construction section is flat, this connection method is no problem

Chain connection:
Chain connection is the most cost-effective connection method currently used
It is convenient to connect without complex hair process
Just put the chain into the U-shaped card, insert it into the card slot reserved in advance by the pipe, and screw it up
The construction is simple and fast, and the connection strength is high
Generally, it takes only 2 minutes to connect two pipelines
Moreover, this connection method is very easy to adjust in case of uneven road surface or slow bending
The chain can be extended and retracted to make the pipeline better fit the road surface, so this connection is the most commonly used one at present

Requirements for material selection of tunnel escape pipeline
1
The escape passageway has good impact resistance and can withstand the severe impact of large stones when the tunnel collapses

&Nbsp 2
The diameter of the escape passage shall be large
Generally, the specification of the commonly used escape passage is dn800-dn860mm, which is more suitable for human crawling

Advantages of Zhongxiong pipe industry tunnel escape pipeline:
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
