Tunnel construction collapse prevention, Zhongxiong pipe industry escape pipeline

  With the continuous development of highway tunnels, the requirements for construction technology are also increasing
Combined with practical projects, this paper analyzes the construction characteristics and difficulties of highway tunnels, and puts forward corresponding solutions, which provide reference standards for the construction, construction technology and quality management of highway tunnels

Omen before tunnel collapse
When a tunnel is built in a section with poor geology, it often encounters serious accidents such as roof surrounding rock staying, side wall sliding, and even roof falling
These phenomena are called collapse in construction
Landslides threaten personal safety, delay the construction period and make the surrounding rock more unstable
Therefore, it should be prevented during construction, and timely and accurate treatment should be carried out after the collapse to reduce the harm caused by the collapse

The deformation, failure, instability and collapse of surrounding rock is a process from quantitative change to qualitative change
In the process of quantitative change, some symptoms will inevitably appear in the engineering geological and hydrogeological characteristics of surrounding rock and rock mechanics
According to these signs, the stability of surrounding rock is predicted, and geological advance prediction is carried out, so as to ensure the safety of construction personnel and prevent tunnel collapse

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

Zhongxiong pipe industry suggests that during the construction of tunnel engineering, the engineering unit should select qualified units to carry out tunnel advance hydrogeological prediction and measurement
The advance hydrogeological prediction and measurement units should improve the quality of prediction and monitoring, and timely and accurately feed back to the construction, supervision and design units
When abnormal conditions such as large deformation and velocity of surrounding rock are found, the construction unit shall immediately organize the withdrawal of construction personnel

Requirements and application of pipes for tunnel escape pipeline:
1
ensure that the thickness of the tunnel escape pipe is not less than 30mm

2
the length of each tunnel escape pipe is 3M

3
the tunnel escape pipe can be removed manually, and the connection is firm and safe

4
when the tunnel escape pipe is temporarily removed, it shall be removed section by section
It is strictly forbidden to remove it in place at one time

5
the tunnel escape pipeline shall be flat, dry and smooth, and shall not be used for other purposes than emergency escape

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 for a long time, providing great safety and guarantee for emergency escape in tunnel construction
