How much is one meter of Dongying polymer escape pipeline

  Shuangshan tunnel of Liuwei Expressway Shuangshan tunnel is the Zui long tunnel of Liuwei Expressway and the Zui long high gas highway tunnel in Guizhou

Shuangshan tunnel is located at the junction of Xiaohai Town, harahe Township and guanfenghai town in Weining Autonomous County, with an altitude of 2300 meters and a total length of 5083 meters
The tunnel adopts two-way construction at the inlet and outlet ends, and the outlet end is constructed by Guizhou Road and Bridge Group Co
, Ltd
It is designed according to the two-way four lane standard, and the design speed is 80 kilometers per hour

Liuwei expressway is an important section of Duyun Shangri La expressway, a newly added encrypted line in the national expressway network, and it is the "Guizhou expressway network planning" “ 6 horizontal, 7 vertical and 8 couplets ” And the four urban ring roads “ The seventh vertical ” And Liupanshui ring expressway
After the whole line is opened to traffic, the driving distance from Liupanshui City to Zhaotong City will be shortened from the current 5 hours to 2 hours, which will improve the national and provincial highway network and promote regional economic development

 
As the tunnel construction environment is closed, there are many concealed works, the hidden dangers of project quality and safety are easy to be difficult to control, the engineering geological survey of tunnels in some areas and projects is unknown, the design depth is insufficient and other factors, resulting in the unsafe construction of the project

According to statistics, from 2009 to 2013, there were 33 tunnel construction accidents in China, resulting in 161 direct deaths and hundreds of millions of direct economic losses

In addition, it is very difficult to rescue after the accident, especially the collapse of the vault and the collapse of the door closing
According to incomplete investigation and statistics, the collapse of the door closing of the tunnel accounts for about 35% to 48% of the tunnel collapse
Therefore, it is very necessary to strengthen the safety and quality supervision of the tunnel and increase the safety measures in the tunnel construction accidents

At present, escape pipelines are very popular, so that some manufacturers do not have any technology to produce escape pipelines for the sake of interests
They do not know what raw materials are used, and they do not know whether they can pass the customs technically
These small manufacturers sell at low prices, which makes the market chaotic
Some middlemen supply such products to the project for the sake of interests, regardless of product quality
If the requirements on the project are not strict, they can muddle through, However, it is our tunnel construction personnel who are really injured
Their safety cannot be guaranteed
The potential danger of tunnel construction always exists
The truly qualified escape pipes are generally made of ultra-high molecular weight polyethylene
After the pipes are made, the price Zui is as low as more than 20 yuan a kilogram
Some manufacturers use PE to pretend to be ultra-high molecular weight escape pipes
Although it is cheap, the color looks the same, However, the performance of PE pipe is much worse than that of UHMWPE escape pipe in terms of safety, so don't worry about using it, so don't be greedy for cheap when buying

Performance parameters of new ultra-high escape pipeline
1
It is made of ultra-high molecular weight polyethylene, with an average molecular weight of about 3million

2
Yield strength σ 1=3
7gpa, elastic modulus e1=700mpa; Poisson's ratio ν 1=0
42。
3
The impact resistance is twice that of steel pipe, and it can withstand the strong impact of large stones without deformation

4
Hoop connection, clip on metal connection, chain connection and other connection methods are convenient for installation

Luoyang Guorun New Material Co
, Ltd
is a manufacturer of new ultra-high polymer tunnel escape pipes
It is located in the airport industrial agglomeration area of Luoyang, Henan Province
It is a listed enterprise, covering an area of more than 200 mu, and has 5 production lines of ultra-high polymer tunnel escape pipes, with high production efficiency
Luoyang Guorun new material took the lead in developing this new type of tunnel escape pipe in 2015, and applied for a patent for this product
The manufacturer is large-scale and powerful
The manufacturer ships directly, with low price and perfect after-sales service

Requirements and application of pipes for tunnel escape pipes
1
Ensure that the thickness of the tunnel escape pipe is not less than 10mm
2
The length of each tunnel escape pipe is 1 meter &mdash& mdash; 3 meters
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 should 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

Advantages of new tunnel escape pipeline:
1
The pipeline has good toughness and high impact strength
Tunnel escape pipe, the new escape pipe will instantly deform when impacted by strong external forces, absorb a large amount of impact energy, and then quickly restore its original shape, providing a reliable guarantee for the emergency rescue of highway tunnel construction escape;
2
Light weight
Tunnel escape pipe, the new escape pipe is convenient for disassembly and handling, and can be moved without the help of mechanical equipment in the narrow space of the tunnel
Light weight, convenient disassembly and handling;
3
High rigidity of pipe ring
It has good pressure resistance and is not easy to deform
When tunnel escape pipes and new escape pipes collapse in highway tunnel construction, the pressure bearing capacity and anti environmental damage capacity are far higher than ordinary pipes

  When the thin-walled circular tube is impacted by the high-energy block stone at the top of the tunnel, the overall bending deformation of the lower half of the structure is small, and the deformation is mainly local depression at the impact point

The safety escape pipeline produced by Luoyang Guorun New Material Technology Co
, Ltd
is made of new materials and special processes, and the color of the pipeline is a more eye-catching orange pipeline, which is more eye-catching in the tunnel
This material is light in weight, easy to disassemble and handle; The pipeline has good toughness, high impact strength, instantaneous deformation when impacted by strong external forces, absorbs a large amount of impact energy, and can quickly restore the original shape without fracture
It is the preferred material for the new ultra-high molecular tunnel escape pipe, which has eliminated the previous steel pipe
This new ultra-high molecular tunnel escape pipe has a smoother wall than the previous steel pipe, and the friction coefficient is only 1/6 of the new steel pipe, which greatly improves the efficiency and shortens the rescue time
