Escape pipeline is praised as (life pipeline) in Tunnel Engineering

  Escape pipeline is praised as (life pipeline) in tunnel engineering
The gradual development of highway tunnel engineering has higher and higher requirements for tunnel engineering construction technology, especially for super long tunnels
The engineering construction of these tunnels has technical difficulties such as thick overburden, complex geological conditions and poor construction conditions
In addition, the safety of construction personnel must be ensured during tunnel engineering
After many years, there are better solutions for tunnel collapse
If the time of tunnel collapse cannot be controlled during tunnel construction, the danger of construction personnel can be minimized! Zhongxiong escape pipe is specialized in the production of tunnel escape pipes
The comprehensive performance of tunnel escape pipes is very different from that of steel pipes
In the past, we often used steel pipes, but compared with UHMWPE escape pipes, steel pipes are inferior

The materials of UHMWPE escape pipes of Zhongxiong pipe industry are compared with those of steel pipes and glass fibers:
1
The ultra-high molecular weight escape pipeline of Zhongxiong pipe industry is a linear thermoplastic engineering plastic with an average molecular weight of more than (2
5) million, which is composed of polyethylene and butadiene monomers under the action of catalyst
The specification of the new light escape pipe produced by our company is φ 800*30mm, each section is 3M long and weighs 69
7kg per meter (steel pipe weighs 210kg per meter)

2
Steel pipe material, steel escape pipe
The transportation cost of steel pipe is relatively high, time-consuming, easy to deform, corrosion resistance and poor wear resistance
It is not recommended to use
Specification of steel escape pipe: φ 820*10mm,φ 1020*10mm,φ 1120*10mm。
3
Glass fiber material, 630*14mm in specification
As the cost performance is not as good as the above two, UHMWPE escape pipes are commonly used in the market

Outer diameter of tunnel escape pipe φ 800mm, the length of the pipe joint shall be determined according to the site engineering conditions: 3M and 6m long pipe joints, with a wall thickness of 30mm, and the pipe joints can be connected by metal band hoops with a diameter greater than the diameter of the escape pipe or temporarily fixed by bolts
In order to ensure that the pipeline bears the pressure of the collapsed body, the pressure bearing capacity and the firmness of the connector of the adopted materials and pipes must be ensured, and they can only be used in the tunnel after specific tests in the laboratory
The construction site shall prepare sufficient pipes and connecting materials according to the surrounding rock of the tunnel, the excavation method, etc
in addition to the entire section of pipes, it shall also prepare sufficient 1m, 2M and 3M short-term pipes and adapters After being processed and used, the tunnel escape pipe is processed separately in combination with the material and the actual situation on site
The connection is simple, firm, tight and reliable
Temporary fixing measures are taken on the ground
The pipe orifice can be temporarily covered during construction, and it is easy to open and close

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 construction process of tunnel construction support, and it is strictly forbidden to lag behind the support and exceed the safety step

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

5
in terms of tunnel blasting, 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
