  The qualification of tunnel escape pipes is complete, and the requirements for the setting of escape pipes are in stock
We Luoyang Zhongxiong Pipe Industry Co
, Ltd
specializes in the production of ultra-high molecular weight polyethylene tunnel escape pipes, with a diameter of φ 800mm*30mm、φ 860mm*30mm、φ 1066mm*33mm。 Each batch of delivery has been tested and verified by the internal quality control organization, and the delivery is qualified
The escape pipeline has long been supplied to railway, highway, subway, mine and other tunnel construction projects
Its good quality and high-quality service have been highly praised by customers

Material and setting requirements of escape pipe:
According to the results of repeated experiments and relevant theoretical data, the size of the tunnel escape pipe is not easy to be too small, it is easy to damage the escape pipe in case of collapse, and the size will increase the cost, which is not conducive to the transfer in construction
Combined with Hertz research results, the size of tunnel escape pipe is determined as 800mm outer diameter and 30mm wall thickness

φ 800*30、φ For 860*30 ultra-high polymer escape pipes, the length of pipe joints can be determined according to the site conditions
3M and 6m pipe joints with a wall thickness of 30mm can be selected
The pipe joints can be connected with metal hoops with a diameter greater than the diameter of the escape pipe or temporarily fixed with 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

Monitoring measurement and observation of tunnel escape pipeline:
1
monitoring and measurement mainly include vault subsidence and horizontal convergence
At present, ruler measurement and non ruler measurement are adopted
In order to ensure the accuracy of the measurement data and the convenience of operation, the large section tunnel should be measured without ruler

  2
when the tunnel is shallow buried, the monitoring network must be set on the surface and monitored
When the arch crown sinks or the horizontal convergence rate reaches 5mm/d or the accumulated displacement reaches 100mm, the construction shall be suspended, the causes shall be analyzed and the treatment measures shall be put forward
(these empirical data are very important)
When measuring with a ruler, the hook of the measuring point shall be made into a closed triangle to ensure no deformation and point contact
The buried point shall not be welded in the steel frame

3
monitoring measurement is to use special instruments and tools to observe the deformation and stress of surrounding rock and support structure and the relationship between them during tunnel construction, and evaluate their stability and safety, so as to verify and adjust the construction method and structural support parameters
It is the “ Eyes &rdquo 。 As an important part of the construction organization design, monitoring and measurement shall be incorporated into the construction process, which shall be in the charge of a specially assigned person, and a hierarchical management, information feedback and reporting system shall be established
Establish a risk early warning mechanism for daily deformation and cumulative deformation

Advantages of ultra-high molecular weight escape pipeline:
(1) Extremely high wear resistance, with ultra-high molecular weight of more than 2
5 million, small wear index, and wear resistance 6
6 times higher than that of general alloy steel
The service life of the pipeline is greatly improved
(2) Extremely high impact resistance
This product meets the GB1843 standard
The impact toughness value of this product is very high in the existing engineering plastics
(3) Corrosion resistance, this product can resist the erosion of strong chemicals
(4) Good self lubrication, good self lubrication, low friction coefficient, no adhesion and scaling on the surface
(5) Unique low temperature resistance
This product has excellent low temperature resistance and can work at -269 ℃ to 80 ℃ for a long time
(6) It is easy to install, the specific gravity is only one eighth of the steel pipe weight, and it is convenient to disassemble and handle
