What are the Precautions for Using Life Escape Pipe?

As a Life Escape Pipe Manufacturer, share with you. The ultra-high molecular weight polyethylene tunnel safe escape pipeline uses ultra-high molecular weight polyethylene pipeline. The impact escape index of the ultra-high molecular weight polyethylene tunnel safe escape pipeline is better than ordinary steel pipes, which ensures the safe escape of the ultra-high molecular weight polyethylene tunnel. The reliability of pipelines used in emergency rescue of highway tunnel construction.

Life Escape Pipe

The following introduces the precautions for the use of Life Escape Pipe.

1. The ultra-high-molecular-weight polyethylene escape pipe used for the escape channel is a pipe connection with a diameter slightly larger than the escape pipe. Each end is connected by 1m. It is temporarily fixed with rubber rings or wooden wedges. In order to ensure that the pipeline can withstand the pressure of the collapsed body, the material pipe used must ensure its pressure bearing capacity and the firmness of the joints, and can be used in the tunnel only after specific tests in the laboratory.

2. The construction site should have sufficient pipelines and connection materials according to the surrounding rock of the tunnel and the method of excavation and excavation. In addition to the entire section of the pipeline, at the same time, 1m, 2m, and 3m short-section pipes and adapters (external joints) 135 °) and so on.

3. Pipes can only be used after being processed. All units can be processed separately in accordance with the material and the actual situation on site. The connection is required to be simple, solid, tight and reliable, and temporary fixing measures must be done on the ground. The pipe mouth can be temporarily capped during construction. And easy to open and close. The cross section of the pipeline connection is as follows:

4. The escape pipeline is made of ultra-high molecular polyethylene escape pipe. The starting point is the newly constructed end of the second lining. The distance from the end of the second lining should not be greater than 5 meters. It is arranged from the lining working surface to within 20m from the excavation surface. In the proper position, the pipe is laid along the side of the initial support to the palm surface, and a working rope is reserved in the pipe to facilitate escape, rescue, communication and transmission of various items. The longitudinal connection of the socket steel pipe can adopt measures such as a chain to prevent the steel pipe from being washed out during collapse.

5. During the movement of the second-lined trolley in place, the escape pipeline should be dismantled section by section during temporary dismantling. One-time dismantling is strictly prohibited to ensure the effectiveness of the escape pipeline at any time.

6. As an emergency life-saving pipe, the escape tube should closely follow the palm surface, the distance between the end and the palm surface should not be greater than 5m, and an eye-catching tool box should be installed near the mouth of the tube. The emergency flashlight, adjustable wrench, hammer, and steel drill should be stored in the box And other emergency tools, it is convenient to open the escape pipe flange in emergency situations, open life-saving pipes, and deliver water and food in a timely manner.

7. The escape pipeline should be arranged as an extended step when it passes through the excavation steps. A 135 ° adapter can be installed to extend it. The overhead height and length of the pipeline should not affect the construction and facilitate the opening of the escape window.
