Tunnel Escape Pipe Installation:
1. The pipes used for the escape passage can be steel pipes with a diameter of φ600 to φ800mm and a wall thickness of no less than 6mm, with a recommended length of 5m per section.
2. The starting point of the escape passage should be at the newly constructed arch closure at the loop end, with a distance from the face not exceeding 20m. A working rope should be reserved inside the pipe to facilitate escape in case of emergencies.
3. The escape pipes are connected using flange connections.
4. Each division and tunnel team should promptly purchase materials and actively organize the installation of pipes upon receiving this notice, while also formulating specific implementation methods and promotion plans based on their actual conditions to ensure the orderly installation of the rescue pipes and the construction of the tunnel.

Performance of Tunnel Escape Pipes:
1. The highway tunnel escape pipes and new impact-resistant escape pipes have good corrosion resistance and impact resistance even under low-temperature conditions.
2. Made with our company's unique formula, the highway tunnel escape pipes and new impact-resistant escape pipes have high corrosion reliability.
3. Reasonably designed and easy to install. The pipe ends are equipped with connection components and lifting rings to ensure easy installation and lifting.
4. Low material costs save procurement costs for engineering projects.
5. The highway tunnel escape pipes and new impact-resistant escape pipes have strong corrosion resistance, are easy to construct, and have a service life of 30-50 years.
6. The bottom layer of the tunnel construction escape pipe contacts with the steel pipe surface is coated with epoxy powder corrosion-resistant coating, and the outer layer is resin anti-rust paint. The inner wall is smooth, allowing for quick escape during incidents, minimizing secondary injuries.
7. Our highway tunnel escape pipes and new impact-resistant escape pipes are recognized for their effective use and performance of the pipe corrosion-resistant coating, and have been applied in many projects.
Layout Requirements for Tunnel Escape Pipe Lines:
1. During the movement and positioning of the secondary lining carriage, the escape pipes should be disassembled section by section temporarily; it is strictly forbidden to dismantle all at once to ensure the functionality of the escape pipes at all times.
2. When the highway tunnel escape pipes and new impact-resistant escape pipes pass through the excavation steps, they should be arranged according to the steps and installed with 135° transition joints, ensuring that the escape pipes are level, dry, and smooth, and must not be used for purposes other than emergency escape.
3. The length of the highway tunnel escape pipes and new impact-resistant escape pipes should be 100m.
4. The pipes used for the escape passage should be φ800mm steel pipes or other impact-resistant pipe materials. The length of each pipe section should be 15m, with a wall thickness of 7mm. Connections between pipe sections can use casing with a diameter greater than that of the escape pipe, with each end connected by 1m and temporarily fixed with rubber rings or wooden wedges. To ensure the pipes can withstand the pressure from collapse materials, the material used for the pipes must ensure pressure-bearing capacity and the firmness of the joints, and must be tested in a laboratory before being used in the tunnel.
5. The construction site should prepare sufficient pipes and connection materials based on the surrounding rock conditions and excavation methods of the tunnel. In addition to whole pipe sections, short pipe sections of 1m, 2m, and 3m should also be prepared.
6. Highway tunnel escape pipes and new impact-resistant escape pipes should be processed according to the material and actual site conditions, ensuring simple, firm, and reliable connections. Temporary fixing measures should be implemented on the ground, and temporary sealing caps can be added to the pipe openings during construction, making them easy to open and close.
7. Highway tunnel escape pipes and new impact-resistant escape pipes should use φ800mm steel pipes or other impact-resistant pipe materials. The starting point should be at the constructed secondary lining end, with a distance from the secondary lining end not exceeding 5m, laid from the lining working face to an appropriate position within 20m of the excavation face. The pipes should be laid along one side of the initial support towards the face, with a working rope reserved inside for easy escape, rescue, communication, and the transmission of various items. Longitudinal connections of steel pipes can use chains or similar measures to prevent the pipes from being dislodged during a collapse.
