The invention discloses a tunnel escape pipeline and a construction method thereof, and relates to the technical field of
tunnel construction. The escape pipeline comprises a plurality of escape
pipe joints connected end to end, connecting assemblies, supporting seats and supply pipelines, wherein connecting sections are arranged at the two ends of each escape
pipe joint correspondingly, the connecting assemblies are arranged at the connecting sections and used for connecting every two adjacent escape
pipe joints, the supporting seats are arranged at the bottoms of the connecting assemblies and used for supporting the connecting assemblies and the escape pipe joints, adjustable moving devices are arranged on the two sides, in the extending direction of the escape pipe joints, of the supporting seats, the supply pipelines are installed on the supporting seats and arranged in the extending direction of the escape pipe joints,
branch pipelines communicating with the supply pipelines are arranged in the supporting seats, and the
branch pipelines communicate with the escape pipe joints and are used for providing water and air for escape personnel. By implementing the technical scheme,
oxygen and water can be supplied to the escape personnel in a construction accident in a tunnel at a lower cost, precious rescue time is won, and a dangerous case is prevented from spreading to cause a secondary accident.
