Movable tunnel escape pipe

A movable tunnel escape pipe is used for escape when an accident occurs in a tunnel, belongs to the technical field of escape pipe manufacturing, and comprises a pipe unit, a framework is arranged on the peripheral surface of the pipe unit, the cross section of the framework is a square concentric with the cross section of the pipe unit, and the outer diameter of the pipe unit is equal to the width of the inner surface of the framework. According to the movable tunnel escape pipe, the mode that the framework is installed on the outer circumference of the pipe unit and the wheels are installed on the framework through the folding legs is adopted, the movable tunnel escape pipe is designed, and the problem that the installation efficiency of an escape pipeline is low due to the fact that carrying and installation of an existing tunnel escape pipe are basically conducted manually is solved. 一种可移动式隧道逃身管，用于在隧道内发生事故时逃身，属于逃身管道制造技术领域，包括管单元，管单元的外周面上设有骨架，骨架的横截面为与管单元的横截面同心的正方形，管单元的外径等于骨架的内表面的宽度，骨架上通过折叠腿设有轮子，本实用新型采用在管单元的
