High-strength escape pipe convenient to socket and fix

Abstract

The invention relates to a high-strength escape pipe convenient to socket and fix. The high-strength escape pipe is characterized by comprising a plurality of unit pipe bodies which are in socket connection end to end, wherein each unit pipe body comprises an inner pipe body and an outer pipe body; each inner pipe body comprises a pipe body section, a socket head section and a plug section; the pipe wall of each pipe body section is of a hollow structure; each hollow structure is filled with foam; each pipe body section is coaxially sleeved with the corresponding outer pipe body; the space between the pipe body section of each outer pipe body and the pipe body section of the corresponding inner pipe body is also filled with foam; a plurality of connecting pieces are connected to the socket parts of the connected unit pipe bodies; each connecting piece comprises an arc-shaped gasket, a through connecting pipe and a connecting bolt; each through connecting pipe is coaxially inserted into the socket part of the corresponding unit pipe body; each arc-shaped gasket is attached to the outer surface of the socket head section at the socket part; and each connecting bolt penetrates through the corresponding arc-shaped gasket and is in threaded engagement connection with the corresponding through connecting pipe. The high-strength escape pipe is light in weight, good in compressive property and high in socket stability.

Description

technical field [0001] The invention belongs to the field of pipe materials, and relates to escape pipe technology, in particular to a high-strength escape pipe which is conveniently socketed and fixed. Background technique [0002] In the working environment of tunnels or mines, landslide accidents are very prone to occur. When a landslide accident occurs, the on-site personnel need to escape from the accident scene through the escape pipe, and the escape pipe is prone to deformation, bending and other problems during the accident, which makes the escape People are often unable to escape from the scene of the accident and reach the safe zone in time. [0003] Common escape pipes include metal pipes and cement pipes. Metal pipes are heavy, easy to rust after a long time, and have poor corrosion resistance. The cost of cement escape pipes is low, but they are heavy, have poor compression resistance, and low safety factor. During the construction process, the escape pipes are...
