Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.

A high-strength escape pipe with good impact resistance comprises an inner pipe body 3 and an outer pipe body 1, wherein the inner pipe body comprises a pipe body section, one end of the pipe body section extends to form a socket section 9, and the other end of the pipe body section extends to form a plug section 7; the inner diameter of the socket section is larger than the outer diameter of the plug section; the outer surface of the pipe body section is integrally provided with a thread groove, reinforcing ribs 6 are fixedly arranged in the thread groove, vertical grooves are axially formed in the inner surface of the inner pipe body at intervals, rubber strips 4 are filled in the vertical grooves, a luminous layer 5 is arranged on the surfaces of the rubber strips, the thread groove and the vertical grooves are respectively arranged on the outer side and the inner side of the inner pipe body in a staggered mode, a honeycomb structure is formed in the cross section of the pipe wall of the inner pipe body, the integral gravity of a pipeline is reduced, the strength of the integral pipe wall is greatly improved, the outer pipe body is coaxially sleeved outside the pipe body section, a buffer layer 2 formed by foam is filled between the outer pipe body and the inner pipe body, the foam is prepared by mixing a foaming agent A and a foaming agent B, and the reinforcing ribs are better fixed on the surface of the inner pipe body.

The vertical inslot is filled with the rubber strip, because the rubber strip surface is smooth to have lubrication action and certain intensity, fills the rubber strip for intraductal inner wall of fleing is smooth, is convenient for flee the climbing, and the rubber strip still has certain elasticity moreover, can increase the elasticity of body self, prolongs its life.

The utility model discloses in the implementation, rubber strip surface coating has one deck luminescent material (can be in the dark self-luminous), forms the luminescent layer on rubber strip top layer to solved and to have unable the problem of finding the pipeline mouth of fleing when the tunnel collapses, still played the effect that the guidance of fleing.
