The longitudinal section of the groove is approximately in an inwards concave semicircular shape; the longitudinal section of each convex strip is approximately in a convex semicircle shape.

The raised lines are metal sheets or hard plastic sheets inserted in the relative upper end faces of the smoke pipeline body.

A blind hole is formed in one side wall of the smoke exhaust pipeline body from outside to inside.

The wall thickness of the inner wall of the blind hole is 1/3-1/2 of the wall thickness of the side wall of the blind hole.

And reinforcing ribs integrated with the smoke exhaust pipeline body are arranged at the inner corners of the smoke exhaust pipeline body.

The height of the smoke exhaust pipeline body is 250-800 mm.

One side wall of the smoke exhaust pipeline body is provided with a through hole.

After the structure is adopted, the grooves are annularly arranged on the lower end faces of the smoke exhaust pipeline bodies, the convex strips arranged corresponding to the grooves are annularly arranged on the upper end faces of the smoke exhaust pipeline bodies, in the construction and installation process, the upper smoke exhaust pipeline and the lower smoke exhaust pipeline can be mutually butted and inserted together through the convex strips and the grooves which are correspondingly arranged on the upper end faces and the lower end faces of the smoke exhaust pipeline bodies, and the direct butt joint parts of the upper smoke exhaust pipeline and the lower smoke exhaust pipeline can be positioned at any position of a floor, so that the height of the smoke exhaust pipeline can be uniformly manufactured no matter the height of the floor is high or low, the height of a single smoke exhaust pipeline is effectively reduced, the mechanical processing is convenient, the production efficiency is improved, the product quality is ensured, and the smoke exhaust pipeline is not easy to break in the hoisting and transportation processes; simultaneously because set up sand grip and recess and correspond grafting structure on the relative lower extreme of exhaust gas pipeline body self, exhaust gas pipeline butt joint position after the installation is difficult for the dislocation, and butt joint position leakproofness is good, and during the use, the exhaust gas pipeline can not appear and play cigarette, the taint of smell phenomenon, also can not appear falling the cigarette phenomenon.
