As a further description of the above technical solution:

The bottom of the triangular support block is welded with a conduit bottom template.

In the utility model, first, a layer of ceramic liner is added inside the conduit for passing through the building, so that on the premise of ensuring the strength of the conduit, ceramics have the advantage of strong high temperature resistance, and ensure the corrosion resistance of the conduit ; Secondly, the conduit is provided with a buffer interlayer between the metal layer and the ceramic layer, which can effectively protect the ceramic layer and prevent the impact of the metal layer from being directly transmitted to the ceramic layer to cause the ceramic layer to break. In addition, the two ends of the buffer interlayer They are all equipped with convex edges. When connecting with other conduits or parts, the filling of the convex edges can greatly improve the sealing of the connection parts and achieve the purpose of seamlessness; finally, the connection parts of the conduits and conduits are fixed by installing a The movable connecting rings are connected by springs between the connecting rings. When connecting the conduits, the bolts pass through the through holes on the movable connecting rings to connect with other conduits, which can play a good buffering role, protect the connecting parts, and at the same time make more closely connected.
