After a section of pipe body is assembled, the outer wall of the pipe body is cleaned smoothly, and then a layer of graphene inorganic waterproof anticorrosive paint with the thickness of 1-1.5mm is sprayed on the outer wall of the assembled pipe body in time by manually matching with a mechanical long rod nozzle.

According to the length processing requirement of the expansion joint designed by the pipe gallery, the spliced pipe body is generally 20-30m, reinforcing ribs are penetrated into holes in the longitudinal direction, reinforcing steel bars are embedded into the embedded rib grooves and the annular grooves, and the joint is reinforced by electric welding; the head and the tail of the reinforcing rib can be provided with threads, the reinforcing rib is mechanically pulled, and after the screw cap is screwed up, the screw cap is welded firmly by electric welding. The reinforcing steel bars can be arranged in the blocks or the steel fibers are added in the formula during the production of the inner and outer arc mortise and tenon building blocks, so that the procedure of adding reinforcing steel bars during the later assembly is avoided. All welding spots are painted and sealed by graphene inorganic waterproof and anticorrosive paint.

After the integral pipe gallery is assembled, an annular drainage groove is formed on the outer surface of the pipe gallery, so that the sewage overflowed from the pipe can flow into a sewage drain groove of a fence hole cover plate arranged below the central line of the pipe gallery. The concrete block pier of fixed piping lane is equipped with to piping lane both sides, is equipped with the fender soil bank between mound and mound to prevent that the time owe silt and block the sewer ditch, implement the protection to piping lane barrel from another angle.

The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements can be made to the technical scheme of the utility model without departing from the design concept of the utility model, and the modifications and improvements fall into the novel protection scope of the utility model.
