Abstract

The utility model discloses a prefabricated finished product wall feed-through pipe assembly of a gas pipeline, which comprises a wall feed-through sleeve, a gas lead-in pipe, a connecting part and the like, and relates to the technical field of gas transformation, the prefabricated finished product wall feed-through pipe assembly comprises a gas pipe body, the gas pipe body is sleeved with the wall feed-through sleeve installed in a wall, and the wall feed-through sleeve is sleeved with the gas lead-in pipe. A centering ring is arranged between the gas pipe body and the wall bushing, structural adhesive is filled between the centering ring and the gas pipe body, and polystyrene foam is filled between the gas pipe body and the wall bushing. According to the utility model, the link of on-site processing of the prefabricated member is omitted, the working efficiency is improved, the wall bushing has a stronger supporting effect, the wall bushing can be better protected from being extruded by a wall body, the problem of deviation between estimated material consumption and actual use amount is solved, the workload of workers in the overhead working process is reduced, and the working efficiency is improved. And meanwhile, good safety performance and corrosion resistance are achieved in actual use.
