Electromechanical pipeline structure for fabricated building

The electromechanical pipeline structure comprises prefabricated pipe joints, connecting beams, outer sleeves, inner sleeves and transmission assemblies, the two outer sleeves are moved back to back through the driving assemblies on the outer sleeves, then inner arc plates are made to turn to the inner arc surfaces of outer arc plates so as to open a hole channel, and in the hole channel opening process, the inner arc plates are turned to the inner arc surfaces of the outer arc plates so as to open the hole channel. The torsion chain rod of the transmission assembly enables the two inner sleeves to be separated from the pipe openings of the two prefabricated pipe joints and to be retracted into the outer sleeve, so that maintenance personnel can conveniently maintain facilities in the electromechanical pipeline, the later operation and maintenance efficiency of the electromechanical pipeline is improved, disassembly of the prefabricated pipe joints is avoided, and the operation and maintenance cost is reduced
