The utility model relates to a pipe piece socket type connecting structure, which aims to reduce the weakening of the connecting structure to a pipe piece structure to the maximum extent, greatly improve the convenience and timeliness of pipe piece installation and effectively avoid the risk that a connecting component falls off in the tunnel operation period. The front segment is provided with ahand hole and a socket hole which are connected through a straight duct, and the rear segment is provided with a mounting hole corresponding to the socket hole. The assembly type component comprises an embedded threaded sleeve, a straight screw, a long nut and a gasket. After the pre-embedded threaded sleeve is pre-embedded and fixed in the mounting hole, the front end of the straight screw is inthreaded connection with the pre-embedded threaded sleeve, a body of the straight screw penetrates through the mounting hole to enter the socket hole, the rear end of the straight screw is in threadedconnection with the long nut penetrating through the straight hole channel from the hand hole to enter the socket hole, and the rear end of the long nut acts on the wall of the hand hole through thegasket. And guide sleeves nested on the long screws are arranged in the mounting holes and the socket holes, and the peripheries of the guide sleeves are in contact with the hole walls of the mountingholes and the socket holes, so that the guide sleeves play a role in guiding and positioning the assembly of the front-sequence duct pieces and the rear-sequence duct pieces.
