[0002] Application number CN 116817046 A discloses "a prefabricated direct-buried insulated pipe that is easy to connect". When two adjacent sections of direct-buried insulated pipes are connected, the first connector provided on one section is first inserted into the second connector provided on the other section to achieve pre-fixation of the two sections of direct-buried insulated pipes, which is convenient for subsequent bolt fixation. Simple docking of the two sections of direct-buried insulated pipes is achieved, reducing the difficulty of subsequent fixation. After the insulation sleeve is put on the conveying pipe, the limiting insert is inserted into the conveying pipe to achieve positioning of the insulation layer, avoiding the insulation layer protruding from the conveying pipe when fixing, and the positioning of the insulation layer can be quickly achieved. However, the device does not have a sealing ring at the pipe connection, which will cause the insulation pipe to leak when used; and when using bolts to fix the connection between the two insulated pipes, the number of bolts is large and tightening is time-consuming and labor-intensive, and the position angle of the bolts is close to the pipe, which increases the time cost of construction.
