The figure illustrates a case where the pipe body 1 is two, but is not limited thereto.

Referring to fig. 2, the external sealing connection assembly 10 includes a sliding cylinder 13 and an elastic sealing ring 12 sleeved on each pipe body 1, the sliding cylinder 13 on each pipe body 1 can slide relative to the pipe body 1, and the elastic sealing ring 12 on each pipe body 1 is tightly attached to the pipe body 1. The sliding cylinders 13 are sleeved outside the elastic sealing rings 12, one ends of the two sliding cylinders 13, which are away from each other, are connected with blocking edges 131 perpendicular to the pipe body 1, and the two elastic sealing rings 12 are located between the two blocking edges 131. The splice is also sleeved with a shielding ring 11 capable of sliding relative to the two pipe bodies 1, external threads are arranged at two ends of the shielding ring 11, and internal threads are arranged on the inner wall of a sliding cylinder 13 on each pipe body 1. Two sliding cylinders 13 are respectively used for being connected with two ends of the shielding ring 11 in a threaded manner.

When the pipe gallery is laid underground, the opposite ends of the two pipe bodies 1 are arranged in a cantilever manner, namely, the lower surfaces of the opposite ends are hollowed out so as to be convenient for installing the external sealing connection assembly 10, and the hollowed-out parts are filled after the external sealing connection assembly 10 is installed. The cantilever end of one pipe body 1 is provided with an annular inserting groove, and the cantilever end of the other pipe body 1 is provided with an annular inserting part.

Specifically, the elastic sealing rings 12 are tightly sleeved on the two pipe bodies 1, the sliding cylinders 13 are sleeved on the two pipe bodies, the cantilever end of one pipe body 1 is sleeved with the shielding ring 11, the annular inserting part on the cantilever end of the other pipe body 1 is inserted into the shielding ring 11 and extends into the annular inserting groove of the other pipe body 1, and the splicing is completed.
