As shown in fig. 1 and 3, the pipe body 1 is provided with three sets of sealing mechanisms 3 for sealing the grouting holes 131. The sealing mechanisms 3 are arranged in an array along the axial direction of the pipe body 1, and each sealing mechanism 3 corresponds to each grouting hole group 13 one by one. The sealing mechanism 3 comprises a first half ring block 31 and a second half ring block 32, the first half ring block 31 and the second half ring block 32 being connected by two locking mechanisms 4. The two locking mechanisms 4 are respectively provided at the abutting portions of the first half ring block 31 and the second half ring block 32.
As shown in fig. 2 and 4, a slot 321 is formed at one end of the second half ring block 32 facing the first half ring block 31, and an insertion hole 322 communicating with the slot 321 is formed on an outer wall of the second half ring block 32. The locking mechanism 4 comprises an inserting block 41 arranged on the first semi-ring block 31, an operating groove 411 is formed in one end, away from the axis of the first semi-ring block 31, of the inserting block 41, an operating block 42 and a spring 43 are arranged in the operating groove 411, two ends of the spring 43 are respectively abutted to one end, away from the opening, of the operating groove 411 and the operating block 42, and the first semi-ring block 31 and the second semi-ring block 32 are made of elastic materials. When the operation block 42 is inserted into the insertion block 41, the inner walls of the first half ring block 31 and the second half ring block 32 are attached to the outer circumferential surface of the pipe body 1.
As shown in fig. 2 and 4, the inner diameters of the first half ring block 31 and the second half ring block 32 are the same as the outer diameter of the movable ring groove 12, two ends of the first half ring block 31 along the axial direction are respectively attached to two ends of the movable ring groove 12 along the axial line of the pipe body 1, and two ends of the second half ring block 32 along the axial direction are respectively attached to two ends of the movable ring groove 12 along the axial line of the pipe body 1.
