At the construction site, direct assembly is carried out. By hoisting the first separation pipe body 1 directly above the second separation pipe body 2, the splicing of the pipe bodies of the first separation pipe body 1 and the second separation pipe body 2 is completed through the insertion and locking of the mating connection through hole 4 and the extending mating pin column 3.
