Corrugated pipe locating and sealing method in concrete segment precast assembling
The invention discloses a corrugated pipe locating and sealing method in concrete segment precast assembling. In the segment precast stage, when a corrugated pipe of a prior segment is set, a ring core is connected to the back end of the corrugated pipe, a barrel-shaped portion is sleeved with a locating ring, the locating ring and the barrel-shaped portion are matched tightly, the barrel-shaped portion penetrates through a limiting hole in a back end template, and the locating ring and the limiting hole are closely matched; when the corrugated pipe of a post segment is arranged, a buckling cap is connected to the front end of the corrugated pipe, the buckling cap is buckled on the barrel-shaped portion of the prior segment, and the bucking cap and the locating ring of the prior segment are tightly matched; in the segment assembling stage, the barrel-shaped portion of the prior segment is sleeved with a pushing ring and a sealing ring, the bucking cap of the post segment is bucked on the barrel-shaped portion, so the sealing ring can be pushed by the pushing ring to slide along a circular cone section and a second cylinder section, expand and deform to close a space between the bucking cap and the second cylinder section. According to the corrugated pipe locating and sealing method in concrete segment precast assembling, accurate locating of the corrugated pipes is achieved, and the sealing effect is good.
