摘要
Disclosed are a composite anchoring body, a pipeline connection device using the anchoring body, and a method for installing the same. An elastic body in the composite anchoring body is a straight strip-shaped polyhedron with a wide bottom and a narrow top. The bottom, the left end and the right end of the elastic body are all plane and the bottom is isosceles trapezoid. The top is a curve formed by a zigzag connection between planes. A number of racks are embedded at intervals in the length L direction of the elastic body, and the tooth crest of the saw teeth of the rack is parallel to the long sides of all planes forming the curved face. A horizontal plane of the elastic body is provided with a plurality of yielding portions uniformly distributed in the length L direction, and one rack is adjacent to at least one of the yielding portions in the width W direction of the elastic body. After an annular anchoring body formed by connecting at least one of the composite anchoring bodies end to end is put into an anchoring chamber of a socket of a pipeline connection device, the saw teeth are engaged with an outer wall of a spigot. The composite anchoring body and the pipeline connection device have the advantages of simple manufacture, convenient use, and good anchoring effect and are adapted to pipes with different diameters. The method for installing the pipeline connection device is simple to operate and high efficient.
