Abstract

The invention discloses a parallel steel strand inhaul cable embedded pipe opening sealing structure and method. The sealing structure comprises an outer sheath pipe, a PE sheath steel strand, a waterproof cover, a cable hoop, a sealing layer, a damping device and an embedded pipe, one end of the waterproof cover is connected with the sheath pipe in a sleeved mode, and the other end of the waterproof cover is connected with the embedded pipe opening in a sleeved mode; the PE sheath steel strand sequentially penetrates through the embedded pipe, the waterproof cover and the sheath pipe, the sealing layer is arranged at a pipe opening of the embedded pipe, the gap between the inner side of the embedded pipe and the PE sheath steel strand is filled with the sealing layer, and the cable hoop is arranged above the sealing layer and used for hooping the PE sheath steel strand. And the damping device is arranged between the inner side of the embedded pipe below the sealing layer and the PE sheath steel strand. The problem that condensate water of the parallel steel strand inhaul cable enters an anchor head area can be effectively solved, the problem that water enters the inhaul cable when an outer protection layer loses efficacy is also solved, and a multi-layer protection system of an anchoring area is formed.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a sealing structure and method for a nozzle opening of a parallel steel strand cable pre-embedded pipe. Background technique [0002] According to the structure of the free section, carbon steel cables are mainly divided into: parallel steel strand cables, steel strand finished cables, and steel wire finished cables. The finished cable has a regular shape, and the seal between the cable and the embedded pipe is easier to realize. There are also some patents related to the sealing of the steel strand cable embedded pipe nozzle in the prior art, such as: [0003] Chinese patent application CN104695327A discloses a sealing structure of embedded pipes at the ends of stay cables and slings, including embedded pipes that are sheathed on the outer circumference of the cables at the beam ends, and there is an annular gap between the embedded pipes and the cables , the front end of the p...
