Novel stay cable end waterproof sealing structure
The invention relates to a novel stay cable end waterproof sealing structure matched and mounted with a connecting cylinder of an anchor device; the novel stay cable end waterproof sealing structure comprises an elastic seal ring, a seal press ring, and a seal cover; the seal press ring is arranged in a connecting cylinder port and exposed outside the connecting cylinder; an inner end face, opposite to the seal press ring, of the inner wall of the connecting cylinder is provided with an extrusion surface; the elastic seal ring is arranged between the inner end face of the seal press ring and the extrusion surface, and deformed by the extrusion surface so as to attach to the outer wall of the stay cable; the seal cover is arranged in the front end of the connecting cylinder, has a Huff structure, the front portion of the seal cover makes contact with the outer wall of the stay cable, and the corresponding contact surface is provided with the seal ring; the rear portion of the seal cover makes contact with the seal press ring or the connecting cylinder, and the corresponding contact surface is provided with a seal bar. The stay cable end, i.e., a boundary between the anchor device and a PE cable body is sealed; the novel stay cable end waterproof sealing structure can replace a conventional thermal contraction sleeve, is excellent in assembly rigidness, long in life, and more durable.
