The technical scheme for solving the problems is as follows: a prestressed stay cable anchorage device with an elastic sealing cylinder comprises an anchor head and a sealing device which is connected between the anchor head and a cable body and consists of the sealing cylinder and a sealing lantern ring, wherein the sealing cylinder is the elastic sealing cylinder, and the elastic sealing cylinder is respectively connected with the anchor head and the sealing lantern ring in a threaded or flange connection mode.
The further technical scheme is as follows: the elastic sealing cylinder is an elastic sealing cylinder I, the elastic sealing cylinder I is a PE sealing cylinder made of PE materials or an HDPE sealing cylinder made of HDPE materials, threads I and threads II are arranged at two ends of the elastic sealing cylinder I respectively, one end of the elastic sealing cylinder I is connected with the anchor head through the threads I, the other end of the elastic sealing cylinder I is connected with the sealing lantern ring through the threads II, and the lantern ring is a PE sealing lantern ring or an HDPE sealing lantern ring.
The further technical scheme is as follows: the sealing cylinder is an elastic sealing cylinder II, an internal thread II is arranged at one end of the elastic sealing cylinder II, a hot melting flange is arranged at the joint of the elastic sealing cylinder II and the anchor head, the elastic sealing cylinder II is connected with the anchor head through a pressing ring and a bolt, and the other end of the elastic sealing cylinder II is connected with the sealing sleeve ring through the internal thread II.
The further technical scheme is as follows: the elastic sealing cylinder II is made of thermal shrinkage rubber or PE (polyethylene) material or HDPE (high-density polyethylene) material.
The elastic sealing cylinder II is a cylindrical elastic sealing cylinder II or a conical elastic sealing cylinder II.
Due to the adoption of the technical scheme, the prestressed inhaul cable anchorage device with the elastic sealing cylinder has the following beneficial effects:
the cable body and the anchorage of the prestressed inhaul cable are separated before installation and use, the cable body penetrates into the anchorage during installation, and the distribution of the cable body in an anchoring area is bent in part of practical application working conditions, so that the cable body is deflected to one side and is easy to scratch; the sealing cylinder of the prestressed inhaul cable anchorage device with the elastic sealing cylinder is made of an elastic new material, can adapt to bending angle production installation errors under various working condition environments, realizes dynamic sealing and has a damping and buffering effect; the construction quality is easily guaranteed, and construction tensioning accidents are avoided.
The technical features of a prestressed cable anchorage with an elastic sealing cylinder according to the present invention will be further described with reference to the accompanying drawings and embodiments.
