Prestress inhaul cable anchorage device with elastic sealing cylinder

Abstract

A prestress inhaul 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 composed of the elastic sealing cylinder and a sealing lantern ring, and the elastic sealing cylinder is an elastic sealing cylinder I or an elastic sealing cylinder II and is respectively connected with the anchor head and the sealing lantern ring in a threaded or flange connection mode. The elastic sealing cylinder I is a PE sealing cylinder made of a PE material or an HDPE sealing cylinder made of an HDPE material, the two ends of the elastic sealing cylinder I are provided with a thread I and a thread II respectively, the elastic sealing cylinder II is made of thermal shrinkage rubber or the PE material or the HDPE material, one end of the elastic sealing cylinder II is provided with an internal thread II, a hot melting flange is arranged at the joint of the elastic sealing cylinder II and the anchor head, and the elastic sealing cylinder II is connected with the anchor head 1 through a pressing ring and a bolt. Due to the fact that the sealing cylinder of the prestress inhaul cable anchorage device is elastic, the prestress inhaul cable anchorage device can adapt to automatic deviation correction of installation errors, dynamic sealing is achieved, damping and buffering effects are achieved, and construction quality is guaranteed.

Description

technical field [0001] The invention relates to a prestressed cable anchor, in particular to a prestressed cable anchor with an elastic sealing cylinder. Background technique [0002] The structure of the prestressed cable anchor is very long. It is composed of an anchor head and a sealing device composed of a sealing cylinder and a sealing collar. The sealing cylinder connected between the anchor head and the cable body plays the role of sealing, waterproofing, shock absorption and buffering. The sealing cylinder of the existing prestressed cable anchor head is made of steel pipe, which has no elasticity and is relatively long. There is a large error after installation, and it cannot adapt to the automatic deviation correction of the installation error. The sealing of the sealing cylinder is easily damaged, and the original There should be waterproof and shock-absorbing buffering effects. During the operation of bridges, etc., there is a danger of water seepage, which will ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a prestressed cable anchor with an elastic sealing cylinder. The sealing cylinder of the prestressed cable anchor with an elastic sealing cylinder is an elastic sealing cylinder made of a new elastic material. It solves the situation that the sealing cylinder made of the original steel pipe has no elasticity, cannot adapt to the automatic deviation correction of the installation error, and is easy to be damaged, solves the waterproof problem of the dynamic sealing of the prestressed cable anchorage, and provides a durable, safe and reliable use of the bridge cable new insurance
