Waterproof and anti-corrosion sealing device for bridge cable joint

DING YANG

The invention relates to the field of bridge protection, in particular to a waterproof and anti-corrosion sealing device for a bridge inhaul cable joint. According to the waterproof and anti-corrosion sealing device for the bridge inhaul cable connecting position, sealing treatment can be conducted on the inhaul cable connecting position to prevent the connecting position of the inhaul cable from being corroded when external force acts on the inhaul cable. A waterproof and anti-corrosion sealing device for a bridge inhaul cable joint comprises a guide pipe, a sealing air bag, a sealing bush, a leakage-proof mechanism and the like. A sealing air bag is arranged on the outer side of the inhaul cable in the guide pipe in a wrapping mode, a sealing bush is arranged on the outer side of the sealing air bag in a wrapping mode, and the leakage-proof mechanism is further connected between the upper portion of the outer side of the guide pipe and the inhaul cable. And the leakage-proof mechanism is arranged, so that the device can seal the connecting part of the inhaul cable while being matched with the displacement of the inhaul cable so as to prevent rainwater from leaking into the connecting part of the inhaul cable, namely the corrosion of the connecting part of the inhaul cable due to water leakage caused by the displacement of the inhaul cable due to the influence of external factors is prevented.

本发明涉及桥梁防护领域，尤其涉及一种桥梁拉索连接处防水防腐蚀密封装置。本发明提供一种在有外力作用在拉索上也能对拉索连接处密封处理防止拉索的连接处腐蚀的桥梁拉索连接处防水防腐蚀密封装置。一种桥梁拉索连接处防水防腐蚀密封装置，包括导管、密封气囊、密封衬套和防漏机构等；在导管内部的拉索外侧包设有密封气囊，密封气囊的外侧包设有密封衬套，还包括防漏机构，导管外侧上部和拉索之间还连接有防漏机构。防漏机构的设置使本装置在配合拉索位移的同时还能够对拉索连接处进行封闭处理，以防止雨水漏进拉索连接处，即防止拉索连接处因拉索受外界因素影响产生位移导致漏水而产生拉索连接处的腐蚀。
