Embodiment Construction

[0035] The invention can overcome the unpredictable and unmonitorable problems of unbonded prestressed anchorage corrosion, prevent corrosion through intelligent monitoring, and provide simple and direct maintenance guidance for maintenance personnel.

[0036] Further description will be made below in conjunction with the accompanying drawings.

[0037] See figure 1 , the non-bonded prestressed anchoring intelligent anticorrosion structure of the suspension bridge of the present invention is used in the prestressed cable anticorrosion of the suspension bridge. It is composed of prestressed cable 6, prestressed pipeline 7, valve 3, monitoring component 4, pipeline network 2, air source 1 and sealing cover 5.

[0038] Specifically, the air source 1 of the present invention is clean dry air or an inert gas, which may be clean dry air or nitrogen provided by a dehumidifier or a nitrogen generator. An air source 1 is connected to a plurality of duct networks 2 .

[0039] One end...

Abstract

A suspension bridge unbonded prestressed anchorage corrosion resistant structure comprises an air source and a plurality of prestressed pipelines, wherein the air source is clean dry air or inert gas and is connected with a plurality of pipeline networks; one end of each prestressed pipeline is provided with an air inlet, and the other end of each prestressed pipeline is provided with an air outlet; a seal cover is arranged at each air inlet and each air outlet; an air hole is formed in each seal cover and connected with a sealed monitoring component; each monitoring component is connected with the corresponding pipeline network; a valve is arranged at each monitoring component. The invention also discloses a suspension bridge unbonded prestressed anchorage corrosion resistant method. The suspension bridge unbonded prestressed anchorage corrosion resistant method and the suspension bridge unbonded prestressed anchorage corrosion resistant structure have the advantages that the unbonded prestressed anchorage corrosion resistant ability is improved, the life is prolonged, detection is convenient, and maintenance costs are lowered.

Description

technical field [0001] The invention relates to the technical field of bridge anti-corrosion, in particular to a non-bonded prestressed anchor anti-corrosion structure of a suspension bridge. [0002] The invention also relates to a non-bonded prestressed anchoring and anticorrosion method for the suspension bridge. Background technique [0003] Corrosion and detection of unbonded prestressed anchorage of suspension bridges is a difficult problem. Although the prestressed cables can be replaced, the replacement is difficult and expensive. Strengthening the anticorrosion of prestressed cables is of great significance. [0004] Unbonded prestressed anchorage usually adopts the way of pouring grease to corrode the prestressed cable, but in actual use, it is found that the prestressed cable still has a large corrosion threat. The main reason is that the prestressed pipeline leaks, the grease in the pipeline leaks, and the anchor The ingot water damage is serious, which threaten...
