Device for conducting electric chlorine removal on suspender of suspender arch bridge

Abstract

The invention discloses a device for conducting electric chlorine removal on a suspender of a suspender arch bridge. The device comprises a casing internally provided with a plurality of steel tendons. The upper ends of the multiple steel tendons are fixed to arch ribs. The lower ends of the multiple steel tendons penetrate through a bridge deck slab beam steel bottom end plate and are fixed to the steel bottom end plate. Rustproof grease is arranged in the casing. The part, at the suspender, of a bridge deck slab is provided with a pit. No casing exists outside the part, in the pit, of the steel tendons. A first seal plate preventing leakage of the rustproof grease in the casing is arranged at the part, on the top face of the pit, of the casing. The parts, in the pit, of the steel tendonsare provided with a cake-shaped liquid seepage body, and the cake-shaped liquid seepage body is made of hydrophilic materials and soaked with electrolyte solution. At least two stainless steel platesare arranged in the pit. The outer sides of the stainless steel plates are provided with tight abutting devices through which the stainless steel plates tightly abut against the peripheral surface ofthe cake-shaped liquid seepage body soaked with the electrolyte solution. The stainless steel plates are connected with the anode of a direct-current power source through wires. The cathode of the direct-current power source is connected with the steel bottom end plate of the suspender through a wire. Through the device for conducting electric chlorine removal, chloride ions on the steel tendonsof the suspender can be removed effectively.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a device for removing chlorine by electromigration on a suspender of a suspender arch bridge. Background technique [0002] One end of the suspender of the prior art suspender arch bridge is fixed such as passing through the top steel structure for riveting or screwing or anchoring on the arch rib, and the other end passes through the bridge deck and the beam supporting the bridge deck and the bottom steel structure and is connected to the bottom. The end steel structure is fixed such as riveted or screwed or anchored. The structure of the boom is generally a non-metallic casing with multiple steel wire bundles, the bottom of the casing is generally sealed, and the entire casing is filled with anti-rust grease from bottom to top. However, in practical applications, the grease in the casing will inevitably leak, and the evaporated water will inevitably leak from the t...
