Anti-theft telescopic integral discharge current device

Abstract

The invention discloses an anti-theft expansion integral current drainage device which comprises a current drainage strip arranged in a ballast bed and an infilling board arranged in an expansion joint, wherein the current drainage strip is welded with a metal board, a testing terminal is arranged on the metal board which is connected with wires through connecting points, and an expansion current drainage device body which is located on the expansion joint is arranged between the wires. The expansion current drainage device body comprises a sealing cover and an expansion device which is arranged in the sealing cover and is connected with the wires. The expansion device is connected with a first fixer and a second fixer through the wires. According to the anti-theft expansion integral current drainage device, the metal board is copper-cladded or alumetized and connected with the wires, the integral connection can meet expansion quantity of the expansion joint, construction is convenient, easy and fast, mechanical splice does not exist, the whole device is buried by concrete and is not exposed, and the anti-theft expansion integral current drainage device is firm, free of loss, strong in electric conduction, low in resistance, anti-theft, not prone to abrasion, free of maintenance, long in service life, labor-saving, material-saving and cost-saving. The expansion integral current drainage device can effectively meet the expansion quantity of the expansion joint, and ensure project quality and construction schedule of a stray current drainage system.

Description

technical field [0001] The invention is applicable to stray current drainage systems for expansion joints of various types of traffic, railways, bridges, tracks, and tunnels, and is specifically an anti-theft telescopic integral current drainage device. Background technique [0002] At present, all kinds of transportation, railways, bridges, tracks, tunnel expansion joint stray current drainage terminals and stray current drainage strips (networks) are connected by welding the drainage strips and copper terminals or extruding welding terminals, punching holes, etc. , wires, connecting bolts, pads, wire clips, wires, easy to enter the concrete in the hole, many mechanical joints, exposed, easy to steal, oxidized, loose, the more joints, the greater the resistance, the long connecting conductor, and the copper bar cannot be used after being stolen. Repairing wastes manpower, material, money, complicated construction takes a long time, and work efficiency is low. Contents of ...
