Track stray current grounding terminal positioning device and application thereof

Abstract

The invention discloses a track stray current grounding terminal positioning device and application thereof. An application method comprises following steps: fixing stray current grounding terminals on the track stray current grounding terminal positioning device, pouring a reinforcement cage, vertically lapping the track stray current grounding terminal positioning device between two tracks before concrete is solidified, and symmetrically placing the stray current grounding terminals fixed by using the track stray current grounding terminal positioning device at an expansion joint template; finely adjusting the reinforcement cage according to the position of the stray current grounding terminals, and binding and fixing the stray current grounding terminals and the reinforcement cage through a binding wire; after the concrete is solidified, dismounting the positioning device, and carrying out welding and secondary pouring on the reinforcement cage and the stray current grounding terminals. The problems that in traditional construction, the reinforcement cage and the stray current grounding terminals are welded firstly and then poured, so that the reinforcement cage deforms, the stray current grounding terminals incline and sink, concrete is immersed, the appearance quality is poor, the design requirement cannot be met, and the using performance of the stray current grounding terminals is affected are solved.

Description

technical field [0001] The invention relates to the field of track construction, in particular to a track stray current grounding terminal positioning device and its application. Background technique [0002] At present, the construction process of stray current grounding terminals needs to be poured for the first time after the terminal welding is completed. Each welding point takes 10 minutes to work, and the welding speed is difficult to guarantee, which affects the construction of the next process; moreover, according to the design requirements, miscellaneous Dissipative current grounding terminals should be welded with steel bars and poured into the concrete. During the construction process, the steel cage is squeezed by the concrete when the concrete is poured, often causing the terminals to skew, sink, sink into the concrete, and have poor appearance quality, which cannot meet the design requirements and affect its use. performance issues. [0003] Therefore, how to ...
