Abstract

The invention discloses a rail transit ground line trackside integrated system capable of reducing noise, which is characterized in that a plurality of foundation structures are arranged beside a rail along the extending direction of the rail, and embedded parts are arranged on the foundation structures; each embedded part is connected with a stand column, a cross beam is installed on the top of each stand column, and an evacuation platform footpath plate is laid on each cross beam. A plurality of mounting hole groups are formed in at least one side of the upright post, and cable brackets are mounted on part or all of the mounting hole groups; wherein a sound barrier screen body is vertically installed between every two adjacent stand columns, and the sound barrier screen body is transversely installed between every two connected cross beams. The integrated, standardized, modularized and prefabricated design scheme is adopted, the installation space is saved, the construction and installation efficiency is improved, the operation and maintenance cost is reduced, and the trackside system manufacturing cost is saved.
