Roadbed insertion plate type sound barrier and installation process

Abstract

The invention discloses a roadbed insertion plate type sound barrier. The roadbed insertion plate type sound barrier comprises a steel column, a barrier plate and a top buckling plate, wherein the topbuckling plate is installed above the sound barrier plate, the sound barrier plate is installed on the side surface of the steel column, a steel plate is arranged below the steel column, the upper surface of the steel plate is fixedly welded with a T-shaped steel guide rail, the surface of the lower end of the steel column is provided with a T-shaped sliding groove opening, the steel column is clamped with the T-shaped steel column through the T-shaped sliding groove opening, a shielding plate is fixedly and vertically welded to the lower surface of the steel plate, and a steel box beam is arranged on one side of the shielding plate. According to the roadbed insertion plate type sound barrier, the steel column is in sliding connection with the T-shaped steel guide rail on the steel platethrough the T-shaped sliding groove opening, the early-stage position of the steel column can be conveniently adjusted, the construction efficiency is improved, the steel plate is connected with the steel box girder embedded in a foundation pit through the shielding plate, the situation that the sound barrier plate sinks can be avoided, and the service life is prolonged.

Description

technical field [0001] The present invention relates to the technical field of sound barriers, and more specifically relates to a roadbed plug-in type sound barrier and its installation process. Background technique [0002] Traffic noise is an unavoidable urban problem in the process of urban traffic development towards high-level, high-speed, elevated and three-dimensional modernization. In order to eliminate or slow down the noise pollution caused by the operation of railways and highways to the sensitive points of the acoustic environment along the line, and to ensure the physical and mental health of the residents along the line and their normal work and life, effective noise reduction measures must be taken, among which the sound barrier plays a major role in reducing noise pollution along the traffic line to a vital role. The existing sound-absorbing and sound-insulating unit panels of the sound barrier are basically single-layer panels, which have poor sound insulat...

AI Technical Summary

Problems solved by technology

The existing sound-absorbing and sound-insulating unit panels of the sound barrier are basically single-layer panels, which have poor sound insulation effects, and the sound barrier panels are fixed by riveting, which requires laborious installation and brings great inconvenience to the construction of the project.
