Acoustic barrier easy to splice and used for train track

Abstract

The invention discloses an acoustic barrier easy to splice and used for a train track. The acoustic barrier comprises a splicing base and an acoustic barrier body, wherein the outer surface of the lower end of the splicing base is fixedly provided with threaded steel bars, the inner surface of the upper end of the splicing base is provided with a sliding groove, the side, close to the sliding groove, of the outer surface of the upper end of the splicing base is fixedly provided with a limiting block, a gasket II is fixedly installed on the inner surface of the inside of the splicing base, a gasket I is fixedly installed on the side, close to the gasket II, of the inner surface of the inside of the splicing base, a clamping groove II is formed in the lower portion, close to the gasket II, of the inner surface of the inside of the splicing base, and a clamping groove I is formed in the lower portion, close to the gasket I, of the inner surface of the inside of the splicing base. The acoustic barrier easy to splice and used for the train track is provided with the splicing base and an extensible plate so that the acoustic barrier can be spliced more quickly and conveniently and have acertain extension adjusting structure, and a better use prospect can be brought.

Description

technical field [0001] The invention relates to the field of railway equipment, in particular to an easy-to-assemble noise barrier for train tracks. Background technique [0002] The existing resistive noise barrier consists of a front panel, a rear panel and a side panel to form a closed box structure, forming a modular unit. The front panel is a galvanized steel plate with a perforation rate of 25%. The back panel and side panels are galvanized steel sheets without perforation. From the perspective of appearance, colored steel sheets can also be used. The moisture-proof centrifugal glass wool board is filled between the two layers of panels. The sound-absorbing material is covered with polyvinyl fluoride film. The columns are twelve No. I-beams, with a column spacing of two meters, the columns are inserted into the reinforced concrete foundation, the standard plate is inserted between the I-beams, and fixed with fasteners, the installation, maintenance and replacement are ...

[0002] The existing resistive noise barrier consists of a front panel, a rear panel and a side panel to form a closed box structure, forming a modular unit. The front panel is a galvanized steel plate with a perforation rate of 25%. The back panel and side panels are galvanized steel sheets without perforation. From the perspective of appearance, colored steel sheets can also be used. The moisture-proof centrifugal glass wool board is filled between the two layers of panels. The sound-absorbing material is covered with polyvinyl fluoride film. The columns are twelve No. I-beams, with a column spacing of two meters, the columns are inserted into the reinforced concrete foundation, the standard plate is inserted between the I-beams, and fixed with fasteners, the installation, maintenance and replacement are very simple; the existing noise barrier is in the There are certain disadvantages when using it. The installation steps of the traditional noise barrier are relatively complicated, which increases the time required for the assembly of the noise barrier. The traditional noise barrier does not have a telescopic adjustment structure, and it cannot be properly adjusted according to the size of the sound source. Users have a certain impact, so we propose an easy-to-assemble noise barrier for train tracks
