Road noise reduction protection structure and construction method thereof

Abstract

The invention relates to a road noise reduction protection structure and a construction method thereof. The device comprises a plurality of bases which are spliced with one another, each base is provided with a voice insulation plate. The adjacent voice insulation plates abut against each other. An arc-shaped voice baffle is arranged at the upper part of each voice insulation plate; a notch of thecircular-arc-shaped voice baffle is arranged towards the position where the road surface of the road is located; insertion grooves are formed in the face, facing the voice baffle, of each base and located in the four corners of the base. The voice insulation plates are provided with insertion rods used for being inserted into the insertion grooves. When the voice insulation plate needs to be installed, the voice insulation plate drives the insertion rod to be inserted into the insertion groove, so that the voice insulation plate is fixed to the base through the gravity of the voice insulationplate, the insertion rod is inserted into the insertion groove, the voice insulation plate can be fixed, the fixing mode is convenient and simple, and the installation efficiency of operators for thevoice insulation plate is improved.

Description

technical field [0001] The invention relates to the technical field of road construction facilities, in particular to a road noise reduction protection structure and a construction method thereof. Background technique [0002] The sound insulation screen, also known as the sound barrier, is a noise reduction tool, and its application principle is to reduce the generation of noise through the transmission channel. During the sound transmission process, encountering an obstruction will affect the transmission of sound waves; and the sound insulation screen, in addition to blocking, has an attractive material inside, which can absorb a lot of sound waves. [0003] The Chinese patent application publication number CN109797672A discloses a road wind resistance and noise reduction protective structure, including: a base and a protective screen, the protective screen is set on the base, and the base is provided with a C-shaped steel opening pointing upwards, The protective screen ...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: the first bolt is used to fix the guard plate and the C-shaped steel, so that the guard plate can drive the protective screen to be fixed to the base. When the length of the road is long, the operator needs to screw it Moving multiple first bolts for fixing, the fixing method is cumbersome, which reduces the installation efficiency of the operator when installing the sound insulation board
