Expressway sound insulation barrier installation construction method

Abstract

The invention relates to a highway sound insulation barrier installation construction method, relates to the technical field of municipal facilities, and uses a highway sound insulation barrier, the sound insulation barrier comprises a sound insulation plate and fixing columns arranged on the side edge of the sound insulation plate and connected end to end, and an installation device is arranged on the fixing columns. The installation device and a cement fence beside a high-speed road are fixedly installed, a rapid penetrating opening is formed in the sound insulation plate, the rapid penetrating opening penetrates through the sound insulation plate, a sound insulation cover plate covering the rapid penetrating opening is arranged on the sound insulation plate, and the sound insulation cover plate and the sound insulation plate are installed and fixed through an installation piece. The device has the effects of being convenient to mount and dismount and facilitating personnel to pass through so as to reduce the occurrence probability of secondary injury accidents.

Description

technical field [0001] The invention relates to the technical field of municipal facilities, in particular to a method for installing and constructing an expressway noise barrier. Background technique [0002] Noise barrier, also known as sound insulation wall, is one of the methods to relieve noise, and it is also the most effective way to alleviate noise from roads, railways and industrial noise sources. It is used on both sides of the road to isolate the disturbing noise caused by the high-speed driving of the vehicle; because of the good sound insulation effect and long service life of the sound insulation barrier, it is more and more favored by people. [0003] In the actual construction and installation process of the existing highway noise barriers or sound insulation walls, the sound insulation walls are usually produced in the factory, and then the sound insulation walls are transported to the side of the expressway, and the sound insulation walls are poured by ceme...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: since the sound insulation wall is installed by pouring cement, when the sound insulation wall is damaged due to a vehicle accident or bad weather, it is not easy to disassemble the sound insulation wall, so that it is not easy to repair the sound insulation wall. Replacement; in addition, when a traffic accident occurs at the position of the sound insulation wall when the vehicle is driving, due to the obstruction of the sound insulation wall, the driver and passengers are not easy to move through the sound insulation wall to a safe zone, so it is easy to cause secondary injury accidents. Therefore, there is still room for improvement
