Problems solved by technology

[0004] The existing rail transit sound barriers do not have a real-time noise monitoring system. Once the sound barrier is damaged during the operation of the rail transit or there are sound insulation loopholes in the sound barrier at the beginning of the installation, it will not be able to achieve a good sound insulation effect during use, which will affect the surrounding environment. Causes noise pollution without real-time monitoring

Abstract

The invention discloses a wedge type sound barrier which comprises a plurality of steel columns arranged on one side of a track, and adjacent steel columns are connected and fixed through supporting beams. Sound absorption wedges are arranged among the steel columns. A noise sensor is arranged on one side of each sound absorption wedge away from the track. The noise sensors are connected with a control circuit, and the control circuit is connected with a storage battery. The wedge type sound barrier is durable in structure and stable in performance and can monitor noise on the outside of a track traffic sound barrier in real time, and noise reduction and sound reduction quantity of the track traffic external hanging sound barrier is 10-15 dB (A).

Description

technical field [0001] The invention relates to a sound barrier, in particular to a wedge type sound barrier. Background technique [0002] With the progress of society and the development of cities, people's living standards continue to improve, urban traffic and intercity traffic has become the most closely related issues to us. Therefore, reducing the disturbance of noise to residents on both sides of the road has become an important task in the current urban construction of our country. Great convenience, but residents who live near these highways, light rails and high-speed rails suffer from traffic noise. In order to improve the living environment of citizens, relevant departments have installed various sound-absorbing and insulating barriers on both sides of the road and along the light rail and high-speed rail. [0003] The sound-absorbing wedge is a special sound-absorbing structure used for noise reduction. It can usually be divided into two parts: the tip and th...
