Embodiment Construction

[0012] A railway has a width of 11 meters and a length of 300 meters. Both sides of the road are all schools and living areas. As the school and living area are close to the railway, the noise pollution is serious. In order to thoroughly control road noise pollution, fully enclosed noise barriers will be installed on roads.

[0013] The total height of the fully enclosed noise barrier is 7.5 meters. Reference figure 1 This project consists of 75 symmetrical left and right support frames and top support frames. The top support frame and the side support frame are connected, and the connection point of the top support frame G and the side support frame is higher than the top support frame F and the side The connection point of the top support frame (that is, the height of the top support frame G6 is higher than the top support frame F5), the top sound insulation board is installed between the top support frame F and the top support frame G, and a slope is formed between the top su...

Abstract

The invention provides an all-closed noise barrier. The noise barrier comprises multiple zygomorphous side support frames and multiple arc support frame units different in top radian height. The noise barrier is characterized in that the left side support frame of each unit is composed of a portion A and a portion B, each right side support frame is composed of a portion C and a portion D, and the left side support frames and the right side support frame form a main support frame body. Each top support frame is composed of a top support frame F and a top support frame G, the top support frames are connected with the side support frames, and connection points of the top support frame G and the side support frames is higher than connection points of the top support frames F and the side support frames.

Description

Technical field [0001] The invention belongs to the field of environmental protection, is mainly used for traffic noise management, and specifically relates to a fully enclosed sound insulation barrier. Background technique [0002] There are many environmentally sensitive points along the road, such as residential quarters, schools, office buildings, etc. The noise generated by vehicle driving causes great noise pollution to the environmentally sensitive points along the line. Summary of the invention [0003] In order to solve the above-mentioned noise pollution problem, the present invention proposes a fully enclosed noise barrier with good sound insulation and noise reduction effect. [0004] A noise barrier structure includes a plurality of symmetrical side support frames on both sides and a plurality of arc-shaped support frame units with different top arcs. The feature is that the left side support frame of each unit consists of part A and The B part is composed of two parts...
