Embodiment Construction

[0012] A certain railway has a width of 11 meters and a length of 300 meters. Both sides of the road are schools and living areas. Since the school and the living area are very 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 the roads.

[0013] The total height of the fully enclosed noise barrier is 7.5 meters. refer to figure 1 , this project is composed of 75 left and right symmetrical support frames and top support frames. The top support frames are connected to the side support frames. The connection point of the upper 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 an inclined plane is formed between the top support frames to form a closed The roof surface of the noise barrier. The side sound insu...

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 and is mainly used for traffic noise control, in particular to a fully enclosed sound insulation barrier. Background technique [0002] There are many environmentally sensitive points such as residential quarters, schools, and office buildings along the road, and the noise generated by vehicles will cause great noise pollution to the environmentally sensitive points along the road. Contents of the invention [0003] In order to solve the above noise pollution problem, the present invention proposes a fully enclosed sound insulation barrier with good sound insulation and noise reduction effects. [0004] A sound insulation barrier structure, comprising a plurality of side support frames symmetrical on both sides and a plurality of curved support frame units with different top arc heights, characterized in that the left side support frame of each unit is composed of part A and Part B is co...
