Environment-friendly highway sound insulation board

Abstract

The invention relates to the technical field of highway sound insulation boards and particularly relates to an environment-friendly highway sound insulation board. The sound insulation board comprises a drainage groove, a sound insulation board body, a water storage cavity, a drainage pipe, a connecting opening, a floating plate, a sewage discharge main pipe and a sewage discharge branch pipe, wherein a bottom end of the sound insulation board body penetrates through a connecting opening to be connected with an upper surface of the floating plate; one end, extending into the water storage cavity, of the drainage pipe is arranged over against a lower surface of the floating plate; in practical application, when rainwater dramatically increases, accumulated water in the drainage groove flows into the water storage cavity from the bottom of the water storage cavity through the drainage pipe, the floating plate is slowly floated along with rising of the liquid level in the water storage cavity, and the accumulated water on the highway can be effectively prevented from flowing to resident living quarters on the two sides of the highway through the sound insulation plate body; when the accumulated water in the water storage cavity is too much, the accumulated water flows to the pollution discharge main pipe through the pollution discharge branch pipe; a problem of noise generated when an automobile passes through the rural highway is solved, a problem of drainage of the pavement of the rural highway is also solved, and the living environment of residents on the two sides of the rural highway is maintained.

Description

technical field [0001] The invention relates to the technical field of sound insulation boards for expressways, in particular to an environment-friendly sound insulation board for expressways. Background technique [0002] In hilly or plain areas, most expressways need to pass through the countryside, which solves the traffic problems of rural residents and also brings noise problems to rural residents. When a car passes through a rural expressway, in order to solve the problem of car noise disturbing people, the expressway sound insulation board is often erected along the highway, but the expressway sound insulation board not only blocks the noise, but also surrounds the accumulated water on the expressway. In addition, there is no drainage structure on the edge of the existing rural expressway, and the expressway sound insulation board on the rural expressway only has the function of sound insulation. When there is too much rain or floods come , The accumulated water on t...
