Sound absorption and load reduction sound barrier unit and sound barrier thereof
The invention relates to the technical field of sound barriers, in particular to a sound absorption and load reduction sound barrier unit and a sound barrier thereof. The sound absorption and load reduction sound barrier unit comprises a shell, a sound absorption material filled cavity and connecting ends, wherein the sound absorption material filled cavity is in the shell; the sound absorption and load reduction sound barrier unit is characterized in that the shell comprises an upper cover plate, a lower cover plate, a rear back plate and a front panel; a sunken part which is sunken towards the interior of the sound absorption material filled cavity is formed in the lower cover plate; a protrusion part which protrudes towards the exterior of the sound absorption material filled cavity is formed on the upper cover plate; through holes are respectively formed in the front panel and the lower cover plate; the connecting ends are respectively in insert connection with the ends of the shell; after insert connection, an unfilled space is formed. The sound absorption and load reduction sound barrier unit has the beneficial effects that the structure is simple, production and transportation are convenient, inspection and maintenance are convenient, and the manufacturing cost is low; the running noise of a high speed railway train can be effectively absorbed, and moreover, the pulsating pressure acting on the sound barrier by air motion in the high-speed running process of the train can be effectively reduced; the service lives of the sound barrier and railway bridges are prolonged.
