Adjustable automatic load-reduction sound barrier
The invention discloses an adjustable automatic load-reduction sound barrier. The load-reduction sound barrier comprises an upper-layer plate, a middle-layer plate, a lower-layer plate, a base and stand columns. The adjustable automatic load-reduction sound barrier has the advantages that on the basis of theoretical analysis and numerical simulation calculation, noise mainly transmitted by a pantograph and a wheel rail can be straightly blocked and absorbed through a seamless structure of the upper-layer plate and the lower-layer plate; the spreading direction and spreading distance of sound waves can be effectively changed while the middle-layer plate can guarantee that train wind and natural wind pass freely, and the aim of lowering noise is achieved; mounting is convenient, and economical efficiency is achieved; the sound barrier is of an assembled structure, flow-process construction can be achieved, work efficiency can be improved, construction time can be shortened, and a large amount of manpower and cost can be saved; the cost is saved; the structure is durable; the negative influence of wind loads on the sound barrier is eliminated through the sound barrier, fatigue damage of loads of the train wind and the natural wind to the structure of the sound barrier is reduced, and therefore the aims of prolonging the maintenance period and service life of the structure of the barrier are achieved, and the use cost is greatly saved.
