According to the telescopic sound barrier unit plate, a sound absorption assembly is fixedly arranged in a cavity of a plate body in the longitudinal direction; the two ends of the plate body are open and provided with telescopic assemblies respectively. The telescopic assembly comprises a sectional material embedded in the end opening of the plate body and a telescopic piece arranged in the sectional material in a sliding mode. Sliding sleeves are respectively suspended at the top and the bottom in the sectional material; one end of the guide rod is fixedly connected with the telescopic piece, and the other end of the guide rod is a movable end; one end of the tension spring is fixedly connected with the sliding sleeve, and the other end of the tension spring is fixedly connected with the end head of the movable end. By means of the telescopic assembly, on the premise that the original function of the sound barrier unit plate is not changed, the original length can be kept before installation, installation is convenient, the length can be freely increased by 0-15 cm on the basis of the original length after installation, and the telescopic assembly is used for resisting deformation of a totally-closed sound barrier steel structure and the change of the distance between stand columns due to the fact that an expansion joint is affected by temperature. Therefore, the sound barrier unit plates are prevented from falling off between the stand columns, and safety of railway operation is guaranteed.
本发明的一种可伸缩声屏障单元板，吸声组件沿纵向固设于板体的空腔内；板体的两端敞口并分别配设有伸缩组件；伸缩组件包括嵌置于板体端口的型材，和滑动的置于所述型材内的伸缩件；型材内的顶部和底部分别悬设有滑套；沿滑套滑动的导杆，其一端固接伸缩件，另一端为活动端；且活动端套设有拉簧，拉簧的一端固接滑套，另一端固接所述活动端的端头。其通过伸缩组件，在不改变声屏障单元板原始功能的前提下，在安装前既能保持原始长度，便于安装，在安装后还可在原始长度的基础上自由增加0~15cm的长度，用来抵抗全封闭声屏障钢结构变形及伸缩缝受温度影响导致立柱之间距离的变化，从而防止声屏障单元板在立柱之间脱落造成铁路运营的安全。
