Totally-enclosed sound barrier and mounting method thereof
The invention relates to the technical field of totally-enclosed sound barriers for high-speed railways, in particular to a totally-enclosed sound barrier and a mounting method thereof. A totally-enclosed sound barrier comprises a cement foundation, foundation bolts, a transition beam, a steel structure framework and unit sound absorption and insulation plates. The transition beam is C-shaped steel, screw holes for fixing the steel structure framework are formed in the upper plane of the transition beam, foundation bolt holes are formed in the bottom plane of the transition beam, and expansion joints are additionally arranged on the transition beam at the bent position. The steel structure framework is H-shaped steel, a fixing plate is welded to the bottom end of the steel structure framework, and screw holes in the fixing plate are aligned with screw holes in the upper plane of the transition beam. The unit sound absorption and insulation board is divided into a rectangle or a longitudinal arc according to different door frame type steel structure frameworks or arch-shaped steel structure frameworks, a supporting frame is formed by an aluminum alloy frame in the unit sound absorption and insulation board, one side of the aluminum alloy frame is provided with the sound absorption and insulation board, the other side is provided with the aluminum alloy hanging board, and the middle is provided with rock wool. The upper side, the lower side, the left side and the right side of each unit sound absorption and insulation board are provided with corresponding tenon-and-mortise structures of trapezoidal bosses and grooves.
本发明涉及高速铁路全封闭声屏障技术领域，尤其涉及一种全封闭式声屏障及其安装方法。一种全封闭式声屏障，包括水泥地基、地脚螺栓、过渡梁、钢结构骨架、单元吸隔音板。过渡梁为C型钢，其上平面有固定钢结构骨架的螺孔，底平面有地脚螺栓孔，在弯曲处的过渡梁加设伸缩缝。钢结构骨架为H型钢，底端焊接有固定板，固定板上的螺孔与过渡梁上平面的螺孔对齐。单元吸隔音板依门架式钢结构骨架或拱形钢结构骨架不同分为长方形或纵向圆弧形，单元吸隔音内部由铝合金框架构成支撑架，铝合金框架的一侧为吸隔音板、另一侧为铝合金挂板，中间为岩棉，单元吸隔音板的上下、左右四侧设有对应的梯形凸台和凹槽的榫卯结构。
