Abstract: The present invention relates to a sound absorption wall for a high-speed railway tunnel which is installed in a tunnel for a high-speed train to reduce noise caused when high-speed trains pass the tunnel. The high-speed railway tunnel comprises: a sound absorption block, a prop, and pillars. The sound absorption block is formed of overlapped three rectangular plates, but the intermediate plate protrudes from the top and one side of the front and rear plates to form coupling protrusions and coupling grooves of which entire surfaces protrude or are recessed; wherein the front plate has a recessed sound absorption pattern formed thereon. As seeing from the lateral side, the prop is longitudinally and lengthily extended with the cross-section corresponding to one lower coupling groove of the sound absorption block and has multiple through-holes through which bolts are coupled to the floor from the upper part of the cross-section. As seeing from the top, the pillars are longitudinally and lengthily extended with the cross section corresponding to the other coupling groove of the sound absorption block close to the coupling protrusion of the sound absorption block. As seeing from the lateral side, support plates are fixed on the bottom of the pillars to fix the pillars on the ground by bolts. After the prop is installed between the inner wall of the railway tunnel and the trains and the sound absorption blocks are horizontally and transversely connected on the top of the prop to construct a wall frame, the pillars are installed to fix and connect the wall frame.

Abstract translation: 本发明涉及一种用于高速铁路隧道的吸声墙，其安装在用于高速列车的隧道中以减少高速列车通过隧道时引起的噪音。 高速铁路隧道包括：吸音块，支柱和支柱。 吸声块由重叠的三个矩形板形成，但是中间板从前后板的顶部和一侧突出，以形成整个表面突出或凹陷的联接突起和联接槽; 其中所述前板具有形成在其上的凹陷吸声图案。 从侧面观察，支柱纵向和长度方向延伸，其横截面对应于吸音块的一个下连接凹槽，并且具有多个通孔，螺栓通过该多个通孔从地板的上部 横截面。 从顶部看，柱子纵向和长度方向延伸，其横截面对应于吸音块的另一个连接槽，靠近吸音块的联接突起。 从侧面观察，支撑板固定在支柱的底部，通过螺栓将支柱固定在地面上。 在铁路隧道内壁和列车之间安装支柱后，将吸音块横向和横向连接在支架顶部，构成一个墙框架，柱子被安装固定并连接在墙框上。
