    • PURPOSE: A roadbed sound absorption block for an urban railway is provided to reduce repair time and costs by allowing a user to easily change a sleeper, a rail and the damaged sound absorption block. CONSTITUTION: A roadbed sound absorption block(1) for an urban railway comprises a lower block(2) in a gap with a roadbed(A). The lower block is attached to the upper surface of the roadbed, and one side of the lower surface of the sound absorption block is inserted into the upper end with female and male bond(13). A mounting protrusion(21) is formed so that the sound absorption block is mounted on the one end of the upper surface of the lower block. The sound absorption block comprises a protrusion on both ends, and a sound absorption unit is included in the center of the protrusion. A mounting groove(13a) is formed on the lower surface of the sound absorption block, and a connection protrusion(14a) and a connection groove(14b) are included in the center of the both ends of a longitudinal direction.
    • 目的:提供城市铁路的路基吸声块,通过允许用户轻松改变轨枕,轨道和损坏的吸音块,减少维修时间和成本。 构成:用于城市铁路的路基吸声块(1)包括与路基(A)间隙的下块(2)。 下部块附接到路基的上表面,吸音块的下表面的一侧被插入上端,并具有阴和阳键(13)。 安装突起(21)形成为使得吸声块安装在下部块的上表面的一端。 吸音块包括两端的突起,并且在突起的中心包括吸声单元。 在吸音块的下表面上形成安装槽(13a),并且在长度方向的两端的中心包括连接突起(14a)和连接槽(14b)。
