Nuclear power plant master control room noise reduction and vibration reduction wall structure and vibration reduction method
The invention provides a noise reduction and vibration reduction wall structure and vibration reduction method for a main control room of a nuclear power plant, and the vibration reduction wall structure comprises a first shaft wall which is located at one side of the main control room; the first span wall is arranged on the side, away from the master control room, of the first shaft wall; a main steam pipeline led out of the nuclear island penetrates through the first shaft wall and the first span wall, and the main steam pipeline is supported on the first span wall. According to the noise reduction and vibration attenuation wall body structure and the vibration attenuation method of the nuclear power plant main control room, vibration generated by fluid operation in the main steam pipeline is transferred to the first span wall in the area outside the main control room, and the propagation path for transferring the vibration to the main control room is cut off, so that the noise of the main control room can be greatly reduced, and the acoustic environment of the main control room is greatly improved; and a relatively good acoustic working environment is provided for workers in a main control room.
本申请提供一种核电厂主控室降噪减振墙体结构和减振方法，减振墙体结构，包括：第一轴墙，其位于所述主控室的一侧；第一跨墙，其设置于第一轴墙远离主控室一侧；其中，从核岛引出的主蒸汽管道穿过第一轴墙和第一跨墙，且主蒸汽管道支撑于第一跨墙上。本申请的核电厂主控室降噪减振墙体结构和减振方法，将主蒸汽管道内由于流体运行产生的振动转移传递至主控室以外区域的第一跨墙，隔断了振动传递至主控室的传播路径，从而可以大幅降低主控室噪声，极大改善主控室声学环境，为主控室工作人员提供较好的声学工作环境。
