厦门抽水蓄能电站地下工程施工通风设计

Ventilation Design for Underground Engineering Construction of Xiamen Pumped Storage Station

笔者以厦门抽水蓄能电站地下工程为对象,根据建筑物布置、施工通道条件,按施工程序、《煤矿安全规程》要求,将地下工程施工通风分三期布置、设计。以施工经验和公式计算为基础,围绕一期、二期、三期施工通风中风量、阻力、功率、风机选型及运行效率,分析、解决地下洞室群施工通风设计难点,建立一个以地下厂房为中心的洞室群施工通风的计算模块。

Taking the underground engineering of Xiamen Pumped Storage Station as the object of study,according to the layout of buildings and the conditions of construction passages,and according to the requirements of construction procedures and“Coal Mine Safety Regulations”,the authors divide the construction ventilation of underground engineering into three stages of layout and design.Based on construction experience and formula calculation,a calculation module of construction ventilation for underground cavern group is established around the air volume,resistance,power,fan type selection and operation efficiency in the first,second and third phases of construction ventilation,and the difficulties in design of construction ventilation for underground cavern group are analyzed and solved.
