Design method of ventilation system in construction stage of final joint of submarine immersed tunnel
The invention discloses a design method of a ventilation system in a construction stage of a final joint of a submarine immersed tunnel. The design method comprises the following steps: P1, determining ventilation quantity; p2, selecting ventilation equipment; p3, arranging ventilation equipment; p4, selecting an air pipeline; p5, air pipe material selection; an air supply mode of combining a dehumidifier and an air feeder is adopted for air supply, air supply parameters can be changed, the hygienic standard in a final joint and the comfort level of workers are further improved, a ventilation system is constructed according to a tunnel, existing carriageways and flues are used as air supply and exhaust routes, an air duct is not independently arranged or the tunnel space is not occupied, and the ventilation efficiency is improved. Other construction operations are not affected during construction, and the device can be dismantled after construction and does not affect later tunnel operation.
一种海底沉管隧道最终接头施工阶段通风系统设计方法，其步骤为：P1.确定通风量；P2.通风设备选择；P3.通风设备布置；P4.风管路由选择；P5.风管材质选择；本发明送风采用除湿机加送风机组合的送风方式，可以改变送风参数，进一步提高最终接头内的卫生标准及工作人员舒适度，通风系统根据隧道构造，利用已有行车道、烟道做为送风排风路由，不单独设置风道或占用隧道空间，施工期间不影响其他施工作业，施工后可拆除，不影响后期隧道运行。
