隧道掘进机通风除尘和配套辅助设备的应用

TBM Ventilation and Dust Removal and Application of Auxiliary Equipment

在长大隧道施工中,通风除尘是极其重要的,不良的通风会导致粉尘含量超标,将严重危害作业人员的身心健康;同时,不利于设备的正常运转。吐库二线中天山隧道TB880E型隧道掘进机设备配置复杂,机电、液压设备多,运行中对作业环境、温度要求较高;ZED激光导向系统要求洞内粉尘含量低、可见度要高。其配套的通风、除尘、降温设备通过作业人员在操作、维修、保养方面严格遵照规范,合理使用,完好率一直保持在92%以上,为洞内施工创造了通风充足、粉尘含量低及低温的作业环境,很好地满足了中天山隧道的施工需要。

During tunnel construction, the ventilation and dust control are extremely important, and bad ventilation will lead dust level excessive, cause serious damage to the physical and mental health of workers, and at the same time is not good to the normal operations of equipment. The TBM for Zhongtianshan Tunnel on the Turpan--Korla Second Line is complicated in configuration, which has much M＆E and hydraulic equipment, and has high level request for the working environment and the temperature in the operation; ZED laser guidance system demands a low dust content and high visibility. Its supporting equipments for ventilation, dust removal and cooling, under strict compliance with the specifications in terms of operation, repair and maintenance, as well as reasonable use of workers, remains a tact percent of 92% or more, which has created a working environment with adequate ventilation, low dust content and low temperature during construction.
