摘要
长距离大口径土压平衡顶管施工过程中,易遇有害气体从土层中逸出,焊接钢管时的烟雾、粉尘极易造成人体缺氧等安全事故的发生。另外空气中的温度、湿度易影响掘进机电机正常工作。良好的通风措施,可保障人身安全及设备的正常运转。
During the process of pipe jacking of compression balance about long-distance and large-diameter-hole,the harmful gases can easily escape from the soil.The smoke,dust which can easily cause hypoxia and other security incidents when the steel pipe is welded.The air temperature and humidity are also influence normal work of excavation during mechine.Good ventilation measure can protect human safety and equipment running nomally.
