Method for Preventing Shield Casing Catching Due to Too Large Frictional Resistance in Earth Pressure Balance Shield Machine

A method for preventing shield jamming by excessive frictional resistance in earth pressure balance shield which involves real-time monitoring of earth pressure signal for earth pressure on the shield body through sensors on the shield machine. Combined with the known parameters, resistance in the shield machine is calculated. The friction F1 between the shield body and the stratum is calculated by CPU module in PLC according to the earth pressure signals on a real-time basis. Then the friction F1 is determined whether it is less than or equal to the difference between the quotient of dividing total propulsion force Ft by correction coefficient Kxz and total resistance of F2, F3, F4 and F5; if so, it is under normal propulsion; if not, the warning device alarms. Therefore forced shut down due to shield jamming is effectively avoided, the construction risk is reduced and the construction efficiency is improved.
