The water transmission system is one of the important components of the locks,and the Xijin Second-Line Lock is an important navigable hub in the Xijiang River Shipping Main Line.To ensure the safe and efficient operation of the Xijin Second Line Lock,before the trial opening,water level meters are arranged in the lock chamber,valve well,maintenance door well,the front and rear of the upper(lower)lock head miter gate and the upstream approach channel.Oil pressure sensors are layed in the rod cavity and rodless cavity of each miter gate.The hydraulic characteristics of the water transmission system,the opening and closing characteristics of the valve and herringbone gate are comprehensively monitored,commissioned and analyzed.A reasonable operation mode is proposed.The results show that under the recommended operation mode,the inertia super-elevation(drop)is basically controlled within 0.10 m,which significantly improves the force conditions of the piston rod of the manned gate and can guarantee the safe operation and efficient navigation of the locks.
