Zusammenfassung:	An automated and synchronized control system for bundled steel strand anchoring. The system is provided with a pre-tensioning device, an integrated tensioning device, a hydraulic pump station, and a main control center. Each part is organically connected via high pressure hydraulic tubing, a data transmission cable, and a control component. The main control center issues a command and the hydraulic pump station then actuates the pre-tensioning device and integrated tensioning device to perform a tensioning operation in accordance with a pre-configured program. An integrated multi-piston, single-shaft pre-tensioning jack comprises a hydraulic cylinder and a piston. The hydraulic cylinder is provided with multiple piston openings. Each of the pistons is installed within a piston opening to form an integrated multi-piston structure. By using the pre-tensioning jack with a structure comprising a single hydraulic cylinder and multiple pistons a high degree of integration is achieved. The invention can realize simu
