This utility model proposes a weighing and monitoring system for pile foundation construction fill material, belonging to the technical field of driven stone pile drivers. This utility model achieves accurate acquisition of the amount of crushed stone filled during construction by weighing and accumulating the weight of the fill material in the concrete hopper each time. The technical solution includes a pile driver mast, a pile pipe, and a concrete hopper. A power hammer is fixed to the top of the pile pipe, and a first sliding wheel is provided on one side of the power hammer. A track is provided on the side of the pile driver mast opposite to the pile pipe, and the track cooperates with the first sliding wheel. A crossbeam is provided at the top of the pile driver mast, and a first pulley block is provided on the crossbeam. The power end of the first pulley block is connected to a first winch, and its resistance end is connected to a weighing device. The weighing device has a hook, which is connected to a fixed frame. The concrete hopper is fixed on the fixed frame, and the weighing device is used to weigh the weight of the fill material in the concrete hopper.
