The utility model provides a filling body displacement monitoring device used for top board settlement volume detection. The filling body displacement monitoring device comprise a pedestal used for fixation, an inner cylinder which moves along with settlement of a filling body, an outer cylinder used for supporting the inner cylinder, a sealing sleeve used for connecting the outer cylinder and the inner cylinder in a sealing manner, a fastening sleeve used for compressing tightly the sealing sleeve in the outer cylinder and a detection assembly used for filling body settlement volume measurement. The pedestal is provided with a wire outlet opening, the inner cylinder is connected with a top board, the top part thereof is connected with an inner cylinder sealing cover, and the detection assembly is arranged in the outer cylinder and is connected with the inner cylinder to measure displacement of the inner cylinder. Compared with the prior art, the filling body displacement monitoring device of the utility model is advantageous in that joints among inner cylinder ports, the inner cylinder and the outer cylinder are all reliably sealed; the detection assembly is enabled to be in a sealed space formed by the outer cylinder and the inner cylinder and can be free from interference of working environment, the filling body displacement monitoring device can also be applied to a filling application place having a certain hydraulic pressure, and thus the monitoring device is reliable in work and long in service life.
