れる土砂量を精度よく測定する方法はなかつた。(Prior art) Fig. 5 shows a method for measuring the amount of soil removed by a conventional shield excavator, in which soil is removed from the ground 3 into the cutter chamber 4 as the cutter head 2, which is disposed on the front of the shield excavator 1, rotates. The excavated soil 5 is
It is discharged by the screw conveyor 6, conveyed backward by the following belt conveyor 7, loaded on the unloading trolley 8, and conveyed out of the mine. At this time, in order to operate the shield excavator rationally, it is necessary to constantly monitor the amount of excavated soil and control the amount of excavated soil to ensure that it is not too much or too little. There was no way to accurately measure the amount of sediment.

ない。(Problem that the invention aims to solve) Conventionally, the amount of soil removed was not measured continuously, so the temporal fluctuations in the amount of excavated soil could hardly be grasped, and the amount of soil removed in the past Since the measurement point is located at the end of the excavated soil transport equipment inside the shield excavator, there is a time delay between excavation and measurement, making it impossible to utilize the measurement results of the amount of soil removed for excavation management at the face. Furthermore, since it is not possible to know the deformation of the excavated soil during transportation, it is not possible to quantitatively grasp the amount of excavated soil at the face, which should be managed.
また前記従来の方法は、容量の大きい〓搬出用
トロツコを用いた土量管理であるため、測定精度
