As described above, the first aspect of the present invention is that the trailing carriage 17 or the like is movably provided in the pit such as the excavation pit 2 so as to follow the shield machine such as the shield machine 5 or the like. It has a trailing trolley and a measuring space 50
Provided earth removing measurement space etc., the underground in the form of shear cart shear such transport train 13 having a shear loading boxes such as earth removal loading box 15a, which can pass through the soil discharge measurement space of the succeeding carriage Is provided so that traveling and positioning can be stopped freely, and a vibration work position such as a vibration work position KS and a soil discharge level measurement position such as a soil discharge level measurement position HR are set on the succeeding trolley, and at the vibration work position,
A vibrating device such as a vibrating device unit 21 capable of vibrating the soil loaded inside the sled loading box of the sludge carrier positioned corresponding to the vibration working position is provided at the soil discharge level measurement position. , The height level H1 of the soil discharged loaded inside the shear loading box of the waste transport vehicle positioned corresponding to the soil discharge level measurement position
And the like, which are capable of measuring height levels such as a laser range finder 26, a laser range finder controller 31,
Excavation for calculating the amount of excavated soil such as the amount of excavated soil Qa, Qb, Qc, Q1 loaded inside the slip loading box based on the height level of the soil discharged measured by the soil discharge level measuring means. The earth discharge amount calculation unit such as the amount calculation unit 32 is provided, and the output amount of the calculated earth discharge amount is output to the outside. To measure the amount of excavated soil using a measuring device, after loading the excavated soil in the slip loading box of the sludge carrier, make sure that the sled transport box corresponds to the vibration work position. Positioning, the excavated soil loaded inside the slip loading box is vibrated by vibrating means to flatten the upper layer portion of the excavated soil loaded inside the slip loading box, and the excavated soil inside the excavated soil. It is made uniform by eliminating voids, and then the scrap carrier is used to measure the soil discharge level in the slip loading box. Positioned so that it corresponds to the placement, the height of the soil discharged in the slip loading box, that is, the height of the soil where the upper layer is flat, is measured by the soil discharge level measuring means, and the measured soil is discharged. Based on the height level of, the horizontal cross-sectional area inside the slip loading box, etc., calculates the amount of soil discharged such as the volume of soil discharged loaded inside the slip loading box, and the calculated amount of soil discharged. Is output to the outside. That is, since the amount of soil discharged loaded inside the slip loading box is measured by flattening the upper layer of the soil and making the soil uniform so that voids inside the soil are eliminated, The calculation should be performed with the highest possible accuracy by calculation based on the height level of the soil discharged loaded inside the slip loading box, that is, the calculation of the height level and the horizontal sectional area inside the slip loading box. You can In addition, since the amount of discharged soil (that is, the volume of the discharged soil) is measured in the soil discharge amount measuring device according to the present invention without calculating the weight of the discharged soil loaded inside the slip loading box, Even in the process of calculating the quantity, the density of the soil is not used. That is, even if the soil quality of the soil to be measured changes, and therefore the density of the soil changes, it does not affect the accuracy of the measurement of the amount of soil discharged. In other words, the amount of soil discharged can be measured with the highest possible accuracy, regardless of the soil quality of the soil discharged. Furthermore, since the vibrating means vibrates the soil discharged loaded inside the slip loading box, the amount of soil discharged by the vibrating means at one time is The amount of soil that can be loaded will not be exceeded. In other words, it is convenient because it is possible to prevent a large amount of excavated soil from being carelessly vibrated by the vibrating means and the effect of the vibrating being insufficient. The trailing carriage can be moved forward with the forward movement of the shield machine, and by moving forward, the vibration working position and the earth removal level measurement position set for the succeeding carriage are set to the forward movement of the shield machine. You can move forward with it. In other words, by moving the trailing carriage forward with the advance of the shield machine, the position for loading the soil on the sled loading box, the position for exciting the soil loading on the sled loading box, and the height level of the soil loading on the sled loading box are set. Since the mutual positional relationship with the measurement position can be kept constant, the work efficiency relating to the measurement of the amount of discharged soil becomes constant regardless of the forward movement of the shield machine, which is convenient.

A second aspect of the present invention is the soil discharge measuring device according to the first aspect, wherein the trailing carriage is a gate-shaped trailing carriage surrounding the soil discharge measuring space, and the vibrating means is used. Is a vibrator such as a vibrator 25 and a drive jack 2 that can drive the vibrator up and down from an upper portion of the upper beam portion 19 and the like of the succeeding carriage toward the earth discharge measurement space.
Since the upper and lower parts of the soil discharged in the slidable loading box are made flat and the discharged soil is made uniform, the elevator is driven from the upper side of the succeeding carriage. The vibrator is moved down into the slip loading box by the means to be inserted and installed in the soil dumping, and the vibration of the installed vibrator excites the soil dumped inside the slip loading box. Further, the height of the upper layer portion of the discharged soil changes in height depending on the amount of discharged soil loaded inside the slip loading box. However, since the installation of the vibrator for the soil discharged inside the slip loading box is performed by the descent drive of the vibrator by the elevating drive means, the amount of the soil discharged inside the slip loading box is increased or decreased. The height change of the upper layer of the soil can be dealt with by adjusting the drive amount of the descent drive by the elevation drive means. That is, in addition to the effect of the first invention, the upper layer portion of the soil discharged in the slip loading box is flattened regardless of the amount of the soil discharged in the slip loading box. Since the work of homogenizing the soil is surely performed, the amount of soil discharged can be measured with high accuracy regardless of the amount of soil discharged.

A third aspect of the present invention is the soil discharge measuring device according to the first aspect of the present invention, wherein the sled carrier has a plurality of sled loading boxes arranged at a predetermined slant loading box arrangement pitch such as a pitch P1. It is a scrap carrier having a form arranged in series in the axial direction of the mine, and the soil discharge level measurement position is set closer to the mine mouth side such as the arrow B side than the vibration working position, and the soil discharge level is set. An interval such as the interval L2 between the measurement position and the vibration working position is equal to the arrangement pitch of the misaligned loading box. Therefore, by positioning one misalignment loading box at the vibration operation position, Another one of the pile loading boxes, which is adjacent to the pit side of the pile loading box, is positioned at the soil discharge level measurement position. Alternatively, by positioning one scrap loading box at the soil discharge level measurement position, another scrap loading box adjacent to the side opposite to the wellhead side of the scrap loading box (that is, the face side) is in the vibration working position. Will be positioned. That is, in addition to the effect of the first invention, when the excavated soil loaded in one scrap loading box is being vibrated, the excavated soil loaded in another scrap loading box is On the other hand, since the height level is measured, it is convenient that the entire amount of soil discharge measurement work can be performed efficiently. In addition, since the soil discharge level measurement position is set to the wellhead side of the vibration work position, the scrap loading box that has finished excavating the soil at the vibration work position moves the scrap carrier to the wellhead side. The soil is moved to be sequentially positioned at the soil discharge level measurement position on the pit side, and the soil discharge height level is measured at the soil discharge level measurement position. By the way, it is necessary to travel to the pit side in order to carry out the loaded soil to the outside of the mine after the soil is loaded in the waste loading box of the waste transport vehicle. Therefore, in order to carry out the earth removal amount measurement work,
Since the direction in which the scrap carrier is moved in order to carry the discharged soil out of the mine is the same, it is convenient to prevent the efficiency of the discharged soil carrying-out work from being deteriorated as much as possible by measuring the amount of discharged soil.
