摘要： PURPOSE: To obtain method and apparatus for measuring the water content of aggregate at batcher plant in which the percentage of water content of aggregate is measured accurately by a real time processing system and concrete having stabilized unit water content can be supplied. CONSTITUTION: At the outlet of an aggregate receiving bin 12, the percentage of water content of aggregate is measured when the aggregate is flowing down by means of a moisture content meter 13. A decisions is then made whether the measuring time of the percentage of water content is appropriate or not and the percentage of water content is equal to a set value or not. When the measuring time is appropriate and the percentage of water content is equal to a set value, current mixing ratio of aggregate, cement and water is sustained. When the measuring time is not appropriate, the opening of a cut gate 14 is regulated and when the percentage of water content is not equal to a set value, the quantity of water is regulated.

摘要： PROBLEM TO BE SOLVED: To reduce an amount of wear of a cutter bit by eccentrically supporting a cutter part on a rotator fixed on the front end of a driving shaft, providing a step on the adjacent cutter bits, and overlapping excavated holes. SOLUTION: First to fourth cutter bits 31-34 different in length are used for a cutter part 30. Steps are provided on the adjacent cutter bits, an excavation hole through each cutter bit 31-34 is made substantially circular shape or substantially annular shape, and the cutting locus the adjacent cutter bits are overalapped to partially. Thereby when cutting is performed, a step is produced in the direction of excavation, an already cut preceding cutting part 40 is produced between the cut locus 35 of the cutter bit 31 and the cut track 36 of the bit 32. After the bit is previously cut, the bit 32 simply passes the cut part 40. Thereby the cutting torque of the bit 32 and pushing force are unnecessitated, and miniaturization of a hydraulic unit and a driving motor can be contrived.

CONSTITUTION:A density and moisture measuring unit 31a using radio-isotope is provided to a spoke 9 in an excavator 3 so as to detect the density and moisture ratio of dug earth from the ground, from which a particle weight WS1 of the dug earth is calculated. Further, a density and moisture measuring unit 31c is provided in an earth discharging pipe 17 in an earth discharging device 8 so as to detect the density and moisture of discharged earth, from which a particle weight WS2 of the discharge earth is calculated. Then, measurement is made additionally by an additive flow meter so as to calculate a particle weight WB of additive. Thus, the rotational speed of the earth discharging device 8 and the advancing speed of a shield jack are suitably adjusted so as to satisfy WS2 = WB + WS1. Thereby it is possible to optimally manage the volume of discharged earth.
