摘要： PROBLEM TO BE SOLVED: To improve precision in a slope disaster predicting method, for actualization, which uses an acoustic emission technology. SOLUTION: Along with an acoustic emission technology wherein parameters are the number and magnitude of AE(acoustic emission) which takes place following a breakdown of a slope 1, the same sound as generated periodically at an artificial sound source 5 set at an AE sensor 3 and its opposite side across a collapse part of the slope 1 is measured with the AE sensor 3 and such parameter of an observed value as the level of its decay is also/additionally used. Thus, a prediction precision is improved by utilizing such nature as a sound decays as a breakdown proceeds.

摘要： PURPOSE:To enhance the structural reliability by installing a tip element at the tip of a vertically moving rotary rod through an eccentric arm mechanism in such a way as folding in the middle, furnishing a pair of agitating blades so that they rotate in the opposite directions, and spraying an improving agent intermittently. CONSTITUTION:An actuator 8 is operated to advance an output shaft 8a, and a torque is given to an arm 7 in eccentricity from the position of a pin 6 through a connecting rod 9. A tip element 2 is folded in the middle in the range 0-90 deg. with the pin 6 as the center, and in this condition, rotational excavation takes place. Rotary members 19, 20 are rotated in the opposite directions by a mechanism consisting of a piston in the tip element 2 and a pair of counter-screws so that excavation is done with agitation blades 21, wherein the rotational reaction forces are offset. An improving agent such as cement milk is sprayed pulsedly from a nozzle 24. This facilitates installation of a middle fild driving mechanism and provides a reasonable transmitting mechanism therefore, so that it can be easily fabricated and maintained, the sustaining lifetime be prolonged, and the effectibeness in execution of works and the economy be enhanced.

摘要： PROBLEM TO BE SOLVED: To control a ground-water level in a wide area. SOLUTION: Water-level indicators which are equipped with a communication function are installed respectively in ground-water observation wells 1 which are arranged in observation points in a region, to be controlled, in which a ground water current is clarified in advance. A person who intends to pump up ground water notifes a public office as a main control organization. In water pumping wells 2 it is required to install flowmeters which are equipped with a communication function and flow-rate controllers. The respective devices perform measuring operations at sampling intervals which are instructed from the computer of a control center 3, and they hold measured data, and they transmit the data to the control center 3 according to a request. The measured data are recorded and judged in a centralized manner in real time through the public line of NTT or the like. When a reference water level is lowered for a definite time or more, or when it is anticipated that the reference water level is lowered, proper water-pumping control measures can be taken automatically.
