摘要： PURPOSE:To measure the flow direction of a fluid which has an extremely low velocity by charging and discharging a substitute fluid, having different electrical or chemical properties from the fluid to be measured, in and from an observation part, forming a lump of the substitute fluid of prescribed size, and then detecting the movement of the lump of the substitute fluid electrically. CONSTITUTION:A prescribed amount of an electrolyte 80 is discharged from a discharge opening 36A into an observation part 20 as shown by (A). When the electrolyte 80 moves as underground water W moves, this movement is detected in the form impedance variation between electrodes by measuring electrodes 11A, 11B...15A, and 15B. Then, the measurement of the flow of the underground water W is started at an electrode having said impedance variation.

摘要： PURPOSE:To measure the flow direction of a fluid with an extremenly low velocity by arranging a substitute material having different electric properties from the fluid to be measured at an observation part, and then detecting the movement of the substitute material simultaneously in a four-electrode method using a group of measuring electrode and on time-division basis from the group of measuring electrodes. CONSTITUTION:An observation part is charbed with a substitute material, such as an electrolyte and pure water, having different electric properties from undergroun water W. When the underground water W flows into the observation part, the substitute material moves, so its movement is detected in the form of variation in conductivity by using four adjacent electrodes among external electrodes 71-82 and internal electrodes 88-94, thus measuring the flow direction. For this conductivity measurement, the electrode groups P1, P2... are connected to a measuring circuit on time-division basis.

摘要： PURPOSE:To gather easily and exactly samples of gravel strata, by gathering samples through a movable edge which is freely switched at the lower end of a sample tube. CONSTITUTION:A transverse rod 8 is brought down to a prescribed position and a tube 1 is driven into the ground in the opening state of a freely movable edge part 2 equipped with driving edges 4 and also provided with a section at a lower end opening part of a quadrangular sample tube 1, then the edge part 2 is entered into qravel strata. When a boring rod is rotated in this state, only a screw gear 9 is rotated without turning the tube 1 and is moved to the upper part. Accordingly, the transverse rod 8 and a movable rod 5 are pushed up with the elastic force of a spring 6 and the edge part 2 is turned toward the inner direction and the opening part of the tube 1 is closed, and the gravel stratum which is held in the edge 2 is gathered out easily and exactly into the tube 1, and it becomes a sample for grain size characteristics, etc. of the gravel strata.

摘要： PURPOSE:To measure the minute velocity of flow simply and with high accuracy by a method wherein in the measurement of flow velocity and direction of the underground water, plurality of electrodes filled in advance with electrolyte are inserted into the underground water to detect the resistance change basing on the replacement dilution of electrolyte on account of water stream. CONSTITUTION:Inside the cylindrical sleeve 6 the electrodes 1-5 are provided in the fixed intervals and the inside of the room 9 is filled with water. This pick-up part is inserted into the water and after the turbulence because of insertion is calmed down the sleeve 6 is gradually pulled up, then the water stream 10 dilutes and replaces the electrolyte 11 slowly. At this time the minute current is made to flow in the electrode to measure the resistance change, the resistance value rises because of dilution and replacement of the electrolyte and the traveling speed of electrolyte, namely the flow velocity of the underground water can be measured. When the electrodes are arranged radially in the cylindrical sleeve, the flow direction is also judged depending on whether the starting point of the registance is early or delayed.

摘要： PURPOSE:To improve accuracy and efficiency by using two kinds of water permeability coefficients by the change in the rate of underground permeating water infiltration and the change in recovery water level. CONSTITUTION:A pipe 13 mounted with a porous point 11 and a cone 12 at the end is driven through a boring hole 9, and a compressor 1, a blast air barometer 3, a flowmeter 4, a water level gauge 5 and a permeated air barometer 6 connected to its head 7. A water permeability coefficient is obtained from the change in the rate of underground permeating water infiltration per unit time by air pressure or the water permeability coefficient A is obtained from the change in underground infiltration rate per unit time by air pressure, thereafter the water level is lowered down to the porous point by the increased air pressure; thereafter, the air pressure is released and the water permeability coefficient B is obtained from the change in the recovered water level per unit time under atmospheric pressure. The water permeability coefficient B is corrected based on the water permeability coefficient A. Thereby, the final water permeability coefficient of high accuracy is obtained.

摘要： PROBLEM TO BE SOLVED: To precisely, easily and quickly detect a leakage position in various reservoir facilities such as an artificial pond or water reservoir for golf course, a storage reservoir or the like by detecting a minute leakage sound wave. SOLUTION: A minute leakage sound characteristic accompanying a leakage is caught by a field measurement and compared with a reference characteristic free from leakage to extract a position where the frequency natural to leakage is prominent, whereby the leakage position is specified. According to this, the detection of a leakage position can be facilitated, and the preciseness and quickness in the specification of a leakage position can be particularly improved.
