摘要： PURPOSE:To enable the confirmation of the accuracy in an excavating trench hole even by using the sludge of high consistency and high viscosity by observing the wall face of an excavating trench hole by the transmission and reception of microwaves. CONSTITUTION:An antenna part 20 projects the microwave M fed via an electric code 16 from a processing unit 22 for each side wall 12a, 12b from each transmission antenna and receives the microwave M reflected therefrom by each reception antenna. The unit 22 operates the distance between each antenna part 20 and both side wall 12a, 12b based on the time delay of the microwave M between transmission and reception antenna and based on the result thereof displays as the function of the vertical distance by the depth gage which a coiler 14 serves as well. The confirmation device when performs the measurement and display of the trench width by the projection and reflection of the microwave M and the depth from the upper end of the trench hole 12 upto the lower end with gradually loosening the cord 16 of the coiler 14. The confirmation of the trench hole 12 by the microwave M can be observed clearly with good directivity and less attenuation even in case of the sludge 10 of high concentration and high viscosity being filled up inside the trench hole 12.

摘要： PURPOSE:To improve economical property, by detecting the mandrel-side relative displacement generated on lifting up drain material at the same time, with mechanical means set on the mandrel side and continuously, when the mandrel is taken out to leave the drain material in ground. CONSTITUTION:When a mandrel 10 is lifted up leaving drain material 2, the roller 18b of a rotary body 18 is rotated along the drain material 12 because the drain material 12 is energized on the projection side of the rotary body 18 by the pressure of a plate spring 16. After that, the rotation of the roller 18b is converted to electric signal by a magnetic sensor 24, and the input to a comparison operation apparatus 26 is provided. In this case, if the drain material 12 is not lifted up at the same time, the lifting speed of the mandrel 10 which is measured by an encoder 30 is equal to the lifting speed of the mandrel 10 which is found out by the magnetic sensor 24. In the meantime, if the drain material 12 is lifted up at the same time, the lifting speed of the mandrel 10 which is determined by the sensor 24 is different from the speed measured by the encoder 30. The existence and degree of the lifting-up are indicated and recorded in an indicator 32 and in a storage unit 34.

摘要： PURPOSE:To measure the amount of soil with good accuracy by calculating the sectional area through image processing of a picked-up outline, multiplying said sectional area by a speed thereby to obtain the volume per unit time, and sequentially aggregating the volumes. CONSTITUTION:A video sensor 6 obtains monochromatic binary signals through an image processing function on the basis of an outline of soil and sands picked up by a video camera 2. The video sensor 6 determines an area occupied by a window W determined by a CRT display 7 as the position of the section where the soil and sands are optically cut. The video sensor 6 outputs the shadowed area in a fan shape as the monochromatic area with the area of the shielding plate 3 and a conveyor 1 removed. The processed signal from the video sensor 6 is, together with vertical and horizontal synchronizing signals, displayed on the display 7. At the same time, dots are counted by a counter 8, which is then input to a computer 9. The computer 9 takes in an output signal of a speed sensor 5, and operates total volume of soil based on the speed signal and the count of dots. The result is displayed on the display 7 and recorded by a printer 10.

摘要： PURPOSE:To exactly measure the level of sand by a method in which micro waves are transmitted from a transmitting antenna toward the face of sand in a cylinder, and reflected waves are received by a receiving antenna and processed on the basis of the time lag between the transmission and the receiving. CONSTITUTION:When micro waves M are transmitted from a transmitting antenna 16 toward a sand face 12a in the lower part of a cylinder 10, the waves M collide with the sand face 12a and the upward reflecting waves are received by a receiving antenna 18. On the basis of the time lag between the transmission and receiving of the waves M, the sand face 12a is measured for level by a processor 20 and the results are sent out to a displayer and a recorder. When the measurement is ended and sand 12 is charged, a protective case 14 is turned the axial direction of the cylinder 10 by an air cylinder 22 to protect the antennas 16 and 18 and the processor 20.

摘要： PURPOSE:To prevent a drain member from following to rise, by a method wherein a drain member is retained at the lower section in a mandrel, wherein a running unit for running on the surface of the drain member is firmly set, and wherein the running unit is run at a speed equal to that of lifting up the mandrel when it is lifted up. CONSTITUTION:A drain member 3 is fitted in a mandrel 1 and is driven into ground. After that, when the mandrel 1 is lifted up, then the caterpillar treads 11a, 11b of a running unit 5 are pressed on the surface of the drain member 3 and are run upward by the action of a driving wheel 10a connected to an air motor6. In this case, the detection signal of the rotational frequency of the driving wheel 10a, and signal corresponding to the rotation of an encoder 4 are fed to the comparing arithmetic operation section of a controller 21, and the signals are compared with each other, and an air flow quantity adjusting valve 9 is regulated so that the speed of lifting up the mandrel 1 may be equal to the speed of the running unit 5.

摘要： PURPOSE:To contrive improvement of efficiency in the driving-in cycle of a drain member by supporting the drain member in a vertically freely movable supporting member, energizing in the flaring direction and feeding the drain member with roller upon releasing the support of the drain member with a roller upon releasing the support of the drain member at the bottom position. CONSTITUTION:When the bottom end of the case 26d of the cutter 26 reaches the ground G, the cutter 26 retains its position and only the mandrel 12 penetrates into the ground G. Then, when the air cylinder 16 is extended, as the supporting plate 14 is energized in the flaring direction, the supporting plate 14a, 14a separates. The drain member 10 is released and simultaneously with the extracting of the mandrel 12, the roller 18 is rotatingly driven in the direction of feed out the drain member 10, thus preventing the co-rising of the drain member 10. In this way, without the need of lifting the mandrel highly, continual driving-in with the end of the mandrel slightly off the ground can be performed.

摘要： PURPOSE:To enable reduction of counting frequency of the apparatus and improvement of measuring accuracy, by arranging supporting points of the measuring tube in such a way that the supporting points can be distributed covering the longest distance. CONSTITUTION:A preliminary measurement is performed, by shortening an arm 22 of rotating rollers 20a, 20b, 20c on both ends and supporting a measuring tube 14 with supporting points in equal distance with the shortest distances, A1-A3. Next, from results of the preliminary measurement rough bend and radius of curvature of the excavating hole 24 are obtained and deviation of the axial direction of the hole 24 is examined and the longest distance L1+L2 of the supporting points relative to the deviation is determined. Next, the arm 22 is extended according to the distance L1+L2 between the supporting points and after changing the supporting points from A1 A1', and A3 A3' for the repeated measurement. Thus, as the distance between the supporting points has become longer as compared with that of the preliminary measurement, even if the bend of the same excavating hole 24 is measured, a drastic reduction of measurement frequency can be accomplished for decreasing the cumulative error and thus for improvement of the measuring accuracy.
