摘要： PROBLEM TO BE SOLVED: To select a most appropriate position based on the information of internal conditions of hole by providing a borehole television(BTV) which can observe front and side simultaneously. SOLUTION: A water shield packer 12 for setting a test space, a BTV camera 15 for observing the inside of a borehole, and the like are disposed in the hole of a test equipment. The double-convex lens 30 and back-convex lens 31 in the camera 15 has a very short focal length and the imaging position is adjusted by varying the thickness of an intervening transparent spacer 32. A light beam from a forward object PF is condensed through the lens 30 and enters through the spacer 32 the lens 31, and since the focal point of lens 30 is located within the focal point of lens 31, the light beam is extended to produce an inverted virtual image. A light beam from a sideward object PS is reflected on the surface of lens 31 to produce a reflected virtual image PS' which is formed on a common plane CP together with the PS'. Consequently, the front and side images can be observed simultaneously over the entire circumference using a single TV camera disposed on one optical axis without altering the focal point.

摘要： PURPOSE: To reduce distributed soil in a region adjacent to a soil sample by gradually trim-removing soil in the bottom of a borehole with a trimming tool after drilling the borehole auger. CONSTITUTION: A borehole is drilled by an auger 1 having a removable nose cone. Next, a soil remover 5 is inserted to the auger 1 to fix to the auger 1 by a hydraulic clamp 2 fixed to a hydraulic cylinder 7. Next, a motor in a trimming tool 11 rotates a trimming blade about the axis of the hole and at the same time, the cylinder 7 is activated to gradually push the tool 11 and a casing 13 downward. In accordance with the tool 11 being advanced downward by this operation, the highest layer of soil is gradually timed or collected. Thus, it is possible to obtain a surface which is substantially vertical to the longitudinal axis of the auger and is practically smooth.

摘要： PURPOSE:To judge quality of soil at real time at the time of thrust by utilizing vibration which is generated at tip of excavation or minute vibration of rotary torque of a rotary excavator. CONSTITUTION:Hydraulic vibration of rotary torque of a rotary excavator 3 of a thrust tip device 1 which is thrusted in soil is detected by a pressure fluctuation detector 4. This signal is amplified, converted into a digital signal by an A/D converter 6, and sent to a digital computer 7. The computer 7 operates and processes information on the quality of soil based on the characteristics of waveform from the detector 4, and the result of operation is displayed on a display device 8 at real time to obtain information unique to the quality of soil which is scarcely affected by thrust. At this time, in the operation and processing of the information on the quality of soil which is executed by the digital computer 7, the quality of soil is judged in comparison with the characteristics which show the conversion value obtained by applying to the function of F(f, r, 1)=f*1/(r*mean(1)*10 in the abscissa and power in the ordinate. Here, (f) is a frequency of minute vibration of rotary torque, and (r) is the number of revolutions of the rotary excavator.

摘要： PURPOSE:To construct a foundation pit and permit the management with high precision in consideration of the state of each geological feature by judging the geological feature of the pile hole in excavation from the electric current value or torque value which is generated in pile hole excavation by utilizing the corresponding well-known geological feature. CONSTITUTION:An auger machine 5 is lowered, revolving the rotary rod 8 of a pile driver 1, and the descent quantity is detected by a depth meter 13, and the load electric current of a driving motor 6 is detected by a load electric current meter 12. Then, water is jetted from the top edge of the rotary rod 8, and a pile hole is successively excavated by an excavating cutter 9, and the excavation soil is made muddy by the agitation of the agitation rods 10, and the muddy soil is attached on the inner wall surface of the pile pit 14 by an attaching drum 11. Then, the load electric current and the output value of the depth are inputted into a CPU 14, and recorded and stored by a recording device 16, and displyed on a graph by a CRT 15. The geological feature representation is superposed on an electric current graph and displayed on a display device 15, and stored in a floppy disc, and the geological feature of the pile hole is judged.

摘要： PURPOSE:To simplify a hole in-situ test in the large depth by inserting a structure, to which pressure generating devices to drive a hole in-situ testing device are mounted as a unit, into a borehole. CONSTITUTION:A hole in-situ testing device 1 to which a penetration testing device 4, pressure generating devices 5 and 6, etc. are connected in series is lowered the inside of a borehole, and a reaction force plate 9 is operated through an oil pressure section 15 of the second pressure generating unit 6. Simultaneously, displacement is continuously detected by a reaction force dis placement detecting section 11. At the time of pressure welding of the front end of a piston penetrating section 8 to a hole wall opposite to the reaction force plate 9, the first pressure generating unit 5 is operated. The piston penetrat ing section 8 is driven in the direction of penetration and, at the same time, the pressure and displacement are detected, and ground data around the hole wall is transmitted to the ground from a telemetry circuit 7. According to the constitution, a penetration test of the large depth can be implemented by supplying power only to the hole in-situ testing device.

摘要： PURPOSE:To measure the water permeability and structure of the ground along a boring pit by installing pressure sensors among each packer section formed among packer sections disposed in a row and supplying one packer section with variable hydraulic pressure. CONSTITUTION:Three or more of pneumatic pressure interrupting packer sections 10... are arranged in a row at intervals, and pressure sensors 20... are mounted in a plurality of each packer section among the packer sections 10.... A water conveyance path having water permeability and being opened only in one arbitrary packer section is provided in the axial direction of a device. Each packer section 10... is expanded, and one packer section is supplied with variable hydraulic pressure through the water conveyance path from a variable hydraulic generating and feeding device 34. Variable hydraulic pressure with the change with time of a flow rate and responding pressure in another packer section to the variable hydraulic pressure are measured. The distribution of the coefficients of permeability in the horizontal and vertical directions of the ground distributed between a transmission packer section and a reception packer section is calculated on the basis of these values.
