摘要： PURPOSE:To provide a mine surveying device for surveying the mine buried under a ground with a non-destructive means in which a micro wave is applied onto a ground surface, a behavior of temperature at the ground surface after radiation is turned into an image so as to enable a presence or non-presence of the mine to be discriminated independently of quality of the mine. CONSTITUTION:A mine surveying device is constructed to have guide rails 6 mounted on a vehicle 19; a boggie 4 which can be moved along the guide rails 6; a micro-wave radiating device 1 installed on the boggie 4 so as to radiate a micro waver 24 against a ground surface 20; an infrared ray camera 2 installed on the boggie 4 side-by-side with the micro wave radiating device 1 and receiving an infrared ray got from the ground surface 20; and a mine discriminating infrared ray imaging device 16 arranged in a control chamber 25 of the vehicle 19 so as to receive the signal from the infrared ray camera 2 and projecting the infrared ray image. With such an arrangement as above, it is possible to perform a positive surveying of the mine even if an outer shell of the mine is not made of metal.

摘要： PURPOSE:To decide in a short time whether a mine exists or not and enable the application to a nonmetallic mine by radiating X rays against the ground surface, detecting gamma rays radiated from the ground surface and deciding the existence of the mine by means of a survey-meter on the basis of a detection signal. CONSTITUTION:In order to probe-and-handle a mine 19, a vehicle 12 is driven to a detection site, and then a truck 7 is moved forward to a specified detection area by means of an electrically driven cylinder 6. Then, high-energy X rays 21 are applied to the detection area for a specified period of time from an X-ray generating device 1. Gamma rays are detected by a detector 2 and a dose rate is measured by a survey-meter 14 so as to determine whether the mine exists or not. If the mine 19 does not exist in the specified detection area, the truck 7 is moved to a next detection area. If the mine 19 exists, jet water 2 is injected from a nozzle 4 of a water jet device 3 so as to remove soil around the mine 19 and an excavator 50 is used to dig out and remove the mine 19.

摘要： PROBLEM TO BE SOLVED: To investigate a buried object over a wide range by disposing a receiving antenna on an antenna case while disposing a pair of transmission antennas in the directions of electric field and magnetic field of a peripheral antenna and distributing the transmission output by means of a distributor. SOLUTION: A receiving antenna 5 is disposed in the center of an antenna case 17 and two transmission antennas 1, 3 and 2, 4 are disposed, respectively, in the directions of electric field and magnetic field of a peripheral antenna. The antennas 1-4 are fed with transmission pulses from a radar display 10 through a distributor 6 and an incorporated amplifier 29. A transmission wave radiated into the ground and reflected on a buried object is received by the antenna 5 and delivered through the radar display 10 and an A/D converter 11 to a personal computer 12 where it is displayed. The case 17 is turned, along with the antennas 1-4, about the fixing base 16 thereof by means of a motor cylinder 7 and the plane of polarization of the antenna can be altered. A truck is scanned in the direction of magnetic field and the case 17 turned by means of the cylinder 7. According to the arrangement, direction of the buried object can be matched with the plane of polarization of the antenna and a highly accurate investigation can be realized.

摘要： PURPOSE:To collect aggregates without being damaged, and what is more, prevent a cutter or the like from being damaged and repair with higher efficiency by boring a hole on a deteriorated asphalt with a spray device and filling water inside and then irradiating microwaves. CONSTITUTION:A rotary shaft 18 with a spike 15 is rotated so as to bore a hole on a deteriorated asphalt 1b. At that time, the rotary shaft 18 is rotated up to an arbitrary position by means of a reduction gear 19 where the penetration is repeated, thereby preventing the wear out of the spike 15. At that point of time when a limit switch 27 comes in contact with a truck 24 and halted there, a hole is bored to a specified depth and then water is sprayed with a water spray nozzle 29. Then, microwaves are oscillated with a microwave generator 5 and irradiated from the end of a waveguide so as to heat and soften a deteriorated asphalt 1c. This construction makes it possible to speed up heating/temperature increasing/softening operations, and what is more, bore holes simultaneously in a range equivalent to the width of a vehicle and eliminate such problems which involve wear of a chip and breakdown of a cutter and enhance work efficiency dramatically and reduce cost as well.
