摘要： PROBLEM TO BE SOLVED: To prevent lowering of cutting efficiency by burying a large number of cemented carbide made rod type tips harder than a parent material in the orthogonal direction against a cutting surface in the inside of the metallic parent material and forming a plural number of broken grooves along the overall circumference in the longitudinal direction with constant intervals respectively on the rod type tips. SOLUTION: A large number of cemented carbide made rod type tips 11 harder than a parent material 1 are cast in the orthogonal direction against a cutting surface in the inside of the metallic parent material 1. Thereafter, a plural number of broken grooves 12 along the overall circumference are formed with constant pitches in the shaft center direction within a surface orthogonal with their shaft centers on outer peripheral surfaces of the rod type tips 11. Consequently, edges on head end parts of the rod type tips 11 are rounded while cutting, before cutting efficiency drops, the rod type tips 11 are broken on the broken grooves 12 on the extreme head end sides by an autogenous blade function and new knife edges appear, and the cutting efficiency never drops. Additionally, even in the case when a more than specified load is applied on a cutting bit, the rod type tip 11 is broken on the broken groove 12 on the extreme head end side and impact can be absorbed, and it is possible to prevent breakage of the cutting bit itself.

摘要： PROBLEM TO BE SOLVED: To continuously excavate a buried object such as a soft layer, a hard layer and a steel material by implanting hard tips in a bit main body tip part on the tip of a rotary cutter ring by inclining the tip by a specific angle in the rotational direction. SOLUTION: A plan view rectangular blade part 3 is arranged on an excavating bit 1, and the excavating bit 1 is installed in a tip part of a cutter ring via a holder 5. Plural tips 9 forming a columnar shaft shape and being composed of a hard material are implanted in the blade part 3 by projecting from a tip part 3a of the blade part 3. The tips 9 are slantingly implanted so as to turn in the rotational direction T of the cutter ring as these proceed to the tip side of the blade part 3. The respective tips 9 are mutually inclined in parallel to each other, and an inclination θ formed in the direction vertical to a bottom surface 6b of an installing part 6 of a bit main body 2 is set to 3 deg. to 12 deg.. Since the tips are slantingly implanted, even if the tips 9 are abraded, a sharp shape is maintained on the rotational direction side, so that excavation of a semi-hard rock layer from a soft layer and excavation of a buried object such as concrete and a steel material can be reliably continuously performed.

摘要： PROBLEM TO BE SOLVED: To provide a method for finding the location of a buried magnetic object, which is capable of magnetic exploration in a location closer to a target and capable of, even when a building is on the ground, finding the exact location of a magnetic object buried under the building, through operation from the surface of a different location.
SOLUTION: The method includes: forming an exploration hole 25 near an target of exploration made of a magnetic material such as a tie rod 21 buried in the earth, by using a curved drilling machine for drilling while grasping the shape of a hole three-dimensionally; inserting, into the exploration hole 25, a magnetic sensor guide tube 24 constituted by a flexible tube made of a nonmagnetic material; then inserting a magnetic sensor 22 into the guide tube; measuring the intensity of magnetism by the magnetic sensor while measuring the insertion length of the magnetic sensor and measuring the location of the magnetic sensor in the exploration hole while moving the magnetic sensor; and thereby measuring the location of the target of exploration buried.
