Title:
INTRUSION SENSOR FOR INTRUSION TEST
Document Type and Number:
Japanese Patent JP3820364
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an intrusion sensor by which a frictional force acting on the side face of an intrusion body in an intrusion state, a total horizontal stress in a direction at right angles to a frictional surface and a pore water pressure can be measured and by which the frictional force and an effective horizontal stress can be measured simultaneously.
SOLUTION: An intrusion-body tip part 7 which is composed of a conical core fitting is installed at the tip of the intrusion body. The base end part of a cylindrical friction measuring part which is arranged on the outer circumference of an axial-force measuring part 6 is fixed to a friction sleeve 10 by a screw, and its tipe side is fixed to the tip part of the part 6 by a screw. A horizontal stress measuring part 2 is installed on the tip side and a horizontal stress measuring part 4 is installed on the base end side by sandwiching the part 1. A pore water pressure gage 3 is installed near the part 2, and a pore water pressure gage 5 is installed near the part 4. An X-direction clinometer 8 and a Y-direction clinometer 9 which are used to measure inclinations in two directions are installed. A stabilized power-supply part 19 is installed between the respective sensors and a measuring-device multicore connector 20 for external connection installed at the outermost base end.
