摘要： PROBLEM TO BE SOLVED: To provide a method for measuring the drilling direction of a horizontal drillhole in the ground.
SOLUTION: The method for measuring the drilling direction for the horizontal drillhole in the ground includes providing a drill rod having a rod body and a direction sensor; setting the length of the hole for one process which is obtained by dividing the overall length of the horizontal drillhole into a plurality of lengths; drilling the hole by the hole length of the one process while driving the drill rod back and forth; stopping the drill rod; subsequently moving the drill rod back by the hole length of the one process or more; and measuring deviation from a straight direction with the direction sensor while moving the rod forward again up to the tip of the drillhole.

摘要： PROBLEM TO BE SOLVED: To solve the following problem that, conventionally when a hardener is diagonally or horizontally injected, a pump of standard performance cannot exert sufficient injection pressure and a discharge amount, resulting in insufficient injection, and in order to enhance the injection pressure and the discharge amount during the injection of the hardener into the target ground, a special high-performance pump at a cost equal to three times or more the cost of a standard pump is required.
SOLUTION: There is provided a multi-injection nozzle 3 composed of a core nozzle and circumferential nozzles enclosing the same, and the nozzles are connected to injection material feeding channels 2a, 2b, etc. , respectively, which then have respective high-pressure pumps arranged therein. Upon the simultaneous pressurization of the pumps, the injection materials are injected in a multi-overlapping manner, and therefore injection pressure of each injection material becomes synergistic, to thereby enhance the injection energy of high-pressure jet of the injection material in the target ground.

摘要： PROBLEM TO BE SOLVED: To solve the problems of producing waste that a specially injected hardening material is discharged as slime, and thinning a built-up hardening material layer, since excessive suction may be caused, when ground internal pressure of the object ground exceeds a predetermined value, though conventionally an arrival distance of a hardening material jet is extended and the ground internal pressure is adjusted by sucking the generating slime when injecting a ground hardening material. SOLUTION: An adjustably opening-closing shutter 55 is attached to a slime suction hole 5. A ground internal pressure measuring sensor 54 is arranged in a rod tip part. Slime suction corresponding to an internal pressure variation in the object ground by injection pressure of the hardening material, is performed by adjusting opening and closing of the shutter, and the excessive suction is prevented, and proper slime suction force is held.

摘要： PROBLEM TO BE SOLVED: To provide a method for controlling a direction in horizontal drilling which is available in a soil improving method depending on high-pressure injection. SOLUTION: In implementing the method for controlling the direction in horizontal drilling, there is provided a drill rod which is comprised of a cylindrical rod main body having a wedge-like tip, and an overcut bit attached to a peripheral surface of the rod main body in the vicinity of an apex of the tip portion. When no deviation from a straight forward direction is sensed, the rod main body is oscillated in a range of a first oscillating angle with respect to a predetermined orientation as a center of the first oscillating angle while being drilled forward, to thereby advance the rod main body in a straight forward direction. On the other hand, when deviation is sensed, the rod main body is oscillated in a range of a second oscillating angle with respect to an orientation opposite to a deviating direction as a center of a second oscillating angle, while being drilled forward. In this manner, the drilling direction of the drill rod can be corrected. COPYRIGHT: (C)2003,JPO
