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

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 provide a non-cutting pipe burying method which introduces a strong hole drilling force to enable an obstacle to be penetrated to thereby enable drilling almost every sort of soil as planned, and which allows operations to proceed efficiently by grasping underground conditions in advance, leading to reductions in the period of construction and cost for entire burying work. SOLUTION: During a drilling operation using a drill bead 11, a fluid containing abrasives is ejected at high pressure toward an obstacle 34 under the ground which may be damaged, so as to drill the obstacle 34 and enable the drill head 11 to pass therethrough, so as to allow drilling through the obstacle 34 even if the obstacle 34 which cannot be penetrated by the drill head 11 alone is present on a planned line. Thus, the drilling operation can be performed without being interrupted by the obstacle 34 and the period of construction work can be reduced. Also, load applied to the drilling part of the drill head 11 is reduced to enhance the durability of the drill head 11.

摘要： PROBLEM TO BE SOLVED: To eliminate danger by preventing a hydraulic hose from jumping about owing to the reactive motion of the water stream spouting from the front end of the hose when the hydraulic hose fitted to a pile is drawn upward and is detached from the pile. SOLUTION: A valve body 7 is connected to the front end of a hydraulic hose 6 and a straight valve spool 8 is slidably fitted in the valve body 7. Meanewhile, a closed-end cylindrical valve holder 9 is fixed to the pile 1 and when the valve body 7 is inserted in the valve holder 9, the valve spool 8 is pushed up (A) and the pressure water is vertically connected through the valve spool 8 and spouted downward (arrow mark a). When the hose 6 is pulled up, the valve spool 8 is pushed down by the hydraulic pressure and a through hole 8b on the pipe wall is exposed and the pressure water is discharged also form the hole and hence, the jet water stream downward is weakened and the reaction is also lessened (B).
