| PROBLEM TO BE SOLVED: To provide a drill bit shaft structure of a drilling unit, which enables the bending of a drill bit shaft without generating great bending stress or deteriorating stress transferability. SOLUTION: In this drill bit shaft structure of the drilling unit 1, a part of the hollow drill bit shaft 2 is constituted throughout a predetermined length as a thin-walled shaft part 21 thinner-walled than shaft parts 22 and 23 on both sides. A tubular body 30 equipped with a universal joint structure is arranged in the state of surrounding the thin-walled shaft part 21. Both ends (32 and 33) of the tubular body 30 are connected and fixed to adjacent parts 22a and 23a of the shaft parts 22 and 23 on both the sides of the thin-walled shaft portion 21, respectively. The thin-walled shaft part 21 and the tubular body 30 are bent to enable the control of a drilling direction. COPYRIGHT: (C)2010,JPO&INPIT | ||||||

| PROBLEM TO BE SOLVED: To efficiently drive a thrusting body in a simple thrusting control. SOLUTION: This thrusting body is constituted of a thrusting main body 3 equipped with a thrusting head 1 provided with a pressure-receive face F tilting against the axial center P of the head and a plurality of thrusting pipes 2 connected to the rear side of the thrusting head 1. A plurality of bending connection parts R1 and non-bending connection parts R2 are formed at every longitudinal distance on the thrusting main body 3. Respective bending connection parts R1 are formed so as to be bendable only around one bending axial center X extending along the radial direction of the thrusting main body 3. And a positioning structure 13 is provided so that the mutual bending axial centers X of both bending connection parts R1 positioned at both sides of the straight connection parts R2 show parallel postures to each other, in accordance with the connecting works of the straight connection parts R2 to the bending connection parts R1. | ||||||

| PURPOSE: To dispense with a job for joint joining work as well as to prevent a leak of water from occurring by bending each of long strip underground pipes consisting of a plastic material successively, joining their side ends together, and inserting each one into a buried hole for propulsion forward as molding an endless underground pipe there. CONSTITUTION: A leading body 10 is pushed forward in the ground from the side of a vertical shaft V, forming an underground pit there, while a propulsion supporter 20 is successively connected to the rear of this leading body 10. At the vertical shaft V, an underground pipe 62 is fed to a guide roll 74 and a cylinder machining unit 76 from two bending rolls 71, 72, forming an endless underground pipe 60. In addition, this pipe 60 is locked to a supporter 20 by an expansion mechanism 50, and then it is pushed forward in an underground hole. COPYRIGHT: (C)1991,JPO&Japio | ||||||

| PURPOSE: To reduce torque required to rotate a drill string by forming at least one spiral groove on a main body part of a drill string member, so that the spiral groove defines a land on the main body part during flight. CONSTITUTION: A drill string member 14 is defined by an inside diameter 28 and an outside diameter 30, and has three spiral grooves 24. Residual parts of continuous lines are called lands, and they are parts of the member 14 to make contact with a bore hole in using. Compression stress is give to a surface 32 of the bottom part of the groove 24 by shot peening, etc. Consequently, mud moves around a drill string, and it is possible to improve a stirring effect and to extensively improve efficiency of drilling work. | ||||||
