摘要： PROBLEM TO BE SOLVED: To establish a technical means to dispense with a core removing work of a diamond core drill, and to improve the working efficiency. SOLUTION: A crevice 4 part larger than the core diameter is provided on a cylindrical shank except a welded part of a diamond bit 1 to a power connection part, and the advancing core is freely discharged. In feeding a refrigerant, a cylindrical article 3 is fixed to and embedded in a groove part by machining a groove in the cylindrical shank, and the refrigerant is fed to a tip of the diamond bit 1 through the cylindrical article.

摘要： PURPOSE:To perform grout injection work directly after completing drilling simply and easily, so as to remarkably improve working efficiency. CONSTITUTION:This drilling device is constituted so that a rotary casing 7 internally provided with an air supply pipe is hung and connected with an elevatably supported rotational drive device 4 through an air swivel mechanism 6 so as to be rotatably driven, and an air hammer 8 driven by air supplied through the air supply pipe is connected to the lower end part in the rotary casing 7 integratedly rotatably. After the ground is drilled by decided depth, grout supplied from the interior of the rotational drive device 4 through a grout supply passage separately provided from the air supply passage in a rotary shaft body 9 penetrating the air swivel mechanism 6 and a grout supply pipe provided in the rotary casing is injected into the drilled hole.

摘要： PURPOSE:To lengthen setting sizes of internal and external pipes and to reduce a number of complicated extention works by placing an earth moving rotary joint always on an upper side than a slider, and limiting a height of placement of the earth moving rotary joint with the ceiling on the slider. CONSTITUTION:An air outlet pipe 6 of an air supplying rotary joint 5 is connected to the base end of a guiding internal pipe 1 and the base end of an adding internal pipe 4 adding thereto, and an earth moving inlet pipe 11 of an earth moving rotary joint 10 is connected to the base end of a guiding external pipe 8 and the base end of an adding external pipe 9 adding thereto. Both internal pipes 1 and 4 are fitted to the insides of both external pipes 8 and 9, and the air outlet pipe 6 is interlocked and connected with the earth moving inlet pipe 11 through a rotary conduction 13 so that it is capable of rotating and interlocking. The guiding external pipe 8 and the adding external pipe 9 are constrained to a chuck mechanism of a slider 15 in a boring machine 14 to bore a hole.

摘要： PURPOSE: To facilitate handling operations and to achieve high-quality electric conduction by supporting pipe-shaped conducting means in such a way as to be concentrically extended with respect to other pipe elements. CONSTITUTION: Pipe-shaped conducting means 12, 12 are supported in such a way as to extend concentrically with respect to other pipe elements 21, 22 inside a pipe assembly 20 which constitutes a production pipe system or a drill pipe system. At their connection, a pipe element 1 for insertion is placed between standard pipe elements 21, 22 and their respective threaded parts 24, 25 are threadably engaged to ensure an electrical connection therebetween. Therefore the conducting means 12, 12 provide high-quality electrical conduction and the other pipe elements 21, 22 can be made to work as the liners of the conduction means 12, 12.
