摘要： PROBLEM TO BE SOLVED: To provide a steel pipe expansion type rock bolt which shortens the length of a pressurized fluid injecting sleeve to clad the steel pipe expansion type rock bolt, minimizes a difference between a concrete thickness at a sleeve protruded portion and a concrete thickness of a peripheral portion, to thereby contribute to formation of highly reliable lining concrete. SOLUTION: In the structure of the rock bolt, the pressurized fluid injecting sleeve 10 is formed of a cylindrical large-diameter protrusion 11 and a small-diameter washer holding portion 12. Then a washer 6 is fitted onto the small-diameter washer holding portion 12 to hold the same, and a part of the washer holding portion, on one side of the washer toward a distal end is embedded in a rock bed. In this manner only the washer 6 and the cylindrical large-diameter protrusion 11 of the rock bolt protrude outward from the surface of the rock bed. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： A high-strength steel pipe rockbolt has an expansive rockbolt main body prepared by processing a high-strength steel sheet of 1.8-2.3 mm in thickness with a tensile strength of 490-640 N/mm2 and an elongation of 20% or more into a welded pipe and roll-forming the welded pipe into a shaped pipe having one or more concavities extending along an axial direction. Use of the high-strength steel sheet ensures sufficient strength of the shaped pipe regardless of a decrease in thickness. The thin welded pipe is also advantageous in resistance to cracking caused by accumulation of strains introduced during roll-forming, swaging both ends of the welded pipe and hydraulic expansion. Moreover, expansive deformation of the shaped pipe is initiated by injection of a pressurized fluid at a low pressure, so that the expansive deformation is completed in a short time period with an improved working efficiency.
