Abstract
PURPOSE: To reliably anchor a rock bolt by a method wherein the tubular rock bolt having a warp larger than an excavation diameter and having an uneven surface formed on an outer periphery is driven and is brought into frictional contact with an excavation wall to support the grouting reaction force of an anchoring agent. CONSTITUTION: Uneven surfaces 3 are formed at intervals of a specified distance on a pipe body. After an elastic tubular lock bolt 2 having at least one or more warp 4 larger than the diameter of an excavation hole 1 is lightly inserted in an excavation hole 1 formed in a ground, the lock bolt is driven in the excavation hole 1 by a driving machine 9 and forced into frictional contact with an excavation wall. A grouting pipe is inserted in the opening part of the rock bolt 2 and an anchoring agent is injected, the grouting pipe is pulled out, and through curing of an anchoring agent, a ground is stabilized. Further, before driving of the rock bolt 2, the anchoring agent is injected and the anchoring agent is injected through the rear end and/or the intermediate of the lock bolt 2.
