发明名称 GROUND ANCHOR CONSTRUCTION METHOD AND GROUND ANCHOR STRUCTURE
摘要 PROBLEM TO BE SOLVED: To provide a ground anchor construction method and a ground anchor structure for compactly and economically performing construction and water cut-off. SOLUTION: This ground anchor construction method is constituted so that an anchor hole 4 is drilled in the artesian groundwater-existing ground 3 by a hole drilling pipe 5; grout 6 is filled in its inside by leaving the hole drilling pipe 5 in this anchor hole 4; a tensile material 7 is inserted into this grout 6; its upper part is led out from a hole drilling pipe upper end part; water is cut off by filling an accelerating agent 25 in clearance 12 between the upper outer periphery of the hole drilling pipe 5 and the anchor hole 4; and after hardening the grout 6 in the hole drilling pipe 5, the tensile material 7 derived from the hole drilling pipe upper end part is tensioned and fixed to an anchoring plate 18.
