摘要： PURPOSE:To carry out an economical and speedy work, by a method wherein a steel pipe pile is provided to be driven into a specified position and a slot of small diameter for a rock anchor is bored through and the rock anchor steel unit is set to be inserted into the slot and stressed after grout material is provided there. CONSTITUTION:A steel pipe 11 which is provided with a pile end stiffener 12 is driven aslant into a specified position, and after the pile end is cleaned, a guide pipe 16 is used to bore a slot 19 of small diameter for a rock anchor through. Then, a rock anchor steel unit 20 is inserted into the slot 19 through the head of the pile 11 and is set at a specified position, and the slot is grouted with mortar 27 also just under the anchor unit 20. And after the mortar is cured, the rock anchor steel unit 20 is stressed at the head of the pile and prestress is introduced into the anchor unit. As the result, wherever the place, the work can be carried out, and the proof stress of the anchor can be checked when it is stressed.
