Abstract:
PURPOSE: To provide a construction method suitable for construction of a pile reinforcement structure which removes ground around a pile and exposes a pile, and charges a reinforcement material such as an aggregate to a removed space and compacts the reinforcement material, and forms a reinforcement layer.CONSTITUTION: A construction method of a pile reinforcement structure in which a pile 2 is driven into ground 1, and a reinforcement layer is formed around the pile 2, includes preparing an auger 4 having a cylindrical part 5 whose diameter is larger than that of the driven pile 2, and a blade 6 formed on the circumference of the cylindrical part 5, and rotating the cylindrical part 5 while externally inserting it to the pile 2 and removing the ground 1 around the pile 2, filling the removed region with a reinforcement material, and reversely rotating the auger 4 while externally inserting the cylindrical part 5 to the pile 2.SELECTED DRAWING: Figure 3
