Abstract
PURPOSE: To maintain sufficient strength against stress bending force as well as simplify the construction work of foundation pile by expanding the head of a pile to be driven in situ.
CONSTITUTION: An expanding auger is inserted into an expanded casing 2, and the ground is excavated by as much a depth (h) as the size of expanded head. In this case, boiling is prevented by keeping water level inside pit from which the expanding auger is drawn out higher than the level of ground water. By a standard auger 3, together with a standard casing of a length 1W2m longer than the size (h) of expanded head, excavation is made. While drawing out the standard auger 3 and the standard casing 4, cement mortar 5 is injected into the pit. And, a reinforcement 6 is inserted into the cement mortar, the standard casing 4 is drawn out, and the reinforcement 7 for the expanded head portion (h) is inserted and fixed securely.
