摘要： PROBLEM TO BE SOLVED: To provide a constructing method for a tip-reinforcing cast-in-place pile, which brings about improved construction accuracy and working efficiency, and positively reinforces the ground near the tip of the pile.
SOLUTION: According to the method of constructing the cast-in-place pile, first a cage (2) having a steel frame (3) attached to the tip thereof is built in an excavated hole. The steel frame (3) has an injection bag (4) set on a bottom thereof. Then the steel frame is crushed by the pile bottom to expand the injection bag on the pile bottom, and a grouting material is injected in the ground with pressure, followed by pressurizing the ground in the vicinity of the pile tip. In the method, an injection pipe (20) for injecting the grouting material into the ground with pressure, and a slime discharging pipe (21), are each formed of a flexible rigid resin hose.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for a pile draft foundation for reducing an amount of settlement.
SOLUTION: A pile 14 is driven into the ground in a construction section. Next, the foundation 10 is directly installed on it so as to make a head of the pile 14 protruded out of a pile frame 12. A jack receiver 18 is joined with the pile 14 with a bolt 26. A method for joining the pile 14 with the jack receiver 18 may be the other method such as welding. After arranging a jack 30 between the jack receiver 18 and the foundation 10 directly, a force is applied in the direction for pulling out the pile 14 by the jack. A settling load (pre-load) is directly applied on the foundation 10 by a reaction force generated by a friction force on the peripheral face of the pile 14. Lastly, the foundation 10 and the pile 14 are directly connected and integrated to each other by a reinforcing bar 32 to construct the pile draft foundation for reducing an amount of settlement when a structure is constructed on it.
