UNDERGROUND FIXING CONSTRUCTION METHOD FOR CONCRETE PILE, AND UNDERGROUND FIXING CONCRETE PILE USED FOR SAME CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an underground fixing construction method for concrete piles, and a concrete pile in which the concrete pile buried in the ground are jointed and integrated with soil around it to form a stable foundation without causing uneven settlement, and in which construction can be easily and speedily conducted to shorten a construction period and save construction cost. ;SOLUTION: A pile body, as this concrete pile 1, comprising an axially extended feeding conduit 13, and injection ports 14 opened in the outer circumference of the concrete pile 1 at a constant interval to be communicated with the feeding conduit 13 is buried in the ground in a construction section, soil hardening agent C is force-fed from the feeding conduit 13 to be injected through the respective injection ports 14 into soil L around it to penetrate it for hardening the soil L, and the hardened soil F around the concrete pile 1 is jointed and integrated with it, thereby it is fixed in the ground.;COPYRIGHT: (C)2001,JPO
