摘要

PROBLEM TO BE SOLVED: To provide a method of injecting grout which can prevent the quality of the grout from being lowered due to the injection thereof, in water, into the gap between a foundation pile and a part to be mounted, which can reduce a construction period, and which can be efficiently performed, a method of constructing a bridge using the method, and a foundation pile fixing structure applicable to the method.;SOLUTION: The method of injecting grout includes a step of attaching a flexible tube 11 and a water-cutout cover 12 to a driven foundation pile 1, a step of bringing the water-cutout cover into contact with the bottom end 16 of the part to be mounted 3 installed on the foundation pile and positioning the flexible tube near the lower surface of the water-cutout cover, a step of sealing between the bottom end of the part to be mounted and the water-cutout cover and between the foundation pile and the part to be mounted by inflating the flexible tube by filling air therein to press the flexible tube on the foundation pile and the lower surface 14 of the water-cutout cover, a step of discharging the water between the part to be mounted and the foundation pile, and a step of injecting grout between the part to be mounted and the foundation pile.;COPYRIGHT: (C)2012,JPO&INPIT
