Title:
GROUND GROUTING METHOD AND INJECTION PIPE DEVICE
Document Type and Number:
Japanese Patent JP3889408
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a ground grouting method and an injection pipe device capable of preventing the difficulty of injection by making a boring wall collapse to bury a columnar space when the injection pipe is slantly horizontal or curved to insert it into the ground to prevent liquefaction.
SOLUTION: A plurality of bag bodies 4 are mounted to an exterior wall 2 of the injection pipe 1 at regular intervals, outer pipe discharge ports 5 are opened to the insides of the bag bodies 4 and between the bag bodies 4 and 4 vertically adjacent to each other, and an injection pipe device X covering the outer pipe discharge ports 5 with water permeable hole wall holding materials 8 is used. The injection pipe device is inserted in a boring hole 7 in the ground 6, the inside of each bag body 4 is filled with hardenable suspension to form a bag packer 3, and grout is injected through the holding materials 8 from the outer pipe discharge ports 5. The collapse of the boring wall 9 is thereby prevented.
