GROUND INJECTION BOARD AND GROUND INJECTION METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a new ground injection board, with which a drilling process may be omitted, for replacing conventional injection tubes used in chemical feeding and other methods, and a ground injection method using the board.SOLUTION: A ground injection board, which is installed underground and used for sending chemical and other injection materials and discharging them into gaps in the ground, is made of thin, flexible strips of plastic and other water-impermeable materials. A plurality of long holes 12 for sending injection materials are formed within the thickness of the board in the longitudinal direction, along with injection ports 13 connected to the long holes 12 from which the injection material flowing through the long holes is discharged outside, installed at a plurality of locations on both sides or a side of the board. Also provided is a guide member 2 inserted into the long hole 12 from the injection port 13 for leading the injection material flowing through the long hole outside.
【課題】従来の薬液注入工法などで用いられている注入管に代わる新規で削孔作業を省略できる地盤注入ボード、及びそれを用いた地盤注入工法を提供する。【解決手段】地中に打設した状態で薬液等の注入材を移送して地盤の間隙に吐出するために使用される地盤注入ボードとして、プラスチック等の非通水性材料で形成された可撓性の細長い板状からなり、長手方向に延びた複数の注入材移送用長孔１２を板厚内に形成していると共に、両側面又は片側面の複数箇所に設けられて長孔１２に通じて該長孔に沿って流れてくる注入材を外へ吐出させる注入口１３を有している構成である。また、注入口１３から長孔１２内に配設されて、その長孔に沿って移送されてくる注入材を外へ導くガイド部材２を有している構成である。【選択図】図１
