GROUT INJECTION DEVICE
PROBLEM TO BE SOLVED: To provide a grout injection device that eliminates waste in labor and time when fitting an air vent pipe and ensures air removal at a time of grout injection.SOLUTION: A grout injection device 1 includes: a plug 2 to be fitted on a fitting jig 12 fixed on a through-hole 11 of an underground structure 10; a filling pipe 3 fitted on the plug 2 so that a first end and a second end of the filling pipe are positioned respectively on a first surface side and a second surface side of the plug 2, the filling pipe having a grout injection hose 15 fitted on the first end and an outlet 31 for discharging grout formed on the second end; and an air vent pipe 4 fitted on the plug 2 in parallel with the filling pipe 3 so that a first end and a second end of the air vent pipe are positioned respectively on the first surface side and the second surface side of the plug 2, the air vent pipe having the second end extending through a cavity S between the underground structure 10 and a ground 17 to a location in front of the ground 17.SELECTED DRAWING: Figure 4
【課題】エア抜きパイプの取り付けに要する労力や時間の無駄をなくし、グラウト注入時に確実にエア抜きを行うことができるグラウト注入装置を提供する。【解決手段】グラウト注入装置１は、地下構造物１０の貫通孔１１に固定された取付治具１２に取り付け可能なプラグ２と、一端及び他端がそれぞれプラグ２の一方面側及び他方面側に位置するようにプラグ２に取り付けられ、一端にグラウト注入ホース１５が取り付けられるとともに他端側にグラウトを吐出する吐出口３１を有する注入管３と、一端及び他端がそれぞれプラグ２の一方面側及び他方面側に位置するようにプラグ２に注入管３と並列に取り付けられ、他端が地下構造物１０と地盤１７との間の空洞Ｓを地盤１７手前まで延びるエア抜きパイプ４と、を備える。【選択図】図４
