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
