Abstract

PURPOSE:To make easier the injection work of grout by a grout injecting device having a system in which a quick-setting gelling agent and a slow-setting gelling agent are effectively injected into the ground to be strengthened. CONSTITUTION:Boring water is sent under pressure through a supply path 3 and a passage 7 and jetted from a jet nozzle 26 by pushing down a ball 28, and at the same time excavation is made by a bit 29 by turning excavating rods 1 and 2. When a main agent and a gelling acelerator are each supplied to supply paths 4 and 5, they pass through passages 10 and 9, reach a jet nozzle 8, enter through a thin film ring 12 into a thin film cylinder 14, and mixed there to form a quick-setting type gelling agent. The gelling agent is jetted from the slit 14a of the thin film cylinder 14 and permeated through a strainer formed by a coil 15 into the ground. When a slow-setting gelling agent is then sent under pressure from a supply path 6, it pervades through a thin film ring 12 into the thin film cylinder 24, is jetted from the slit 24a, and permeated through the strainer formed by the coil 25 into the ground.
