Outer layer ground treating device

Abstract

Abstract PURPOSE:To simplify the mechanism of a treating device and to reduce the cost and manhours of construction by successively moving an injection nozzle to desired positions on a ground area to be treated, with the use of a moving means, and by injecting a ground improving fluid into the ground under high pressure. CONSTITUTION:An injection nozzle part 2 is suspended from a hook mechanism 9 at the front end of an arm 8 provided to the front part of a control cabin 7 on a weak ground running vehicle 3. Further, by allowing the vehicle 3 to self-run on a weak ground 4 so as to move the nozzle part 2 which is then lowered to a predetermined position. A ground improving fluid 5 which is fed into the body 13 of the injection nozzle part 2 is injected under high pressure into the ground from the around surface through nozzles 16. Accordingly, the fluid is charged into the ground 4 while excavating the ground 4 surface.
