Abstract: A method and a device for treating soil, by injecting a treatment product, wherein a soil auger (51) with a helical drilling blade (512) in which an outlet opening (515) is provided is driven into the soil (7), while a treatment product is injected into the soil (7), the injection pressure (P) and the injection flow rate (Q) are measured, and the injection pressure (P) is adapted as a function of a soil parameter (Ks,rel) derived from the measurement values of the injection pressure (P) and the injection flow rate (Q). The device comprises a drilling rig (5), an injecting device (2a), (2b), (2c), a measurement device (3) and a computer (4).

Abstract: A method of treating soil adjacent a structure generally includes positioning a base unit of a treatment apparatus at a location adjacent the structure. An application tool is positioned over a first injection site. The application tool includes at least one nozzle. The base unit is operated to supply pressurized treatment liquid to the application tool. The application tool is operated to inject the pressurized treatment liquid into the soil at the first injection site without prior disturbance of the soil. The application tool is moved to a second injection site and operated to inject pressurized treatment liquid into the soil at the second injection site without prior disturbance of the soil.

Abstract: A device for treating soil includes a soil contact head having at least one discharge orifice therein, a handle attached to the soil contact head, a discharge valve in fluid communication with the at least one discharge orifice, a soil contact indicator, and a source of pressurized soil treatment fluid flowably connected to the discharge valve. The discharge valve discharges the pressurized soil treatment fluid through the at least one discharge orifice when the soil contact indicator indicates contact between the soil contact head and the soil.

Abstract: A hole forming tool is disclosed utilizing compressed gas discharged into a shaped shroud resulting in minimal disturbance to the surrounding ground.

Abstract: The invention relates to a device for removing plants or the like from the ground. The device comprises an elongated shaft, a ground support pivoted to a first end of the shaft transversely in relation to the longitudinal axis thereof and at least two blades including grip ends forming an extension of the shaft. The device is characterized in that the blades are pivoted in respect of the ground support transversely in relation to the longitudinal axis of the shaft and functionally connected together such that turning the shaft and the ground support in respect of each other causes the grip ends of the blades to move towards one another, thus enabling to grip the plant.

Abstract: There is disclosed an improved soil treating tool for the subterranean application of pesticides. The soil treating tool comprising an elongate body portion, a handle portion attached at one end of the body portion and an applicator portion attached to the other end of the body portion. The applicator portion is sized and shaped for insertion under soil and for forming an opening in the soil by lateral movement of the handle portion. The applicator portion defines at least one fluid outlet. A fluid inlet is provided in fluid communication with the applicator portion, such that fluid applied under pressure to the inlet is dispensed from the fluid outlet. A method for the subterranean application of pesticides is also disclosed.

Abstract: A multi-functional water jet weeder, cultivator, root waterer, and soil aerator device comprising a telescopic rod with an inclined handle grip, and having at least two inter-changeable spraying heads of different size with two rows of multiple metal spikes surrounded by water jets, combinable with a water hose having a quick disconnect unit at the opposite end of the device, and an on/off water control switch on the handle grip. A fertilizer or herbicide can be added by attaching a reservoir on the handle grip.

Abstract: An improved deep remediation injection system for in-situ remediation of contaminated soil and ground water. The system includes a soil penetrating lance for injecting at least two different highly-pressurized fluids taken from the group of air, gaseous oxygen, ozone, oxygenated liquid, hydrogen peroxide, surfactant-containing liquid, catalyst-containing liquid and suspended biologicals-containing liquids, or a liquid containing other chemicals, into said contaminated soil as said soil penetrating lance is inserted for penetration therein. The soil penetrating lance has at least an upper set of injection ports, the upper set of injection ports being generally radially spaced-apart on said lance, and at least one lower set of injection ports, the lance having an average width in the vicinity of the upper set of injection ports.
