연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A device for treating soil has a soil contact head having at least one discharge orifice therein, and a handle to which the soil contact head is attached. A discharge valve is with the at least one discharge orifice, and a controller is provided for controlling operation of the discharge valve. An actuation trigger is included for initiating an injection event, with the controller being responsive to the actuation trigger to operate the discharge valve in response to the actuation trigger initiating an injection event. The controller controls the duration during which the discharge valve is open during an injection event in response to a single actuation of the actuation trigger. A source of pressurized fluid is flowably connected to the discharge valve, wherein the discharge valve is operable to discharge pressurized fluid through the at least one discharge orifice during an injection event.

1. A device for treating soil, comprising: a soil contact head, said soil contact head having at least one discharge orifice therein;a handle, said soil contact head being attached to said handle;a discharge valve in fluid communication with said at least one discharge orifice;a controller for controlling operation of the discharge valve;an actuation trigger for initiating an injection event, said actuation trigger disposed on said handle, the controller being responsive to the actuation trigger to operate the discharge valve in response to the actuation trigger initiating an injection event, the controller controlling the duration during which the discharge valve is open during an injection event in response to a single actuation of the actuation trigger; anda source of pressurized fluid flowably connected to said discharge valve, wherein said discharge valve is operable to discharge pressurized fluid through said at least one discharge orifice during an injection event. 2. A device in accordance with claim 1, wherein said soil contact head comprises a plurality of discharge orifices. 3. A device in accordance with claim 1, wherein said soil contact head has a bottom plane, and said at least one discharge orifice is angled with respect to said bottom plane. 4. A device in accordance with claim 3, wherein said discharge orifice is angled between approximately 5 degrees and approximately 30 degrees with respect to said bottom plane. 5. A device in accordance with claim 1, wherein said device comprises a plurality of discharge orifices, and an equal number of discharge valves, wherein each said orifice has a discharge valve associated therewith. 6. A device in accordance with claim 1, wherein the source of pressurized fluid comprises a source of pressurized soil treatment. 7. A device in accordance with claim 1 further comprising a soil contact indicator operable to indicate contact between the soil contact head and the soil, operation of the discharge valve in response to the actuation trigger initiating an injection event occurring only if the soil contact indicator indicates contact between the soil contact head and the soil. 8. A device for treating soil according to claim 7, wherein said handle comprises a first portion and a second portion, said first portion being slidable relative to said second portion, and said soil contact indicator comprises a contact sensing device attached to said first portion of said handle and a contact block attached to said second portion of said handle, wherein said discharge valve is operable to discharge pressurized fluid through said discharge orifice when said contact sensing device contacts said contact block as a result of said first handle portion sliding relative to said second handle portion. 9. A device according to claim 8, further comprising a biasing member, said biasing member resists sliding movement of said first handle portion relative to said second handle portion. 10. A device in accordance with claim 7, further comprising an electrical connection linking the controller to the actuating trigger, the discharge valve, and the soil contact indicator. 11. A device for treating soil according to claim 1, wherein said soil contact indicator comprises a force sensing device, said discharge valve being operable to discharge pressurized fluid through said discharge orifice when said soil contact indicator indicates a predetermined force between said soil contact head and the soil. 12. A method of injecting a soil treatment fluid beneath the surface of the ground, said method comprising: providing a soil treatment device comprising a soil contact head, the soil contact head having at least one discharge orifice therein, a discharge valve in fluid communication with the at least one discharge orifice, a handle, an actuating trigger disposed on the handle, and a source of pressurized soil treatment fluid flowably connected to said discharge valve;positioning the soil treatment device such that the soil contact head is in contact with the surface of the ground;actuating the actuating trigger to initiate an injection event;delivering the pressurized soil treatment fluid to the discharge valve; andinjecting the soil treatment fluid into the ground by opening the discharge valve to permit the soil treatment fluid to flow through the at least one discharge orifice and into the ground, the step of opening the discharge valve comprising controlling the discharge valve to open for a predetermined duration associated with a single injection event in response to a single actuating of the actuating trigger. 13. The method set forth in claim 12 wherein the soil contact head has a plurality of discharge orifices, injecting the soil treatment fluid into the ground comprising opening the discharge valve to permit the soil treatment fluid to concurrently flow through the plurality of discharge orifices and into the ground. 14. The method set forth in claim 12 wherein the soil contact head has a bottom plane, positioning the soil treatment device comprising positioning the soil treatment device such that the bottom plane of the soil contact head is in planar contact with the surface of the ground, injecting the soil treatment fluid into the ground further comprising directing the soil treatment to flow through the at least one discharge orifice at an angle with respect to the bottom plane of the soil contact head. 15. The method set forth in claim 14 wherein directing the soil treatment comprises directing the soil treatment to flow through the at least one discharge orifice at an angle between approximately 5 degrees and approximately 30 degrees with respect to the bottom plane of the soil contact head. 16. The method set forth in claim 12 wherein the device further comprises a soil contact indicator operable to indicate contact between the soil contact head and the soil, the injecting step further comprising opening the discharge valve to permit the soil treatment fluid to flow through the at least one discharge orifice and into the ground only if the soil contact indicator indicates contact between the soil contact head and the soil. 17. The method set forth in claim 16 wherein the soil contact indicator comprises a force sensing device, said injecting the soil treatment fluid comprises applying a predetermined force to the soil contact head; and opening the discharge valve to permit the soil treatment fluid to flow through the at least one discharge orifice when the soil contact indicator indicates the predetermined force between the soil contact head and the soil. 18. The method set forth in claim 16 wherein said handle has a first portion and a second portion, the first portion being moveable relative to the second portion, and the soil contact indicator comprises a contact sensing device attached to the first portion of the handle and a contact block attached to said second portion of said handle, and said injecting the soil treatment fluid comprises moving said first handle portion relative to said second handle portion to cause the contact sensing device to contact the contact block, and opening the discharge valve to permit the soil treatment fluid to flow through the at least one discharge orifice when the contact sensing device contacts the contact block. 19. The method set forth in claim 18 further comprising biasing the first portion of the handle against movement of said first portion relative to said second portion.
