Apparatus for injecting soil conditioning fluid

An apparatus for injecting a soil conditioning fluid into a soil foundation comprising:

• an apparatus body having a water tank, a conditioning fluid tank, a pump for feeding at least water and conditioning fluid under pressure, and a switch valve for switching a first pipeline leading from said water tank and conditioning fluid tank to said pump;
• a boring machine located at a position spaced apart from said apparatus body and having a hollow rod with a boring device attached at a front end thereof, a front end of said hollow rod being formed with a discharging port for discharging the water and conditioning fluid fed under pressure from said pump, said boring machine and said apparatus body being interconnected by a second pipeline, said boring machine including
• (a) a planar base having guide rails on opposite sides thereof and a magnet fixture means for securing said planar base to a magnetic wall mounted thereon;
• (b) a movable base mounted on said planar base, said movable base being slidable along said guide rails and able to be secured in a desired position;
• (c) a slide base disposed on said movable base and having an axial guide rail extending in a perpendicular direction relative to a plane formed by said guide rails;
• (d) a slider engaged with and guided by said axial guide rail of said slide base and reciprocally slidable in said perpendicular direction and a hollow rod rotatably mounted on said slider and having a hole-saw type cutter at a front end thereof, said hollow rod being capable of injecting the soil conditioning fluid from a rear end portion thereof into the soil foundation through said cutter;
• (e) first drive means for rotating said hollow rod;
• and
• (f) second drive means for reciprocally moving said slider;
• and
• a control panel, capable of remote controlling said switch valve, formed as a separate body from said apparatus body.
