Abstract
PURPOSE: Assured injection construction method is provided which is free from conventional flow due to undergraound water dilution.
CONSTITUTION: Double pipe rod, chemical feed pipe A is mounted with metal crown under and its external pipe diameter is contracted at the end, its internal pipe is cut at a slightly higher position. At the end of the rod A, chemical feed pipes are drilled directing at pipe wall and on the same axis of internal and external pipes. The external pipe hole B-1 diameter is made larger than the internal hole diameter B-2. Chemical injection device contains a two-stage piston body C which contactly slide at its upper portion along the internal pipe and at its lower portion along the narrowed external pipe E. Instantaneously fixing chemical is fed through the injection device.
