Drill hole plugging method utilizing sodium bentonite nodules

摘要: A method of plugging holes, in particular the drill holes earth. The utilizes a tubular capsule filled with coarse ground sodium bentonite. capsule, when inserted into hole, sinks through any mud or slurry material within hole to rest at bottom hole. If is overly dense material, rod may be used force capsules constructed water soluble and includes plurality slots cut along its exterior wall facilitate expansion allow liquid easily permeate container. plastic cap on upper end allows rods forced thereagainst push downward without puncturing capsule. Alternatively, layers sand interspersed bentonite nodules.
