Abstract
PURPOSE: To prevent a small hole from clogging by a method wherein a cylinder is disposed movably within a porous chemical liquid feed tube to inject the compressed air from a small tube of the cylinder to the small hole perforated in the tube wall of said feed tube.
CONSTITUTION: A porous chemical liquid feed tube 1 and a bit 2 are provided for the point of the boring head. The porous inner tube is diposed within the feed tube 1 slidably, fixing the cylinder 5 having a hollow small tube 8 with the inner section of the porous inner tube. In passing the water to B passage under this condition, the compressed water is injecting from the point of the bit 2 to excavate the ground. Furthermore, in lowering the porous inner tube until the bottom end outlet of the porous inner tube reaches the stopper 3, the small hole 4 of the tube wall of the feed tube 1 coincides with the small hole of the porous inner tube. In feeding the chemical liquid from B passage, the chemical liquid allows to feed to the external ground by passing through the small hole 4. Next, in feeding the compressed air from A passage, the compressed air is injected from the hollow small tube 8 against the small hole 4 to prevent the small hole from clogging.
