Abstract
PURPOSE: To facilitate the working and maintenance by means of a spool valve so arranged in a vlave chamber provided in the outer valve separately from the pipe to make a cunter-flow combined stream.
CONSTITUTION: Charged with a spring, the spool valve 6 is maintained at the upper limit position different from that as illustrated except for the time of grouting and the second passage 10 and the guide hole 18 are communicated to allow water or the like to spout from the tip of the grouting pipe through the passage. At the time of grouting, the spool valve 6 is pushed down as illustrated with a grouting liquid Ga fed under pressure to the first passage so that the passage is communicated to a mixing chamber 14 by way of a discharge port 11 while the second passage 10 is communicated to the chamber 14 by way of a guide hole 15, a constricted section 17 and a discharge portion 12. Therefore, the grouting liquids Ga and Gb fed under pressure through the two passages are mixed as opposed in the chamber 14 and injected into the subsoil through an inlet 4.
