Abstract

PURPOSE:To make the compounding of chemical grout easier by a method in which slow-setting chemical grout and quick-setting chemical grout are supplied continuously and repeatedly by adding or stopping an assisting agent. CONSTITUTION:An injection tube 6 is set in the ground, and a quick-setting chemical grout prepared by mixing water glass or silica sol (A liquid) 1a with a hardener (B liquid) 1b is injected into apertures around the tube 6 and rough weak portion of the ground. On the way of the grouting, a slow-setting chemical grout prepared by mixing A liquid, B liquid, and an aid agent (C liquid) 1c is injected into the fine and dense portion of the ground. By repeating the adding and stopping of the C liquid, while switching the quick-setting grout and the slow-setting grout, the injection tube 6 is pulled out to solidify the ground. The ground can thus be easily improved by the composite grouting work.
