摘要： PROBLEM TO BE SOLVED: To make it possible to inhibit a stabilizing fluid containing a carbonate as a dispersant from being deteriorated by the Ca ions in an excavation work for a diaphragm wall, an earth drill pile or the like with the stabilizing fluid and to inhibit the formation of mud film on the cut concrete surface in a work of cutting the concrete or the diaphragm wall. SOLUTION: This method is one for administering a stabilizing fluid in an excavating work for a diaphragm wall, an earth drill pile or the like or in a work for cutting the concrete of the diaphragm wall with a stabilizing fluid wherein the excavation is performed while a stabilizing fluid containing a carbonate as a dispersant is being recirculated. The carbonate concentration and pH value of the fluid are monitored. An alkali hydrogen carbonate or an alkali carbonate is added to the fluid so that the carbonate concentration may not lower to 0.05wt.% or below (in terms of the sodium hydrogen carbonate), and the pH value may fall within the range of 8-13. Thus, the carbonate concentration of the recirculated fluid can be kept at 0.05wt.% or higher, and the pH value can be kept at 8-12.
