THICKENER FOR EXCAVATING SLURRY, EXCAVATING SLURRY USING THE THICKENER, AND CAST-INPLACE UNDERGROUND PILE WORK METHOD AND UNDERGROUND CONTINUOUS WALL WORK METHOD USING THE EXCAVATING SLURRY

摘要

A thickener for excavating slurry comprising alkali thickening emulsion. Independent claims are included for; (1) An excavating slurry using the above thickener with apparent specific gravity of 1.05 g/ml or more when measured immediately after strong stirring, and apparent specific gravity of 1.10 g/ml or more when measured 10 minutes after the strong stirring in a strongly stirring foaming test for a material obtained by adding alkali substance to the thickener; (2) Cast-in-place underground pile work method; and (3) Underground continuous wall work method using the excavating slurry,.
