摘要： PROBLEM TO BE SOLVED: To provide a foaming agent for a foam shielding method, which has effects of reducing the excavation resistance and wear of a cutter head and enhancing the workability of excavated soil transportation treatment, which are equal to or more than those of a conventional product, and further has high stability at low concentration, and to provide a method for using the same.SOLUTION: The foaming agent for foam shielding method includes: a forming agent including a compound A represented by the following formula (I) and one or more compounds B selected from sorbitan fatty acid esters and polyoxyethylene sorbitan fatty acid esters; and water, wherein the mass ratio of A to B is 90.0/10.0 to 99.9/0.1. [R-O-(AO)SO]X (I), wherein Ris 8-20C alkyl or alkenyl, AO is a mixture of one or more 2-4C oxyalkylene groups, m is 0-50 as the average additive mole number of AO, X is a hydrogen atom, alkali metal, alkali earth metal, ammonium group, alkylammonium group or hydroxyalkyl ammonium group, and p is the valency of X.
