Abstract
PURPOSE: To provide the stabilizing agent for excavation surfaces used in shield technique, continuous underground wall technique or the like and enabling safe and continuous excavation, by adding pulverized grass peat to bentonite or the like used as a principal agent.
CONSTITUTION: By adding pulverized grass peat to a stabilizing agent used for excavating an object ground by a fluid circulation method and employing bentonite or the like as the principal agent, the titled stabilizing agent for excavation surfaces is formed which has high film making properties and excellent strengthening ability and highly floating and dispersing ability for soil in the vicinity of an excavation surface, and provides the separated mud having a small water content.
