摘要： A collapsible containment berm having a floor and a peripheral sidewall, a plurality of brace assemblies integrally carried on an external surface of the sidewall and on an adjacent underside surface of the floor, each brace assembly comprising a rigid sidewall support member connected to the external surface of the sidewall and oriented upright when deployed, a rigid buttress member having a first end and an opposite second end, and hingedly connected to an upper end of the sidewall support member that allows the buttress member to arc toward or away from the sidewall, a rigid floor member hingedly connected at the third end to the other end of the buttress member, and a sleeve connected to the underside of the floor and adapted to receive the floor member. The floor member slides in and out of the sleeve and moves the buttress member in and out of a bracing position with respect to the sidewall.
