Abstract:
1. A method for washing contaminants from concrete chutes comprising: positioning a first concrete chute member such that a first end of the first concrete chute member is disposed above an opening in a container attached to a concrete mixing truck and the first concrete chute member is maintained at an angle such that a second end of the first concrete chute member is higher than the first end thereof and wherein the first concrete chute member has a “U” transverse cross-sectional shape; positioning a second concrete chute member having an open end adjacent the first concrete chute member, such that the open end of the second concrete chute member is higher than a second end of the second concrete chute member and such that fluid applied to the second concrete chute member flows through the open end onto the first concrete chute member which then flows from the first concrete chute member into the container, wherein the first and second concrete chute members are not coaxially aligned; and applying fluid to the second concrete chute member such that the fluid flows through the open end onto the first concrete chute member which then flows from the first concrete chute member into the container.
