Layer membrane cleanner for eradicating to additivity water into ready mixed concrete

摘要

PURPOSE: A double layered cleaning cover membrane is provided to maintain a hoper and a chute being cleaned after pouring concrete at a construction field without washing the dirty hopper and the chute preventing a jerry-building due to addition of water into concrete. CONSTITUTION: The cleaning cover membrane consists of two layers bonded with an adhesive therebetween. The cleaning cover membrane is attached to a hopper installed at a rear portion of vehicle and a chute so as to be removed with a certain force. Through the hopper and the chute, concrete is poured to establish a constructional structure so that the hopper and the chute are to be dirty. To clean the dirty hopper and the chute, the cleaning cover membrane is just removed with a certain force instead of washing the chute and the hopper, maintaining the hoper and the chute being cleaned after pouring concrete, which prevents a jerry-building due to addition of water into concrete.
