Title:
MUDDY SOIL SOLIDIFYING TREATMENT APPARATUS
Document Type and Number:
Japanese Patent JP3628880
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a muddy water solidifying treatment apparatus capable of efficiently removing the muddy soil adhered to and deposited in the spaces between agitating vanes and screw vanes without any manual work.
SOLUTION: When the adhesion of the muddy soil in a half solidified state into space parts between the agitating vanes 31 and the screw vanes 32 is known, an operator switches a selector valve 42 in an arrow (a) direction. The compressed air from a pump unit 40 is then admitted into the device and extrusion bags 34 are expanded to move mud displacing plates 33 to the inner side in a diametral direction, by which the muddy soil in the half solidified state adherend to and deposited in the spaces is completely discharged from the spaces.
