ABSTRACT:
The truck has an hydraulic pump for receiving dredged mixture of solids and water from a pumping site and delivering the mixture to the truck body. A fixed partition wall is mounted transversely in the body and divides the body into first and second open compartments. The first compartment receives the mixture from the pump means to enable solids to settle at the bottom of the first compartment and the water rises towards the top of the compartment. The second compartment receives the water which rises in the first compartment and the partition wall. Drain means are selectively operable to effect removal of substantially all water from the second compartment. A one-way valve is located between the first and second compartments and is operable when the body is tilted to permit residual water in the second compartment to flow into the first compartment to effect removal of remaining solid matter from the first compartment by washing it out of the tilted body via the open tailgate.
