Abstract
PURPOSE: To provide a concrete conveying method, which is capable of feeding concrete to a low place at a constant speed and without causing separation of concrete, by controlling flow resistance of concrete in the conveying pipe through provision of a valve means in said pipe.
CONSTITUTION: Concrete conveying pipe 2 is provided with a valve 18 at its upper end and a valve means including hinge 21 at its lower end. Weight 8 connected to said valve means applies its moment to the top of pipe 2 for closing the pipe 2 with cap 6. When concrete is dropped from hopper 1 and fills up concrete conveying pipe 2, cap 6 is opened automatically so that concrete is dropped smoothly through chute 10 to the place where it is to be poured, by its own weight and without causing separation of the same, while it is acted by flow resistance in pipe 2. On the other hand, in case that pipe 2 is choked or clogged, valve 18 is closed and water is fed under pressure into pipe 2 from water ejecting pipe 19 so as to force concrete loaded in pipe 2 to the outside thereof.
