SOLUTION: Ready-mixed concrete C in a hopper 21 is continuously placed in a form 10 while transferring the hopper on the upper surface edges 13a, 14a of the form 10 by casters 22. Since a guide member 27 inserted in the placing space of concrete of the form 10 is formed at the lower end of the hopper 21, a concrete placing implement 20 is guided so that the concrete discharge opening is always positioned above the placing space. A concrete leveling member 28 installed at the lower end of the hopper 21 smooths the ready-mixed concrete C placed in the form 10 so as to scrape the upper face CF, in accordance with the transfer of the concrete placing implement 20.</p> |
