EQUIPMENT FOR POURING CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide equipment for pouring concrete, capable of restricting decrease in efficiency and rise in cost during concrete placement. SOLUTION: Concrete-pouting equipment 1 is for pouring a concrete 3 at the outer periphery of a pressure-resistant steel pipe 2 as an underground structure. This concrete-pouring equipment 1 is equipped with an upper hopper 10, a piping 11 and a valve 13. Upper hopper 10 is laid above the ground. The concrete 3 is supplied to the inside of the upper hopper 10 from a concrete mixer truck 5. One end portion 11a of the piping 11 is connected to the bottom end portion of the upper hopper 10, and the other end portion 11b is extended and distributed downward below the grade. The piping 11 is equipped with a plurality of pipes 11 connected to each other. Then valve 13 is located at least at one place along the piping 11. The valve 13 is able to introduce the outside air into the pipe 13.
