Novel concrete chute

The utility model relates to a novel concrete chute. The device comprises a plurality of tank bodies spliced end to end, a buffer groove is spliced at the bottom end of the groove body at the tail end; wherein the width of the buffer groove is consistent with that of the groove body, a plurality of flow guide blocks which are arranged in parallel are arranged in the buffer groove, the flow guide blocks are arranged in the flowing direction of concrete, the buffer groove is divided into a plurality of buffer areas by the flow guide blocks, and the sum of the widths of the buffer areas is smaller than the internal width of the groove body. One purpose of the utility model is that the multi-section groove body can be spliced according to the depth of the groove, so that the application rangeof the device is enlarged; and the bottommost buffer groove is provided with a flow guide block, so that the sectional area through which the buffer groove can pass is reduced, and the moving speed ofconcrete sliding to the b
