When the constructional column concrete is poured to the bottom of the horn mouth turnover type concrete pouring hopper 35, the turning plate turning fixing bolt 55 is pulled out, so that the concrete feeding hole turning plate 59 falls down to plug the concrete feeding hole, and then the micro concrete with the residual height at the top is poured manually. And after the concrete pouring is finished and is stopped for a period of time, the self-tapping is removed, the horn mouth turnover type concrete pouring hopper 35 is pulled out, and the concrete is cleaned and then is used in a turnover mode.

The bell-mouth turnover type concrete pouring hopper 35 is in a bell-mouth shape with a large upper opening and a small lower opening, a fixed hanging lug is arranged at the upper end, a shelving shelf is arranged at the lower end, and a turning plate is arranged at the position of a concrete feeding hole so as to facilitate the fixation of the pouring hopper, the feeding and the sealing after the material is full; wedge-shaped anti-corrosion wooden wedges 34 are plugged into the wall body reserved plugging space at the top of the constructional column, the effect of fixing the pouring hopper hangers is achieved, the opening of the constructional column cement formwork plays a role in placing the pouring hopper and placing the shelf, and the feed port plate turnover device plays a role in plugging concrete feeding and full material.
