[0002] A shaft is a common vertical transportation channel. As the main material for underground structures, the concrete conveying method largely determines the construction quality of the structure. For the concrete conveying of a shaft with a fixed discharge port, most of them use pipes to convey downward from the wellhead. During the concrete conveying in a high-vertical-distance shaft, the aggregate and slurry of the slurry are under different forces and have different moving speeds, which will cause the separation of concrete aggregates, affect the workability of concrete, and the pouring quality cannot be guaranteed. In addition, due to the relative movement between the slurry and the pipe wall, the aggregates and slurry impact the pipe wall, and the inner surface of the pipe wall is eroded and worn, and even the phenomenon of concrete pipe blockage occurs.
