When the pouring position is changed, the wind-pulling rope 40 is loosened, the steel strand 31 is wound and unwound through the winch 32 to adjust the inclination angle of the supporting pipeline 11, and then the wind-pulling rope 40 is fastened. When the position close to the fixed support 21 is poured, as shown in fig. 1, the inclination angle of the support pipeline 11 is small, and pouring can be directly performed through the discharge hole of the diversion hose 13. When a position far away from the fixed support 21 is poured, as shown in fig. 5, the inclination angle of the support pipeline 11 is large, the height difference between the discharge port of the diversion hose 13 and the pouring surface is large, the diversion hose 13 can be placed at the top of the drainage groove 51, and pouring is performed by using the drainage groove 51, so that the pouring range of the chute system is expanded. After pouring is finished, the invention is dismantled.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
