DETAILED DESCRIPTION

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figs. 1-3The utility model provides a kind of pile foundation concrete pouring construction hopper, including adjusting platform 3, the upper end face central of the adjusting platform 3 is equipped with hopper stable groove 31, for placing hopper 1.The height of the hopper stable groove 31 is slightly higher than adjusting platform 3, and is equipped with the slope matching with hopper outlet, so that hopper is placed in hopper stable groove 31 more stable.

[0020] The adjusting platform 3 is provided with height-adjusting column 4 on four corners, for adjusting the height of adjusting platform 3, the height-adjusting column 4 includes bottom plate 42, for supporting ground, can maintain the stability of the whole device, the bottom plate 42 is equipped with height-adjusting bolt 41, the lower end of the height-adjusting bolt 41 is rotationally connected with bottom plate 42, and the upper end penetrates adjusting platform 3, and the adjusting platform 3 is equipped with screw thread matching with height-adjusting bolt 41.In use, the purpose of adjusting platform 3 lifting can be realized by rotating height-adjusting bolt 41.
