The pouring quality of self-compacting concrete, as a key indicator to ensure the construction quality of steel tube concrete, has attracted particular attention.

[0003] In order to ensure the quality of steel tube concrete construction, the control of self-compacting concrete jacking is particularly important; the jacking construction process is a concrete vibration-free construction method that uses the pumping pressure of a concrete delivery pump to pour self-compacting concrete from the bottom of the steel tube column until the entire steel tube column is filled; in actual construction, it is often impossible to effectively prevent concrete backflow after pouring, resulting in cavities in the steel tube column, reducing the density of the concrete, which not only causes a waste of resources such as concrete, but also affects the safety of the structure and causes substandard construction quality.

[0004] Therefore, it is necessary to develop a self-compacting concrete pouring device that can solve the backflow problem during concrete pouring. Summary of the invention

[0010] In the above technical solution, a through hole is provided at the upper end of the rotating shaft, and the rotating handle is connected to the rotating shaft through the through hole; ball heads are provided at both left and right ends of the rotating handle.

[0026] The adjusting device 2 comprises an upper adjusting member 21, a lower adjusting member 22, a movable plate 23 and a rotating shaft 24.

[0030] The rotating handle 243 can move axially in the through hole 242 of the rotating shaft 24, so as to manually adjust the relative position of the rotating handle 243 and the rotating shaft 24. The rotating handle 243 is turned to drive the rotating shaft 24, and the internal and external threads can realize the up and down movement of the rotating shaft 24, thereby driving the movable plate 3 to move up and down through the lower end adjustment member 22, so as to realize the opening and closing function of the pipeline.
