[0033] With the rising of the concrete in the steel pipe column body 6, air enters the vertical pipe 11 from the air outlet 5 on the top plate of the steel pipe column body 6, then enters the hose 13, and is discharged to the outside. It can be guaranteed that all the air is discharged before the concrete is filled, the grouting quality is good, and the filling is sufficient.
[0034] After the concrete rises to the top of the steel pipe column body 6, grouting is still in progress, and when the concrete flows out of the exhaust pipe 1, it indicates that the air in the steel pipe column body 6 is completely discharged, and the concrete rises to the top and is completely filled.
