And S2, extending a short pipe connected with the conveying pipe into the pouring opening.
And S3, pouring concrete into the steel pipe through the conveying pipe and the short pipe until the concrete rises to the water drainage port.
It should be noted that the preset height is determined by concrete of different types, and is usually the height of a floor, so that a worker can conveniently stand on the floor or an operation frame for construction.
It should be further noted that when the length of the steel pipe is greater than 2 times of the preset height, a plurality of pouring openings and a plurality of corresponding water drainage openings are formed in the outer wall of the steel pipe through the steel pipe, the height of each adjacent pouring opening is the preset height, and the pouring openings are sequentially poured from bottom to top during pouring.
According to the embodiment of the invention, the pouring opening and the water drainage opening are formed in the outer wall of the steel pipe at the preset height, the water drainage opening is positioned above the pouring opening, then the short pipe connected with the conveying pipe extends into the steel pipe from the pouring opening, and finally the concrete is poured into the steel pipe through the conveying pipe and the short pipe until the concrete rises to the water drainage opening. Through the method for pouring the concrete in the steel pipe, because the concrete is poured from the pouring opening with the preset height of the steel pipe when the steel pipe is poured with the concrete, the falling height of the concrete conveyed to the steel pipe through the water conveying pipe and the short pipe is not high, and then when the concrete is poured in the steel pipe, the concrete can be prevented from being segregated, and the quality of the concrete is ensured.
Specifically, when step S2 is executed, the specific execution process of step S2 is:
and the short pipe connected with the conveying pipe extends into the pouring opening at a preset angle, so that the discharge opening of the short pipe is lower than the pouring opening.
It should be noted that the short pipe connected with the conveying pipe extends into the pouring opening at a preset angle, and the discharge opening of the short pipe is lower than the pouring opening, so that when the poured concrete rises to the drainage opening, the concrete is prevented from reversely flowing out through the short pipe.
Preferably, the angle between the short pipe and the horizontal direction is 45-60 degrees.
It should be noted that the included angle between the short pipe and the horizontal direction may be 45 °, 60 °, or 55 °, which can be selected by those skilled in the art according to the requirement.
It should be noted that, because the included angle between the short pipe and the horizontal direction is 45 ° to 60 °, in order to ensure that the concrete can be smoothly transported to the short pipe, a bent pump pipe is arranged at the connection position of the short pipe and the transport pipe.
Further, referring to fig. 2, after step S3 is executed, the following steps are further included:
s4, judging whether the concrete is solidified, and if the concrete is solidified, executing the step S5; and if the concrete is not solidified, executing the step S4 after a preset time interval.
And S5, if the concrete is solidified, removing the exposed short pipe.
It should be noted that, because the exposed short pipe affects the overall aesthetic property of the steel pipe, the exposed short pipe needs to be removed, and the poured concrete is fluid, in order to avoid that the concrete in the steel pipe reversely flows out through the short pipe after the exposed short pipe is removed, it needs to first determine whether the concrete in the steel pipe is solidified through step S5, and after the concrete in the steel pipe is solidified, the exposed short pipe is removed through step S6, so that the concrete in the steel pipe can be prevented from flowing out.
Specifically, in the step S5, the step S5 includes:
and removing the exposed short pipe by adopting flame.
It should be noted that the exposed short pipe can be removed by flame, or by angle grinder, and those skilled in the art can select a suitable manner according to the requirement.
Further, referring to fig. 3, after step S5 is executed, the following steps are further included:
and S6, finishing and smoothing the concrete at the pouring opening.
And S7, welding a cover plate outside the pouring opening.
The concrete at the pouring opening is trimmed and smoothed, so that the concrete at the pouring opening can be attached to a repair cover plate welded to the outside of the pouring opening.
It should be noted that the concrete at the pouring opening may be uneven after being trimmed by the tool, and at this time, the concrete at the pouring opening may be smoothed by spraying cement mortar to the pouring opening, so as to be attached to the cover plate.
It is noted that the cover plate may be a material left after the pouring opening is opened.
Specifically, referring to fig. 4, before step S2 is executed, that is, before a short pipe connected to a conveying pipe extends from a pouring opening, the method further includes the following steps:
and S401, arranging a plurality of through holes at the connecting end of the short pipe and the water conveying pipe, wherein the through holes are arranged along the circumferential direction of the short pipe.
Step S402, sleeving the annular rubber sleeve on the through holes.
Before step S2 is executed, step S401 and step S402 may be executed in sequence, and then step S1 may be executed, or step S1 may be executed first, and then step S401 and step S402 may be executed in sequence.
Referring to fig. 5, after step S3 is performed, i.e. concrete is poured into the steel pipe through the conveying pipe and the short pipe until the concrete rises to the drainage opening, the method further includes the following steps:
and S501, respectively implanting a plurality of steel bars into the corresponding through holes to form the gate valve.
And step S502, disconnecting the delivery pipe from the short pipe.
It should be noted that a plurality of through holes are formed at the connection end of the short pipe and the water pipe, the through holes are arranged along the circumferential direction of the short pipe, the annular rubber sleeve is sleeved on the through holes, concrete is poured into the steel pipe through the conveying pipe and the short pipe until the concrete rises to the water discharge opening, the connection between the water pipe and the short pipe needs to be disconnected, and in order to prevent the unset concrete from reversely flowing out of the short pipe, a plurality of steel bars are respectively implanted into the corresponding through holes, so that a grid valve is formed (as shown in fig. 6).
It should also be noted that when the concrete is conveyed to the water outlet of the steel pipe through the short pipe by the conveying pipe, the ground pump stops conveying the concrete to the conveying pipe, the pump pressure is not reduced, the annular rubber sleeve outside the through hole is removed, the steel bar is implanted into the through hole of the short pipe, the ground pump is closed, and the connection between the conveying pipe and the short pipe is disconnected.
Further, referring to fig. 7, after step S3 is executed, the method further includes:
and step S701, vibrating the steel pipe.
It should be noted that, by vibrating the steel pipe, the concrete can be more dense in the steel pipe, and the strength of the solidified concrete is further ensured.

Further, after step S3, the method further includes:
step S702, judging whether the concrete in the steel tube is compact, and if the concrete in the steel tube is compact, executing step S703; if the concrete in the steel pipe is not compacted, step S701 is executed.
And step S703, stopping vibrating the steel pipe.
It should be noted that, in the case of determining whether the concrete in the steel tube is dense, the steel tube may be struck by a mallet, and whether the steel tube is dense may be determined by sound, or whether the concrete in the steel tube is dense may be detected by related equipment.
