Huge concrete filled steel tubular column core grouting pouring and tamping device and method
The invention relates to a huge concrete filled steel tubular column core grouting pouring and tamping device and method, and belongs to the technical field of building construction. Problems that in construction of pouring and tamping a huge concrete filled steel tubular column core by using a multi-guiding-tube method, positions of a plurality of guiding tubes are not fixed in the horizontal direction, vertical lifting is not uniform, and heights are not determined are solved. The pouring and tamping device comprises a limiting plate and fastener clamps, wherein the limiting plate is inlaid in an upper port of a huge steel tubular column and is provided with a plurality of limiting holes; pouring and tamping guiding tubes can penetrate in the limiting holes; and the fastener clamps fixedly sleeve the outer walls of the pouring and tamping guiding tubes. The pouring and tamping method comprises the following steps: firstly, fixedly positioning the huge steel tubular column; secondly, mounting the limiting plate on the huge steel tubular column, arranging the fastener clamps and fixing seats on the outer walls of the pouring and tamping guiding tubes, and placing the pouring and tamping guiding tubes in the huge steel tubular column through the limiting plate; thirdly, pumping concrete in the huge steel tubular column through the pouring and tamping guiding tubes, and slowly and synchronously raising the pouring and tamping guiding tubes and vibration bar guiding tubes while pumping; and finally, detaching the pouring and tamping device after concrete pouring of the huge concrete filled steel tubular column is finished.
