Abstract | The invention discloses a concrete placing construction method for a steel pipe column core in a reverse construction method of a basement. The method includes the following steps: hanging a guide tube into a steel pipe column to be poured, plural sub-guide tubes forming the guide tube, each sub-guide tube being connected by screws; when the distance between the top of the guide tube and an opening of the steel pipe column reaches a preset distance, fixing the guide tube at the opening of the steel pipe column temporarily through a fixing device; hoisting a hopper vertically and connecting the hopper with the top of the guide tube; removing the fixing device; adding concrete into the hopper and starting pouring, drawing the hopper up and down by a crane so as to drive the guide tube to draw up and down and compact the concrete; when the concrete is poured a height of one sub-guide tube, stopping pour; temporarily fixing the guide tube again on the opening of the steel pipe by clamping the inferior of the firs |
