Concrete jacking construction method for steel pipe column
The invention discloses a concrete jacking construction method for a steel pipe column. The concrete jacking construction method for the steel pipe column comprises the following steps that a jackinghole is formed at the position of +0.5m at the bottom of the circular steel pipe column, a short pipe is welded at the jacking hole, the short pipe is connected with a concrete conveying pipe througha snap ring, and a circular plate cut at the jacking hole of the circular steel pipe column is numbered and reserved; a mounting hole with the size of phi 25 is formed in the short pipe at the distance 100mm from one end of the snap ring, and a check valve is mounted at the mounting hole; during concrete jacking construction, an overflow pipe is connected to an exhaust pipe; and after concrete pumping and jacking are finished, the circular plate is welded back to the original position according to the number. According to the concrete jacking construction method for the steel pipe column, thecompactness of the concrete can be effectively ensured, the construction safety is improved, and the construction cost is favorably saved.
本发明公开了一种钢管柱混凝土顶升施工方法，包括以下步骤：在圆形钢管柱底部+0.5m处开设顶升孔，顶升孔处焊接短管，并将短管与混凝土输送管用卡环连接，对圆形钢管柱上顶升孔处割下的圆板进行编号并保留；在短管上距离卡环一端间距100mm处开设大小为φ25的安装孔，将止回阀安装在安装孔处；在砼顶升施工时，在排气管上连接溢流管；待泵送顶升混凝土完成后，把圆板按照编号对应的焊接回原位。本发明能够有效确保混凝土的密实度，提高施工安全性，且有利于节约施工成本。
