HIGH-PRECISION AUTOMATIC POSITIONING AND VERTICALITY ADJUSTMENT SYSTEM FOR ULTRA-LONG STEEL COLUMN BY REVERSE CONSTRUCTION METHOD AND CONSTRUCTION METHOD

摘要

An automatic positioning and verticality adjustment system (100) and a construction method therefor, comprising a support (110), an automatic positioning and clamping device (120), a first detection device, an adjustment device (130) and a control device. The support (110) comprises a first platform (111) having a first through hole (1111) and a second platform (112) having a second through hole (1121); the first detection device detects vertical status information of an ultra-long steel column (200); the adjustment device (130) is used to adjust the position of the ultra-long steel column (200); and the construction method comprises the steps of placing the ultra-long steel column (200) into a pile hole, placing the support (110), clamping the ultra-long steel column (200) by means of the automatic positioning and clamping device (120), detecting the vertical state information by means of the first detection device, controlling the movement of the adjustment device (130) by means of the control device, and so on. The present automatic positioning and verticality adjustment system (100) may achieve the high-precision control of the position, axis positioning and verticality of the ultra-long steel column.
