Construction method for accurate steel pipe column installation
The invention belongs to the technical field of installation of steel pipe columns in engineering construction and aims at solving the technical problem that installed steel pipe columns easily shift and perpendicularity is influenced and providing a construction method for accurate steel pipe column installation. The construction method for accurate steel pipe column installation comprises the following steps of hardening the hole ground before construction, embedding U-shaped steel bar clamping grooves at the hardened positions corresponding to four corners of a well tower when the hole ground is hardened, clamping the well tower into the U-shaped steel bar clamping grooves when the well tower is installed, and welding the well tower and the U-shaped steel bar clamping grooves, arranging 15t mechanical jack at the position between the well tower and the hardened ground, then arranging a positioning device into a drilled hole, arranging the steel pipe columns in the positioning device, and respectively reserving 5 mm for the inner diameter of the positioning device and two sides of each steel pipe column body. By means of the construction method, the steel pipe column installation is performed, and the installing perpendicularity of the steel pipe columns is improved.
