When staking out super highrise building construction

it is important to analyze the horizontal coordinate precision of the control point of the axis. For coordinate transfer of control points of oblique super highrise buildings with high accuracy and precision

methods combining the electronic tachometer with laser aligner were adopted. The measurement sections were transited by sections many times on the floors. The coordinates of control points of lower floors gradually were transferred to the top floor by relays. We then could use the electronic tachometer to measure the linear distance between the control points of each floor and the control point of the axis

calculate the coordinates of the axis control point

and analyze the precision of the coordinates. Thus

integrated methods of transferring horizontal coordinates of super highrise buildings setting out of axis repeatedly can be taken from the control points to the monitoring points section by section. The precision integrated methods improve the coordinates of the control point of the axis by adopting advanced measurement equipment. We recommend choosing an electronic tachometer with different precision and a laser aligner to analyze the control point error quickly and accurately

provide a complete and systematic method for optimizing the stakingout scheme in construction

and guide the stakingout work and deformation monitoring work of super highrise buildings or oblique super highrise building construction.
