Verticality Detection Technology of Limited Space Large Formwork in Nuclear Power Projects
In the construction process of the civil engineering main structure for the nuclear island and the surrounding plant in the nuclear power project,the concrete walls and columns are generally tall and dense,and the quality of the formwork support will directly affect the quality of concrete pouring.The verticality detection technology of high and large formwork in limited space of nuclear power project is adopted.By setting up a special measurement control network in the construction area,a total station is set up on the control network.The retractable diamond mesh component is installed at the upper port of the formwork to fix the cross reflector.The formwork limit device is installed at the lower port of the formwork.The coordinates of the reflector are measured by the total station.The difference between the coordinates of the upper and lower ports of the formwork is compared,and the verticality of the formwork is judged according to the difference.The practice shows that the technology reduces the construction risk,saves the cost,shortens the construction period,and improves the construction efficiency and safety.
