建立高精度施工控制方格网

Set up High Precision Control Squared Network to Construction

采用两级平面控制建立施工控制方格网的方法 ,充分遵从由总体到局部、以近为主、远近结合、多快好省的原则 ;体现便于施工、便于控制点保存、点位稳定的优点 ;保证施工控制方格网内精度均匀 ,便于扩展 ,为不同时期电厂建设奠定了可靠的基础 。

Using two levels control to build up the squared net in a power plant with large capacity units is necessary for this plant extend and ensure safety production.This paper introduced a way of that from overall to part,and precision evenly in net,as well as convenient for construction.
