This observation project is located in Zhangjiakou City, Hebei Province. Commissioned by Hebei Weizhou Energy Comprehensive Development Co., Ltd, our company undertook the deflection observation project of the spherical grid frame of the closed coal yard.
The spherical grid frame of the closed coal yard is a double-layer grid shell stereoscopic framework, with a length of 268.0m and a width of 10.6m. In this project, the elevation of the grid frame is measured by means of the triangular elevation measurement using the total station and the level meter, and the deflection deformation of the grid frame is calculated. The observation of the deflection observation point of the grid frame adopts the method of electromagnetic wave ranging triangular elevation measurement.
This observation project began on July 21, 2022, and was completed on January 12, 2023, in 175 days. The project was successfully accepted by the owner and the owner's data filing was completed.
