From May 13th to 15th, the Distribution Network Technology Research Center of the Beijing Electric Power Company's Test and Research Institute conducted research on point measurement technology for cable tunnels beneath the parking lots of Olympic venues, in collaboration with four measurement product manufacturers: Unistrong, Laica, Topcon, and Trimble. This marked the beginning of precise measurement work for underground pipelines.

As the Olympics draw near, the task of ensuring power supply becomes increasingly important. With the improvement of urban economic development, the expansion of urban scale, and the rapid development of urban modernization, urban underground pipeline networks have become increasingly complex and extensive, with a growing variety of types. Currently, the Beijing power grid faces challenges such as incomplete underground pipeline network data and complex burial depths. Additionally, due to the deep burial and concealment of the pipeline network underground, it poses many difficulties for the construction and maintenance of the pipeline network. Therefore, there is an urgent need to strengthen the planning and management of the underground pipeline network. Traditional manual methods of collecting pipeline network data and drawing pipeline network maps are difficult to meet the real-time requirements of planning and management. Therefore, it is necessary to establish an underground pipeline network GIS to facilitate the entire process from pipeline network data collection, database establishment, to system function completion and assistance in underground pipeline network planning and management.
