Amidst the mechanical roar deep in the Qinling Mountains, the construction pace of the Foping Pumped Storage Power Station in Shaanxi suddenly accelerated. With the official start of the construction of the upper reservoir dam, this project, which is regarded as a stabilizer for the northwest power grid, has finally completed a crucial turn from demanding earth and stone from the mountains to building a barrier to the sky. This is not only a rise in the dam body, but also a substantial elevation of the bottom line of regional energy security.

Reshaping the Engineering Aesthetics of Mountains

This massive structure, which is about to cross the mountains, adopts a concrete face rockfill dam design and is a typical hardcore project. The elevation of the dam crest is fixed at 1226.5 meters, with the highest dam reaching 90.5 meters. The length of the dam crest is 662.5 meters and the width is 8 meters, like a giant dragon coiling on the mountain ridge.

The most astonishing thing is the total filling volume of 2.777 million cubic meters. If these earthworks are laid into a standard football field, the thickness can reach tens of meters. The start of filling the upper reservoir means that the project has officially entered the sprint period of forming the main structure, and the dumping of each truck of stone materials is laying the foundation for future energy storage and power generation.

Digital algorithms crush every inch of the dam body

Unlike traditional crowd tactics, the filling site of the Foping project is filled with a sense of technology. In order to ensure the compactness of the rock mass is foolproof, the project team has introduced an intelligent compaction system. This system can monitor the number of passes, speed, and trajectory in real time, turning the roller into an intelligent robot.

The full process intervention of digital means not only controls the construction accuracy at the millimeter level, but also provides data endorsement for the safety of the dam. Under high altitude and complex geological conditions, this dual control of digital and physical is the key to ensure the stability of the 90m high dam as Mount Tai.

As an important puzzle for the consumption of new energy in the northwest region, the significance of Foping Pumped Storage Power Station goes far beyond power generation. It is more like a huge green power bank, absorbing electricity during peak periods and releasing electricity when there is no wind or light.Editor/Cheng Liting
