"Dam" gas! Liugong Unmanned Roller Helps the World's Highest Concrete Face Rockfill Dam

By the Jinsha River，Rawa Hydropower Station is rising.。This dam is not only the highest concrete face rockfill dam in the world.，And it's the country“Fourteen five”One of the nine key clean energy bases.——An important part of the clean energy base in the upper reaches of the Jinsha River。The total installed capacity of the power station reaches 2 million kilowatts.，The dam is 239 meters high.，Dam crest elevation 2709m。

Construction challenges

The Lawa Hydropower Station is located in the high mountains and valleys at the junction of Ganzi Prefecture, Sichuan Province and Changdu City, Xizang.，Complex terrain and extremely limited construction site。The foundation pit of the dam is 90 meters deep.，It is the largest project of its kind in China.，Bring great challenges to the construction。As of September，The elevation of the whole section of the dam has reached 2580 meters.，The monthly intensity of quarry excavation and dam filling exceeds 1 million cubic meters.，The dam rises more than 14 meters per month.，It is the concrete face rockfill dam with the fastest filling rate in China at present.。

Intelligent construction solution

Strict requirements for the quality of dam filling in areas with frequent geological disasters and strong earthquakes，The project uses Liugong unmanned roller to replace the traditional manual operation.。This not only solves the problem of low accuracy of manual rolling,，But also ensures the quality controllability of the whole process.。

Liugong 6636EUnmanned single steel wheel roller relies on its powerful power（294kWEngine）、Up to 810kNExciting force and excellent plateau adaptability.，Outstanding performance in the project。The equipment can easily cope with granite rockfill filling tasks with a single layer thickness of up to 1 meter.。In order to satisfy each layer 0.Standard ply thickness of 88 m，Multiple static and vibratory compaction operations are required。In addition，The Road Roller is made of high-strength material.，It is also equipped with a flexible vibration system and a large-sized slewing bearing.，O as to ensure the stability and reliability of long-time continuous work.。

Once completed，The Rawa Hydropower Station will provide about 82..2.4 billion kilowatt-hours of clean electricity，Equivalent to saving about 2.8 million tons of standard coal，Reduce carbon dioxide and other greenhouse gas emissions by about 9.1 million tons。This achievement is of great significance for promoting the development of the country.“Double Carbon”Achievement and further implementation of the objectives“Power transmission from west to east”The strategy is of great significance.。
