Early summer season，Deep in the Taihang Mountains, 120 kilometers southwest of Beijing, mountains rise one after another.、It's green。Here，A large-scale water conservancy project with a total investment of more than 8 billion yuan constructed by the Fourth Bureau of China Water Resources——Hebei Yixian Pumped Storage Power Station，Construction is speeding up.。From the mountains more than 600 meters above sea level，To the underground powerhouse buried more than 200 meters deep.，All kinds of machinery and equipment rumbled on.，Advance the project process。

 

Since March this year，Yixian Pumped Storage Power Station Project has formally entered an important stage of two-way superposition of main civil construction and mechanical and electrical installation construction.。Construction on the ground of the reservoir，Above the high dam，Red and white Dynapac paver、The roller is quite eye-catching，They are working back and forth.，Carry out the asphalt concrete paving and compaction work of the dam surface in a tense and orderly manner.。

In water conservancy projects，The construction of asphalt concrete is a key link.，Its safety to the whole project、Stability and durability have an important impact.。Therefore, this special construction has very strict requirements for the performance of the equipment.，Thickness from paving、Consistency of width，Compactness and stability to compaction，Every detail determines the quality of the final project delivery.。

Dynapac pavers are equipped with an excellent independent hydraulic drive system.，It provides sufficient power reserve and strong traction for the construction of large slope surface.，The compact design of the fuselage makes the control more flexible and maneuverable.；Powerful track system provides good grip：Track shoe width up to 320mm，Track wheelbase up to 3.36 meters、Configure up to 11 roller，Bring absolute operational stability。These excellent characteristics ensure the excellent mobility of Dynapac paver in dam construction.。

In terms of paving capacity，The Dynapac paver's high-tech, four-axle-supported floating screed eliminates the need for tie rods.、Super resistance to deformation，Avoiding segregation while bringing uniformity、Stable、Uninterrupted spreading operation，The flatness of the dam surface is ensured.。

Behind the paver，Two DynapacCC1200VIDouble-drum road roller reciprocating up and down，High quality compaction of paving surfaces。Over 35°Inclined angle paving surface，CC1200VIThis high performance、High speed、The small steel gun roller with small tonnage is the most handy to work.。On the one hand，Dynapac High Frequency Vibratory Compaction Technology ensuresCC1200VIDo not lose the compaction capacity of large roller，On the other hand，The control characteristics of Xiaokuailing also ensure the construction safety and compaction efficiency.。High quality、Efficient、Ultimate Compactness at High Speed，It is the most important guarantee for the anti-permeability of the dam.。

The installed capacity of Yixian Pumped Storage Power Station in Hebei Province is as high as 1200 MW，It is a new generation of power system in Hebei Province.、Major projects serving energy transformation and economic and social development。The completion of the power station will have a far-reaching impact on the southern Hebei power grid.，O as to realize the task of power peak regulation and valley filling.，To provide a more stable and efficient power supply for the entire region。And，Hydropower is used to generate electricity，It will also play a huge role in promoting environmental protection and regional sustainable development.。

Dynapac with superior performance and quality，Continuously provide customers with all kinds of high-grade road construction schemes，Help you create more quality projects。Join hands with you，Build the future together！
