The relevant person in charge of the Eighth Bureau of Hydropower said.，The core sample is taken from dam section 15.，Through field observation，The surface of the core sample is smooth and compact，The aggregate is evenly distributed，The structure is dense and has no gap.，Excellent interlayer bonding。The length of the core sample taken out this time also set a new world record.。

According to introduction，TBThe hydropower station is located in Diqing, Yunnan.，It is the upper reaches of the Lancang River.“One library, seven levels”The fourth cascade power station in the development plan，The total length of dam crest is 477 meters.，The maximum dam height is 158 meters.，It is the highest RCC gravity dam under construction in China at present.，Total installed capacity 1.4 million kilowatts。

The relevant person in charge of the Eighth Hydropower Bureau said.，AtTBThe hydropower station is under construction，Team makes full use of intelligent rolling、Intelligent temperature control、Intelligent grouting、Smart Material、Intelligent mixing、Six systems for general application，Realize concrete warehousing、Rolling、Real-time monitoring of the whole process of maintenance，The concrete construction quality of the dam is effectively ensured.。

The official also said.，The team is already inTBMany RCC construction records created in the construction of hydropower station，Include“The maximum pouring lift is 18m”“The maximum daily pouring output is 11800 cubic meter”Etc。
