Recently, the first unit of Toba Hydropower Station, the fourth step power station in the development program of "one reservoir and seven steps" in the upper reaches of the Lancang River main stream that our company participated in the construction of, has successfully completed the 72-hour test run and was officially put into operation to generate electricity, which marked the official completion of the only large-scale hydropower station in Yunnan Province during the "14th Five-Year Plan" period. The first unit of Toba Hydropower Station project, the fourth terraced power station in the "Fourteenth Five-Year Plan" development program, has successfully completed the 72-hour test run, marking the official commissioning of power generation in Yunnan Province, which is the only large-scale hydroelectric power station commissioned during the period of "Fourteenth Five-Year Plan". Toba Hydropower Station is an important part of China's national "West-East Electricity Transmission" backbone project, with a total installed capacity of 1.4 million kilowatts, the station is expected to be completed after the completion of the average annual power generation of about 6.23 billion kWh, equivalent to an annual savings of about 1.913 million tons of standard coal, reduce carbon dioxide emissions of about 5.223 million tons, with significant economic benefits and ecological and environmental benefits. economic and ecological benefits. The first unit of Toba Hydropower Station was put into operation" was reported by CCTV "News Broadcast".

Toba Hydropower Station is located in the territory of Zhonglu Township, Weixi County, Diqing Prefecture, Yunnan Province, belonging to the first-class large (1) type project, the water retaining building adopts crushed concrete gravity dam, with a crest elevation of 1740m, a total length of 477m, and a maximum dam height of 158m, which is the highest crushed concrete gravity dam under construction in China at present. Since the construction of the project, the dam construction team has made full use of the six systems of intelligent crushing, intelligent temperature control, intelligent grouting, intelligent materials, intelligent mixing, and universal application to realize the real-time monitoring of the whole process of concrete production, warehousing, crushing, and curing, etc., and has achieved an average rise of 14 meters in five consecutive months, and the maximum rise of 126 meters per year, which has set a new record of the rising speed of a crushed concrete dam, and has achieved a new record of the rising speed of a crushed concrete dam with a core sample of 26.5 meters in length. The core sample set a new world record for coring of a crushed concrete gravity dam, realizing high-quality power generation one year ahead of schedule, which is the fastest dam of the same type in the world. The company provided four HL240-2S3000L pre-cooled concrete mixing plants and a full set of ancillary facilities for the Toba Hydropower Station project, and was responsible for the production of all concrete for the dam pouring. The company adheres to the party building leadership, gives full play to the pioneering role of party members, actively responds to the owner's requirements for intelligent dam construction, and takes scientific and technological innovation as the core to develop an intelligent production control system for hydraulic concrete, which includes advanced intelligent technologies such as vehicle scheduling, automatic loading of raw materials, automatic temperature detection, detection of energy consumption in production, remote centralized control, intelligent operation and maintenance management, and intelligent production data management, etc., and provides the best quality concrete pouring service for the dam of the Toba Hydroelectric Power Station. This provides a reliable guarantee for the high quality of concrete pouring in Toba Hydropower Station. During the operation of the concrete system, the company has achieved a number of achievements, such as "the highest monthly strength of 230,000 cubic meters", "the highest daily output of 11,800 cubic meters", "the world's longest (26.5 meters) core sample of crushed concrete", and "the longest core sample of crushed concrete in the world". and "the world's longest (26.5 meters) core sample of crushed concrete" and many other construction records of crushed concrete. The hydraulic concrete intelligent production control system was also successfully selected in the "2024 Water Conservancy Advanced Practical Technology Key Promotion Guidance Catalog".
