Recently, Hangzhou Jianghe Electromechanical Equipment Engineering Co., Ltd. received a thank-you letter from the Baihetan Construction Bureau of China Water Resources and Hydropower Fourth Engineering Bureau Co., Ltd., the construction party of the Baihetan Hydropower Station dam.

 

Hangzhou Jianghe Mechanical and Electrical Equipment Engineering Co., Ltd. provided 4 sets of HL400-4F5000L concrete mixing building for Baihetan Hydropower Station dam concrete production system, the dam concrete production system is divided into high line concrete system and low line concrete system, respectively, set up 2 sets of 4X5 mixing building, the high line concrete production system is laid out on the gently sloping ground of the left bank at the elevation of 834m at the shoulder of the dam, and the low line concrete production system utilizes the terrain formed by the excavation of the left bank inlet platform at the elevation of 738m to be laid out. system is arranged by utilizing the terrain formed by excavation of the left bank inlet platform at 738m elevation. The low-line system started to be installed in August 2016, completed installation and commissioning and trial production on March 15, 2017, and was dismantled in October 2020 after 1,286 days of stable operation; the high-line system started to be installed in October 2016, completed installation and commissioning and trial production on April 30, 2017. From the start of the first concrete production on April 12, 2017 to the completion of the last concrete pouring of the dam on May 31, 2021, which lasted nearly 50 months, the dam concrete production system produced a total of more than 8.1 million m3 of concrete, creating a world record of 273,000 cubic meters of monthly production and 2.7 million cubic meters of annual production of concrete for the same type of concrete production system.

 
The building realizes the localization of the whole set of equipments and is equipped with JF5000 high pivot point self-falling concrete mixer with independent intellectual property rights, which has the advantages of high mixing efficiency and good mixing quality, and can completely replace the imported host machine. The building optimizes the air-cooling and ice-adding devices to guarantee the production of temperature-controlled concrete; optimizes the dust removal system and improves the working environment; sets up several data interfaces to realize seamless data link with the automatic vehicle identification, dispatching and digital dam system to improve the level of intelligence and production efficiency. With multiple data interfaces to realize seamless data linkage with automatic vehicle identification and digital dam system to improve the level of intelligence and production efficiency, it is currently the world's largest self-falling pre-cooled concrete mixing plant, which can produce high-quality temperature-controlled concrete, laying a solid foundation for the construction of the "Seamless Dam", a 300-meter-class extra-high arch dam at Baihetan Hydropower Station.

 

Hangzhou Jianghe Mechanical and Electrical Equipment Engineering Co., Ltd. will bear in mind the General Secretary's instructions, follow the footsteps of the motherland's construction, adhere to the innovation lead, and help more major national projects.
