in the construction of shaft 1, 637 m, of the water diversion system of songyang pumped storage power station, the "tiangong no" shaft tunneling machine shone brilliantly and set a new industry record many times with brilliant construction results! Its daily maximum footage reached 20.18 meters and its monthly maximum footage exceeded 236.96 meters, successfully solving the difficult problem of hard rock excavation in ultra-deep shafts.
"Tiangong" shaft boring machine is a 700-meter ultra-deep shaft intelligent high-end equipment tailored for the extreme working conditions of Songyang Pumped Storage Power Station. The whole machine weighs 482.5 tons, is 37.7 meters high, and has an excavation diameter ranging from 6.97 to 9.97 meters. It integrates intelligent guidance and deviation correction, tunneling, shotcrete and anchor support, automatic fire alarm and fire extinguishing functions, thus truly realizing the construction goal of "high precision, intelligence and unmanned" for ultra-deep shafts.
The "Tiangong" shaft boring machine is equipped with a self-developed digital twin platform as a "smart brain", deep integration of excavation, row, anchor, spray the whole process chain, to achieve the whole process of independent decision-making and precise coordination. Equipped with hundreds of high-precision sensors, relying on 5G communication real-time data back to the intelligent control screen, to achieve panoramic online monitoring of the underground environment, equipment operation and personnel status. Further improve process matching, construction accuracy and operation efficiency, and ensure the safety, quality and progress of ultra-deep shaft construction from the source.
build a strong city under the ground with the body of intelligence; With the ambition of low carbon, expand the new environment of energy sources. Zhejiang Songyang Pumped Storage Power Station is a key project of the national "14th Five-Year Plan" energy plan, with a total installed capacity of 1.4 million kilowatts and an annual power generation of 1.4 billion kilowatt-hours. It undertakes important functions such as power generation and water resources allocation. The successful application of the "Tiangong" shaft boring machine has made a great contribution to the construction of the new power system.
