In order to completing the full connection of two key water diversion inclined shafts, setting a new mechanised construction record in China\u2019s pumped storage power station sector, as well as successfully applying a new mechanised full-section excavation model for inclined shafts, the No. 2 diversion shaft on the Luoning Pumped Storage Power Station was broken through by China\u2019s first domestically produced large-diameter, large-inclination inclined shaft TBM.<\/p>\n
Being developed by CREC\u2019s subsidiary China Railway Engineering Equipment Group, State Grid Xinyuan Luoning Company, and Sinohydro Bureau 6, TBM Yongning completed the No. 2 shaft by excavating upwards at an angle of 38.742 degrees and bored 860m of the 873m length.<\/p>\n
The date of commencing the digging process by this TBM was April 25, whereas its advance was 22.75m per day and 332m per month, setting a record for inclined shaft TBM tunneling in China.<\/p>\n
TBM Yongning broke through on the No. 1 inclined diversion shaft in January this year.<\/p>\n
As the largest pumped storage power station under construction in central China, Luoning Pumped Storage Power Station in Henan province has a total installed capacity of 1.4 million kW. With the aim of creating a new approach for the construction of pumped storage power stations in China, this project involves optimising the upper inclined shaft, the middle adit and the lower inclined shaft into a primary inclined shaft.<\/p>\n","protected":false},"excerpt":{"rendered":"
