混凝土缓降装置在抽水蓄能电站斜井衬砌中的应用OA

A high-head pumped storage power station is equipped with four long steeply-inclined shafts in its water conveyance system,which are lined with steel pipes.In accordance with the engineering structure and actual site conditions,the paper develops a brand-new charging and distribution device for inclined shaft concrete mixture.The targeted optimization and improvement are conducted on the device in response to problems arising during construction,and the achieved achievements can provide valuable technical references for concrete construction of similar inclined shaft projects.
