Research on Comprehensive Benefits of Excavation Construction Technology of Inclined Shaft of Pressure Pipeline
In view of the characteristics of excavation of an inclined shaft of a pressure pipe in a pumped storage power station,such as large cross-section diameter,large depth,and complex geological conditions,two methods of tank climbing and raise drilling rig were proposed to excavate the inclined shaft.After comparative analysis of the construction techniques of the two plans,the production costs of tank climbing and raise drilling rig inclined shaft construction were calculated,and the comprehensive benefits of the two construction plans were analyzed from three aspects:economic,environmental protection,and safety benefits.The analysis results show that the climbing tank has certain advantages in terms of economic benefits,but the raise drilling rig has significant advantages in environmental benefits and safety benefits.It has broad application prospects and promotion value in the field of hydropower engineering construction.
