RESEARCH ON CONSTRUCTION TECHNOLOGY OF TWO-STAGE ULTRA-DEEP SHAFT IN STORAGE POWER STATION
The research on two-stage ultra-deep shaft construction technology of storage power station involves the key technology of efficient and safe construction under complex geological conditions.The research focuses on optimization of excavation method,construction of safety support system,accurate control of pilot hole and improvement of safety guarantee measures.Taking Yangjiang pumped storage power Station as an example,rapid excavation and stable support of shaft are realized by using advanced drilling and blasting technology and supporting materials.At the same time,the directional deviation correction and inclination measurement technology is used to ensure the accurate construction of the pilot hole and optimize the construction process of shaft expansion.This study provides technical support and safety guarantee for the construction of ultra-deep shaft of storage power station,and promotes the smooth construction of the project.
