Abstract: With the continuous increase and in-depth development of large-scale hydropower projects in my country, the scale of penstock projects in the water diversion and power generation system is increasing. The traditional penstock construction technology has many limitations and cannot meet the development needs of large-scale hydropower projects. The construction of the penstock hole and the installation of new technologies aim to complete the construction of the penstock quickly, safely and with high quality, adapt to the requirements of safety, environmental protection, and health, reduce the number of labor, and reduce labor intensity, thereby improving the controllability of the construction period, the quality of the project, and the Safety and environmental protection.
