Research and Application of Key Technologies for Ultra High Pressure Grouting of Yangjiang Pumped Storage Power Station in Guangdong Province

Abstract

Abstract The most effective guarantee measure for the permeability stability of reinforced concrete lined high-pressure waterways is grouting. The traditional grouting treatment techniques and specifications can not effectively adapt to construction projects with higher requirements. This paper comprehensively expounds the new theoretical research system and grouting engineering design method proposed through model test and inverse calculation, and introduces the construction technology and technical requirements of 10Mpa ultra-high pressure grouting in the engineering field in combination with the construction practice of Yangjiang Pumped Storage Power Station, so as to provide useful reference for the construction of high-pressure waterway of pumped storage power station project.
