Study on the Key Techniques and Safeguards of the Municipal Water Supply Pipes Constructions in Rocks along the Upper Reaches of Yangtze River
Taking Yuelai Waterworks with the daily water supply capacity 600,000 tons in Chongqing as an example,this study focuses on the characteristics and difficulties of municipal water intake constructions in rock along the upper reaches of Yangtze River.The key techniques of blasting engineering with the large diameter (2×14000mm),large geological depth (50m) of water pipeline constructions are described.The result shows that the smooth blasting technology can be applied to control the blasting contour precisely,the best blasting effect can be achieved through optimizing the blasting parameters,and the field precise leveling monitoring and information feedback can be successfully applied to guarantee the project quality and safety.Meanwhile,this demonstration project provides valuable experience and technical guidance for the future large diameter,large geological depth of water pipeline construction in rock.
