Analysis on the Construction Technology of Excavating the Slag Guide Shaft in a Deep Shaft of a Diversion Tunnel

This article takes the construction of the slag guide well as an example to analyze its feasibility and the role of the slag guide well. The slag guide well is designed according to the sequence of the construction of the water tunnel and the shaft. Through the reasonable blasting radius and explosive quantity, it is formed by onetime blasting, andthrough the one-time blasting technology of the 5 m section of the bottom of the slag guide shaft and the shaft, it has successfully solved the suspended construction at the bottom of the shaft, ensuring construction safety and construction progress, and greatly reducing Construction cost.
