Research on the Selection Technology of Long-distance Pipe Jacking Machine for Superhard Rock
With the rapid development of water conservancy engineering construction in China,underground tunnels in water conservancy engineering are increasingly using pipe jacking construction technology due to their long routes,high rock strength,and other objective factors.Due to the long route and complex geological conditions,the selection of pipe jacking machines is particularly important before construction.Based on the optimization project of Hanjiang,Rongjiang,and Lianjiang water systems connection,this paper designs the cutterhead,main drive,main hydraulic cylinder,and relay room of the pipe jacking machine for long-distance pipe jacking construction in ultra hard rocks,and summarizes the selection techniques.
