Abstract
In response to the challenges of Yong'an Tunnel under the water resource allocation project in western Chongqing,such as poor stability of the surrounding rock and high safety risks of drilling and blasting methods,this paper systematically introduces the full process practice of using cantilever tunneling machines in the construction of small section tunnels,including equipment selection,operation procedures,cutting methods,tunnel dust reduction,and slag removal methods.The application results show that the equipment has minimal disturbance to the cofferdam and excellent forming quality,with a monthly footage of over 150m in soft rock sections,verifying its applicability in the construction of small section tunnels near sensitive buildings.关键词
