Abstract

The construction of working shafts in shield tunneling projects is a challenging endeavor marked by deep excavation and intricate operations. It is further compounded by the frequent occurrence of water inrush accidents, particularly in regions where karst development is prevalent in the surrounding environment. These safety accidents during the construction of working shafts can have a cascading impact. They jeopardize the well-being of construction workers, pose threats to the lives and property of nearby residents, and disrupt the overall construction progress of the tunnel project. This paper is dedicated to a comprehensive analysis of the emergency response and monitoring strategies that come into play following a water inrush accident within a working shaft, with a specific emphasis on the context of constructing leading conduits in areas characterized by karst development. The specific content includes a technical analysis of the accident causes combined with geology and hydrology and the surrounding environment, and then formulating accident remedial measures and strengthening the monitoring of the surrounding environment in the whole process of emergency rescue, etc., and the monitoring results show that the risk of further expansion of the danger can be effectively solved by taking measures such as installing valves and drainage and grouting construction at the water inrush hole.
