China is a country in a mountainous region, and with the continuous development of traffic networks, the construction of high-quality tunnels has become a development trend. Tunnel groundwater is a problem that has plagued engineering builders during their construction and operation. When the tunnel is built, underground water flows out along with the excavation of the tunnel space, and the waste of underground water resources is caused. In the traditional engineering design and construction, the development and utilization of water resources are not emphasized. According to the research: some tunnels are positioned in a geological section rich in underground water, a large amount of water inrush phenomenon can occur during construction, the measured water inrush amount of the underground water can reach tens of thousands of cubes per day, the water inrush amount of the tunnels can reach hundreds of thousands of cubes, and the water pressure reaches 2MPa or more; particularly, in the tunnel of the karst area, a karst pipeline is communicated with the ground surface, and a crack-karst cave (a river) exists locally. After a heavy storm, the tunnel water inflow may reach hundreds of thousands of cubes. For the built tunnel, a large amount of sewage flows out due to the action of underground rivers, karst water, atmospheric rainfall and groundwater runoff, so that water resource waste is caused.

And aiming at the problem that underground water is gushed after the tunnel is excavated, relevant research data are consulted, and reports on the aspect of generating electricity by using the underground water in the tunnel are not found. To this, when guaranteeing tunnel structure safe operation, carry out make full use of tunnel groundwater resource, avoid the water waste. The underground water in the geological section enriched with the tunnel underground water is used for generating power, ventilating and lighting in the tunnel and other equipment to operate. The method solves the problems of efficient utilization of tunnel underground water resources and environmental protection, breaks through the technical bottleneck, creates an intelligent tunnel and intelligent power generation, and accords with the scientific and technological innovation and energy-saving and environment-friendly concept provided by the state.
