[0002] my country's highway and railway construction is in a stage of rapid development. There are more and more mountain tunnels to be built and in operation. The exhaust gas and dust raised by vehicles during driving will adhere to the tunnel wall, which is harmful to the tunnel. Its own structure and the passage of vehicles have caused great safety hazards
At present, the cleaning methods for tunnel walls mainly include manual cleaning and tunnel cleaning vehicles, which have low cleaning efficiency, waste manpower and material resources, and cause traffic jams during the cleaning process, with low economic and environmental benefits.

The invention belongs to the technical field of tunnel engineering and provides a water-saving system and method for cleaning a tunnel wall through earth surface rainwater. The water-saving system forcleaning the tunnel wall through the earth surface rainwater comprises a rainwater collecting system, a rainwater pumping system and a rainwater guiding pipe. The rainwater pumping system is arrangedat a drainage ditch inside a tunnel, and connected to a rainwater collecting device through the rainwater guiding pipe to feed back rainwater in the drainage ditch of the tunnel to the rainwater collecting device, and the rainwater is recycled through purification and storage. According to the method for cleaning the tunnel wall by intelligently and circularly adopting the rainwater resource, therainwater resource is sufficiently utilized, manpower and material resources are saved, environmental friendliness is achieved, the adaptability is high, traffic congestion brought by a traditional method is reduced, and the economical and environmental benefits of the system and the method are remarkably enhanced.
Description
technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to a water-saving method for cleaning tunnel walls with surface rainwater. Background technique [0002] my country's highway and railway construction is in a stage of rapid development. There are more and more mountain tunnels to be built and in operation. The exhaust gas and dust raised by vehicles during driving will adhere to the tunnel wall, which is harmful to the tunnel. Its own structure and the passage of vehicles have caused great safety hazards. At present, the cleaning methods for tunnel walls mainly include manual cleaning and tunnel cleaning vehicles, which have low cleaning efficiency, waste manpower and material resources, and cause traffic jams during the cleaning process, with low economic and environmental benefits. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent m...
