The culvert is a drainage structure commonly existing in cities, is a difficult area for the discharge and treatment of polluted water quality such as domestic sewage, rainwater, industrial sewage and the like, is also environmental treatment, and is an important point and a difficult point for the water quality improvement and the urban water supply and drainage treatment quality improvement. The prior culvert mainly has the problems of great difficulty in drainage investigation, influence of sewage on the downstream water system quality and other environmental aspects. To improve these situations, new technical routes and better engineering results are needed. The water quality of the dark culvert in China is obviously optimistic, and the poor and extremely poor water quality is more. At present, the quality improvement and efficiency improvement of the culvert water quality have great progress, and great economic benefit and environmental benefit can be obtained in the aspect of the transformation of the culvert water quality after the quality improvement and efficiency improvement.
The implication is formed after the urban river space is continuously immersed and extruded along with the aggravation of the urban process and the river is covered. When raining, a large amount of pollution is flushed into a river course, the long-term treatment of the river can not be ensured, and once the underground culvert is leaked and broken or collapsed, the upper building is easily caused to be settled and inclined or even collapsed, so that serious safety accidents are caused. The sealing of the adult months causes accumulation of black mud and harmful gases, such as biogas generated by decomposition of organic matters, and the treatment work difficulty is extremely high. The related investigation finds that the hidden remediation is extremely difficult in terms of source tracing of the discharge, coordination of the perforating operation and black clearing of the remediation, and serious potential safety hazards exist in a narrow and moist construction environment.
However, the implication is an essential component of urban operation, just like the human large intestine. Gastrointestinal obstruction, and people need to get out of the disease; the meaning is not clear, the light people destroy the environment, and the urban appearance is influenced; serious people cause safety accidents and cause life and property loss.
The city needs the inclusion, but is also not separated from the inclusion, so that the actual working condition of the inclusion, namely the water ecology of the inclusion, such as the water flow rate, the sludge content, the methane content above the inclusion, and the like, is very important for ensuring the normal operation of the city. However, because the position of the culvert is often not observed in the field, and each city has a plurality of culverts, namely, the city can be observed in the field and a large amount of manpower and material resources are needed, the culvert simulation system is built, simulation data of the culvert are obtained by observing the culvert simulation system in real time, and corresponding maintenance measures are taken for the culvert according to the obtained simulation data, so that the culvert can provide normal service for the city, and the city is enabled to run normally, thereby having great economic significance and social value.
