Problems solved by technology
[0005] This monitoring method can only be used for pressure monitoring of some main pipelines, and cannot effectively monitor all pipelines in the entire pipeline network.
Liquid level gauge monitoring based on scattered points can only identify the pressure situation of the pipe section at the monitoring point, but lacks a comprehensive grasp of the pressure situation of the overall pipe network system, resulting in the inability to take timely countermeasures when accidents occur in some areas

The invention provides an under-pressure monitoring method of a municipal sewage pipe network in cities. The method comprises the following steps: building a municipal sewage pipe network diagram; marking the sewage discharge amounts of different areas on the municipal sewage pipe network diagram so as to acquire a sewage load spatial distribution map; selecting monitoring points according to the marked municipal sewage pipe network diagram; identifying discharge process morphological parameters of the typical residential areas according to flow monitoring data at water discharge monitoring points of typical residential areas; establishing municipal sewage pipe network fluid dynamics models and identifying the parameters of the municipal sewage pipe network fluid dynamics models; acquiring total length and spatial distribution of municipal sewage pipe network under-pressure pipelines according to the established pipe network fluid dynamic models and the identified parameters. According to the scheme, as the total length and spatial distribution of the municipal sewage pipe network under-pressure pipelines are acquired through the established network fluid dynamics models, the monitoring effects on the states and the positions of the under-pressure pipelines are improved.
Description
Technical field [0001] The present invention relates to the technical field of municipal administration, in particular to design a method for monitoring under pressure of urban municipal sewage pipe network. Background technique [0002] With the development of cities and the increase in population, the urban sewage pipe network has become more overwhelmed. Therefore, the monitoring of urban sewage pipe networks is increasingly important. [0003] The existing municipal sewage pipeline network live pressure monitoring program mainly installs monitoring equipment such as level gauges in some inspection wells of the main network to monitor the liquid level of the well, and then according to the buried depth and diameter of the pipeline connected to the inspection well To determine if the pipeline is blocked or overflowing. [0004] There are a large number of municipal sewage pipe networks in cities, and it is obviously not economically feasible to install monitoring equipment on eac...
