Urban drainage network online detection method

Abstract

The invention discloses an urban drainage network online detection method. The method includes the steps that S1, an on-site monitoring system of a drainage network is built, and pipeline liquid level parameters and pipeline displacement parameters of all monitoring points in the operation process of the drainage network are collected and stored in a pre-warning database; S2, according to the pipeline position, the elevation, the pipeline diameter, the gradient and pipeline roughness coefficient parameters of each monitoring point, a static database of the drainage network is built, and the static database is associated with the pre-warning database; S3, a state analysis system of the drainage network is built to obtain the operation state of the drainage network; and S4, a pre-warning system of the drainage network is built, pipeline disease problems in the operation process of the drainage network are judged in real time according to the state of the drainage network and pipeline displacement state analysis results, and real-time pre-warning is achieved. A whole set of monitoring method is disclosed for stable and safe operation of an urban drainage network to achieve informatization management of the urban drainage network, and bases are provided for urban drainage network planning and construction.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering information and relates to an online detection method for urban drainage pipe networks. Background technique [0002] The urban drainage pipe network system refers to the system composed of pipes and channels for collecting and discharging sewage, waste water and rainwater and their ancillary facilities. Urban drainage pipe network is an important part of urban infrastructure and the material basis for the survival and development of cities. In recent years, with the continuous improvement of my country's urbanization process, the investment in urban infrastructure has also increased year by year, and the construction of urban drainage pipe networks has developed rapidly. At the same time, urban waterlogging, pipeline congestion, pipeline settlement, Sewage illegal discharge and other disease problems have also become increasingly prominent, becoming an important issue that threatens...

Problems solved by technology

[0008] Although the traditional detection method is flexible and simple, it is more detailed and accurate for the detection of a specific section of pipeline, but it is time-consuming and laborious, and requires a high level of experience for the testing personnel, and it is impossible to give early warning of pipeline diseases in time, and it is no longer suitable for modern drainage network management.
