A method for analyzing the distribution of groundwater infiltration and pipeline sewage infiltration in underground pipe networks

Abstract

The invention relates to a method for analyzing underground pipe network underground water penetration and pipeline sewage seepage distribution. The method includes the following steps that S1, pipelines are grouped, pipeline liquid level meters and underground water level monitoring instruments are installed; S2, inspection well water level data and underground water level data are screened; S3,the difference between an inspection well in each group of pipelines and underground water is calculated; S4, the instantaneous flow under each differential pressure is calculated; S5, time and the instantaneous flow are subjected to integration through an integral formula, and the penetration amount or the seepage amount in a specific time period is calculated; S6, according to the relation between the water level difference and the flow, distribution of the underground water penetration capacity and the pipeline sewage seepage capacity of a sewage pipeline system in a period of time can be obtained respectively. The liquid level meters are arranged in the inspection wells, the underground water level monitoring data is integrated, the water level data is collected for a long time, the penetration and seepage of the pipelines in the operation process are evaluated, support is provided for optimal scheduling, and the maintenance work is guided.

Description

technical field [0001] The invention relates to the urban underground drainage pipe network technology, in particular to a method for analyzing the distribution of underground water infiltration and pipe sewage seepage in the underground pipe network. Background technique [0002] At present, the sewage collection efficiency of the urban drainage pipeline system is low, and the groundwater pollution is serious. There are phenomena such as groundwater infiltration into drainage pipes and sewage seepage from drainage pipes to pollute groundwater. When groundwater infiltrates into sewage pipes, due to the dilution of groundwater on sewage, the concentration of sewage in sewage treatment plants will decrease, and nitrogen may increase, which will impact the operation and treatment effect of sewage treatment plants; The reason is that the buried time is long, and the anticorrosion quality of pipelines and other facilities in the past was poor. The sewage pipelines in many cities...
