The Importance Of Groundwater Pipeline Inspection

The development of the city is inseparable from the construction of underground water pipelines. Various underground water pipelines for industry, sewage, life, etc. are laid in the city's underground pipeline network, which is closely related to urban life. Therefore, it is necessary for us to do a good job in the inspection of underground water pipelines and to maintain the construction of underground water pipelines.

The common groundwater pipeline problems in the past generally fall into these categories:

In the first category, due to various structural defects and imperfect drainage outlets, a large amount of external water such as groundwater penetrates into the pipeline, and the water contained in the water body is poured into the pipeline, resulting in "no pollution".

The second category is that there is no separation of sewage discharge from rainwater, which results in sewage in rainwater pipes and rainwater in sewage pipes.

The third category, pipeline maintenance is lagging. In addition to not being able to discover its existing or potential problems and defects in time, it will also cause the river and storage water to be polluted by the silt in the pipeline entering the river on rainy days due to unscheduled dredging. Due to the problems of groundwater infiltration, rain-sewage mixing, and river water backfilling, the rainwater pumping station and confluence pumping station cannot operate normally according to the designed water level. The result of high water level operation is that the result of emptying before rain is "one chamber of black water" Into the river.

The fourth category is the drainage pipelines laid above the groundwater level. The aging and rupture of the pipelines causes the outflow of sewage to become the main factor polluting groundwater and soil.

Fifth type, a large amount of groundwater flows into the pipeline through the leaking interface, and the sediment flows out, causing the surrounding of the pipeline to be hollowed out. The foundation bearing capacity of the pipeline declines, there is a disconnection and misalignment, and even the pavement void occurs. Sagging or sudden collapse.

Due to the above problems, the inspection of urban groundwater pipelines is particularly important. If the groundwater pipeline problem is not dealt with in time, can you imagine a series of problems happening? Due to continuous flooding in cities, rainfall, ecological destruction of rivers, and poor quality of domestic water, underground water pipeline testing cannot be ignored.
