Description

Technical Field

[0001] The utility model relates to the technical field of inspection wells, in particular to a non-standard inspection well for non-water-stopping transformation of a large-diameter drainage pipeline. Background Art

[0002] The main function of a sewage treatment plant is to remove harmful substances from urban domestic sewage in order to purify the water quality. If a sewage treatment plant stops operating, untreated sewage will be directly discharged into natural water bodies such as rivers, lakes and seas, polluting the water bodies, further destroying the ecological balance and endangering environmental health.

[0003] At present, most of my country's urban sewage treatment plants implement the Class A discharge standard in GB 18918-2002. In order to further improve the water environment quality and meet the development needs of sewage resource utilization, Beijing, Tianjin, Anhui, Jiangsu, Shaanxi and other places have successively issued more stringent basin or regional discharge standards in recent years. In the process of upgrading and transforming sewage treatment plants, it is necessary to transform the original drainage pipes. With the strict requirements of environmental protection policies, the ecological environment authorities will not approve the long-term shutdown of sewage treatment plants and the direct discharge of untreated sewage, which requires the upgrading and transformation to adopt non-stop water construction measures.

[0004] When renovating the existing large-diameter drainage pipe, it is necessary to connect it to the newly built drainage pipe. Therefore, an inspection well needs to be added at the connection between the existing large-diameter underground drainage pipe and the newly built drainage pipe, so as to divert all the fluid media running in the existing drainage pipe to the newly built pipe. The old and new pipes are buried deeper and have larger diameters, so their inspection wells are also deeper and larger in size. The construction of non-standard inspection well structures takes a long time and must ensure that the large-diameter underground reinforced concrete water supply and drainage pipes operate normally and safely without water cuts during the relocation, which is a difficult problem in the industry.

[0005] To this end, the utility model proposes a non-standard inspection well for non-stop water conversion of large-diameter drainage pipes to solve the overflow pollution problem caused by water and production suspension of sewage treatment plants when large-diameter drainage pipes are converted. Utility Model Content
