Technical Field

[0001] The utility model relates to the field of drainage pipes, in particular to a drainage pipe device used in municipal engineering. Background Art

[0002] Drainage pipe installations in municipal engineering are a vital part of urban infrastructure. They ensure effective drainage and sewage treatment in and around the city. These pipe systems require not only reasonable design and precise construction, but also environmental protection and long-term operational reliability. Drainage pipe installations in municipal engineering are not just a kind of infrastructure, they are an important guarantee for urban development and the quality of life of residents.

[0003] The existing technology has the following deficiencies: many areas are affected by the monsoon and have distinct dry seasons and rainy seasons. In the rainy season, precipitation increases significantly, which may cause waterlogging; in the dry season, precipitation is scarce and the drainage demand is greatly reduced. Since the inner diameter of the existing municipal drainage pipes is fixed, it is difficult to flexibly carry out drainage work in areas with a large precipitation span. When the precipitation is too high, the drainage system cannot quickly discharge a large amount of rainwater, which may cause water accumulation in low-lying areas such as roads and basements, and even cause floods. This situation will seriously affect the lives and transportation of citizens and may also cause property losses; when the precipitation is too low, the drainage pipes may be difficult to clean due to insufficient flow, causing accumulation of substances in the pipes, such as sediments or debris, which gradually lead to pipe blockage.

[0004] Therefore, it is necessary to invent a drainage pipe device for municipal engineering. Utility Model Content
