Description

Technical Field

[0001] The present application relates to the field of drainage systems, and in particular to a tunnel different-diameter overflow-stopping and crystallization-proof drainage blind pipe connection structure. Background Art

[0002] Drainage blind pipe is a pipe system used for drainage, also known as blind ditch or seepage drain pipe. It is mainly made of highly permeable pipes and is usually buried underground to collect and discharge groundwater or rainwater.

[0003] In construction projects, drainage blind pipes are widely used in drainage systems in basements, tunnels, roads, etc. They can effectively introduce groundwater or rainwater into water collection wells or drainage networks, thereby ensuring the dryness and safety of building structures.

[0004] At present, the connection structure between adjacent drainage blind pipes adopts a separate connecting pipe. During installation, the end of the drainage blind pipe close to the connecting pipe is inserted into the connecting pipe to complete the connection, thereby draining.

[0005] However, in the actual drainage process, due to the certain height difference between the connecting pipe and the drainage blind pipe, it is easy to cause obstruction to the liquid flowing through the connecting pipe; and liquid will easily accumulate in the connecting pipe. As time goes by, crystals will appear on the inner wall of the connecting pipe, and as the crystals continue to accumulate, it will eventually affect the smoothness of the liquid flowing through the connecting pipe, and even cause blockage.
