Description

Technical Field

[0001] This invention relates to the field of drainage pipe well connections, and more particularly to an adjustable snap-fit ​​pipe well connection component. Background Technology

[0002] Drainage pipes are mainly responsible for draining rainwater, sewage, and agricultural irrigation. Drainage pipes are divided into plastic drainage pipes, concrete pipes, and reinforced concrete pipes.

[0003] Well connection currently includes the following technologies: concrete pipe mortar caulking and HDPE pipe interlayer construction.

[0004] Mortar caulking of concrete pipes: using mortar to manually caulk the gaps in pipes and manholes.

[0005] HDPE pipe intermediate layer construction: First, clean the pipe surface with a brush or cotton yarn, then evenly apply a layer of adhesive, followed by sprinkling a layer of dry coarse sand (0.5-2.0mm particle size) on top. After curing for 10-20 minutes, a rough annular intermediate layer will form on the outer wall of the pipe. Then, use mortar to insert into the pre-reserved opening in the inspection well for connection.

[0006] The following are the disadvantages of using mortar to seal concrete pipes: the quality of concrete pipe well connections is poor when using mortar to seal them, and the connection of the pipe wells may not be tight during the construction process.

[0007] The intermediate layer method for HDPE pipes has the following disadvantages: the connection point is a reserved opening for inspection wells, the processing space is small, and the connection effect is not good when using mortar to seal it.
