Description

TECHNICAL FIELD

[0002] Perforated pipe is a kind of pipe material with multiple holes on the surface, commonly used in drainage, irrigation, filtration and ventilation applications. According to the different materials and designs, perforated pipes can be adapted to a variety of purposes and environments. In the underground drainage system, water can be collected through the holes on the surface of the perforated pipe and guided to the main drainage pipeline.

[0003] There are many types of perforated pipes on the market at present, such as a perforated pipe for rainwater collection disclosed on China Patent Network with publication number CN205062986U. This perforated pipe can be used in drainage systems, but there are some defects and deficiencies to be improved: (1) Some existing perforated pipes are difficult to control the release rate when used in drainage systems due to structural design reasons, which can easily lead to excessive instantaneous release of fluid, resulting in the perforated pipe unable to operate stably for a long time and requiring higher subsequent maintenance; (2) The surface holes of some existing perforated pipes are easily blocked by silt impurities, corrosion products or scale under long-term use or in poor environments, so that the fluid cannot pass smoothly, resulting in low efficiency or even failure of the drainage system; (3) The perforated pipe often needs to be butt jointed according to the length requirement of the pipeline system when in use, but some existing perforated pipes lack effective positioning and guiding structures, making it inconvenient to butt joint the perforated pipes and difficult to quickly complete the butt joint, thereby reducing the efficiency of butt joint work.
