The cause of poor drainage is due to blockages in the underground drainage pipes and root obstructions. In particular, common drainage pipes are prone to clogging from gravel, tree roots, and debris, and when there are blockages or root obstructions in buried pipes, it becomes difficult to address them, leading to the hassle of replacement. Mitsuba Drain is a drainage pipe with slotted inlets that has excellent water collection capabilities. The direction of drainage aligns with the direction of the inlets, allowing water to flow in smoothly with outstanding collection ability. It is effective for ground, parks, construction site drainage works, and other groundwater measures. 【Features】 ■ Outstanding water collection capability ■ Good drainage and durability ■ No movement of fine soil ■ High resistance to water scale adhesion ■ Sufficient pressure resistance *For details on the mechanism and construction examples, please download the PDF.

An "ankyu" refers to a waterway buried underground, and the method of improving drainage by flowing and draining infiltrated water from the surface into it is called "ankyu drainage." Historically, ankyu drainage using bamboo and sod bundles has been practiced, but currently, resin materials are mainstream, and various shapes of ankyu drainage pipes are available on the market. Our "Mitsuba Drain" is chosen by many companies and municipalities due to its high performance and ease of installation. [Shape Comparison (Partial)] ■ Mitsuba Drain - Multi-drainage channel in one cross-section - Honeycomb structure ■ Perforated Pipe - Single drainage channel in one cross-section - Circular pipe with small holes scattered throughout *For more details, please refer to the related links or feel free to contact us.

The "Mitsuba Drain" is a drainage pipe with a structure suitable for circulating water and air in the soil. By making the collection openings continuous slits (linear) and increasing the collection area, it achieves overwhelming collection and drainage performance. It is less likely to become clogged with deposits such as water stains, and even if one drainage route is blocked, water can be diverted to other drainage routes. Additionally, when buried under railway tracks as a countermeasure against mud eruptions, it has excellent pressure resistance to withstand the repeated loads of trains. 【Features】 ■ Overwhelming collection and drainage performance ■ Does not clog ■ Resistant to root intrusion ■ Excellent pressure resistance ■ Suitable for improving soil environment *For more details, please refer to the related link page or feel free to contact us.
