The "DK Drain Pipe" is a new type of driven drainage pipe made of stainless steel, designed to be driven into the ground with threaded ends (male and female threads) to drain water from the ground, lower the groundwater level, and prevent slope collapse. 【Features】 ■ Improved durability and cost-effectiveness - By using stainless steel for the pipe material, it is resistant to rust, which can reduce lifecycle costs. ■ Improved workability - The pipe can be driven directly without prior drilling. - By striking the tip bit attached to the end of the pipe, the impact force is directly transmitted, making it easier to drive in. - The threaded ends of the pipe allow for easy connection between pipes. ● Please download the catalog for the construction procedure.

The high-durability STK net is a rust-free polyester hexagonal net that serves as an alternative to metal wire. Originally developed as a net for marine aquaculture, it has been repurposed for land applications and is used for various purposes such as rockfall prevention, sediment control, wildlife damage prevention, and fall prevention. It is ideal for areas along the coast where salt damage is a concern, volcanic regions with acidic gas emissions, and cultural properties or scenic areas where aesthetics are important. It contributes to improved weight and workability, being about one-fifth the weight of traditional metal wire.

【Overview】 - It suppresses the erosion and runoff of surface soil on slopes using a polyester net and vegetation mat. 【Features】 - The specification materials are lightweight, making it possible to transport and deliver to relatively difficult sites such as narrow places and hillside works. - The use of a flexible net allows for close installation on uneven slopes. - By using a vegetation mat in conjunction, greening can be achieved.

Mikune District, Sayō Town, Sayō County, Hyōgo Prefecture ◆ Damage from Typhoon No. 23 in 2004 In response to the damage caused by Typhoon No. 23 in 2004, "unit nets" were adopted at planned locations for the restoration of windfall trees and slope collapses, and construction was sequentially ordered based on the plan. ◆ Damage from Typhoon No. 9 in 2009 While construction was progressing sequentially for restoration measures, we were hit by damage from Typhoon No. 9 in 2009. Slope collapses occurred in surrounding areas, centered around the restoration plan area. Although there were still unaddressed areas within the restoration plan that experienced slope collapses, the adjacent area where "unit nets" had been installed was able to prevent collapses. There were houses below the slopes, but thanks to the installation of "unit nets," safety was successfully maintained. ● For more details, please download the materials.

【Features】 ○ An environmentally friendly ground reinforcement method that allows for forest protection, landscape preservation, and greening of slopes. 〇 It can be constructed even in narrow sites such as residential areas by using lightweight materials. ○ Compared to conventional methods using retaining walls and rebar insertion, it can reduce costs and shorten construction periods. 〇 Applicable in cut slopes and landslide-prone areas when used in conjunction with slope protection works such as wire mesh and vegetation mats. 〇 Proven track record of lifting special alert zones for sediment disasters (red zones). ○ Registered with the Ministry of Land, Infrastructure, Transport and Tourism NETIS under registration number KK-010068-V (published until April 2017). * For slopes with spring water, it is effective to combine with drainage work using "DK Drain Pipes." * We also have a collection of case studies from various fields, so please download from the catalog below!
