The "Corrugated RF Flume" is used in the construction project that directs the flow of the water from the upstream section of the Mizumigawa, a tributary of the Asuwa River, to the Asuwa River Dam through water replacement. Due to the wave-shaped components aligned in the flow direction, there is less flow resistance, allowing for an effective conveyance of the required water volume with a compact cross-section. Since it also supports buyback after use, it promotes a project approach that minimizes waste of materials. 【Project Overview】 ■ Client: Kinki Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism ■ Project Name: Asuwa River Dam Mizumigawa Sediment Retention Dam Construction ■ Contractor: Maeda Corporation ■ Product Name: Corrugated RF Flume *For more details, please download the PDF or feel free to contact us.

The "Corrugated RF Flume" has been adopted as a temporary waterway for the dredging work at the bottom of the dam lake.

We would like to introduce a case where the revolutionary fastening component "Elbolt" was adopted for the assembly of liner plates in the shaft of a water supply construction project in Matsumoto City, Nagano Prefecture. Liner plates are utilized in various civil engineering works as materials that are easy to assemble and disassemble, but the process of sandwiching the connection parts with bolts and nuts is cumbersome. "Elbolt" has streamlined this process, making the work more efficient. The design allows for fastening simply by passing through from one side of the hole, making it easy to handle. There is no need to hold the bolt in place on the opposite side, as it can be easily fastened by simply turning the nut side, allowing for very efficient inspections. 【Construction Overview】 ■ Client: Matsumoto City ■ Project Name: FY2023 Second Water Supply Main (Section 4) Seismic Reinforcement Part 2 ■ Contractor: Daiichi Construction Industry Co., Ltd. ■ Product Name: Liner Plate (t2.7×2,500×6,425×H=7.5) *For more details, please download the PDF or feel free to contact us.
