伏び（伏せび、伏樋）の管口から途中までの補修
鉄道と道路が並行している場合、横断する鉄道排水設備（伏び、伏せび、伏樋）の維持･管理責任は、それぞれが管轄する管理責任時範囲に限定されるのが通例です。しかし、従来の工法では隣接管理者と協議の上で全スパンを修繕しており、コストが高くなる場合がありました。伏びの管口から途中までを修繕できる「FCRライナー工法（途中対応） 」を開発致しました。 ※詳しくはPDFダウンロードまたはお気軽にお問い合わせください。

Repairing the hidden pipe with different diameters on the left and right as it is.
Due to the expansion of single-track lines to double-track lines and the construction of roads parallel to the railway, numerous railway drainage systems (such as inverted siphons and inverted pipes) with different diameters on the left and right sides have been installed. In conventional methods, the lining was adjusted to fit the smaller diameter, and mortar was injected into the gaps to complete the work. We have developed the "FCR Liner Method (for different diameters)" that allows for repairs of inverted siphons with different diameters without changing their original size. *For more details, please download the PDF or feel free to contact us.

Repairs can be made if the construction vehicle can approach within 300 meters.
The FCR Method Association uses the FCR Liner Method (standard type) for repairs of drainage facilities (flumes, flaps, and troughs) based on the conditions of camera inspections. The development of a dedicated repair method for flumes has resolved issues associated with traditional repairs that directly utilized methods designed for sewer systems. This allows for the repair of damaged flumes, stopping the inflow of soil and preventing the occurrence of subsidence accidents. *For more details, please download the PDF or feel free to contact us.*
Safer and faster! Renewing and strengthening Japan's underground with new technology.
The "SW Liner Method" is a pipe rehabilitation method that involves winding a rigid polyvinyl chloride strip in a spiral manner inside an existing pipe to create a new pipe, and filling the gap between the new and existing pipes with a filler material, thereby rehabilitating the pipe as a composite structure. Since it can be constructed without stopping the water supply (the water flowing through the pipeline), there is no need for water replacement work. The adhesive is automatically supplied simultaneously with the pipe manufacturing process. This allows for the application of adhesive at the joint sections, forming a highly watertight integrated rehabilitation pipe. 【Features】 ■ Construction is possible even under water supply conditions ■ Continuous structure without joints ■ Can be constructed without support structures as a countermeasure against buoyancy during filling ■ Pipe manufacturing using a powerful push-type method *For more details, please download the PDF or feel free to contact us.

Repair within the track closure interval.
In cases where there is inflow, leakage, or deformation in the drainage pipes of sections that can only afford a few hours of track closure within urban station premises, it was difficult to complete repairs in a short time. We have developed the "FCR Liner Method (short curing type)" that allows for repairs to be completed quickly. *For more details, please download the PDF or feel free to contact us.
Construction is possible even under shared conditions! It has been developed to minimize work inside the pipe.
The method is a speedy and economical spiral-wound pipe rehabilitation technique. Since it can be constructed without stopping the flow in use, if repairs to the existing pipes are necessary based on prior investigations, the work can be carried out promptly without impacting local life. It has been developed to enable rehabilitation of large-diameter pipes with a diameter of 800mm or more, which often face many issues, without excavation and while allowing shared water to flow, as well as minimizing work inside the pipe. [Features] ■ Construction is possible even under shared conditions ■ Continuous structure without joints ■ Compact construction equipment ■ Reduction of work inside the pipe is possible ■ Speedy and economical *For more details, please refer to the PDF document or feel free to contact us.
![FCR Liner Method (Large Diameter Compatible) [FCR Method Association]](https://image.www.ipros.com/public/product/image/e3d/2000693166/IPROS30789015141167808015.jpeg?w=280&h=280)
Repair of buried pipes with a diameter of 800 mm or more and bridge repairs.
The FCR liner method was aimed at drainage systems for railways (culverts, inverted siphons, and drainage ditches) up to Φ750, which account for 95% of such systems. However, there are some culverts and bridges on the Shinkansen and conventional lines with larger pipe diameters, and issues with these culverts and bridges could lead to major accidents. We have developed the "FCR liner method (large diameter compatible)" that can repair large diameter culverts and bridges. *For more details, please download the PDF or feel free to contact us.
