Pipe Rehabilitation Method

Pipe Rehabilitation Method

Construct a strong composite pipe that integrates existing pipes, backfill materials, and profiles. It restores the functionality of the pipeline.

This technology is a method that can rehabilitate various aging pipelines, such as sewer systems, agricultural water, and industrial wastewater, without excavation. A pipeline is formed inside the existing aging pipe using hardened PVC profiles, and a backing material is injected into the gap. Since it can be constructed "while flowing water in any cross-sectional shape without excavation," it has minimal impact on traffic and citizens' lives. Additionally, both construction time and costs can be significantly reduced compared to traditional excavation methods, making it highly suitable for modern social and economic environments. 【Features】 ■ Can rehabilitate various aging pipelines without excavation ■ Minimal impact on traffic and citizens' lives ■ Significant reduction in construction time and costs compared to excavation methods ■ Contributes to cost reduction and shortening of construction periods with methods tailored to the environment of each construction site *For more details, please refer to the PDF materials or feel free to contact us.

[Case Study] Rehabilitation of Sewer Manholes

[Case Study] Rehabilitation of Sewer Manholes

Introducing case studies aimed at the rehabilitation of manholes affected by hydrogen sulfide corrosion.

We would like to introduce a case where "D-Hole (Docking Hole)" was implemented for the rehabilitation of sewer manholes. In the Water and Sewerage Department of the Yakage Town Hall in Okayama Prefecture, measures were being taken for areas where hydrogen sulfide corrosion was significantly advanced. This time, they adopted the D-Hole using the "Cassette Method," which is gaining attention as a new construction method. [Evaluation] ■ Although it was the first adoption, a certain level of effectiveness was confirmed in terms of method, construction period, and cost, so they expressed a positive intention to consider further adoption in the future. *For more details, please refer to the PDF document or feel free to contact us.

Omega Liner Method for Rehabilitation of Pipelines Using Rigid Polyvinyl Chloride Pipes

Omega Liner Method for Rehabilitation of Pipelines Using Rigid Polyvinyl Chloride Pipes

A rigid polyvinyl chloride pipe with shape memory properties folded in an omega (Ω) shape is rapidly restored to a circular form by heating it within an existing pipe, thereby constructing a self-supporting pipe.

A rigid polyvinyl chloride pipe with shape memory performance, pre-folded into a ω shape at the factory, is pulled into the existing pipe and restored to a circular shape by heating with steam. It is then closely adhered to the existing pipe using compressed air to construct a strong self-supporting pipe. Since the liner material is a polyvinyl chloride pipe with shape memory performance, there are no chemical reactions on-site, allowing for safe construction. **Features** - Short construction time (restores to a circular shape quickly with just heating). - Consistent quality due to factory production. (Manufactured at a factory certified by the Japan Sewage Works Association and registered as Class II materials) - High seismic resistance recognized through construction technology review certification for compatibility with existing pipes. - Rehabilitates as a self-supporting PVC pipe with excellent strength, durability, corrosion resistance, and hydraulic properties. - Enables shortening of construction periods and cost reduction. - A safe construction method that does not use organic solvents, eliminating concerns about odors or fire hazards. - Follows the bends and steps of existing pipes without wrinkles, allowing for rehabilitation of only the installation pipe. **Applications** - Reconstruction and extension of the lifespan of aging or damaged sewer pipes (Ø150 to 450) - Strength restoration - Improvement of water-tightness against infiltrating water, flow characteristics, corrosion resistance, prevention of root intrusion, and seismic resistance.

Seismic Level 2 compliant, self-supporting manhole rehabilitation method "VertiLiner Method"

Seismic Level 2 compliant, self-supporting manhole rehabilitation method "VertiLiner Method"

Overwhelmingly fast construction! Reconstructing and extending the lifespan of concrete corrosion caused by hydrogen sulfide and aging manholes using FRP rehabilitation materials that allow for adjustable wall thickness.

The Bertiliner method is a technique for rehabilitating concrete that has been corroded by hydrogen sulfide and aging manholes using FRP rehabilitation materials. This method consists of FRP rehabilitation materials, a load-bearing ring, and supporting mortar, and the live loads and superimposed loads acting on the manhole are transmitted from the load-bearing ring through the FRP rehabilitation material and then through the supporting mortar to the base slab. Additionally, by using acid-resistant glass fibers and light-curing resins in the rehabilitation material, high-strength rehabilitated manholes can be formed in a short time. The thickness of the FRP rehabilitation material can be designed according to site conditions, allowing for the selection of efficient rehabilitation materials. **Features** - Self-supporting, not relying on the strength of existing manholes - Overwhelmingly fast construction - Integrated rehabilitation of sloped and vertical walls - Complies with seismic levels 1 and 2 **Applications** - Reconstruction and extension of the lifespan of aging or damaged manholes - Types: Prefabricated and cast-in-place - Shapes: Circular Φ900, Φ1000 - Manhole depth: 5m

Sewer Composite Manhole Rehabilitation Method "Eba Sheet Method"

Sewer Composite Manhole Rehabilitation Method "Eba Sheet Method"

Long-lasting corrosion-resistant manholes! A sewer composite manhole rehabilitation method that achieves material savings.

The "Evashito Method" is a composite manhole rehabilitation technique that involves installing an "FRP sheet" on the corroded inner wall of an existing manhole using an expansion frame, and filling the gap between the sheet and the existing manhole with mortar. The backside treatment of the FRP sheet creates a rough surface with the adhered silica sand, enhancing the adhesion strength with the filling material and achieving a complete integration with the existing manhole, resulting in strong durability. No heavy machinery is required, and no special skills are needed, allowing for construction in a small road occupancy area. By utilizing the existing manhole, material savings are achieved, along with a reduction in construction time, making it highly economical. 【Features】 ■ High quality ■ High speed ■ Low cost ■ Can be constructed in a small road occupancy area ■ Achieves material savings by utilizing existing manholes *For more details, please refer to the PDF document or feel free to contact us.
