Non-excavation and no spoil construction method for the renovation of sewer pipes, "EXP Method."

Non-excavation and no spoil construction method for the renovation of sewer pipes, "EXP Method."

A construction method that is friendly to cities and people, which involves crushing and expanding old pipes while pushing in new pipes of the same diameter or one size larger, all without excavation and without generating waste.

This is a reconstruction promotion method that crushes and expands old pipes while pushing in new pipes of the same diameter or one rank up. A hydraulic-operated expander (diameter-expanding crusher) is inserted into the existing pipe, and new pipes are pushed into the void created by the diameter expansion and crushing, allowing for a non-excavation and soil-free construction method that is friendly to both cities and people. **Features** - Replacement with new pipes of the same diameter or larger at the same position as the existing pipes, improving flow performance. - Since the method expands and crushes the existing pipes from the inside without excavation, there is no generation of excavated soil or industrial waste. - Analysis confirms that there is no significant ground deformation affecting the surrounding soil. - It can adapt to step differences and bends at the joint sections, allowing for the replacement of deformed PVC pipes and similar with new pipes. - The use of concrete pipes, PVC pipes, and resin concrete pipes for new installations ensures high quality and durability. **Applications** - Reconstruction and extension of aging or damaged sewer pipes (Ø150–Ø600). - Strength restoration. - Improvement of water-tightness against infiltration, flow performance, corrosion resistance, and prevention of tree root intrusion. - When there is a desire to secure a larger flow capacity than the existing pipes. - When considering the replacement of existing pipes but wanting to control disposal costs.

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
