Sewer Pipe Rehabilitation Method: "Polyethylene Compact Pipe Method"

Sewer Pipe Rehabilitation Method: "Polyethylene Compact Pipe Method"

Rehabilitation methods that address ground deformation caused by earthquakes and bending due to ground subsidence.

The "Polyethylene Compact Pipe Method" involves pulling a C-shaped high-density polyethylene pipe, wound on a drum, into an existing pipe through a manhole. It is restored to a circular shape using steam heating and compressed air, tightly adhering to the existing pipe, and is a method for rehabilitating aging existing pipes. The method is primarily designed for construction with diameters ranging from φ200 to φ350mm. It possesses self-supporting pipe strength and has a high elongation rate of over 350% at the time of fracture, making it capable of accommodating ground deformation and bending caused by earthquakes and ground subsidence. Since the rehabilitation material itself is resistant to breaking and cracking, it is suitable for seismic retrofitting. 【Features of Polyethylene Compact Pipe】 ■ Uses polyethylene that is very stable in quality and environmentally friendly ■ Rehabilitation material that can be used not only for sewer systems but also for water supply systems ■ Easy quality control of materials allows for speedy construction ■ Capable of accommodating ground deformation and bending caused by earthquakes and ground subsidence ■ Has the ability to conform to existing pipes *For more details, please refer to the PDF document or feel free to contact us.

Seamless main pipe and attachment pipe integrated hardening

Seamless main pipe and attachment pipe integrated hardening

By rehabilitating the existing main pipe, connection pipe, and connection pipe joints with light curing, it is possible to achieve a uniform and seamless strong integration rehabilitation of the main pipe and connection pipe.

The seamless system construction method allows for the rehabilitation of existing main pipes, service pipes, and service pipe joints, enabling a strong integration rehabilitation of the main and service pipes. Additionally, the rehabilitated pipes use light-curing resin that hardens reliably when exposed to light (ultraviolet), providing performance equivalent to new pipes. It can accommodate main pipes with diameters ranging from Ø200 to 800 mm (self-supporting pipes from Ø200 to 600 mm). There are two types available: standard and fast-curing. **Features** - Uniform and reliable curing of rehabilitated pipes made possible by light. - The evolved seamless system leads the way in pipe rehabilitation. - Protecting the sewer system that has supported comfortable living for many years. - Aging pipes that have exceeded their useful life are increasing, particularly in urban areas. - Aging sewer pipes can cause leaks and unknown inflow of water in various locations, potentially leading to road collapses. The door to the era of pipe rehabilitation has already been opened. - Rehabilitation of sewer pipes is carried out reliably and swiftly. - By exposing to light (ultraviolet), a uniform, reliable, and seamless rehabilitated pipeline is achieved. **Applications** - Reconstruction and prolongation of the lifespan of aging or damaged sewer pipes.

Pipe rehabilitation method "Alpha Liner H Method"

Pipe rehabilitation method "Alpha Liner H Method"

Self-supporting pipes up to a diameter of 900mm are possible! A pipe rehabilitation method that has a longer material storage period and achieves further thin-walling.

The "Alpha Liner H Method" involves pulling the Alpha Liner H into an existing pipe, expanding it using air pressure to make it adhere closely to the inner surface of the existing pipe, and then irradiating it sequentially with light of a specific wavelength from the pipe opening to cure the resin. By improving the materials used in the conventional Alpha Liner, the long-term bending elastic modulus has been increased from 9,500 N/mm² to 12,000 N/mm², achieving even higher strength. Additionally, with the improvement in long-term bending elastic modulus, the material of the Alpha Liner becomes thinner. Moreover, it inherits the characteristics of the conventional Alpha Liner, allowing for shape confirmation before curing, construction that is not affected by environmental temperature, and minimizing traffic restrictions, noise control, and CO2 emissions during construction. 【Features】 - Not affected by environmental temperature - High strength (long-term bending elastic modulus: 12,000 N/mm²) - Shape confirmation can be done before curing - Capable of manufacturing materials over 100m - Short construction time *For more details, please refer to the PDF document or feel free to contact us.
