Self-supporting manhole rehabilitation method SS Hole System 1-4, 10m!!

Self-supporting manhole rehabilitation method SS Hole System 1-4, 10m!!

Applicable to manholes with reduced residual strength, such as those with cracks!

The "SS Hole System" is a rehabilitation method that simply extends the lifespan of aging manholes. It is suitable for manholes with cracks or advanced corrosion, as well as those requiring seismic reinforcement, adapting to manholes with reduced residual strength. This method uses reliable materials that have been traditionally used, and the rehabilitation material alone provides the strength of a self-supporting pipe, excellent acid resistance, and seismic performance. Additionally, the construction method is simple, allowing all work to be carried out by local contractors. 【Applicable Conditions】 ■ For manholes with cracks ■ For manholes with advanced corrosion ■ For manholes requiring seismic reinforcement ■ For manholes with high hydrogen sulfide concentrations ■ For manholes that cannot be replaced 《Construction Technology Review Certificate (Sewage) obtained March 18, 2021, No. 2021 Scope of application expanded: Manholes No. 1 to No. 4, up to 10m deep》 *For more details, please refer to the PDF document or feel free to contact us.

Self-supporting manhole rehabilitation method 'SS Hole System' No. 1-4 up to 10m!!

Load-bearing capacity equivalent to new! A rehabilitation method that simply extends the lifespan of aging manholes.

The "SS Hole System" is a rehabilitation method for manholes that require restoration, particularly those that are severely deteriorated and cannot maintain the required strength in their current condition, or are expected to be unable to maintain strength in the future. This method provides a strength equivalent to that of newly constructed manholes. It does not require special materials or construction techniques, and it can be implemented while the sewage is in use. 【Features】 ■ Compatible with manholes of sizes 1 to 4; other sizes available upon consultation ■ Supports manhole depths of up to 10 meters; depths exceeding 10 meters available upon consultation ■ NETIS registered [QS-150045-A] ■ Simple construction using stable materials produced in a factory ■ Load-bearing capacity is equivalent to new installations *On March 15, 2019, it obtained the Construction Technology Review Certificate (Sewage) from the Japan Sewerage New Technology Organization, and on March 18, 2021, the scope was expanded to include manholes of sizes 1 to 4 and depths of up to 10 meters.* *For more details, please refer to the catalog or feel free to contact us.*

Sewer Manhole Rehabilitation Method "PML Method"

Sewer Manhole Rehabilitation Method "PML Method"

The noise from the work is low! We provide a healthy environment for those who are working.

The "PML method" is a sewer manhole rehabilitation technique that takes into consideration the surrounding residents and the contractors. A polyethylene liner, which has a low environmental impact, serves as a corrosion-resistant membrane that covers the inner surface of the pipe. Since it does not use large equipment, the noise generated during the work is minimal, and no harmful organic solvents are used, providing a healthy environment for those performing the work. [Features] ■ Stable quality ■ High acid resistance ■ Wide applicability ■ Consideration for the environment ■ Compact work with minimal noise *For more details, please refer to the PDF materials or feel free to contact us.

PML Method: A manhole rehabilitation technology with low environmental impact and minimal work noise.

PML Method: A manhole rehabilitation technology with low environmental impact and minimal work noise.

We will repair the sewage facilities using an anti-corrosive membrane made of factory-produced acid-resistant polyethylene material. Since it is a technology for installing secondary products, adjusting the construction schedule is easy.

An environmentally friendly polyethylene liner serves as a corrosion-resistant membrane. This technology produces less noise during work since it does not require large equipment. Additionally, it does not use harmful organic solvents, providing a healthy environment for workers. 【Applications】 ● Reconstruction and extension of the lifespan of aging or damaged manholes 【Features】 ● The factory-produced liner is processed into a complete single piece, ensuring very stable quality. ● Being a finished product, it can be safely stored until actual construction takes place. ● It can be postponed in case of adverse weather or if construction must be delayed. ● It has extremely high acid resistance against acids specific to wastewater environments generated by aerobic bacteria. ● Work can be carried out even during wastewater use by using special packers.
