Sewer Composite Manhole Rehabilitation Method "Eba Sheet Method"

No special skills required! A sewer composite manhole rehabilitation method that can be constructed with a small road occupancy area.

The "Evashito Method" is a composite manhole rehabilitation technique that involves attaching an "FRP sheet" to the inner wall of an existing manhole that has advanced corrosion, using an expansion frame, and filling the gap between the sheet and the existing manhole with mortar. With a thickness of 1.5mm for the FRP sheet, the method promises increased longevity through enhanced corrosion resistance and durability, while the filling material, a non-shrink mortar, maintains strength over the long term. Additionally, there is no need for heavy machinery, and no special skills are required, allowing for construction in a small road occupancy area. By utilizing the existing manhole, material savings are achieved, resulting in excellent economic efficiency along with shortened construction periods. 【Features】 ■ Demonstrates strong robustness through complete integration with the existing manhole ■ Filling material maintains strength over the long term with non-shrink mortar ■ Can be constructed in a small road occupancy area ■ Achieves material savings by utilizing the existing manhole ■ Passes acid resistance and sulfur intrusion tests *For more details, please refer to the PDF document or feel free to contact us.

A self-supporting manhole rehabilitation method that has received construction technology examination certification maintains strength equivalent to that of a newly installed manhole! Here is an explanation of the construction procedure.

For manholes that require rehabilitation, particularly those that are severely deteriorated and are expected to be unable to maintain the required strength in their current condition, we have developed a rehabilitation method called "SS Hole," which has the same strength as newly installed manholes. 【Construction Procedure】 1. Remove the deteriorated manhole up to the sloped wall. ↓ 2. Clean and remove the vertical walls and invert of the existing manhole. ↓ 3. Install a "reinforced plastic composite pipe" certified by the Sewer Association into the existing manhole (compatible from size 1 to size 4). ↓ 4. Fill the gap between the reinforced plastic composite pipe and the vertical wall of the existing manhole with backfill material. ↓ 5. Install the foundation block for the SS Hole. ↓ 6. Install the slab block for the SS Hole. ↓ 7. After installing the sloped wall, adjustment ring, and iron cover, backfill to complete. *Construction takes approximately 4 to 5 days (depending on conditions).

The "SS Hole System" is a rehabilitation method that simply extends the lifespan of aging manholes. Being self-supporting, it does not require the residual strength from diagnostic surveys of existing manholes and can also accommodate unreinforced manholes, providing a load-bearing capacity equivalent to new installations. This method does not require special construction techniques, allowing for rehabilitation using general construction skills anywhere in Japan. As a factory-produced product, it has consistent quality with no variability and stable load-bearing capacity. The internal cross-section is maximally secured. 【Features】 ■ Constructability: Does not require special construction techniques, allowing for rehabilitation with general construction skills. ■ Acid Resistance: Reinforced plastic composite pipes with over 40 years of proven performance. ■ Load Capacity: Factory-produced, ensuring consistent quality and stable load-bearing capacity. ■ Seismic Resistance: Reinforced plastic composite pipes with high strength and excellent seismic resistance. 《Acquired the Construction Technology Review Certificate (Sewage) from the Japan Sewerage New Technology Organization 　March 18, 2021, No. 2021 　Scope of expansion: Manholes No. 1 to No. 4, up to a depth of 10m》 *For more details, please refer to the PDF materials or feel free to contact us.

Introduction of standard construction procedures for obtaining inspection certification for self-supporting manhole rehabilitation methods!

No special materials or construction techniques are required, and it can be completed in a short period of about 4 to 5 days! Here is an introduction to the construction procedure of the SS Hall system!

The "SS Hole System" is a rehabilitation method that simply extends the lifespan of aging manholes. Depending on the conditions, it can be completed in a short construction period of about 4 to 5 days! The construction steps are as follows: 1. Clean and remove the deteriorated sloped walls of the manhole, the vertical walls of the existing manhole, and the invert. 2. Install the "Reinforced Plastic Composite Pipe Manhole" into the existing manhole, filling the gap between the reinforced plastic and the vertical wall of the existing manhole with backfill material. 3. Install the foundation block and slab block of the SS hole, then backfill after installing the sloped walls, adjustment rings, and iron covers to complete the process. 《Construction Technology Examination Certificate (Sewage) obtained March 18, 2021, No. 2021 Scope of application expanded: Manholes No. 1 to No. 4, up to a depth of 10 meters》 *For more details, please refer to the PDF document or feel free to contact us.
