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.

[Construction Technology Examination Certificate] Self-supporting manhole rehabilitation No. 1-4, 10m, suitable for short construction.

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).

[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.

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"

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.
