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 cannot secure the required strength in their current condition, or are expected to be unable to secure strength in the future, we have developed the "SS Hole" as a rehabilitation method that has strength equivalent to 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 the "reinforced plastic composite pipe" certified by the Sewerage Association into the existing manhole (compatible with sizes 1 to 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 duration is approximately 4 to 5 days (depending on conditions).
