Sewer assembly manhole "Pre-Hole"

Installation is easy and can be done quickly.

The "Pre-Hole" is a precast concrete assembly manhole for sewage systems, registered under the Class I standard (JSWAS A-11) of the Japan Sewage Works Association, utilizing an impregnation adhesive method (elastic adhesive). By employing the impregnation adhesive method with elastic adhesive, it holds the components through adhesive and shear strength, while the adhesive's properties of watertightness and toughness at the joints enhance seismic resistance, making it an economical manhole. Please feel free to contact us if you have any inquiries. 【Features】 ■ The main body is made of concrete that is forcibly compacted using centrifugal or roller compaction methods, resulting in high-strength, high-water-tight components. ■ The joints of each component utilize the impregnation adhesive method with elastic adhesive, eliminating the need for sealing rubber, gaskets, or fastening hardware. ■ The performance of the components has been verified through various tests, allowing for the creation of an ideal manhole with no misalignment or leakage at the joints. *For more details, please download the PDF or feel free to contact us.
