Manhole Floating Prevention Method "WIDE Safety Pipe Method"
Installation is possible in existing manholes without the need for excavation work. Construction can be carried out even with a small surface area above ground. *Certificate of new technology research results obtained.
The "WIDE Safety Pipe Method" dissipates excess pore water pressure and drains it into the manhole. As a result, it is a method that suppresses the uplift of the manhole by reducing the frictional force around the manhole due to liquefaction. In the case of existing manholes, it does not require excavation work around the manhole since a collection pipe is installed from inside the manhole. Additionally, drainage into the manhole only occurs when an earthquake happens, preventing unnecessary water from flowing into the sewage system. 【Features】 ■ Jointly developed with the Japan Sewerage New Technology Promotion Organization ■ Applicable to both existing and newly constructed manholes ■ Minimizes traffic disruption ■ Performance remains unchanged even with repeated aftershocks *For more details, please download the PDF or feel free to contact us.
