Recommended method for preventing manhole floatation! 【Anchor Wing Method】
Safety and security measures for manholes! No inspections, cleaning, or repairs required at all.
The "Anchor Wing Method" is a technique for preventing manhole uplift. By rotating and embedding an anchor section with spiral wings connected to rods into a stratum that poses no risk of liquefaction, and linking the rods to fixed fittings installed on the manhole head, the uplift of the manhole is physically and reliably restrained. This is a maintenance-free technology that requires no inspection, cleaning, or repairs to maintain drainage functionality over an extended period. 【Construction Flow】 ■ Removal of pavement and subgrade, excavation ■ Anchor wing set ■ Rotational embedding ■ Casing extraction *For more details, please refer to the PDF document or feel free to contact us.
