Preventing manhole uplift! An environmentally friendly method that does not require road surface excavation!
The "Inner Weight Method" is an environmentally friendly construction method that does not involve excavation of the ground among weight-increasing methods. By increasing the weight inside the manhole, it prevents the manhole from floating. It can be applied to various shapes, including existing and newly constructed assembled manholes, cast-in-place manholes, square, rectangular, circular, and oval shapes. It is possible to supplement the insufficient weight when designed using excessive pore water pressure dissipation methods, weight methods, and anchor methods with inner blocks. 【Features】 ■ Simple principle ■ Reliable effect ■ Easy construction ■ Minimal construction nuisance *For more details, please refer to the PDF materials or feel free to contact us.
