  • Combined rock-breaking TBM tunneling method in complex strata for realizing three-way force detection
    Patent number: 11486249
    Abstract: Disclosed a combined rock-breaking TBM tunneling method in complex strata for realizing three-way force detection, comprising the steps of preparing a combined mechanical-hydraulic rock-breaking cutter head for TBM construction; starting construction; advancing the combined mechanical-hydraulic rock-breaking cutter head; pushing and pressing against a tunnel face by a mechanical cutter tool; subjecting a three-way force detection cutter to squeezing forces; feeding back three-way force data by a three-way force sensor; processing information by a TBM back-end control processor; obtaining a value of rock-cutter contact angle ?; feeding back parameter information to a TBM cutter head control center by a lithology index center; responding by the TBM cutter head control center, obtaining and adjusting parameters by the mechanical cutter tool equipped with the three-way force sensor; and breaking rock by the combined mechanical-hydraulic rock-breaking cutter head.
