Combined rock-breaking TBM tunneling method in complex strata for realizing three-way force detection

A combined rock-breaking Tunnel Boring Machine (TBM) tunneling method in complex strata for realizing three-way force detection, comprising:

• Step 1:
• preparing a combined mechanical-hydraulic rock-breaking cutter head (1) of a combined rock-breaking TBM (17) for construction;
• Step 2:
• starting construction by the combined rock-breaking TBM (17);
• Step 3:
• propelling the combined mechanical-hydraulic rock-breaking cutter head (1);
• Step 4:
• pushing and pressing mechanical cutter tools (1.111) against a tunnel face (15);
• Step 5:
• subjecting three-way force detection cutters to squeezing forces and three-way force sensors (1.122) obtaining three-way force data, wherein the three-way force detection cutters are loaded with the three-way force sensors;
• Step 6:
• sending the three-way force data from the three-way force sensors (1.122) to a TBM back-end control processor;
• Step 7:
• processing the three-way force data by the TBM back-end control processor;
• Step 8:
• obtaining a value of a rock-cutting contact angle φ from said processing the three-way force data;
• obtaining parameter information from a lithology index center based on the value of the rock-cutting contact angle φ;
• sending the parameter information to a TBM cutter head control center;
• Step 9:
• the TBM cutter head control center responding to the parameter information;
• Step 10:
• obtaining the parameter information at the mechanical cutter tools (1.111) and adjusting the mechanical cutter tools (1.111) based on the obtained parameter information;
• and
• Step 11:
• breaking rock by the combined mechanical-hydraulic rock-breaking cutter head (1).
