TBM DIGGING PERFORMANCE TESTTING APPARATUS FOR FORE-END OF SMALL SECTION TUNNEL BORING MACHINE

摘要

Drilling test equipment for small section TBM tip is provided. This equipment includes an earthquake box in which one side is opened and a ground medium is filled in the inner space, a reaction wall installed at a position facing the earth box and spaced apart by a predetermined distance, and on the ground between the earth box and the reaction wall. A machine support is installed in the tunnel box boring machine (TBM) for excavating the ground medium filled in the vessel box, accommodates the vessel box, the tunnel boring machine (TBM) is the vessel box When excavating an internal ground medium, the tunnel supporting machine (TBM), which is connected to one end of the tunnel boring machine (TBM) to fix the vessel box so as not to move, moves the tunnel boring machine (TBM) toward the soil box, A hydraulic jack for providing a thrust force to pressurize the reaction force wall, and a control unit for generating a control signal for driving the hydraulic jack.
