An auxiliary tunneling apparatus includes a reaction force receiver and first and second split components. In the excavation of a second tunnel by a boring machine, the reaction force receiver forms a replacement face of a side wall of the second tunnel on a first tunnel side where the first and second tunnels intersect each other, and a gripper of the boring machine pushes against the replacement face. The first and second split components are installed to push against the side wall of the first tunnel, support the reaction force receiver within the first tunnel, and move back and forth with respect to the side wall of the first tunnel.

A tunnel excavation device includes a main body a frame and a workbench. The main body includes a front body section and a rear body section. The front body section includes a cutter head provided with a plurality of disk cutters. The rear body section is disposed behind the front body section and includes a gripper section for obtaining a reaction force when excavating. The frame is disposed continuously behind the main body. The workbench is disposed above the frame so as to be rotatable with respect to the frame.

A tunnel excavation device includes a front body portion configured to support a cutter head and a rear body portion. The rear body portion includes a gripper carrier and a gripper portion. The gripper carrier is disposed in a rear of the front body portion. The gripper portion is provided on the gripper carrier. The gripper portion includes a groove portion and a wheel portion. The groove portion is formed in a recess shape toward the rear main body. The wheel portion is disposed in the groove portion.

The present disclosure relates to a tunnel excavation apparatus to which a spectroscopic analysis method is applied. The tunnel excavation apparatus to which a spectroscopic analysis method is applied may include a ground component measurement unit to measure the properties of the ground which is excavated, and control a first driving unit and a second driving unit to be operated on the basis of the measured information on the ground, thereby preventing cracks from occurring on the ground during a ground excavation process.

A Tunnel Boring Machine (TBM) with a circular cutting profile includes secondary cutterhead components that produce a semicircular-arched tunnel profile for use in underground mining and/or civil construction operations, e.g., for boring in material containing rocks with Unconfined Compressive Strength (UCS) of up to 200 MPA or stronger. The machine is particularly suited to excavate long access tunnels, mine development drifts, road tunnels, and other types of tunnels that require flat bottom, semicircular-arched profiles. The substantially flat tunnel floor allows immediate and effective use of standard vehicles for material and crew transport as well as other construction and mining activities.

An apparatus for excavating a tunnel includes a cutting wheel equipped with measuring modules of sensor means on its cutting wheel face in order to directly sample the consistency of the material present between the cutting wheel face and a tunnel face by recording different types of measured values characteristic of this.

A tunnel excavation device includes a front body section and a rear body section. The front body section includes a cutter head, a cutter head support, peripheral plates, a roof shoe, and side shoes. The cutter head includes a plurality of roller cutters. The cutter head support supports the cutter head. The peripheral plates, the roof shoe, and the side shoes are provided to the outer circumference and can be collapsed inward. The rear body section is disposed to the rear of the front body section. The rear body section includes a gripper section. The gripper section obtains a reaction force for performing excavation.

The invention discloses a tunnel boring machine (TBM) equipped with a high-pressure water jet cutting system and a combined tunneling method, comprising a TBM body, the water pump unit on the body, and the high-pressure water jet cutting system at the front end of the body. The high-pressure water jet cutting system comprises a water jet-mechanical combined cutter head, water jet-shell knife combined cutters, a high-pressure water pipeline, a multi-medium rotary center, and a water jet diversion valve block. The high-pressure water at the pump unit is transmitted to the multi-medium rotary center through the high-pressure water conveying pipeline, and then divided into multiple paths by the water jet diverter valve block, and respectively supplied to each of the combined cutters on the water jet-mechanical combined cutter head. This invention offers practical suggestions and references for the overall design, and spatial arrangement of the high-pressure water jet cutting system.
