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.

Provide is a method for real-time deviation monitoring of miniature pipe-roofing jacking pipes of spiral soil-discharging. The method includes: welding a measurement auxiliary pipe to an outer wall of a pipe-roofing steel pipe, providing a laser pen inside a front end of the measurement auxiliary pipe, and the laser pen emits a beam propagating from the front end to a rear end of the measurement auxiliary pipe. After installation, a male lock buckle and a female lock buckle are symmetrically welded onto the pipe-roofing steel pipe, and form an integrated structure with the pipe-roofing steel pipe. A measurement plate is fixedly mounted on a housing of a pipe-roofing drilling machine. During jacking, a change of a position of the beam on the measurement plate is observed to determine a deviation of a drill bit of the pipe-roofing drilling machine and the pipe-roofing steel pipe in real-time.

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.

Provided a ground drilling device capable of reducing the maintenance time by suppressing wear of the rotary blade, extending the life of each component, and reducing the frequency of drilling pipes. The ground drilling device includes: the rotary blade that excavates the ground; the lubricating liquid jetting device that jets the lubricating liquid to the rotary blade when excavating the ground, and the oxygen supply device that supplies oxygen to the lubricating liquid, in which the oxygen supply device has the bubble generating medium for supplying oxygen in a high pressure state as fine bubbles to the lubricating liquid.

An energy device for shield machines disclosed by the application comprises: a trolley structure arranged behind the shield machine; a power management system arranged on the trolley structure and electrically connected with the shield machine main body; a solid-state energy cell arranged on the trolley structure; wherein, the solid-state energy cell is connected with the power management system and used for providing electric energy output; and an inverter system arranged between the power management system and the solid-state energy cell, wherein the inverter system is used for controlling the charging input or power supply output of the solid-state energy cell. The energy device for shield machines disclosed by the application is safe and environment-friendly, can replace the diesel generator as the emergency energy source of shield machines, provides stable power supply, and reduces the power consumption cost of the shield machine.

A shield cutterhead for cutting a diaphragm wall with steel I-beam comprises a cutterhead body, a plurality of main cutter beams, an auxiliary cutter beam, a central double-disc roller cutter, and a tool group. The central double-disc roller cutter is arranged at a center of a working face of the cutterhead body and connected to the plurality of main cutter beams. The plurality of main cutter beams are arranged radially along the cutterhead body. The auxiliary cutter beam is arranged between adjacent main cutter beams. The tool group is mounted on the plurality of main cutter beams and the auxiliary cutter beam. Each of the central double-disc roller cutter, the plurality of main cutter beams, and the auxiliary cutter beam are arranged in six different tiers from a center to an edge of the cutterhead body based on heights of the central double-disc roller cutter and the tool group.

A method of lining a tunnel comprises providing a plurality of injectors (7) on an apparatus, the injectors being positioned adjacent an internal tunnel surface (6) or (41) and using the injectors to place and compress and, if required, crush the solid particles of, and dewater the lining material (5) to form a structural tunnel lining. The apparatus is moved forward by the pressure exerted by the injectors (7) as they discharge the lining material. Articulated shuttering for the tunnel lining is provided on a trailing side of the apparatus. The injectors (7) can be arranged on an apparatus having a cross-section corresponding to a cross-section of a tunnel to be lined.

The present invention discloses a movable visual inspection device for shield machines, comprising a rail and an inspection platform. The rail is installed on a shield tail, and the inspection platform includes a bottom plate, a shell, a cleaning mechanism, a power storage control system, and a traveling mechanism. Inside the shell is a visual inspection mechanism with a camera box, a camera, and a stabilizer component. The traveling mechanism drives the bottom plate along the rail. The cleaning mechanism, consisting of a glass sheet, a reel driving part, and a cleaning film, keeps the camera lens clear. The reel driving part rotates the cleaning film, which slides against the glass sheet on the camera box. This invention enables multi-faceted and multi-angle visual inspection of shield machine segments, ensures a clear camera lens, facilitates automatic cleaning and inspection position adjustment, and enhances working efficiency and inspection effectiveness.
