The power control module 702 comprises a main control room, an oil pump, an electrical cabinets, a transformer, an air compressor, a pumping station, a power cable, a communication cables and cable reel, which provides power source, system control, sealing and lubrication to all the devices of the machine. The ventilation and water passage module 703 comprises a fan, air duct formed inside the hollow portion of the center pillar and clean water pipe. The fan is installed at an inner side of the center pillar. The center pillar is function as an air dryer to blow the polluted air below the well surface to flowing outside the shaft rapidly, that this design is compact and has high air passage efficiency. The piping such as the water pipe and cable is directly installed around the center pillar and is extended together with the center pillar, that the piping extension is simple and fast. The sinking pump 701 is directly hanged at a bottom portion of the machine through the stabilizing vehicle for sinking pump 705 at an upper portion of the derrick. The sinking pump 701 has independent suspension system and transportation passage. The sinking pump 701 has a water inlet which penetrates through the retractable shield to the slurry storage of the cutter head and is arranged for emergent water discharge. The stabilizer 704 is installed in the mounting base for stabilizer of the center pillar, and is arranged for stabilizing the center pillar and the entire machine during the process of excavation. The flat car for shaft cover 706 is installed independently on a rail of the ground surface for closing the opening of the shaft, and is used to support the loading of different devices when the center pillar is extending, and processing piping extension by using the crane for pillar 306 to lift the spare pillar 707.

The process of the present invention is as follows:

The main equipment is hanging onto the derrick 3 which is mounted on the ground surface through the center pillar 1. Through the lifting cylinder 304, the sliding frame 302 and the pillar for sliding frame 303 of the derrick, the upward and downward movement of the entire machine is controlled, and the lifting or forward excavation process of the equipment is realized. During excavation, the retractable shield 402 is firmly secured to the wall through gripping by the shield cylinder 406 to stabilize the cutter head 401 and provide anti-torque to other equipment. The gripper cylinder 411 provides gripping force to the gripper 410 to secure onto the wall, thus providing auxiliary anti-torque to the retractable shield to prevent rotational movement of equipment during the excavation process. The main driver 404 is started to drive the cutter head 401 to process excavation and rock breaking and the lifting cylinder 304 on the ground surface is used to control the applied pressure of the cutter head 401 to realize high efficient excavation process. The rock fragment resulted from cutting action of the cutter head 401 is carried by the high speed flowing slurry and is transported by the slurry pump 501 through pumping to the slurry treatment station. Through the primary vibrating screen, 504, the secondary vibrating screen 505, the tertiary vibrating screen 506, the primary hydrocyclone device 507 and the secondary hydrocyclone device 508, slag and slurry are separated and are arranged to store inside the muck storage 509 and the slurry storage tank 510 respectively. The slag inside the muck storage 509 is loaded into the bucket 512 rapidly through the rapid feeding device 511 at its bottom portion, transported outside to the ground surface through the main hoist 513, and then loaded to a vehicle through the muck chute 309 to transport to a predetermined location. The slurry stored inside the slurry storage tank 510 is backflow to the cutter head through the slurry return pipe 515 for carrying out another cycle, thus a continuous slag removal process is achieved. The highly concentrated slurry deposited on the bottom of the slurry storage tank 510 is transported to the treatment station on the ground surface through the transportation pump 516. The deterioration of slurry after a long period of usage in the shaft bottom will occur and require a replacement of new and quality slurry, which is transported through the pipe for slurry inflow 109 of the center pillar and the slurry input pipe 518 to the slurry storage tank. The slurry after deterioration is pumped out through the transportation pump 516. Thus the replacement of slurry is completed to meet the construction need.

During the excavation process of the equipment, construction steps such as manual binding of steel, anchoring, spraying and casting steps are processed at the same time. The auxiliary hoist 514 is used to transport the materials required for wall support downward to the shaft. The material hoist 614 is used to distribute the materials to different construction sites. The multifunctional rig 612 is utilized for anchoring construction, manual binding is carried out for steel binding to construct the steel arch, then the shotcreting manipulator 613 is employed for carrying spraying for wall support such that incidences such as wall collapse is prevented. In the rear portion of the equipment, process secondary binding of steel and install the concrete sealing ring 608, transport the module board 602 by utilizing the auxiliary crane 601 and process casting. Then, connect the grouting pipe 607, transport concrete from the ground surface through the concrete pipe 106, the transportation concrete pipe 603 and the buffer 604 to the concrete mixing tank 605 in the shaft. Thereafter, the concrete is pumped through the concrete pump 606 to transport to an inner portion of the module board to complete the wall casting process.

During the construction process, advanced geological survey is conducted by utilizing the multi-functional rig 612. If special strata is encountered, the multi-functional rig 612 and the grouting pump 615 are used to carrying out grouting reinforcement for the sides of the wall and the front of the machine. The geological condition is improved and the construction safety is ensured.

As the equipment is processing excavation continuous at a downward direction, after the particular stroke of the lifting cylinder 304, the center pillar 1 and the auxiliary pipelines is completed, an extension process of the center pillar is required. Utilize the flat car for shaft cover 706 to lock the flange of the center pillar, remove the connecting bolts, move the sliding frame 302 at a upward position, disconnect the center pillar 1, hoist the spare pillar 707 rapidly through the crane for pillar 306 and utilize the manipulator for pillar 307 to precisely control and complete the docking of pillars. Thus, the extension of the center pillar 1 and other pipelines is processed. There is no need to transport the pipelines to the bottom of the shaft, the operation is convenience and highly efficient.
