Description

Technical Field

[0001] This invention relates to the field of shaft excavation equipment, specifically a shaft tunneling machine, an installation method for a shaft tunneling machine, a working method for a shaft tunneling machine, and a disassembly method for a shaft tunneling machine. Background Technology

[0002] Currently, the construction of pumped storage shafts involves significant excavation requirements. Most power station water conveyance systems under construction employ a multi-stage shaft or inclined shaft layout for their water diversion tunnels. Common construction methods include reverse drilling or drilling with a lifting shaft to create a pilot shaft, followed by conventional drill-and-blast excavation. These methods suffer from drawbacks such as difficulty in quality control, slow excavation speed, high safety risks, and a poor working environment, posing significant occupational health risks to on-site construction and management personnel.

[0003] To address the aforementioned shortcomings, Chinese Patent CN114278305A, published on April 5, 2022, discloses a "Drilling Machine for Enlarged Holes and its Construction Method," which solves the problems of poor working conditions, high labor intensity, and slow construction progress in traditional shaft construction. Given a known guide shaft, it can drill and excavate a shaft in one go, simultaneously completing the shaft wall lining. However, since most water diversion shafts require excavation within a chamber, the drilling machine for enlarged holes needs to enlarge the chamber during the installation of the shaft frame, resulting in increased construction costs and extended construction time. Summary of the Invention

[0004] To address the issue of increased construction costs caused by the need for enlarged chambers when installing the derrick of the aforementioned expanded-hole shaft tunneling machine, this invention provides a shaft tunneling machine and its installation, operation, and disassembly methods. The shaft tunneling machine eliminates the traditional derrick design, has a small assembly and disassembly space, and facilitates the assembly and disassembly of the expanded-hole shaft tunneling machine in confined spaces.

[0005] The technical solution adopted by the embodiments of the present invention to solve its technical problem is as follows:

[0006] A shaft tunneling machine includes a hoisting top beam system and a reaming shaft tunneling machine arranged vertically. The reaming shaft tunneling machine includes a main system, a hoisting platform assembly, and a rear support system. The main system is located below the hoisting platform assembly, and the rear support system is installed on the hoisting platform assembly.

[0007] The beneficial effects of the above technical solution are: by using the hoisting top beam system to complete the assembly of the expanded shaft tunneling machine in the starting shaft, there is no need to expand the borehole chamber, which reduces the increase in construction costs and shortens the construction period.

[0008] The hoisting top beam system consists of a hoisting beam and a hoist connected in sequence. The hoisting beam is fixed to the top of the chamber, and the extension direction of the hoisting beam is the same as the extension direction of the chamber. The hoist can move along the extension direction of the hoisting beam.

[0009] The shaft boring machine also includes a hoisting ground beam system, which consists of a ground beam, pulley blocks, and a winch. The ground beam and the winch are both fixed to the ground of the chamber. The ground beam corresponds to the starting shaft. The pulley blocks are fixed to the ground beam. The winch winds steel strands and connects to the hoisting platform group through the pulley blocks. The winch can provide upward pulling force to the reaming shaft boring machine.

[0010] The ground beam consists of a pulley block mounting frame and a base frame that are connected vertically. The pulley block mounting frame has a material transport area in the middle. The base frame has a rectangular structure and is fixed to the outside of the wellhead of the launching well.

[0011] The shaft tunneling machine also includes a winch system, which consists of a winch, a fixed pulley, and a bucket connected in sequence by steel strands. The winch is fixed to the ground of the chamber, the fixed pulley is fixed to the top of the chamber, the fixed pulley is located directly above the opening of the starting shaft, and the bucket can pass through the material transport area.

[0012] The shaft boring machine also includes a turntable system, which is located between the hoisting ground beam system and the reaming shaft boring machine. The turntable system includes a turntable support beam, a turntable support plate, and a ladder. The end of the turntable support beam is inserted into the shaft wall of the starting shaft, the turntable support plate sits on the turntable support beam, and the ladder connects the ground beam and the turntable support plate.

[0013] The shaft boring machine also includes a platform support beam, which is located between the main system and the platform assembly. The end of the platform support beam is inserted into the shaft wall of the starting shaft, and the platform assembly can sit on the platform support beam.

[0022] 8a. The hoisting ground beam system moves the expanded shaft tunneling machine upward, removes the support beam of the hoisting platform group, and assembles the shaft tunneling machine.

[0023] The advantages of the above technical solution are: the assembly and disassembly of the reaming shaft tunneling machine can be completed in the launching shaft using a hoisting top beam system, which requires little space for assembly and disassembly, facilitating the assembly and disassembly of the reaming shaft tunneling machine within a confined space. It eliminates the need for a separate reaming chamber, reducing construction costs and shortening the construction period.

[0024] A method for operating a shaft tunneling machine, wherein the shaft tunneling machine is the aforementioned shaft tunneling machine, the method for operating the shaft tunneling machine includes the following steps:

[0025] The shaft excavator digs downwards, leaving a central soil area in the lower tunnel. The central soil area has an open ring structure, and its axis coincides with the axis of the shaft guide tunnel. The opening of the central soil area faces the entrance or exit of the lower tunnel.

[0037] The beneficial effects of this invention are: the shaft boring machine eliminates the traditional derrick design, requiring less space for assembly and disassembly, facilitating the assembly and disassembly of the expanded-hole shaft boring machine within confined spaces. It eliminates the need for an expanded-hole chamber, reducing construction costs. Attached Figure Description

Figure 1 The orientation term refers to the surface of the paper and points outwards from the paper. This invention is described from the perspective of a reader or user, but the aforementioned directional terms should not be construed as limiting the scope of protection of this invention.

[0057] like Figure 1 As shown in the figure, a shaft tunneling machine according to an embodiment of the present invention includes a hoisting top beam system 2 and a reaming shaft tunneling machine 1 arranged vertically. The reaming shaft tunneling machine 1 includes a main machine system 101, a hoisting platform assembly 102 and a rear supporting system. The main machine system 101 is located below the hoisting platform assembly 102, and the rear supporting system is installed on the hoisting platform assembly 102.

[0058] The described shaft boring machine eliminates the traditional derrick design, utilizing a hoisting top beam system 2 to assemble and disassemble the reamed shaft boring machine 1 within the starting shaft 7. This minimizes the assembly and disassembly space, facilitating assembly and disassembly within confined areas. The elimination of the need for a separate reaming chamber reduces construction costs and shortens the construction period.

[0059] like Figure 1 and Figure 2 As shown, the hoisting top beam system 2 includes a crane beam 201 and a crane 202 connected in sequence. The crane beam 201 is fixed to the top of the chamber 8 and is connected and fixed to the upper side wall of the chamber 8. The extension direction of the crane beam 201 is the same as the extension direction of the chamber 8, and the crane 202 can move along the extension direction of the crane beam 201. The crane beam 201 and the crane 202 are connected one-to-one, and the number of crane beams 201 and cranes 202 can be determined according to needs. For example, there can be two crane beams 201 and two cranes 202. The main function of the hoisting top beam system 2 is to hoist the components of the reaming shaft tunneling machine 1 into the launching shaft 7 to assemble the reaming shaft tunneling machine 1, and to disassemble the reaming shaft tunneling machine 1 into components and hoist them out of the launching shaft 7.

[0060] like Figure 1 and Figure 3 As shown, the shaft boring machine also includes a hoisting ground beam system 3. Both the hoisting top beam system 2 and the hoisting ground beam system 3 are located within the chamber 8, and are arranged vertically. The hoisting ground beam system 3 includes a ground beam 301, a pulley block 302, and a winch 303. The ground beam 301 and the winch 303 are fixed to the ground of the chamber 8. The ground beam 301 corresponds vertically to the starting shaft 7. The pulley block 302 is fixed to the ground beam 301. The winch 303 winds steel strand 304 and connects to the lifting platform assembly 102 via the pulley block 302. The lifting platform assembly 102 contains multiple lifting platforms arranged vertically. The winch 303 provides upward pulling force to the reaming shaft boring machine 1. The main function of the hoisting ground beam system 3 is to enable the reaming shaft boring machine 1 to move vertically within the shaft.

[0061] The ground beam 301 includes a pulley block mounting frame 3011 and a base frame 3012 connected vertically. The pulley block mounting frame 3011 has a material transport area 3013 in the middle. The base frame 3012 has a rectangular structure and is fixed to the outside of the wellhead of the starting well 7.

[0062] like Figure 1As shown, the shaft boring machine also includes a winch system 4, located inside the chamber 8. The winch system 4 comprises a winch 403, a fixed pulley 404, and a bucket 402 connected sequentially by steel strands 401. The winch 403 is located outside the opening of the starting shaft 7 and is fixed to the ground of the chamber 8. The fixed pulley 404 is fixed to the top of the chamber 8 and to the upper side wall of the chamber 8, directly above the opening of the starting shaft 7. The bucket 402 can pass through the material transport area 3013. The main function of the winch system 4 is to lift the bucket 402, which is used for material transport and personnel movement; it is generally not used for equipment installation.

[0063] like Figure 1 and Figure 5 As shown, the shaft boring machine also includes a turntable system 6, located within the launching shaft 7. The turntable system 6 is situated between the hoisting ground beam system 3 and the enlarged shaft boring machine 1. The turntable system 6 comprises a turntable support beam 601, a turntable support plate 602, and a ladder 603. The end of the turntable support beam 601 is inserted into the shaft wall of the launching shaft 7. The turntable support plate 602 rests on the turntable support beam 601. The turntable support beam 601 consists of two parallel, spaced-apart horizontal beams, whose function is to support the turntable support plate 602. The ladder 603 connects the ground beam 301 and the turntable support plate 602, and is used for personnel to move up and down between the chamber 8 and the turntable support beam 601.

[0064] like Figure 1 and Figure 4 As shown, the shaft boring machine also includes a platform support beam 5. The platform support beam 5 can be located inside the launching shaft 7, between the main system 101 and the platform assembly 102. The end of the platform support beam 5 can be inserted into the shaft wall of the launching shaft 7, and the platform assembly 102 can sit on the platform support beam 5. The platform support beam 5 consists of two parallel, spaced-apart horizontal beams. The platform support beam 5 is perpendicular to the turntable support beam 601. For example, the platform support beam 5 extends in the left-right direction, and the turntable support beam 601 extends in the front-back direction. The function of the platform support beam 5 is to support the platform assembly 102 and the main system 101.

[0065] The following describes an installation method for the aforementioned shaft tunneling machine, which includes the following steps:

[0066] 1a. Excavate the launching shaft 7. The opening of the launching shaft 7 is located on the ground of the chamber 8. The launching shaft 7 contains a main unit installation section 701 and a supporting installation section 702 connected from bottom to top. The depth of the main unit installation section 701 is greater than the height of the main unit system, and the depth of the supporting installation section 702 is greater than the sum of the height of the hoisting platform assembly 102 and the height of the central turntable system 6. Before assembly, the components of the shaft tunneling machine are located inside the chamber 8.

[0067] The diameter of the launching shaft 7 is larger than the excavation size of the cutterhead of the main system 101. A first crossbeam mounting slot 703 and a second crossbeam mounting slot 704 are excavated on the side wall of the launching shaft 7. Vertically, the length of the first crossbeam mounting slot 703 is greater than the length of the second crossbeam mounting slot 704. The first crossbeam mounting slot 703 is used to install the lifting platform support beam 5. The lower end of the first crossbeam mounting slot 703 is located at the lower end of the rear-mounted installation section 702. The second crossbeam mounting slot 704 is used to install the central turntable support beam 601. The lifting top beam system 2 is installed on the upper side of the chamber 8.

[0068] 2a. The main unit system 101 is hoisted into the main unit installation section 701 using the hoisting top beam system 2.

[0069] Using the hoisting top beam system 2, the components of the main unit system 101 are hoisted into the main unit installation section 701, and the components of the main unit system 101 are assembled into the main unit system 101. For example, the cutterhead is first hoisted into the main unit installation section 701 in sections for assembly; the central column is hoisted into the well and connected to the cutterhead, and the support shoe propulsion system is hoisted into the well and connected to the central column.

[0070] 3a. Install the lifting platform support beam 5 at the lower end of the rear supporting installation section 702. The end of the lifting platform support beam 5 is inserted into the first crossbeam installation groove 703 of the starting well 7. The lifting platform support beam 5 is in a horizontal state.

[0071] 4a. Using the hoisting top beam system 2, the hoisting platform assembly 102 is hoisted in the rear supporting installation section 702, and the hoisting platform assembly 102 sits on the hoisting platform assembly support beam 5.

[0072] Using the lifting top beam system 2, each of the lifting platforms of the lifting platform group 102 is sequentially lifted into the rear supporting installation section 702. Multiple lifting platforms are assembled into the lifting platform group 102 in the rear supporting installation section 702. The lifting platform group 102 is supported by the lifting platform group support beam 5. The rear supporting system of the expanded hole shaft tunneling machine 1 can be lifted into the rear supporting installation section 702 along with the lifting platforms.

[0073] 5a. Install a turntable support beam 601 on the upper part of the rear supporting installation section 702. The end of the turntable support beam 601 is inserted into the second crossbeam installation groove 704 of the starting well 7. The turntable support beam 601 is in a horizontal state.

[0074] 6a. Using the hoisting top beam system 2, the transfer support plate 602 is hoisted into the rear supporting installation section 702. The transfer support plate 602 sits on the transfer plate support beam 601 and is supported by the transfer plate support beam 601.

[0075] 7a. Install the hoisting ground beam system 3 outside the wellhead of the starting well 7. The steel strand 304 of the hoisting ground beam system 3 is connected to the hoisting platform assembly 102, such as... Figure 1 As shown.

[0076] 8a. The hoisting ground beam system 3 moves the reaming shaft tunneling machine 1 upwards a suitable distance, and the support beam 5 of the hoisting platform assembly is removed. The depth of the main unit installation section 701 should ensure that the support beam 5 of the hoisting platform assembly can be easily removed after the reaming shaft tunneling machine 1 moves upwards. At this time, the shaft tunneling machine is assembled.

[0077] The installation method of the shaft tunneling machine is performed in the following order: 1a, 2a, 3a, 4a, 5a, 6a, 7a, 8a.

[0078] Before the shaft tunneling machine is assembled, the existing equipment has already excavated chamber 8, shaft guide tunnel 9, and lower tunnel 10 in the strata. Chamber 8, shaft guide tunnel 9, and lower tunnel 10 are connected sequentially from top to bottom. Chamber 8 and lower tunnel 10 are horizontal, while shaft guide tunnel 9 is vertical and used for lower muck removal. After assembly, the shaft tunneling machine can begin downward excavation.

[0079] The following describes a working method for a shaft tunneling machine, which is the shaft tunneling machine assembled as described above. The working method of the shaft tunneling machine includes the following steps:

[0080] After the expansion shaft tunneling machine 1 in the starting shaft 7 is assembled and debugged, the shaft excavation begins. As the main machine excavates downwards, the winch 303 lowers the steel strand, and the hoisting platform 102 is lowered. The shaft tunneling machine continues to excavate downwards. If, after the lower tunnel 10 is cleared, the remaining rock before the expansion shaft tunneling machine 1 reaches the receiving end (in the lower tunnel 10) is insufficient to support the weight of the machine, posing a risk of the entire machine falling. Measures must be taken at the bottom to provide supporting reaction force to ensure the smooth reception of the machine.

[0081] When excavating the lower tunnel 10, a central soil area 1001 can be left within the lower tunnel 10, such as... Figure 6 As shown, the central soil region 1001 is an open ring structure. The axis of the central soil region 1001 coincides with the axis of the vertical shaft guide tunnel 9. The opening of the central soil region 1001 faces the entrance of the lower tunnel 10, for example, to the right. This structure can meet the requirements for muck removal while supporting the weight of the reamed shaft boring machine, allowing the machine to advance all the way to the bottom of the lower tunnel 10.

[0082] After the shaft excavation is completed, the tunneling machine can be dismantled. The dismantling process is essentially the reverse of the installation process. The following describes a method for dismantling a shaft tunneling machine, which is the aforementioned type of machine. The dismantling method includes the following steps:

[0083] 1b. First, disconnect the connection between the main machine system 101 and the downstream supporting system. After disconnecting the connecting pipeline between the main machine system 101 and the downstream supporting system, use the hoisting ground beam system 3 to move the hoisting platform assembly 102 of the reaming shaft boring machine 1 upwards until the lower end of the hoisting platform assembly 102 is higher than the lower end of the downstream supporting installation section 702. The position of the lower end of the hoisting platform assembly 102 should ensure that the hoisting platform assembly support beam 5 can be installed smoothly in step 2b below. Figure 1 As shown. In this step, the hoisting ground beam system 3 does not move the main system 101 upward. At this time, part or all of the main system 101 is located in the lower roadway 10.

[0084] 2b. Install the lifting platform support beam 5 at the lower end of the rear supporting installation section 702. The end of the lifting platform support beam 5 is inserted into the first crossbeam installation groove 703 of the starting shaft 7. The lifting platform support beam 5 is in a horizontal state. The lifting platform 102 is placed on the lifting platform support beam 5 by using the lifting ground beam system 3.

[0085] 3b. Remove the hoisting ground beam system 3. The hoisting ground beam system 3 is disassembled into its constituent components. The hoisting ground beam system 3 can no longer block the wellhead of the launching well 7.

[0086] 4b. Remove the transfer support plate 602 using the hoisting top beam system 2. Inside the launching shaft 7, disassemble the transfer support plate 602 into its components, and the hoisting top beam system 2 lifts out the components of the transfer support plate 602.

[0087] 5b. Remove the turntable support beam 601 and use the hoisting top beam system 2 to lift the turntable support beam 601 out.

[0088] 6b. Using the hoisting top beam system 2, dismantle each layer of the hoisting platform assembly 102, breaking down the hoisting platform assembly 102 and the subsequent supporting system into components. The hoisting top beam system 2 then lifts out the intermediate support plate 602 and the components of the subsequent supporting system, such as... Figure 1 As shown.

[0089] 7b. Remove the support beam 5 of the suspended platform assembly and use the lifting top beam system 2 to lift the support beam 5 of the suspended platform assembly out.

[0090] 8b. Using the hoisting top beam system 2, dismantle the enlarged shaft tunneling machine 1. Disassemble the enlarged shaft tunneling machine 1 into its components within the lower roadway 10. The hoisting top beam system 2 then lifts out the components of the enlarged shaft tunneling machine 1. The lifted-out components of the shaft tunneling machine can be placed inside the chamber 8. At this point, the dismantling of the shaft tunneling machine is complete.

[0091] The steps in the disassembly method of the shaft tunneling machine are in the following order: 1b, 2b, 3b, 4b, 5b, 6b, 7b, 8b.

[0092] The above description is merely a specific embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any substitution of equivalent components or equivalent changes and modifications made within the scope of protection of this patent should still fall within the scope of this patent. Furthermore, the technical features, technical solutions, and embodiments of the present invention can be freely combined and used together.
