Description

Technical Field

[0001] This application relates to the field of shaft construction, and in particular to a functional layout structure inside an ultra-deep vertical shaft of a railway tunnel. Background Technology

[0002] A shaft is a vertical tunnel excavated above a tunnel and connected to it. Shaft excavation is typically carried out during the construction of mines or long tunnels. After the shaft is excavated, the site inside the shaft is usually arranged to meet the functional requirements of the shaft, such as power supply, concrete production, equipment maintenance, component processing, and wastewater treatment.

[0003] Specifically, after excavation of the shaft, a site layout structure is typically excavated at the bottom of the shaft to facilitate rapid overall tunnel construction. This site layout structure usually includes the main tunnel, pilot tunnel, narrow passageway, and muck transfer yard. The main tunnel and pilot tunnel are arranged parallel to each other, connected by a passageway. The narrow passageway is located at the bottom of the shaft. Two muck transfer yards are located on either side of the narrow passageway, with the ends of the two transfer yards furthest from the narrow passageway connected to the pilot tunnel. During construction, excavated muck and rock are transported from the pilot tunnel and main tunnel to the muck transfer yard for temporary storage using stone transport vehicles. The muck and rock from the transfer yard are then moved to the bottom of the shaft using buckets and subsequently hoisted out of the shaft.

[0004] To ensure the ventilation performance of the site layout structure, ventilation modules are usually required. The ventilation module includes a fan and a ventilation duct. One end of the ventilation duct is connected to the outside of the shaft, and the other end is connected to the working face. The fan is usually installed in the ventilation duct and is set in the shaft. The ventilation duct sends air to the working face of the pilot tunnel and the main tunnel through the slag transfer yard. During the ventilation process, the dust in the slag transfer yard can easily affect the ventilation duct, making it difficult to ensure the ventilation performance of the ventilation duct. Utility Model Content

[0005] In order to prevent dust in the ballast yard from affecting the ventilation ducts and thus ensure the ventilation performance of the ventilation ducts, this application provides a functional layout structure inside the shaft of an ultra-deep vertical shaft in a railway tunnel.

[0006] The technical solution provided in this application for a functional layout structure within an ultra-deep vertical shaft of a railway tunnel is as follows:

[0007] A functional layout structure for an ultra-deep vertical shaft in a railway tunnel includes a main tunnel and a pilot tunnel, as well as a main narrow space. The main narrow space is located at the bottom of the main shaft. The main tunnel and the pilot tunnel are arranged parallel to each other, and a connecting channel connects the main tunnel and the pilot tunnel. The structure also includes an auxiliary shaft and a ventilation space. Both the auxiliary shaft and the ventilation space are located on the side of the main tunnel away from the pilot tunnel. One end of the ventilation space is connected to the auxiliary shaft, and the other end is connected to the main tunnel. The ventilation space is equipped with a ventilation module, which includes a fan and four ventilation ducts. One end of each ventilation duct leads to the ground through the auxiliary shaft, and the other end leads to the working faces of the pilot tunnel and the main tunnel, respectively. The fan is connected to and installed in each ventilation duct and is located within the ventilation space.

[0008] By adopting the above technical solution, during the ventilation process of the ventilation ducts to the working faces of the horizontal guide tunnel and the main tunnel, the fans and ventilation ducts are isolated from the slag transfer site. This makes it less likely for dust in the slag transfer site to affect the ventilation ducts, which helps to ensure the ventilation performance of the ventilation ducts. In addition, the setting of the auxiliary shaft facilitates the use of the auxiliary shaft as an additional transportation channel to transport personnel, materials, equipment, etc., ensuring the timely supply of resources required for construction and further ensuring construction efficiency.

[0009] Optionally, two ventilation channels are provided between the main tunnel and the horizontal guide, wherein the two ventilation pipes respectively pass through the two ventilation channels into the horizontal guide.

[0010] By adopting the above technical solution, the ventilation channel provides a dedicated channel for ventilation of the two working faces of the pilot tunnel and the main tunnel, which helps to further reduce the impact of dust during tunnel construction and better ensure the ventilation performance of the ventilation duct.

[0011] Optionally, it also includes a secondary narrow space and a material transfer area, wherein the secondary narrow space is located at the bottom of the secondary shaft, the material transfer area is connected to one end of the secondary narrow space, and the end of the material transfer area away from the secondary narrow space is connected to the main tunnel.

[0012] By adopting the above technical solutions, the setting up of the material transfer yard further increases the storage space, making it easier to store a larger quantity of excavated soil and rock generated during tunnel excavation.

[0013] Optionally, it also includes a fixing mechanism for fixing the ventilation duct. Multiple fixing mechanisms are distributed along the length of the ventilation duct. The fixing mechanism includes a fixing base and a fixing mounting seat. The fixing mounting seat is installed on the fixing base. The top of the fixing mounting seat has an installation groove for placing the ventilation duct. Two fixing plates are arranged opposite each other in the installation groove. The fixing mounting seat is provided with a fixing drive assembly for driving the two fixing plates to move toward each other or away from each other.

[0014] By adopting the above technical solution, when the ventilation duct is placed in the installation groove, the two fixing plates are driven to move towards each other by the fixed drive assembly, which facilitates the clamping and fixing of the ventilation duct, thereby ensuring the stability of the ventilation duct's position.

[0015] Optionally, the fixed drive assembly includes two fixed lead screws and two fixed guide rods. The two fixed lead screws are rotatably mounted on the opposite side of the two fixed plates. Both fixed lead screws pass through the fixed mounting base and are threaded into the fixed mounting base. The two fixed guide rods are fixedly mounted on the opposite side of the two fixed plates. Both fixed guide rods pass through the fixed mounting base and slide into the fixed mounting base.

[0016] By adopting the above technical solution, when one of the fixed screws is rotated, the fixed plate moves towards or away from the other fixed plate under the limiting action of the fixed guide rod. The setting that the two fixed screws drive the two fixed plates to move respectively makes it easy for the fixed mounting base to achieve stable fixation of both sides of the ventilation duct at different positions. It has strong applicability, and when fixing the ventilation duct at different positions, it can achieve stable fixation of the ventilation duct according to the location of the ventilation duct, which is conducive to ensuring the performance of the ventilation duct.

[0017] Optionally, the two fixing plates are arranged in an arc shape on the side that is close to each other.

[0018] By adopting the above technical solution, the arc-shaped surfaces of the two fixing plates further fix the position of the ventilation duct when it is fixed, which helps to further ensure the stability of the position of the ventilation duct when it is fixed.

[0019] Optionally, the fixed base is provided with a lifting assembly, which includes a lifting screw, a lifting worm gear, a lifting worm, a lifting motor, and a lifting limiter. The lifting screw is fixedly installed at the bottom of the fixed mounting base, passes through the lifting worm gear, and is threadedly engaged with the lifting worm gear. The top of the fixed base has a movable groove for accommodating the lifting screw. The lifting worm gear is coaxially and rotatably installed on the fixed base, and the lifting worm is rotatably installed on the fixed base and meshes with the lifting worm gear. The lifting motor is used to drive the lifting worm to rotate, and the lifting limiter is used to restrict the rotation of the lifting screw around its own axis.

[0020] By adopting the above technical solution, when the lifting motor drives the lifting worm gear to rotate, the lifting worm wheel rotates together. The lifting screw moves vertically due to its threaded engagement with the lifting worm wheel and the limiting action of the lifting limit device, thereby realizing the lifting and lowering of the fixed mounting base. This makes it easy for the fixed mounting base to fix the ventilation duct at different heights, and it has strong applicability.

[0021] Optionally, a fixed base plate is fixedly installed at the bottom of the fixed base, and the fixed base plate is fixed to the bottom of the well by anchor bolts. The lifting limit component includes a limit strip fixedly installed on the wall of the movable groove. A limit groove extending along its own axis is opened on the outer side of the lifting screw. The limit groove extends to the bottom of the lifting screw, and the limit strip slides and engages in the limit groove.

[0022] By adopting the above technical solution, the fixed base plate facilitates the stable fixing of the fixed base to the bottom of the well, thereby ensuring the stability of the fixed base position. The setting of the limit strip and limit groove makes the structure that restricts the lifting screw from rotating around its own axis simple, convenient and stable.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During the ventilation process of the ventilation ducts to the working faces of the horizontal guide tunnel and the main tunnel, the fans and ventilation ducts are isolated from the slag transfer site, so that the dust in the slag transfer site is less likely to affect the ventilation ducts, which helps to ensure the ventilation performance of the ventilation ducts.

[0025] 2. The ventilation duct provides a dedicated channel for ventilation of the two working faces of the pilot tunnel and the main tunnel, which helps to further reduce the impact of dust during tunnel construction and better ensures the ventilation performance of the ventilation duct.

[0026] 3. When the ventilation duct is placed in the installation groove, the two fixing plates are driven to move towards each other by the fixed drive assembly, which facilitates the clamping and fixing of the ventilation duct, thereby ensuring the stability of the ventilation duct's position.

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] This application discloses a functional layout structure within an ultra-deep vertical shaft of a railway tunnel. (Refer to...) Figure 1 The functional layout structure inside the ultra-deep vertical shaft of the railway tunnel includes a main shaft 1, a main tunnel 2, a pilot tunnel 3, a main narrow space 4, and a muck transfer yard 5. The main narrow space 4 is located at the bottom of the main shaft 1. There are two muck transfer yards 5, located on both sides of the narrow space. The ends of the two muck transfer yards 5 away from the narrow space are connected to the pilot tunnel 3. The main tunnel 2 and the pilot tunnel 3 are arranged in parallel. A connecting passage 6 is provided between the main tunnel 2 and the pilot tunnel 3. During the construction process, the excavated soil and rock are transported from the pilot tunnel 3 and the main tunnel 2 to the muck transfer yard 5 for temporary storage by stone transport vehicles. Then, the soil and rock in the muck transfer yard 5 are moved to the bottom of the main shaft 1 in the main narrow space 4 by buckets and then hoisted out of the shaft.

[0034] Continue to refer to Figure 1 Furthermore, the functional layout structure inside the ultra-deep vertical shaft of the railway tunnel also includes a secondary shaft 7, a ventilation space 8, a secondary narrow space 9, a material transfer yard 10, and a fixing mechanism. The secondary shaft 7 and the ventilation space 8 are both located on the side of the main tunnel 2 away from the pilot tunnel 3. The secondary narrow space 9 is located at the bottom of the secondary shaft 7. The material transfer yard 10 is connected to one end of the secondary narrow space 9, and the end of the material transfer yard 10 away from the secondary narrow space 9 is connected to the main tunnel 2 to further increase the storage space and facilitate the storage of a larger quantity of soil and rock generated during the tunnel excavation process.

[0035] Continue to refer to Figure 1The ventilation space 8 is connected to the auxiliary shaft 7 at one end and to the main tunnel 2 at the other end. The ventilation space 8 is equipped with a ventilation module, which includes a fan 11 and ventilation ducts 12. There are four ventilation ducts 12. One end of each ventilation duct 12 is connected to the ground through the auxiliary shaft 7, and the other end is connected to the working faces of the guide tunnel 3 and the main tunnel 2 respectively. The fan 11 is connected to each ventilation duct 12 and is located in the ventilation space 8, so that the dust in the slag transfer yard 5 and the material transfer yard 10 will not easily affect the ventilation ducts 12, which is conducive to ensuring the ventilation performance of the ventilation ducts 12.

[0036] Continue to refer to Figure 1 In addition, two ventilation channels 13 are connected between the main tunnel 2 and the pilot tunnel 3. Two ventilation pipes 12 pass through the two ventilation channels 13 to the pilot tunnel 3, so that the ventilation pipes 12 have dedicated channels for ventilating the pilot tunnel 3 and the two working faces of the main tunnel 2, which helps to further reduce the impact of dust during tunnel construction.

[0037] Reference Figure 2 Multiple fixing mechanisms are distributed along the length of the ventilation duct 12. The fixing mechanism includes a fixing base 14 and a fixing mounting base 15. The fixing base 14 has a fixing base plate 16 fixedly installed at its bottom. The fixing base plate 16 is fixed to the bottom of the well by anchor bolts 17 distributed around its own axis to ensure the stability of the position of the fixing base 14.

[0038] Reference Figure 2 and Figure 3 The fixed base 14 is equipped with a lifting assembly, which includes a lifting screw 18, a lifting worm gear 19, a lifting worm 20, a lifting motor 21, and a lifting limit component. The top of the fixed base 14 has a movable slot 22 for accommodating the lifting screw 18. The lifting screw 18 is fixedly installed at the bottom of the fixed mounting base 15. The lifting screw 18 passes through the lifting worm gear 19 and is threadedly engaged with it. The lifting worm gear 19 is coaxially and rotatably mounted on the top of the fixed base 14. The lifting worm 20 is rotatably mounted on the fixed base 14 and meshes with the lifting worm gear 19. The lifting motor 21 is mounted on the fixed base 14 and drives the lifting worm 20 to rotate.

[0039] Continue to refer to Figure 2 and Figure 3The lifting limit component includes a limit strip 23 fixedly installed on the wall of the movable groove 22. A limit groove 24 extending along its own axis is opened on the outer side of the lifting screw 18. The limit groove 24 extends to the bottom of the lifting screw 18. The limit strip 23 slides and fits in the limit groove 24 so that when the lifting motor 21 drives the lifting worm gear to rotate, the lifting worm wheel 19 rotates together. The lifting screw 18 moves vertically due to the threaded engagement with the lifting worm wheel 19 and the limiting action of the lifting limit strip 23 and the lifting limit groove 24, thereby realizing the lifting and lowering of the fixed mounting base 15. This facilitates the fixing of the ventilation duct 12 at different height positions of the fixed mounting base 15, making it highly applicable.

[0040] Reference Figure 2 The top of the fixed mounting base 15 has a mounting groove 25, which extends along the length of the ventilation duct 12 to both sides of the fixed mounting base 15, so that the mounting groove 25 can be used to place the ventilation duct 12. Two fixing plates 26 are arranged opposite each other in the mounting groove 25, and the two fixing plates 26 are respectively located on both sides of the ventilation duct 12. The fixed mounting base 15 is provided with a fixed drive assembly that drives the two fixing plates 26 to move towards or away from each other.

[0041] Reference Figure 2 and Figure 3 Specifically, the fixed drive assembly includes two fixed lead screws 27 and two fixed guide rods 28. The two fixed lead screws 27 are rotatably mounted on the opposite sides of the two fixed plates 26. Both fixed lead screws 27 pass through the fixed mounting base 15 and are threaded into the fixed mounting base 15. The two fixed guide rods 28 are fixedly mounted on the opposite sides of the two fixed plates 26. Both fixed guide rods 28 pass through the fixed mounting base 15 and are slidably engaged with the fixed mounting base 15. This allows the fixed plate 26 to move towards or away from the other fixed plate 26 under the limiting action of the fixed guide rod 28 when one of the fixed lead screws 27 is rotated. The arrangement of the two fixed lead screws 27 driving the movement of the two fixed plates 26 respectively facilitates the fixed mounting base 15 to achieve stable fixation of both sides of the ventilation duct 12 at different positions.

[0042] Continue to refer to Figure 2 and Figure 3 To further ensure the stability of the fixing plate 26 when clamping and fixing the ventilation duct 12, the two fixing plates 26 are arranged in an arc shape on the side that is close to each other. In order to facilitate the application of force to rotate the fixing screw 27, a fixing handle 29 is fixedly connected to one end of the two fixing screws 27 that passes through the fixing mounting base 15.

[0043] The implementation principle of the functional layout structure inside the ultra-deep vertical shaft of a railway tunnel according to the embodiments of this application is as follows: During the ventilation process of the ventilation duct 12 to the two working faces of the horizontal guide 3 and the main tunnel 2, the fan 11 and the ventilation duct 12 are isolated from the ballast transfer yard 5 and the material transfer yard 10, so that the dust in the ballast transfer yard 5 and the material transfer yard 10 is not likely to affect the ventilation duct 12, which is conducive to ensuring the ventilation performance of the ventilation duct 12. In addition, the setting of the auxiliary shaft 7 makes it easy to use the auxiliary shaft 7 as an additional transportation channel to transport personnel, equipment, etc., to ensure the timely supply of resources required for construction, which is conducive to further ensuring construction efficiency. Furthermore, the clamping effect of the two fixing plates 26 of the fixing mechanism on the ventilation duct 12 is conducive to fully ensuring the stability of the position of the ventilation duct 12.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
