Description

Technical Field

[0001] This application relates to the field of tunnel boring technology, and more specifically, to an in-situ starting construction process and an in-situ starting device. Background Technology

[0002] When a tunnel boring machine (TBM) advances, it uses support shoes inside the shield to support the hard rock walls of the tunnel, providing reaction force for the TBM's propulsion cylinders. At the start of the tunneling process, because the shield cannot yet enter the tunnel and cannot support the hard rock walls, the support shoes cannot provide reaction force for the TBM's propulsion cylinders. To address this issue, the current solution primarily involves using a drill-and-blast method to excavate a section, forming an assembly chamber and a circular starting chamber. After the TBM is assembled in the assembly chamber, it then moves into the starting chamber to begin construction. However, because the space in the assembly chamber does not meet the starting requirements, the TBM cannot directly begin construction from within the assembly chamber.

[0003] The aforementioned initial construction method requires the excavation of a relatively long starting chamber, which not only results in a significant loss of manpower and resources but also greatly prolongs the construction period. Furthermore, the safety risks associated with drilling and blasting or mechanical excavation of long tunnel paths are substantial. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] When a tunnel boring machine (TBM) advances, it uses support shoes inside the shield to support the hard rock walls of the tunnel, providing reaction force for the TBM's propulsion cylinders. At the start of the tunneling process, because the shield cannot yet enter the tunnel and cannot support the hard rock walls, the support shoes cannot provide reaction force for the TBM's propulsion cylinders. To address this issue, the current solution primarily involves using a drill-and-blast method to excavate a section, forming an assembly chamber and a circular starting chamber. After the TBM is assembled in the assembly chamber, it then moves into the starting chamber to begin construction. However, because the space in the assembly chamber does not meet the starting requirements, the TBM cannot directly begin construction within the assembly chamber.

[0034] The aforementioned initial construction method requires the excavation of a relatively long starting chamber, which not only results in a significant loss of manpower and resources but also greatly prolongs the construction period. Furthermore, the safety risks associated with drilling and blasting or mechanical excavation of long tunnel paths are substantial.

[0035] To address the aforementioned technical problems, embodiments of this application provide an in-situ launching process and an in-situ launching process.

[0036] The on-site starting construction process provided in this application includes:

[0037] Reference Figure 1 , Figure 2 As shown, a tunneling machine track 101 extending to the tunneling construction area is laid at the bottom of the assembly chamber 100 in advance; and support fixtures 102 are installed on the side walls of the assembly chamber 100 on both sides of the tunneling machine track 101.

[0038] Reference Figure 3 As shown, after the tunnel boring machine 103 is assembled on the tunnel boring machine track 101, the support shoe of the tunnel boring machine 103 supports the side wall of the assembly chamber 100 through the support fixture 102, generating a reaction force on the tunnel boring machine 103, so that the tunnel boring machine 103 can advance towards the construction area on the tunnel boring machine track 101.

[0039] After the tunnel boring machine 103 stops advancing, the tunnel boring machine 103 retracts its support shoe; the support fixture 102 is driven to move a preset distance along the advancing direction 104, and the support shoe extends again and supports the side wall of the assembly chamber 100 through the support fixture 102 to achieve secondary advancement;

[0040] Repeat the two-stage advancing action until the tunnel boring machine 103 enters the construction area.

[0041] Specifically, refer to Figure 2 As shown, the support fixture 102 includes a first tensioning fixture 107 and a second tensioning fixture 108 located on both sides of the tunnel boring machine 103.

[0042] The support shoes on both sides of the tunnel boring machine 103 can be connected to the support parts of the first tensioning fixture 107 and the second tensioning fixture 108, respectively. At the start, the propulsion cylinder 115 on the support shoe extends and abuts against the support parts of the first tensioning fixture 107 and the second tensioning fixture 108. The first tensioning fixture 107 and the second tensioning fixture 108 abut against the side wall of the assembly chamber 100, generating a reaction force on the support shoe to make the tunnel boring machine 103 move forward.

[0043] It should be noted that after the first tensioning fixture 107 and the second tensioning fixture 108 come into contact with the assembly chamber 100, the propulsion cylinder 115 extends, causing the tunnel boring machine 103's shield to advance forward until the propulsion cylinder 115 extends to its maximum length, completing one advance. After the first tensioning fixture 107 and the second tensioning fixture 108 release their contact force with the side wall of the installation chamber, the propulsion cylinder 115 shortens, causing the support shoe to retract, while simultaneously driving the first tensioning fixture 107 and the second tensioning fixture 108 closer to the shield. Then, the above steps are repeated until the propulsion cylinder 115 of the entire tunnel boring machine 103 can directly abut against both sides of the tunnel, at which point the in-situ launching device provided in this embodiment is removed.

[0044] It should be noted that the tunnel boring machine 103 can be directly assembled on the tunnel boring machine track 101 inside the assembly chamber 100. After assembly, the above method can be used to achieve on-site starting.

[0045] Compared with the prior art, the construction process provided in this application embodiment can help the tunnel boring machine 103 to start directly in the assembly chamber 100 without the need to excavate additional chambers, effectively reducing construction costs, shortening the construction period, and reducing construction risks to a certain extent.

[0046] As an optional implementation, before the support shoe of the tunnel boring machine 103 is used to support the side wall of the assembly chamber 100 through the support fixture 102, the side wall of the assembly chamber 100 is first reinforced.

[0047] Specifically, refer to Figure 1 , Figure 2 as well as Figure 3 As shown, a tunnel boring machine track 101 extending to the tunneling construction area is laid at the bottom of the assembly chamber 100; and after support fixtures 102 are installed on the side walls of the assembly chamber 100 on both sides of the tunnel boring machine track 101, a lateral reinforcement structure 106 is also installed on the side walls of the assembly chamber 100. The support fixtures 102 abut against the lateral reinforcement structure 106 on the side facing away from the tunnel boring machine 103.

[0048] The purpose of this application embodiment is to improve the robustness of the side wall structure of the assembly chamber 100, strengthen the side wall of the assembly chamber 100, prevent damage to the side wall of the assembly chamber 100 when the tunnel boring machine 103 starts, and enhance the safety and reliability of starting in place.

[0049] It should be noted that the lateral reinforcement structure 106 can be a lateral support track, and the extension path of the lateral support track is consistent with that of the support track.

[0050] In this embodiment, the lateral support rails are extended on both sides of the tunnel boring machine 103 to ensure that the support fixture 102 and the rock wall of the assembly chamber 100 have a large contact surface. By increasing the contact surface, stable and reliable support is provided for the first tensioning fixture 107 and the second tensioning fixture 108.

[0051] It should be noted that, referring to Figure 2 As shown, the first clamping fixture 107 and the second clamping fixture 108 generate friction after abutting against the side wall of the assembly chamber 100. During initial propulsion, the propulsion cylinder 115 on the support shoe of the tunnel boring machine 103 exerts a rearward thrust on the first clamping fixture 107 and the second clamping fixture 108. The friction generated by the first clamping fixture 107 and the second clamping fixture 108 abutting against the side wall of the assembly chamber needs to balance the rearward thrust of the support shoe to ensure that the first clamping fixture 107 and the second clamping fixture 108 remain in their original positions, thus providing stable support for the propulsion cylinder 115.

[0052] To implement the above process, refer to Figure 1 , Figure 2 as well as Figure 3 As shown, this application embodiment provides an in-situ launching device, which includes a support fixture 102 and a tunneling machine track 101; the tunneling machine track 101 is laid at the bottom of the assembly chamber 100 and extends to the tunneling construction area; the support fixture 102 is arranged on both sides of the tunneling machine track 101 and abuts against the side wall of the assembly chamber 100, and the support fixture 102 can move along the side wall of the assembly chamber 100.

[0053] Specifically, the bottom surface of the assembly chamber 100 is provided with a horizontal support rail 105 for supporting the movement of the tooling 102; the extension path of the horizontal support rail 105 is consistent with the tunneling machine rail 101, and the bottom of the tooling 102 is slidably connected to the horizontal support rail 105.

[0054] It should be noted that both the first tensioning fixture 107 and the second tensioning fixture 108 have support parts for contacting the support shoes of the tunnel boring machine 103 and generating support force. Compared with the prior art, the in-situ launching device provided in this application embodiment can help the tunnel boring machine 103 to directly launch in the assembly chamber 100 without having to excavate a new launching chamber, effectively reducing construction costs, shortening the construction period, and reducing construction risks to a certain extent.

[0055] It should be noted that the extension path of the horizontal support rail 105 is consistent with that of the tunneling machine rail 101, and the bottom of the support fixture 102 is slidably connected to the horizontal support rail 105. This embodiment effectively reduces the friction between the support fixture 102 and the floor of the assembly chamber 100 through the above-mentioned arrangement. The support fixture 102 slides on the floor of the assembly chamber 100 via the horizontal support rail 105, which facilitates the step-changing propulsion of the support fixture 102, shortens the step-changing time, and increases the propulsion speed for starting from the spot.

[0056] It should be noted that both the lateral support rail and the horizontal support rail 105 in this embodiment are steel rails. For example, I-beam steel rails can be used, and the specific rail type can be selected by those skilled in the art as needed.

[0057] It should be noted that after one advancement is completed in this embodiment, the retraction of the support shoe will cause the first tensioning fixture 107 and the second tensioning fixture 108 to move on the horizontal support track 105. At this time, since the support shoe does not apply a pushing force to the support fixture 102, the friction between the support fixture 102 and the side wall of the assembly chamber 100 is greatly reduced, and the retraction of the support shoe generates a pulling force that drives the support fixture 102 forward.

[0058] It should be noted that the propulsion cylinders 115 on both support shoes have a V-shaped structure, with the larger V-shaped opening facing the opposite direction of propulsion. Therefore, in this embodiment, the support fixture 102 can abut against the assembly chamber 100 during propulsion, generating a sufficient reaction force to push the tunnel boring machine 103 forward. During step change, the V-shaped opening of the propulsion cylinder 115 narrows, so that the support fixture 102 is not hindered by the friction of the side wall of the assembly chamber 100. Combined with the design of the horizontal support rail 105, it is ensured that the support fixture 102 can move forward when the support shoes retract. It should also be noted that the friction generated by the movement of the tunnel boring machine 103 is greater than the friction generated by the movement of the support fixture 102. Therefore, there is no need to worry about the tunnel boring machine 103 moving backward when the support shoes retract and a step change occurs.

[0059] Reference Figure 4 As shown, in one alternative implementation, the bottom of the support fixture 102 is provided with a rail clamp 114 for clamping the horizontal support rail 105 so that the support fixture 102 is fixed to the horizontal support rail 105.

[0060] Furthermore, in this embodiment, a rail clamp 114 is also provided on the support fixture 102. It should be noted that when the support fixture 102 abuts against the support shoe in this embodiment, the rail clamp 114 locks the support fixture 102 to fix it to the horizontal support rail 105, which helps to increase the stability of the support fixture 102, facilitates the enhancement of the reaction force acting on the tunnel boring machine 103, and ensures that the tunnel boring machine 103 can advance rapidly.

[0061] When changing steps, before the support shoe retracts, the rail clamp 114 is unlocked, allowing the support fixture 102 to move smoothly on the horizontal support rail 105.

[0062] Reference Figure 2 As shown, as an alternative implementation, the support fixture 102 includes a first tensioning fixture 107 and a second tensioning fixture 108 respectively disposed on both sides of the tunnel boring machine 103.

[0063] The tunnel boring machine 103 has abutment surfaces on both sides; a first support shoe box 109 is provided on the first tensioning fixture 107, and the first support shoe box 109 abuts against the abutment surface on the first side of the tunnel boring machine 103; a second support shoe box 110 is provided on the second tensioning fixture 108, and the second support shoe box 110 abuts against the abutment surface on the second side of the tunnel boring machine 103.

[0064] Reference Figure 3 , Figure 4 As shown, the first support shoe box 109 has a first support box 111 on the side away from the tunnel boring machine 103, which abuts against the inner wall of the assembly chamber 100; a first telescopic adjustment member 112 is provided between the first support box 111 and the first support shoe box 109; and / or, the second support shoe box 110 has a second support box on the side away from the tunnel boring machine 103, which abuts against the inner wall of the assembly chamber 100; a second telescopic adjustment member is provided between the second support box and the second support shoe box 110.

[0065] It should be noted that, in this embodiment of the application, a first support shoe box 109 is provided on the first tensioning fixture 107, and a second support shoe box 110 is provided on the second tensioning fixture 108. The first support shoe box 109 and the second support shoe box 110 clamp the tunnel boring machine 103 from both sides, which can adjust the attitude and position of the tunnel boring machine 103, so that the tunnel boring machine 103 has a stable body attitude during the initial operation.

[0066] Specifically, the first tensioning fixture 107 can drive the first support shoe box 109 to move closer to or away from the tunnel boring machine 103 via the first telescopic adjustment member 112; the second tensioning fixture 108 can drive the second support shoe box 110 to move closer to or away from the tunnel boring machine 103 via the second telescopic adjustment member. Therefore, the embodiments of this application can realize the adjustment of the left and right posture of the tunnel boring machine 103.

[0067] As an alternative implementation, both the first support shoe box 109 and the second support shoe box 110 are filled with counterweight particles; both the first support shoe box 109 and the second support shoe box 110 are provided with valves 113 at their bottoms. When the valves 113 are opened, the counterweight particles are discharged under the action of gravity.

[0068] The embodiment of this application uses counterweight particles to increase the mass of the first support shoe box 109 and the second support shoe box 110, which helps to improve the stability of the entire device.

[0069] The counterweight particles can be iron sand, metal particles, or other particulate matter. This application does not impose specific limitations on the type of counterweight particles used in its embodiments; those skilled in the art can select the appropriate type as needed.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
