Superconducting electric maglev trains have advantages such as high speed, low energy consumption, environmental friendliness, and high safety, and are considered an important development direction for future intercity high-speed transportation. Currently, some countries have conducted research and testing on superconducting electric maglev train technology and have made some progress. With continuous technological advancements and cost reductions, superconducting electric maglev trains are expected to become one of the main modes of transportation for intercity high-speed travel in the future.

[0003] Currently, existing superconducting maglev track structures are mainly constructed using cast-in-place methods, resulting in a large volume of concrete being poured on-site. Furthermore, the traction coils and suspension guide coils cannot be installed precisely and quickly on-site, all of which reduce construction efficiency. Summary of the Invention

[0004] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention provides a prefabricated superconducting maglev track structure and its construction method.

[0010] Optionally, the prefabricated superconducting maglev track structure further includes a lower foundation and two spaced adjustment layers, each of which is located between the lower foundation and the inverted T-shaped track and is a cast-in-place concrete structure.

[0011] Optionally, each of the adjustment layers is fitted with a plurality of spaced second anchor bolts. One end of the second anchor bolt is inserted into the adjustment layer, and the other end of the second anchor bolt passes through the bottom of the inverted T-shaped track. The other end of the second anchor bolt is fitted with a second anchor nut to fix the bottom of the inverted T-shaped track onto the adjustment layer.

[0012] Optionally, each of the inverted T-shaped rails has a through hole at its bottom, the diameter of which is larger than the diameter of the second anchor bolt. An adjusting ring is detachably inserted into the gap between the through hole and the second anchor bolt to adjust the position of the inverted T-shaped rail laterally. The second anchor nut abuts against the top of the adjusting ring.

[0013] Optionally, the bottom of the second anchor bolt abuts against the lower foundation, and a second positioning nut is fitted on the second anchor bolt. The second positioning nut is located below the bottom of the inverted T-shaped track to clamp the bottom of the inverted T-shaped track.

[0014] Optionally, a washer is fitted on the other end of the second anchor bolt, and the washer is sandwiched between the second anchor nut and the bottom of the inverted T-shaped track.

[0015] Optionally, a portal steel bar is inserted into the bottom of each of the inverted T-shaped tracks to fix the inverted T-shaped tracks.

[0016] In a second aspect, the present invention provides a construction method for a prefabricated superconducting maglev track structure, the construction method being based on the prefabricated superconducting maglev track structure described in the first aspect, the construction method comprising:

[0017] Prefabricate the inverted T-shaped track and the connecting frame;

[0018] According to the design requirements, two inverted T-shaped tracks are laid at intervals, and the connecting frame is laid between the two inverted T-shaped tracks;

[0019] Adjust the lateral spacing between the two inverted T-shaped tracks, and pour the post-cast strip between both ends of the connecting frame and the corresponding inverted T-shaped tracks;

[0021] After inserting the other end of the first anchor bolt into the corresponding adjustment hole and adjusting it to the correct position, it is then filled with anchoring agent and anchored in the corresponding adjustment hole.

[0022] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0023] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include:

[0024] For the prefabricated superconducting maglev track structure provided in this embodiment of the invention, during construction, firstly, inverted T-shaped tracks and connecting frames are prefabricated, thereby reducing the amount of concrete poured on-site and improving construction efficiency. Next, according to design requirements, two inverted T-shaped tracks are laid at intervals, and a connecting frame is laid between the two inverted T-shaped tracks. Post-cast strips are poured at both ends of the connecting frame and between the corresponding inverted T-shaped tracks, thus making the two inverted T-shaped tracks form a whole, resulting in better track accuracy during use.

[0025] Then, the levitation guide coil or traction coil is fixed to one end of the corresponding first anchor bolt, thus connecting the coil and the first anchor bolt. Finally, the other end of the first anchor bolt is inserted into the corresponding adjustment hole and moved and adjusted into place. After filling with anchoring agent, it is anchored in the corresponding adjustment hole. Since the inverted T-shaped track will have certain errors during prefabrication and installation, the position of the first anchor bolt and the corresponding coil is precisely adjusted by moving the first anchor bolt laterally or longitudinally in the larger adjustment hole. After adjustment, it is filled and fixed with anchoring agent, thus quickly and accurately fixing the levitation guide coil or traction coil, further ensuring construction efficiency.

[0026] In other words, the prefabricated superconducting maglev track structure provided by the embodiments of the present invention can not only reduce the concrete pouring on the construction site, but also ensure the integrity and accuracy of the two inverted T-shaped tracks, and can quickly and accurately fix the suspension guide coil or traction coil, thereby improving construction efficiency.

[0041] Example:

[0042] Figure 1 This is a structural schematic diagram of a prefabricated superconducting magnetic levitation track structure provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the prefabricated superconducting maglev track structure includes two inverted T-shaped tracks 1 and a connecting frame 2.

[0043] Figure 2 This is a cross-sectional view of the inverted T-shaped track 1 provided in an embodiment of the present invention, as shown below. Figure 2 As shown, two inverted T-shaped tracks 1 are arranged laterally and symmetrically. Each inverted T-shaped track 1 has a first groove 11 and a second groove 12 that are connected to each other on one side facing the corresponding inverted T-shaped track 1. The first groove 11 is located outside the second groove 12. A suspension guide coil 13 is inserted into the first groove 11, and a traction coil 14 is inserted into the second groove 12. Each inverted T-shaped track 1 has a plurality of spaced adjustment holes 15. Each adjustment hole 15 is connected to the first groove 11 or the second groove 12. A first anchor bolt 16 is inserted into each adjustment hole 15. The suspension guide coil 13 or the traction coil 14 is fixed to one end of the corresponding first anchor bolt 16. The first anchor bolt 16 is configured such that after the other end of the first anchor bolt 16 is inserted into the corresponding adjustment hole 15 and moved to the position, it is anchored in the corresponding adjustment hole 15 after being filled with anchoring agent.

[0044] Both the connecting frame 2 and each inverted T-shaped track 1 are prefabricated structural components. The top of the connecting frame 2 has two spaced wheel running surfaces 21. The connecting frame 2 is located between the two inverted T-shaped tracks 1, and both ends of the connecting frame 2 are connected to the corresponding inverted T-shaped tracks 1 by post-pouring strips 22.

[0045] For the prefabricated superconducting maglev track structure provided in this embodiment of the invention, during construction, firstly, the inverted T-shaped track 1 and connecting frame 2 are prefabricated, thereby reducing the amount of concrete poured on site and improving construction efficiency. Next, according to design requirements, two inverted T-shaped tracks 1 are laid at intervals, and the connecting frame 2 is laid between the two inverted T-shaped tracks 1. Post-cast strips 22 are poured at both ends of the connecting frame 2 and between the corresponding inverted T-shaped tracks 1, thus making the left and right inverted T-shaped tracks 1 form a whole, resulting in better track accuracy during use.

[0046] Then, the levitation guide coil 13 or traction coil 14 is fixed to one end of the corresponding first anchor bolt 16, thereby connecting the coil and the first anchor bolt 16. Finally, the other end of the first anchor bolt 16 is inserted into the corresponding adjustment hole 15 and moved and adjusted into place. After filling with anchoring agent, it is anchored in the corresponding adjustment hole 15. Since the inverted T-shaped track 1 will have certain errors during prefabrication and installation, the position of the first anchor bolt 16 and the corresponding coil is precisely adjusted by moving the first anchor bolt 16 laterally or longitudinally in the larger adjustment hole 15. After adjustment, it is filled and fixed with anchoring agent, thus quickly and accurately fixing the levitation guide coil 13 or traction coil 14, further ensuring construction efficiency.

[0047] In other words, the prefabricated superconducting maglev track structure provided by the embodiments of the present invention can not only reduce the concrete pouring on the construction site, but also ensure the integrity and accuracy of the two inverted T-shaped tracks 1, and can quickly and accurately fix the suspension guide coil 13 or traction coil 14, thereby improving construction efficiency.

[0048] It should be noted that the side of the inverted T-shaped track 1 forms the guide wheel support surface 110 of the train, which is located above the first trough 11 and the second trough 12. Furthermore, the prefabricated structures such as the connecting frame 2 and the inverted T-shaped track 1 can use non-magnetic reinforcing bars or non-magnetic high-performance concrete.

[0049] It is easy to understand that the levitation guide coil 13 generates magnetic force to levitate and guide the train, while the traction coil 14 generates magnetic force to power the train's movement.

[0050] For example, the number of adjustment holes 15 can be 4, with the middle 2 adjustment holes 15 used to fix the traction coil 14 and the other 2 coils used to fix the suspension guide coil 13.

[0051] For example, the anchoring agent can be sulfur anchoring mortar, which can solidify and fill quickly.

[0052] In addition, each inverted T-shaped track 1 is provided with a third groove 17 on one side facing the corresponding inverted T-shaped track 1. The third groove 17 is connected to the first groove 11 and the second groove 12, and the third groove 17 is used for inserting cables.

[0053] In other words, by inserting cables into the third cable tray 17, power can be supplied to the levitation guide coil 13 and the traction coil 14.

[0054] Figure 3 This is an assembly diagram of the first anchor bolt provided in an embodiment of the present invention, as shown below. Figure 3 As shown, each of the first anchor bolts 16 has a first positioning nut 161 and a first fastening nut 162 spaced apart at one end. The suspension guide coil 13 or the traction coil 14 is clamped between the first positioning nut 161 and the first fastening nut 162. The coil can be easily clamped by the first positioning nut 161 and the first fastening nut 162, thereby fixing the coil on the first anchor bolt 16.

[0055] See you again Figure 1 The prefabricated superconducting maglev track structure also includes a lower foundation 3 and two spaced adjustment layers 4. Each adjustment layer 4 is located between the lower foundation 3 and the inverted T-shaped track 1 and is a cast-in-place concrete structure.

[0056] In the above implementation, the adjustment layer 4 can be poured on-site after the lower foundation 3 is poured and the inverted T-shaped track 1 is positioned to a suitable height according to the design requirements, thereby smoothing out the construction error of the lower foundation 3.

[0057] For example, pre-embedded connecting steel bars are provided on the lower foundation 3, so that a reliable connection between the lower foundation 3 and the adjustment layer 4 can be achieved by the connecting steel bars when the adjustment layer 4 is poured.

[0058] Similarly, when the inverted T-shaped track 1 does not require position adjustment, each inverted T-shaped track 1 has a portal steel bar inserted at its bottom to fix the inverted T-shaped track 1, thereby fixing the inverted T-shaped track 1 through the portal steel bar.

[0059] In one implementation of the present invention Figure 4 This is an assembly diagram of the second anchor bolt provided in an embodiment of the present invention, as shown below. Figure 4 As shown, each adjustment layer 4 is equipped with a plurality of spaced second anchor bolts 41. One end of the second anchor bolt 41 is inserted into the adjustment layer 4, and the other end of the second anchor bolt 41 passes through the bottom of the inverted T-shaped track 1. The other end of the second anchor bolt 41 is fitted with a second anchor nut 411 to fix the bottom of the inverted T-shaped track 1 to the adjustment layer 4.

[0060] In the above embodiment, by pre-embedding the second anchor bolt 41 and cooperating with the second anchor nut 411, the inverted T-shaped track 1 can be fixed on the adjustment layer 4, so as to avoid relative displacement between the two and affect the positional accuracy of the inverted T-shaped track 1.

[0061] When the inverted T-shaped track 1 needs to be adjusted in position, each inverted T-shaped track 1 is provided with a through hole 18 at the bottom. The diameter of the through hole 18 is larger than the diameter of the second anchor bolt 41. An adjusting ring 19 is detachably inserted into the gap space between the through hole 18 and the second anchor bolt 41 to adjust the position of the inverted T-shaped track 1 laterally. The second anchor nut 411 abuts against the top of the adjusting ring 19.

[0062] Figure 5 This is a schematic diagram of the structure of the first type of adjustment ring provided in the embodiment of the present invention. Figure 6 This is a schematic diagram of the structure of the second type of adjustment ring provided in the embodiments of the present invention, combined with... Figures 5-6 As shown, when installing the inverted T-shaped rail 1, the gap between the through hole 18 and the second anchor bolt 41 is filled by the adjusting ring 19 with its inner hole centered. At this time, the second anchor bolt 41 is located in the center of the through hole 18.

[0063] For example, when the position of the track structure needs to be adjusted during operation:

[0064] When the lower foundation 3 and the adjustment layer 4 drive the inverted T-shaped track 1 to move laterally to the left, loosen the second anchor nut 411, take out the adjusting ring 19 with the inner hole centered, and move the inverted T-shaped track 1 to the right to the appropriate position. At this time, the second anchor bolt 41 is eccentric relative to the through hole 18. Finally, insert the adjusting ring 19 with the corresponding inner hole eccentricity into the through hole 18 and tighten the second anchor nut 411.

[0065] Similarly, when the lower foundation 3 and the adjustment layer 4 cause the inverted T-shaped track 1 to move laterally to the right or longitudinally, the corresponding eccentrically centered adjusting ring 19 can be inserted in the manner described above to adjust the lateral or longitudinal position of the inverted T-shaped track 1. In other words, the position of the inverted T-shaped track 1 can be reasonably adjusted by using the second anchor bolt 41 and the adjusting ring 19 to accommodate unexpected movement of the T-shaped track during operation, thus increasing the applicability of this structure.

[0066] See you again Figure 4 The bottom of the second anchor bolt 41 abuts against the lower foundation 3, and a second positioning nut 412 is fitted on the second anchor bolt 41. The second positioning nut 412 is located below the bottom of the inverted T-shaped track 1 to clamp the bottom of the inverted T-shaped track 1.

[0067] It is easy to understand that the bottom of the second anchor bolt 41 abuts against the lower foundation 3. During the pouring of the adjustment layer 4, the support of the second anchor bolt 41 and the clamping of the second positioning nut 412 and the second anchor nut 411 can automatically support the inverted T-shaped track 1, avoiding the need to use additional hoisting equipment to hoist the inverted T-shaped track 1 during the pouring of the adjustment layer 4.

[0068] For example, the second positioning nut 412 is inserted into the adjustment layer 4, which can simultaneously support the adjusting ring 19 and prevent the adjusting ring 19 from moving downward during the pouring of the adjustment layer 4.

[0069] In addition, a washer is fitted on the other end of the second anchor bolt 41, and the washer is sandwiched between the second anchor nut 411 and the bottom of the inverted T-shaped track 1, thereby increasing the clamping area and preventing the second anchor nut 411 from being embedded in the inverted T-shaped track 1.

[0070] Similarly, a washer is also sandwiched between the second positioning nut 412 and the inverted T-shaped rail 1.

[0071] Figure 7 This is a flowchart illustrating a construction method for a prefabricated superconducting maglev track structure provided in an embodiment of the present invention, as shown below. Figure 7 As shown, this construction method is based on the aforementioned prefabricated superconducting maglev track structure, and the construction method includes:

[0072] S101, prefabricated inverted T-shaped track 1 and connecting frame 2.

[0073] S102. According to the design requirements, two inverted T-shaped tracks 1 are laid at intervals, and a connecting frame 2 is laid between the two inverted T-shaped tracks 1.

[0074] S103. Adjust the lateral spacing of the two inverted T-shaped rails 1, and pour post-pouring strips 22 between both ends of the connecting frame 2 and the corresponding inverted T-shaped rails 1.

[0075] S104. Fix the suspension guide coil 13 or the traction coil 14 to one end of the corresponding first anchor bolt 16.

[0076] S105. After inserting the other end of the first anchor bolt 16 into the corresponding adjustment hole 15 and adjusting it to the correct position, it is then anchored in the corresponding adjustment hole 15 after being filled with anchoring agent.

[0077] The construction method of the prefabricated superconducting maglev track structure provided by this invention can not only reduce the concrete pouring on the construction site, but also ensure the integrity and accuracy of the two inverted T-shaped tracks 1, and can quickly and accurately fix the suspension guide coil 13 or traction coil 14, thereby improving construction efficiency.

[0078] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
