Description

Technical Field

[0001] The invention relates to the technical field of suspended tunnels, and in particular to a suspended tunnel pavement and pipe segment self-balancing vibration reduction device based on multi-structure coordination. Background Art

[0002] As a new type of transportation structure that crosses deep and large fjords, floating tunnels are generally composed of a tubular structure floating at a certain depth in the water, an anchor cable (or floating box on the water) system anchored on an underwater foundation, an underwater anti-pull foundation for anchoring the anchor cable device, and structures connected to both banks. The difference between a floating tunnel and a conventional immersed tube tunnel and a shield tunnel is that the tube body is surrounded by water and the supporting structure balances its own gravity and buoyancy, that is, it can remain stable in the water when the buoyancy-to-weight ratio is 1.3. Floating tunnels have outstanding advantages such as little impact on the surrounding environment, no impact from bad weather during the operation phase, and the unit cost does not increase significantly with the width and depth of the water area.

[0003] The outer wall of the suspended tunnel is the core structure of the suspended tunnel, and its structural stability is of vital importance. Water flow, earthquakes and other factors may cause vibration of the suspended tunnel structure. Although the vibration has little effect on the structure, under the long-term periodic action of wave loads, the suspended tunnel structure will suffer fatigue damage, reducing the structural safety. In underwater suspended tunnels, the safety and comfort of passengers are also crucial considerations. Excessive vibration may cause discomfort to passengers, or even physical discomfort, affecting the overall riding experience. The vibration of the tunnel may also affect the surrounding aquatic organisms, thereby affecting the marine ecological environment. Research on vibration reduction structures can improve tunnel safety, reduce the impact of vibration on passengers, improve ride comfort, and reduce the impact on the marine ecology. Therefore, it is very necessary to carry out research and development of vibration reduction structures for suspended tunnels.

[0004] Since there is no successful construction case of suspended tunnels, there is little research on the vibration reduction structure of suspended tunnels in the existing technology. Considering the continuous vibration of suspended tunnels under wave loads, the design and research of tunnel structure vibration reduction structure has guiding reference value for the construction of future suspended tunnel vibration reduction structure. For this reason, we propose a double energy dissipation self-balancing vibration reduction structure device with adjustable pavement of suspended tunnels. Summary of the invention

[0048] Results Analysis

[0049] Depend on Figure 5 , 6 It is known that when the self-balancing vibration reduction device of the suspended tunnel pavement and pipe segment based on multi-structure coordination faces impact load, the maximum displacement of the suspended tunnel and the pavement panel is 0.48mm when the sidewalk slab 1 and the concave pressure-bearing aluminum frame structure 8 are fixed under the larger spring stiffness, and the maximum displacement of the suspended tunnel and the pavement panel is 0.33mm and 0.24mm respectively when the sidewalk slab 1 and the concave pressure-bearing aluminum frame structure 8 are fixed under the equipment spring stiffness. It can be seen that the vibration reduction rate of the larger stiffness (i.e., the vibration reduction effect) and the normal stiffness on the suspended tunnel is 31.25%, and the vibration reduction rate on the pavement panel is 54.17%.

[0050] From the above, we can know that:

[0051] The present invention is directed to the technical problem that the outer wall of the suspended tunnel is the core structure of the suspended tunnel, and its structural stability is of vital importance. Water flow, earthquake and other factors may cause vibration of the suspended tunnel structure. Although the vibration has little effect on the structure, under the long-term periodic action of wave loads, the suspended tunnel structure will produce fatigue damage, reducing the structural safety. In underwater suspended tunnels, the safety and comfort of passengers are also crucial considerations. Excessive vibration may cause discomfort to passengers, or even physical discomfort, affecting the overall riding experience. The vibration of the tunnel may also affect the surrounding aquatic organisms, thereby affecting the marine ecological environment. Research on vibration reduction structures can improve tunnel safety, reduce the impact of vibration on passengers, improve riding comfort, and reduce the impact on marine ecology. Therefore, it is very necessary to carry out research and development of vibration reduction structures for suspended tunnels. Since there is currently no successful case of construction of suspended tunnels, there is little research on vibration reduction structures for suspended tunnels in the prior art. Considering the continuous vibration influence of the suspended tunnel under the action of wave load, the design and research of the tunnel structure vibration reduction structure has a guiding reference value for the implementation and construction of the future suspended tunnel vibration reduction structure. For this reason, we propose a suspended tunnel pavement adjustable double energy dissipation self-balancing vibration reduction structure device; adopting the technical solutions of the above embodiments and through the above settings, this application can certainly solve the above technical problems and achieve the following technical effects:

[0052] The present invention adopts a vibration reduction structure and method different from the existing suspended tunnel through the structural design of the first vibration reduction mechanism and the second vibration reduction mechanism. By installing fixing bolts at different hole positions of the bottom supporting aluminum frame 16 and the sidewalk slab 1, the bottom supporting aluminum frame 16 and the sidewalk slab 1 can be fixedly connected, thereby directly reducing the lateral vibration of the suspended tunnel, and the sidewalk slab 1 can also be separately vibration-reduced, thereby improving the lateral vibration resistance of the sidewalk slab 1, and further increasing the vibration reduction effect of the sidewalk slab 1 through double vibration reduction.

[0053] Analysis of vibration reduction principle: the sidewalk slab 1, the pendulum damper bearing plate 2, the sidewalk slab base 7, and the bottom supporting aluminum frame 16 are connected through the hole 1. At this time, the sidewalk slab 1 is fixedly connected to the bottom supporting aluminum frame 16. Since the bottom supporting aluminum frame 16 is fixedly connected to the outer wall of the suspended tunnel, the sidewalk slab 1 is fixedly connected to the suspended tunnel. At this time, the internal concave pressure-bearing aluminum frame structure 8 and the pendulum damper fan-shaped mass block 10 serve as the internal mass block inside the suspended tunnel. The hydraulic spring shock absorber 12, the adjustable hydraulic spring shock absorber 14, and the lateral vibration reduction device 6 are used as the spring damping unit connecting the internal mass block and the suspended tunnel, so as to reduce the vibration of the entire suspended tunnel.

[0054] The sidewalk slab 1, the pendulum damper bearing plate 2, and the concave pressure-bearing aluminum frame structure 8 are connected by stud bolts through the holes 3, and the sidewalk slab 1 is fixedly connected to the concave pressure-bearing aluminum frame structure 8. At this time, the sidewalk slab 1 can be fixedly connected to the outer wall of the suspended tunnel. The low-center-of-gravity directional wheel 17 is installed on the bottom supporting aluminum frame 16, which can directly bear the vertical gravity of the concave pressure-bearing aluminum frame structure 8, but does not affect the lateral movement of the concave pressure-bearing aluminum frame structure 8. The concave pressure-bearing aluminum frame structure 8 is connected to the bottom supporting aluminum frame 16 through an adjustable hydraulic spring shock absorber 14, one end of which is installed on both sides of the lower end inside the bottom supporting aluminum frame 16, and the other end is installed at a 45° angle to the horizontal at the middle corner position of the concave pressure-bearing aluminum frame structure 8, wherein the adjustable hydraulic spring shock absorber 14 can absorb the horizontal kinetic energy of the concave pressure-bearing aluminum frame structure 8, dissipate energy and reduce vibration for the concave pressure-bearing aluminum frame structure 8 and its connecting structure, and serve as the bearing structure of the concave pressure-bearing aluminum frame structure 8, thereby allowing the adjustable hydraulic spring shock absorber 14 to absorb the horizontal kinetic energy of the sidewalk slab 1. The cable connection knot 3 and the cable connection seat 4 are installed on the pendulum damper bearing plate 2, and the pendulum damper fan-shaped mass block 10 is connected through the cable 5. The mass block is connected to the bottom support aluminum frame 16 through the hydraulic spring shock absorber 12. The hydraulic spring shock absorber 12 is installed in the middle position of the lower end of the bottom support aluminum frame 16, and the other end is installed at two sections of the right-angle side of the fan-shaped mass block at an angle of 18° to the horizontal. The hydraulic spring shock absorber 12 absorbs the horizontal and vertical kinetic energy of the pendulum damper fan-shaped mass block 10, dissipates energy and reduces vibration for the pendulum damper connection structure, and further dissipates energy and reduces vibration for the horizontal kinetic energy of the sidewalk slab 1. The double vibration reduction method further increases the vibration reduction effect on the sidewalk slab 1.
