Description

Technical Field

[0001] This invention belongs to the field of civil engineering technology, and in particular relates to a corrugated plate energy dissipation and vibration reduction and self-resetting joint applied to suspended tunnels. Background Technology

[0002] A suspended tunnel is an innovative form of transportation structure that spans deep and long bodies of water. Unlike traditional rock tunnels, undersea tunnels, or immersed tube tunnels, its tube is completely suspended and submerged in water by buoyancy, rather than relying on land for vehicle passage. Simultaneously, a series of underwater anchor cables, anchor bolts, or floating boxes are required to balance the difference between buoyancy and gravity, ensuring that the suspended tunnel does not deform excessively.

[0003] Pipe joints are an important component of suspended tunnel structures, and analyzing their mechanical properties is an indispensable part of suspended tunnel technology research. On the one hand, the mechanical properties of pipe joints influence the mechanical behavior of the suspended tunnel structure to a certain extent, while the construction process often makes pipe joints a weak link in the suspended tunnel structure. On the other hand, the mechanical properties of pipe joints are a crucial factor in determining their waterproofing performance, and the importance of joint waterproofing in the suspended tunnel waterproofing system is self-evident.

[0004] Both suspended tunnels and immersed tunnels are underwater structures, but the working environments of suspended tunnels and immersed tunnels differ significantly. Suspended tunnels are typically located at depths of tens of meters underwater, exposed to complex marine environments such as waves and currents. Under environmental loads, complex relative movements occur between the tunnel sections, leading to misalignment and separation, affecting the stress on the sections. Furthermore, because suspended tunnels are slender structures, their longitudinal stiffness should not be excessive; flexible connection structures should be used to ensure that deformation within a certain allowable range can occur between the sections. While immersed tunnel joints employ flexible connections, their degrees of freedom and deformation capacity cannot meet the requirements of suspended tunnels.

[0005] Currently, there are research and inventions on connecting components for suspended tunnels, but most of them are improvements based on the joint forms of immersed tunnels, and none have been invented specifically for the unique motion characteristics of suspended tunnels. Therefore, it is crucial to find a new connection method suitable for connecting the sections of suspended tunnels, satisfying their relative motion and stress under environmental loads, while ensuring the watertightness between the sections. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a corrugated plate energy-dissipating and vibration-damping self-resetting joint for use in suspended tunnels.

[0007] This corrugated plate energy-dissipating and vibration-damping self-resetting joint, applied to suspended tunnels, includes: a first waterproof structure, a second waterproof structure, and a corrugated plate energy-dissipating structure; one end of the suspended tunnel segment is provided with a tenon, and the other end is provided with a mortise; adjacent segments are connected to each other through a tenon and mortise structure and a corrugated plate energy-dissipating structure.

[0008] The first waterproofing structure includes a GINA waterstop and a sealing rubber ring. The GINA waterstop is placed in the outermost joint of the mortise and tenon structure, and the sealing rubber ring is placed on the outer surface of the tenon. The second waterproofing structure includes an elastic sealing gasket and an OMEGA waterstop. The elastic sealing gasket is placed on the bottom surface of the mortise. The OMEGA waterstop is placed on the inner side of the mortise and tenon structure, and the two ends of the OMEGA waterstop are connected to the adjacent pipe sections respectively.

[0009] The corrugated plate energy dissipation structure is located on the side of the mortise and tenon structure facing the center of the pipe section. Several corrugated plate energy dissipation structures are provided between adjacent pipe sections. The corrugated plate energy dissipation structure includes a double-web H-beam, a square steel pipe, and a base. A corrugated plate is provided on the outer side of the web of the double-web H-beam. The square steel pipe is sleeved on the outer side of the corrugated plate and the double-web H-beam. The two ends of the corrugated plate energy dissipation structure are fixed and connected to the adjacent pipe sections through the base.

[0010] Secondary prestressing tendons and primary prestressing tendons are also provided between adjacent pipe sections. The secondary prestressing tendons pass through the corrugated plate energy dissipation structure, and the primary prestressing tendons pass through the mortise and tenon structure.

[0011] As a preferred embodiment: the outer surface of the tenon is provided with two grooves, and two sealing rubber rings are respectively provided in the grooves on the outer surface of the tenon; the bottom surface of the mortise is also provided with a groove, and the elastic sealing gasket is provided in the groove on the bottom surface of the mortise; both the sealing rubber rings and the elastic sealing gaskets are higher than the opening of the grooves they are located in.

[0012] Preferably, both ends of the corrugated plate are provided with horizontal sections, and the horizontal sections at both ends are tangent to the crests and troughs of the corrugated plate, respectively. When the corrugated plate and the double-web H-beam are placed inside the square steel tube, the horizontal section at one end of the corrugated plate is attached to one side of the web end of the double-web H-beam and connected by bolts, and the horizontal section at the other end is attached to the side wall of the square steel tube and connected by bolts. The number of bolts is greater than or equal to the number of bolts.

[0014] The base is equipped with steel plates. When the steel plates on the two bases are inserted into the two ends of the square steel pipe respectively, the upper and lower ends of the base are attached to the angle steel and connected by bolts. At the end where the corrugated plate horizontal section is attached to the double web H-beam, the steel plate is located outside the corrugated plate horizontal section. At the end where the corrugated plate horizontal section is attached to the side wall of the square steel pipe, the steel plate is located inside the corrugated plate horizontal section.

[0015] As a preferred embodiment: when there is an adjacent corrugated plate energy-dissipating structure on one side of the corrugated plate energy-dissipating structure, the angle steel on that side is replaced with channel steel, and the two adjacent corrugated plate energy-dissipating structures are connected to each other by sharing the same channel steel, and the upper and lower flanges of the channel steel are respectively connected to the two corrugated plate energy-dissipating structures by bolts.

[0016] As a preferred embodiment: the base has through holes, and when the secondary prestressing tendon passes through the corrugated plate energy dissipation structure, both ends of the tendon pass through the through holes on the base that pass through both ends of the corrugated plate energy dissipation structure and are anchored. A prestressing tendon cavity is formed between the two webs in the double-web H-beam, and the middle section of the secondary prestressing tendon passes through the prestressing tendon cavity in the double-web H-beam.

[0017] The assembly method for this corrugated plate energy dissipation and vibration reduction and self-resetting joint applied to suspended tunnels includes the following steps:

[0018] Step 1: Install GINA waterstop, sealing rubber ring and elastic sealing gasket on the tenon and mortise structure of adjacent pipe sections, and install the pipe sections by connecting them through the tenon and mortise structure.

[0019] Step 2: Install OMEGA waterstop strip on the inside of the mortise and tenon structure;

[0020] Step 3: Assemble the corrugated plate energy dissipation structure. Connect one end of the two corrugated plates to the two flanges of the double-web H-beam with bolts. Connect the other end of the two corrugated plates to the square steel pipe with bolts. Connect the two ends of the corrugated plate energy dissipation structure to the base with angle steel or channel steel. Pass the secondary prestressing tendons through the prestressing tendon holes in the web of the double-web H-beam and anchor the two ends to the base respectively.

[0021] Step 4: Adjacent corrugated plate energy-dissipating structures are connected by channel steel, and the bottom of the last corrugated energy-dissipating structure is connected to one end of the base by angle steel.

[0022] As a preferred option: when the angle steel is connected to the flange of the double-web H-beam, the inner side of one side is bolted to the inner side of the flange of the double-web H-beam, and the other side faces the outer side of the flange of the double-web H-beam and is bolted to the base; when the angle steel is connected to the square steel tube, the outer side of one side is bolted to the outer side of the flange of the square steel tube, and the other side faces the outer side of the flange of the square steel tube and is bolted to the base.

[0023] As a preferred option: when the channel steel is connected to the double-web H-beam, the inner side of the channel steel flange is bolted to the inner side of the double-web H-beam, and the outer side of the channel steel web is bolted to the base; when the channel steel is connected to the square steel pipe, the outer side of the channel steel flange is bolted to the outer side of the square steel pipe flange, and the outer side of the channel steel web is bolted to the base.

[0024] The beneficial effects of this invention are:

[0025] 1) The prefabricated structure is adopted, and all joint components are pre-processed. The corrugated plate energy-dissipating structure can be assembled by bolts during connection. The pipe section joint adopts the tenon and mortise structure. GINA waterstop, sealing rubber ring and elastic sealing gasket are arranged at the tenon and mortise structure to ensure the waterproof performance of the structure. The water-stopping effect is good and can completely avoid water seepage and leakage at the tunnel joint.

[0026] 2) Multiple corrugated plate energy-dissipating structures are arranged between adjacent pipe sections. By utilizing the structural characteristics of the corrugated plates, the connection has a certain deformation capacity and the energy dissipation capacity of the corrugated plate energy-dissipating structure is increased.

[0027] 3) Secondary prestressing tendons are installed in the corrugated plate energy dissipation structure, which makes it damage controllable and self-resetting, effectively improving the overall structure, making the joints more secure, and improving waterproof performance; after the earthquake, only the corrugated plate needs to be replaced to complete the structural repair, which greatly reduces construction time, road closure time, and minimizes the impact on traffic.

Detailed Implementation

[0036] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that those skilled in the art can make several modifications to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0037] Example 1

[0038] As one example, such as Figures 1 to 6 As shown, this corrugated plate energy-dissipating and vibration-damping self-resetting joint applied to suspended tunnels includes: a first waterproof structure, a second waterproof structure, and a corrugated plate energy-dissipating structure; one end of the suspended tunnel segment is provided with a tenon, and the other end is provided with a mortise, and adjacent segments are connected to each other through a tenon and mortise structure and a corrugated plate energy-dissipating structure.

[0039] like Figure 1 As shown, the first waterproofing structure includes a GINA waterstop 1 and sealing rubber rings 2. The GINA waterstop 1 is located in the outermost joint of the mortise and tenon structure. Two grooves are provided on the outer surface of the tenon, and the two sealing rubber rings 2 are respectively located within these grooves. The second waterproofing structure includes an elastic sealing gasket 3 and an OMEGA waterstop 4. A groove is also provided on the bottom surface of the mortise, and the elastic sealing gasket 3 is located within this groove. Both the sealing rubber rings 2 and the elastic sealing gasket 3 extend above the opening of their respective grooves. The OMEGA waterstop 4 is located inside the mortise and tenon structure, with its two ends connected to adjacent pipe sections. The first and second waterproofing structures ensure the structure's waterproof performance, providing excellent water-stopping effect and completely preventing seepage and leakage at the tunnel joint.

[0040] like Figures 2a to 6 As shown, the corrugated plate energy-dissipating structure is located on the side of the mortise and tenon structure facing the center of the pipe section. Several corrugated plate energy-dissipating structures are provided between adjacent pipe sections. The corrugated plate energy-dissipating structure includes a double-web H-beam 5, a square steel tube 6, and a base 10. A corrugated plate 11 is provided on the outer side of the web of the double-web H-beam 5. The square steel tube 6 is sleeved on the outer side of the corrugated plate 11 and the double-web H-beam 5. The two ends of the corrugated plate energy-dissipating structure are fixed and connected to adjacent pipe sections through the base 10. Both ends of the corrugated plate 11 are provided with horizontal sections, and the horizontal sections at both ends are tangent to the crest and trough of the corrugated plate 11, respectively. When the corrugated plate 11 and the double-web H-beam 5 are located inside the square steel tube 6, the horizontal section at one end of the corrugated plate 11 is attached to the end of one side of the web of the double-web H-beam 5 and connected by bolts, and the horizontal section at the other end is attached to the side wall of the square steel tube 6 and connected by bolts. The number of bolts is greater than or equal to 6.

[0041] At one end where the horizontal section of the corrugated plate 11 is attached to the double-web H-beam 5, angle steel 7 is also connected to the inner side of the upper and lower flanges of the double-web H-beam 5; at one end where the horizontal section of the corrugated plate 11 is attached to the side wall of the square steel tube 6, angle steel 7 is provided on both the upper and lower outer surfaces of the square steel tube 6.

[0042] A steel plate 8 is provided on the base 10. When the steel plates 8 on the two bases 10 are respectively inserted into the two ends of the square steel pipe 6, the upper and lower ends of the base 10 are attached to the angle steel 7 and connected by bolts; at the end where the horizontal section of the corrugated plate 11 is attached to the double web H-beam 5, the steel plate 8 is located outside the horizontal section of the corrugated plate 11; at the end where the horizontal section of the corrugated plate 11 is attached to the side wall of the square steel pipe 6, the steel plate 8 is located inside the horizontal section of the corrugated plate 11.

[0043] like Figure 1 As shown, when there is an adjacent corrugated plate energy-dissipating structure on one side of the corrugated plate energy-dissipating structure, the angle steel 7 on that side is replaced with channel steel 9, and the two adjacent corrugated plate energy-dissipating structures are connected to each other by sharing the same channel steel 9. The upper and lower flanges of the channel steel 9 are respectively connected to the two corrugated plate energy-dissipating structures by bolts. A gap is left between each corrugated plate energy-dissipating structure for structural deformation and self-resetting function.

[0044] like Figures 1 to 3 As shown, secondary prestressing tendons 12 and main prestressing tendons 13 are also provided between adjacent pipe sections. Through holes are opened on the base 10. When the secondary prestressing tendons 12 penetrate the corrugated plate energy-dissipating structure, both ends pass through and are anchored through the through holes on the base 10 penetrating both ends of the corrugated plate energy-dissipating structure. A prestressing tendon cavity is formed between the double webs within the double-web H-beam 5. The middle section of the secondary prestressing tendon 12 passes through the prestressing tendon cavity within the double-web H-beam 5. The main prestressing tendon 13 passes through the mortise and tenon structure.

[0045] Example 2

[0046] As another embodiment, the assembly method of the corrugated plate energy dissipation and vibration reduction and self-resetting joint for suspended tunnels proposed in Embodiment 1 includes the following steps:

[0047] Step 1: Install GINA waterstop 1, sealing rubber ring 2 and elastic sealing gasket 3 on the mortise and tenon structure of adjacent pipe sections, and install the pipe sections by connecting them through the mortise and tenon structure.

[0048] Step 2: Install OMEGA waterstop 4 on the inside of the mortise and tenon structure;

[0049] Step 3: Assemble the corrugated plate energy-dissipating structure. Connect one end of the two corrugated plates 11 to the two flanges of the double-web H-beam 5 with bolts. Connect the other end of the two corrugated plates 11 to the square steel pipe 6 with bolts. Connect both ends of the corrugated plate energy-dissipating structure to the base 10 through angle steel 7 or channel steel 9. The secondary prestressing tendons 12 pass through the prestressing tendon holes in the web of the double-web H-beam 5 and are anchored at both ends to the base 10. When the angle steel 7 is connected to the flange of the double-web H-beam 5, the inner side of one side is bolted to the inner side of the flange of the double-web H-beam 5, and the other side faces the outer side of the flange of the double-web H-beam 5 and is bolted to the base 10. When the angle steel 7 is connected to the square steel pipe 6, the outer side of one side is bolted to the outer side of the flange of the square steel pipe 6, and the other side faces the outer side of the flange of the square steel pipe 6 and is bolted to the base 10.

[0050] Step 4: Adjacent corrugated plate energy-dissipating structures are connected by channel steel 9. The bottom of the last corrugated energy-dissipating structure is connected to one end of the base 10 by angle steel 7. When channel steel 9 is connected to double-web H-beam 5, the inner side of the flange of channel steel 9 is bolted to the inner side of the flange of double-web H-beam 5, and the outer side of the web of channel steel 9 is bolted to the base 10. When channel steel 9 is connected to square steel tube 6, the outer side of the flange of channel steel 9 is bolted to the outer side of the flange of square steel tube 6, and the outer side of the web of channel steel 9 is bolted to the base 10.

[0051] The working mechanism of the corrugated plate energy dissipation structure is as follows: First, one end of the double-web H-beam 5 and square steel tube 6 in the corrugated plate energy dissipation structure is anchored to the base 10 by angle steel 7, and the other end is connected to the corrugated plate 11. The amplitude of the corrugated plate 11 is limited by the web of the double-web H-beam 5 and square steel tube 6. The double-web H-beam 5, square steel tube 6 and corrugated plate 11 achieve tension equilibrium under the constraint of the secondary prestressing tendons 12. Second, under the action of horizontal force, due to the constraint of the double-web H-beam 5 and square steel tube 6, the corrugated plate 11 undergoes multi-stage buckling, avoiding the single-wave buckling of ordinary steel plates. In addition, when the horizontal tension increases, the lateral displacement of the joints of the multiple secondary prestressing tendons 12 and the main prestressing tendons 13 is limited, thereby limiting the movement. After the earthquake, only the corrugated plate 11 in the corrugated plate energy dissipation structure needs to be replaced to complete the structural repair, which greatly reduces the construction time, reduces the road closure time, and minimizes the impact on traffic.
