Description

Technical Field

[0001] This application relates to tunnel construction materials, specifically a lining segment for a circular vibration-damping tunnel. Background Technology

[0002] The value of vibration-damping tunnels lies not only in their engineering technology but also in their promotion of a new engineering philosophy that prioritizes both engineering safety and ecological protection, and unifies construction speed with quality and efficiency. With the deep integration of intelligent monitoring technology, future vibration-damping tunnels will develop towards a smarter direction characterized by "self-sensing, self-repairing, and self-adaptation," providing safer and more sustainable solutions for the development and utilization of underground space. This technological evolution is not only progress in the engineering field but also a significant milestone for humanity in addressing geological disasters and achieving sustainable urban development. Lining refers to the permanent support structure constructed around the tunnel body using reinforced concrete and other materials to prevent deformation or collapse of the surrounding rock. Lining technology is commonly used in tunnel engineering and water conservancy projects. Simply put, lining is the inner lining, commonly using block lining, which can also be prestressed high-pressure grouting concrete lining.

[0003] Existing vibration isolation measures for circular vibration-damping tracks mainly involve installing vibration isolation devices at the track. When a train passes, the vibration isolation components can block the vibrations and noise generated at the track. However, this vibration isolation measure mainly isolates the source of vibration, and it is difficult to disperse the noise in actual application. Therefore, vibrations and noise can still pass through the track and affect the outside world. Utility Model Content

[0004] In view of the above-mentioned related technologies, the purpose of this application is to provide a lining segment for a circular vibration-damping tunnel, which can disperse vibration during the use of the lining segment and absorb and block noise. This solves the problem that simply isolating the vibration source is not enough to disperse the noise in practical applications, thus causing vibration and noise to still pass through the track and affect the outside world.

[0005] The lining segment of a circular vibration-damping tunnel provided in this application adopts the following technical solution: it includes a lining pipe body, and multiple keel segments are fixedly connected inside the lining pipe body. The lining pipe body is provided with a vibration-damping structure, which is located between the multiple keel segments. The vibration-damping structure includes a connecting frame, a damping layer, and nylon ropes. The damping layer is fixedly connected inside each of the multiple connecting frames. The upper and lower ends of the multiple damping layers are fixedly connected to the interior of the multiple connecting frames. The multiple connecting frames are arranged in a ring. Multiple nylon ropes are fixedly connected to both sides of the connecting frames. The multiple nylon ropes are arranged in a cross shape. The multiple keel segments are respectively placed on the inner and outer sides of the connecting frames. By adopting the above technical solution, through the setting of shock-absorbing structure, connecting frame, damping layer, nylon rope, and keel plate, multiple damping layers can be fixed in the middle of the connecting frame during use. Then, multiple connecting frames are cross-fixed with nylon rope to form a cylindrical structure consistent with the lining pipe. Next, the shock-absorbing structure and keel plate are placed in the casting mold. After the lining pipe is formed and assembled into a tunnel, when the tunnel vibrates, the shock-absorbing structure can distribute the vibration force to multiple connecting frames. At the same time, the damping layer absorbs the vibration force and noise from multiple positions, thereby achieving the purpose of dispersing vibration and absorbing and blocking noise during the use of the lining pipe segments.

[0006] Preferably, side pipe heads are fixedly connected to both sides of the main body of the masonry pipe, and the side pipe heads and the main body of the masonry pipe have two sets of common concave grooves.

[0007] By adopting the above technical solution, before splicing the lining segments, multiple partition tubes can be combined with multiple sliders and multiple concave grooves, so that the partition tubes can be quickly inserted into the lining segments to provide protection for the devices inside the lining segments.

[0008] Preferably, both sets of concave grooves are slidably connected to T-shaped sliders, and the two sets of sliders are respectively fixedly connected to a common separator tube.

[0009] By adopting the above technical solution, in tunnel engineering, the rough cement surface inside the lining segments can easily cause wear to the internal pipes or the tunnel itself, seriously affecting the service life and safety. Therefore, in order to avoid this problem, a partition pipe is added inside the lining segments, thereby utilizing the smooth surface inside the partition pipe to greatly reduce wear inside the tunnel.

[0010] Preferably, magnetic plates are fixedly connected to both sides of the two partition tubes, and the magnetic plates on the same side of the two partition tubes attract each other.

[0011] By adopting the above technical solution, the separator tube is inserted into the lining segment. At this time, the magnetic plates on both sides of the separator tube attract each other, thereby achieving rapid assembly.

[0012] Preferably, the two side tube heads have multiple through-holes inside, and each of the multiple through-holes is fixedly connected to a nut block by a connector fixing block.

[0013] By adopting the above technical solution, when assembling multiple lining segments, multiple side pipe heads are attached to each other, and the nut blocks in multiple assembly holes are aligned. Then, the workers use tools to tighten the bolt rods so that they are inserted into the multiple nut blocks.

[0014] Preferably, the internal threads of the plurality of nut blocks are fitted with bolt rods, and the plurality of bolt rods can penetrate the two side tube ends.

[0015] By adopting the above technical solution, multiple side pipe heads can be spliced ​​and combined, making the fixing more stable and allowing the lining segment to be disassembled into multiple sections. This makes the transportation of multiple lining segments easier and more convenient, improving the overall efficiency of the project.

[0016] Preferably, one side of each of the two side tube heads is fixedly connected to a plurality of fixing plates, and one side of each of the plurality of fixing plates is fixedly connected to a wave tooth.

[0017] By adopting the above technical solution, the splicing and assembly of multiple lining segments can be completed more quickly, and the splicing will not cause any displacement.

[0018] Preferably, the plurality of fixing plates are arranged vertically and horizontally respectively, and the plurality of wave teeth on one side of the two side tube heads are adapted to each other.

[0019] By adopting the above technical solution, during the assembly process, these wavy teeth approach each other and the tooth peaks are embedded in adjacent tooth valleys, like precise jigsaw puzzle pieces, thereby quickly completing the initial positioning. Furthermore, based on the uniform distribution of the wavy teeth along the fixing plate, force can be applied from multiple points simultaneously, effectively resisting the misalignment deviation during the splicing process. The tooth peaks of the wavy teeth on the fixing plate on the side of the pipe head are spliced ​​together, so that the fixed lining segments can avoid displacement during subsequent use.

[0020] In summary, this application includes at least one of the following beneficial technical effects: This circular vibration-damping tunnel lining segment, through the setting of a vibration-damping structure, connecting frames, damping layers, nylon ropes, and keel plates, allows multiple damping layers to be fixed in the middle of the connecting frames during use. Then, the multiple connecting frames are cross-fixed using nylon ropes, forming a cylindrical structure consistent with the lining pipe. Next, the vibration-damping structure and keel plates are placed in a casting mold. After the lining pipe is formed and assembled into a tunnel, when the tunnel vibrates, the vibration-damping structure can distribute the vibration force to multiple connecting frames, while the damping layers absorb vibration force and noise from multiple locations. This achieves the purpose of dispersing vibration and absorbing and blocking noise during the use of the lining segment.

[0021] This type of circular vibration-damping tunnel lining segment, through the setting of concave grooves, sliders, partition tubes, magnetic plates, as well as assembly holes, nut blocks, bolt rods, and corrugated teeth, allows multiple side tube heads to be attached to each other during use. Simultaneously, the nut blocks in multiple assembly holes are aligned. Then, workers use tools to tighten the bolt rods, inserting them into the multiple nut blocks to achieve the splicing and combination of multiple side tube heads. During the assembly process, the corrugated teeth on one side of the fixing plate of the side tube head are spliced ​​together. Multiple partition tubes are combined with multiple sliders and multiple concave grooves, allowing the partition tubes to enter the lining segment. At this time, the magnetic plates on both sides of the partition tubes attract each other. Based on the even distribution of the corrugated teeth along the fixing plate, force can be applied simultaneously from multiple points, effectively resisting misalignment deviations during the splicing process. This achieves greater stability of the lining segment during the fixing process and prevents the lining segment from shifting. It also avoids the rough cement surface inside the lining segment, which could cause wear on the internal pipes or tunnel. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A lining segment for a circular vibration-damping tunnel, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The system includes a main pipe body 1, with multiple keel plates 3 fixedly connected inside the main pipe body 1. A damping structure 2 is located inside the main pipe body 1, situated between the multiple keel plates 3. The damping structure 2 includes a connecting frame 201, a damping layer 202, and nylon ropes 203. Each connecting frame 201 has a damping layer 202 fixedly connected inside, with both ends of the damping layer 202 fixedly connected to the interior of the connecting frame 201. The connecting frames 201 are arranged in a ring. Multiple nylon ropes 203 are fixedly connected to both sides of each connecting frame 201, forming a cross shape. Multiple keel plates 3 are placed on the inner and outer sides of the connecting frame 201, respectively. The damping structure 2 and the connecting frame 203... The damping layer 202, nylon rope 203, and keel plate 3 are designed so that multiple damping layers 202 can be fixed to the middle of the connecting frame 201 during use. Then, the multiple connecting frames 201 are cross-fixed with nylon rope 203 to form a cylindrical structure consistent with the lining pipe. Next, the damping structure 2 and the keel plate 3 are placed in the casting mold. After the lining pipe is formed and assembled into a tunnel, when the tunnel vibrates, the damping structure 2 can distribute the vibration force to multiple connecting frames 201. At the same time, the damping layer 202 absorbs the vibration force and noise from multiple positions, thereby achieving the purpose of dispersing vibration and absorbing and blocking noise during the use of the lining pipe segments.

[0026] Example 2: A lining segment for a circular vibration-damping tunnel, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The system includes side pipe heads 4 fixedly connected to both sides of the main pipe body 1. Both the side pipe heads 4 and the main pipe body 1 have two sets of common concave grooves 5. T-shaped sliders 6 are slidably connected inside both sets of concave grooves 5. Common partition pipes 7 are fixedly connected between the two sets of sliders 6. Before the lining segments are assembled, multiple partition pipes 7 can be combined with multiple concave grooves 5 via multiple sliders 6, allowing the partition pipes 7 to be quickly inserted into the lining segments, providing protection for the internal devices. Magnetic suction plates 8 are fixedly connected to both sides of the two partition pipes 7. The magnetic plates 8 on the same side of the two partition tubes 7 attract each other. Multiple assembly holes 9 are drilled through the interior of the two side tube heads 4. Nut blocks 10 are fixedly connected to the interior of each assembly hole 9 via connecting fastener blocks. Bolt rods 11 are threaded into the interior of each nut block 10 and can pass through the two side tube heads 4. Multiple fixing plates 12 are fixedly connected to one side of each side tube head 4. Wavy teeth 13 are fixedly connected to one side of each fixing plate 12. The fixing plates 12 are arranged vertically and horizontally respectively. Multiple corrugated teeth 13 on one side of the tube head 4 are adapted to each other. Through the setting of concave grooves 5, sliders 6, partition tubes 7, magnetic plates 8, as well as assembly holes 9, nut blocks 10, bolt rods 11, and corrugated teeth 13, multiple side tube heads 4 can be attached to each other during use. At the same time, the nut blocks 10 in the multiple assembly holes 9 are aligned. Then, the operator uses a tool to tighten the bolt rod 11 so that it passes through the multiple nut blocks 10, realizing the splicing and combination of multiple side tube heads 4. During the combination process, the corrugated teeth 13 on the fixing plate 12 on one side of the side tube head 4... The toothed parts are spliced ​​together, and multiple partition tubes 7 are combined with multiple sliders 6 and multiple concave grooves 5 to allow the partition tubes 7 to enter the interior of the lining segment. At this time, the magnetic plates 8 on both sides of the partition tube 7 attract each other. According to the even distribution of the wave teeth 13 along the fixing plate 12, force can be applied from multiple points at the same time, effectively resisting the misalignment deviation during the splicing process. This achieves greater stability of the lining segment during the fixing process and prevents the lining segment from shifting. It also avoids the rough cement surface inside the lining segment from abrading the internal pipes or tunnels.

[0027] The implementation principle of this application embodiment is as follows: During the manufacturing of the lining segments, preparation work for casting and molding is first carried out. Multiple damping layers 202 are fixed to the middle of the connecting frame 201. Then, nylon ropes 203 are used to cross-fix the multiple connecting frames 201, forming a cylindrical structure consistent with the lining pipe. Next, the shock-absorbing structure 2 and the keel plates 3 are placed in the casting mold, with the multiple keel plates 3 respectively placed on the inner and outer sides of the shock-absorbing structure 2. After the lining pipe is formed and assembled into a tunnel, when the tunnel vibrates, the shock-absorbing structure 2 can disperse the vibration force to the multiple connecting frames 201. At the same time, the damping layers 202 absorb vibration force and noise from multiple locations, while the keel plates 3 are used to reinforce the overall strength of the lining pipe and further block noise. When assembling multiple lining segments, multiple side pipe heads 4 are attached to each other, and the nut blocks 10 in multiple assembly holes 9 are aligned. Then, the workers use tools to tighten the bolt rods 11, so that they are inserted into the multiple nut blocks 10, thereby achieving the splicing and combination of multiple side pipe heads 4. During the assembly process, the toothed portions of the corrugated teeth 13 on one side fixing plate 12 of the side pipe head 4 are spliced ​​together, so that the fixed lining segments are prevented from shifting. Before the lining segments are spliced, multiple partition tubes 7 are combined with multiple sliders 6 and multiple concave grooves 5 to allow the partition tubes 7 to enter the interior of the lining segments. At this time, the magnetic plates 8 on both sides of the partition tubes 7 attract each other, thereby achieving rapid assembly and avoiding wear on the internal pipes or tunnels due to the relatively rough cement surface inside the lining segments.
