[0002] The small-diameter tunnel construction has the characteristics of limited operation space, and part of the equipment cannot be centered due to space problems, so there is an eccentric track. In addition, the overall height of the normal track is large due to the stacking arrangement of the track and the sleeper, which further compresses the tunnel space, thereby limiting the operation of various facilities in the tunnel due to insufficient space. For example, the distance between the electric locomotive and the top is small after passing through the track, the tunnel ventilation stack cannot be normally installed, the diameter of the ventilation pipe needs to be reduced, resulting in a decrease in ventilation efficiency; the pipe segments cannot enter the single-beam hoisting area due to the high height after being stacked on the electric locomotive, and the pipe segments need to be stored separately, thereby the length of the electric locomotive needs to be lengthened, resulting in a prolonged hoisting time and a decreased construction efficiency.

[0027] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and cannot be understood as a limitation of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0028] As Figure 1 and Figure 2 shown, the present disclosure proposes a support device for a tunnel eccentric track, comprising: a base 1, a sleeper 2, a first bracket 3 and a second bracket 4, the base 1 is arranged on the segment at the bottom of the tunnel, the sleeper 2 is arranged on the base 1, and the sleeper 2 is provided with a clamping groove 23 penetrating along the length direction of the tunnel, the clamping groove 23 is used for clamping the rail bottom of the first track 5, the first bracket 3 is arranged on the segment at the bottom of the tunnel, and one end of the first bracket 3 and the sleeper 2 is connected, the second bracket 4 is arranged on the segment at the bottom of the tunnel, and one end of the second bracket 4 and the sleeper 2 away from the first bracket 3 is connected.

[0029] It can be understood that, since the first bracket 3 is connected to one end of the sleeper 2, and the second bracket 4 is connected to the end of the sleeper 2 away from the first bracket 3, the sleeper 2 can be stably supported on the segment on the bottom of the tunnel by the first bracket 3 and the second bracket 4, and since the foundation 1 is arranged on the segment on the bottom of the tunnel, and the sleeper 2 is arranged on the foundation 1, the sleeper 2 is provided with a clamping groove 23 penetrating along the length direction of the tunnel, so that the first track 5 can be clamped on the sleeper 2 by the clamping groove 23, and stably arranged on the segment on the bottom of the tunnel by the sequential support of the sleeper 2 and the foundation 1, thereby realizing the stable arrangement of the first track 5 in the tunnel, and further ensuring the stable running of the electric locomotive and other vehicles in the tunnel.

[0030] Moreover, the first track 5 is arranged on the sleeper 2 by clamping of the clamping groove 23, which not only can reduce the use of fixing members and the cost of the support device, but also can effectively reduce the superimposed height of the first track 5 and the sleeper 2, so as to make the tunnel have a larger working space, and further ensure the efficient construction work in the tunnel.

[0031] It should be noted that, in related embodiments, the first track 5 can use wooden sleepers 2, concrete sleepers 2, steel sleepers, etc. Specifically, the wooden sleeper 2 is made of wood, usually high-quality wood after corrosion protection treatment, and has the advantages of good elasticity, light weight, easy processing and installation, etc., but has the disadvantages of easy decay, relatively short service life, and the need for regular replacement and maintenance, etc. The concrete sleeper 2 is made of concrete, which can be internally provided with steel bars to enhance its strength, and has the advantages of high strength, good durability, not easy to deform, low maintenance cost, etc., but has the disadvantages of relatively poor elasticity, high requirement for the ballast bed, not easy to disassemble after construction, and not suitable for short-term construction projects. The steel sleeper is made of steel, has very high strength and can bear large loads, and is suitable for some special track environments, such as heavy-load railways or areas with extremely high requirements for track strength, but has high cost and heavy weight.

[0032] However, the wooden sleeper 2, the concrete sleeper 2, and the steel sleeper all use the laminated arrangement mode to support the first track 5, resulting in a large superimposed height of the first track 5 and the sleeper 2. In the present embodiment, due to the height avoidance effect of the clamping groove 23, the superimposed height of the first track 5 and the sleeper 2 is greatly reduced, thereby reducing the occupation of the tunnel space. For example, after the electric locomotive passes through the first track 5 of the present embodiment, a safe distance can be reserved from the top, the ventilation stack of the tunnel can be normally installed without the need to reduce the diameter of the ventilation pipe, thereby ensuring high ventilation efficiency and quality. After the segments are stacked on the electric locomotive, the height still has a certain passing allowance, which can enter the single-beam hoisting area, thereby avoiding the need to store the segments separately, avoiding the lengthening of the electric locomotive, and further avoiding the prolongation of the hoisting time, thereby ensuring high construction efficiency.

[0033] The first track 5 comprises two parallel steel rails having upper and lower flanges and a web disposed between the upper and lower flanges, and the rail bottom of the first track 5 can be a combined structure of the lower flange and the bottom of the web, and the clamping groove 23 can also be provided in two groove bodies to clamp the two steel rails, respectively.

[0034] The foundation 1 is used to support the sleeper 2, and the specific type of the foundation 1 can be set according to actual needs, which is not limited.

[0035] The sleeper 2 is used to support the first track 5, and the clamping of the clamping groove 23 is used to fix the first track 5, and the specific type of the sleeper 2 can be set according to actual needs, which is not limited.

[0036] The first bracket 3 and the second bracket 4 are both bracket structures, which are used to better transmit the vertical load to the pipe piece and ensure the stable arrangement of the sleeper 2, and the specific type of the first bracket 3 and the second bracket 4 can be set according to actual needs, which is not limited.

[0037] As shown in Figure 1 and Figure 2 In some embodiments, the sleeper 2 comprises a bottom plate 21 and at least one side plate 22, the bottom plate 21 is arranged on the foundation 1 along the width direction of the tunnel, the side plate 22 is arranged on the bottom plate 21 along the width direction of the tunnel, and the clamping groove 23 penetrates through the side plate 22 along the length direction of the tunnel. Wherein, the first bracket 3 is connected to one end of the bottom plate 21 away from the second bracket 4 and one end of the side plate 22 away from the second bracket 4, respectively, and the second bracket 4 is connected to one end of the bottom plate 21 away from the first bracket 3 and one end of the side plate 22 away from the first bracket 3, respectively.

[0038] It can be understood that, since the bottom plate 21 is arranged on the foundation 1 along the width direction of the tunnel, and the side plate 22 is arranged on the bottom plate 21 along the width direction of the tunnel, and the clamping groove 23 penetrates through the side plate 22 along the length direction of the tunnel, the bottom plate 21 and the side plate 22 form an effective support structure in the width direction of the tunnel, so that when the rail bottom of the first track 5 is clamped in the clamping groove 23, the stable arrangement of the first track 5 in the tunnel can be realized.

[0039] Since the first bracket 3 is connected to one end of the bottom plate 21 away from the second bracket 4 and one end of the side plate 22 away from the second bracket 4, respectively, and the second bracket 4 is connected to one end of the bottom plate 21 away from the first bracket 3 and one end of the side plate 22 away from the first bracket 3, respectively, the first bracket 3 and the second bracket 4 can form effective supports at both ends of the bottom plate 21 and both ends of the side plate 22, respectively, so as to further ensure the stable arrangement of the sleeper 2 in the tunnel.

[0040] It should be noted that the bottom plate 21 is the main support structure of the sleeper 2, which is used to cooperate with the side plate 22 to realize the support of the first track 5. The specific type of the bottom plate 21 can be set according to actual needs, and no limitation is made to this. For example, the bottom plate 21 is a horizontally arranged steel plate structure.

[0041] The side plate 22 is an auxiliary support structure of the sleeper 2, which is used to cooperate with the bottom plate 21 to realize the support of the first track 5. The specific type of the side plate 22 can be set according to actual needs, and no limitation is made to this. For example, the side plate 22 is a vertically arranged steel plate structure.

[0042] As shown in Figure 1 and Figure 2 In some embodiments, at least one side plate 22 includes: a first side plate 221 and a second side plate 222. The first side plate 221 is arranged on the bottom plate 21 along the width direction of the tunnel, and the first side plate 221 is provided with first clamping grooves 231 distributed along the length direction of the tunnel. The second side plate 222 is arranged on the bottom plate 21 along the width direction of the tunnel, and the second side plate 222 is provided with second clamping grooves 232 distributed along the length direction of the tunnel. Wherein, the first side plate 221 and the second side plate 222 are spaced apart along the length direction of the tunnel, and the first clamping grooves 231 and the second clamping grooves 232 coincide in the length direction of the tunnel. The first clamping grooves 231 and the second clamping grooves 232 are used for clamping the rail bottom of the first track 5.

[0043] It can be understood that, since the first side plate 221 is arranged on the bottom plate 21 along the width direction of the tunnel, and the first side plate 221 is provided with first clamping grooves 231 distributed along the length direction of the tunnel, the cooperation of the bottom plate 21 and the first side plate 221 can realize a stable support structure. And, since the second side plate 222 is arranged on the bottom plate 21 along the width direction of the tunnel, and the second side plate 222 is provided with second clamping grooves 232 distributed along the length direction of the tunnel, the cooperation of the bottom plate 21 and the second side plate 222 can realize a stable support structure. Therefore, under the cooperation of the bottom plate 21, the first side plate 221 and the second side plate 222, the stable arrangement of the first track 5 in the tunnel is ensured.

[0044] It should be noted that the first side plate 221 and the second side plate 222 are structures of the side plate 22, and the first clamping grooves 231 and the second clamping grooves 232 are clamping groove structures. The first clamping grooves 231 on the first side plate 221 and the second clamping grooves 232 on the second side plate 222 cooperate to realize the clamping of the first track 5. At the same time, the structure of the bottom plate 21 cooperating with the first side plate 221 and the second side plate 222 makes the sleeper 2 can be made of channel steel.

[0045] In addition, a groove structure is formed between the end of the first side plate 221 and the end of the second side plate 222, which can be used for clamping the first corbel 3 and the second corbel 4.

[0046] As Figure 1 shown, in some embodiments, the card slot 23 includes: a first slot 233 and a second slot 234. The first slot 233 penetrates through the side plate 22 along the length direction of the tunnel, and the first slot 233 is used to clamp the lower wing plate of the first track 5. The second slot 234 penetrates through the side plate 22 along the length direction of the tunnel, and the second slot 234 is connected to the first slot 233. One end of the second slot 234 far from the first slot 233 extends out of the side plate 22, and the second slot 234 is used to clamp the web of the first track 5.

[0047] It can be understood that since the first slot 233 and the second slot 234 penetrate through the side plate 22 along the length direction of the tunnel and are connected to each other, and one end of the second slot 234 far from the first slot 233 extends out of the side plate 22, the first slot 233 can clamp the lower wing plate of the first track 5, and the second slot 234 can clamp the web of the first track 5. Thus, through the cooperation of the first slot 233 and the second slot 234, the stable clamping of the first track 5 on the side plate 22 can be achieved, and further the stable arrangement of the first track 5 in the tunnel is ensured.

[0048] It should be noted that the first slot 233 is used to clamp the lower wing plate of the first track 5, and the second slot 234 is used to clamp the web of the first track 5. Based on the "I"-shaped structure of the first track 5, the first slot 233 and the second slot 234 form a slot body similar to the shape of a "mountain". <0​​​​​​​​​​​The base 41 and the segment are in contact with each other due to the bottom of the base 41 and the bottom of the tunnel, so that the base 41 and the segment have a large contact area, so that the base 41 can be stably arranged in the tunnel, and the vertical load can be better transmitted to the segment.

[0052] It should be noted that the base 41 is a main support structure of the first bracket 3 and the second bracket 4, and is used to stably support the end of the sleeper 2 by the reinforced plate 42. The specific type of the base 41 can be set according to actual needs, and is not limited. For example, the base 41 can be a structure close to a wedge.

[0053] The reinforced plate 42 is an auxiliary reinforcing structure of the first bracket 3 and the second bracket 4, and is used to stably support the end of the sleeper 2 in cooperation with the base 41. The specific type of the reinforced plate 42 can be set according to actual needs, and is not limited. For example, the reinforced plate 42 can be a channel steel structure.

[0054] Due to the fact that the symmetry center line of the support device and the symmetry center line of the tunnel do not coincide, the base 41 and the reinforced plate 42 in the first bracket 3 and the base 41 and the reinforced plate 42 in the second bracket 4 are arranged slightly differently. For example, the symmetry center line of the support device is located on the side of the symmetry center line of the tunnel close to the second bracket 4, so that the height dimension of the base 41 in the first bracket 3 is greater than the height dimension of the base 41 in the second bracket 4, so that the top of the base 41 in the first bracket 3 and the top of the base 41 in the second bracket 4 can be located in the same horizontal plane. Correspondingly, the inclination angle of the reinforced plate 42 in the first bracket 3 is also greater than the inclination angle of the reinforced plate 42 in the second bracket 4.

[0055] As shown in Figure 1 and Figure 2 In some embodiments, the first bracket 3 and the second bracket 4 each further include a first stop block 43 and a second stop block 44. The first stop block 43 is arranged on the base 41, and the second stop block 44 is arranged on the base 41. The first stop block 43 and the second stop block 44 are spaced apart along the length direction of the tunnel, and a mounting groove is formed between the first stop block 43 and the second stop block 44. The mounting groove is used to clampingly arrange the rail bottom of the second rail.

[0056] It can be understood that, since the first stop block 43 is arranged on the base 41, the second stop block 44 is arranged on the base 41, and the first stop block 43 and the second stop block 44 are spaced apart along the length direction of the tunnel, the mounting groove formed between the first stop block 43 and the second stop block 44 can clampingly arrange the rail bottom of the second rail, so as to ensure the stable arrangement of the second rail in the tunnel, thereby meeting the walking needs of motor vehicles and the like.

[0057] It should be noted that the first block 43 and the second block 44 are used to form the rail bottom of the second rail, and the specific type of the first block 43 and the second block 44 can be set according to actual needs, and the specific type of the first block 43 and the second block 44 is not limited, for example, the first block 43 and the second block 44 can be square steel, and are welded on the base 41.

[0058] As shown in Figure 1 and Figure 2 In some embodiments, the first bracket 3 and the second bracket 4 each further include: a baffle plate 45, the baffle plate 45 is arranged at one end of the reinforced plate 42 away from the base 41, and the side of the baffle plate 45 away from the reinforced plate 42 in the first bracket 3 abuts against one end of the sleeper 2 away from the second bracket 4, and the side of the baffle plate 45 away from the reinforced plate 42 in the second bracket 4 abuts against one end of the sleeper 2 away from the first bracket 3; and a protrusion 46, the protrusion 46 is arranged at the side of the baffle plate 45 away from the reinforced plate 42, and the protrusion 46 of the first bracket 3 is clamped with one end of the sleeper 2 away from the second bracket 4, and the protrusion 46 of the second bracket 4 is clamped with one end of the sleeper 2 away from the first bracket 3.

[0059] It can be understood that, since the baffle plate 45 is arranged at one end of the reinforced plate 42 away from the base 41, and the side of the baffle plate 45 away from the reinforced plate 42 in the first bracket 3 abuts against one end of the sleeper 2 away from the second bracket 4, and the side of the baffle plate 45 away from the reinforced plate 42 in the second bracket 4 abuts against one end of the sleeper 2 away from the first bracket 3, the first bracket 3 can realize force transmission between the first bracket 3 and the sleeper 2 by using the baffle plate 45, and the second bracket 4 can realize force transmission between the second bracket 4 and the sleeper 2 by using the baffle plate 45, thereby, through cooperation of the first bracket 3 and the second bracket 4, the stable arrangement of the sleeper 2 in the tunnel is realized.

[0060] At the same time, since the protrusion 46 is arranged at the side of the baffle plate 45 away from the reinforced plate 42, and the protrusion 46 of the first bracket 3 is clamped with one end of the sleeper 2 away from the second bracket 4, and the protrusion 46 of the second bracket 4 is clamped with one end of the sleeper 2 away from the first bracket 3, the first bracket 3 and the sleeper 2 can avoid problems such as slipping and disengaging by clamping the protrusion 46, and the second bracket 4 and the sleeper 2 can avoid problems such as slipping and disengaging by clamping the protrusion 46, thereby, the structural stability between the first bracket 3, the second bracket 4 and the sleeper 2 is ensured, and further, the stable arrangement of the first rail 5 in the tunnel is ensured.

[0061] It should be noted that the baffle plate 45 is used for force transmission between the reinforced plate 42 and the sleeper 2, and the specific type of the baffle plate 45 can be set according to actual needs, and the specific type of the baffle plate 45 is not limited, for example, the baffle plate 45 is a steel plate structure arranged along the length direction of the tunnel.

[0062] The protrusions 46 are used for clamping between the baffle 45 and the sleeper 2, and the specific type of the protrusions 46 can be set according to actual needs, and no limitation is made thereto. For example, the protrusions 46 are a plurality of clamping plates arranged along the tunnel width direction, and the plurality of clamping plates are clamped between the first side plate 221 and the second side plate 222.

[0063] In some embodiments, a preset interval is provided between the bottom of the stiffened plate 42 in the first bracket 3 and the tunnel bottom segment, and the bottom of the stiffened plate 42 in the second bracket 4 is attached to the tunnel bottom segment.

[0064] It can be understood that, due to the preset interval between the bottom of the stiffened plate 42 in the first bracket 3 and the tunnel bottom segment, and the attachment of the bottom of the stiffened plate 42 in the second bracket 4 to the tunnel bottom segment, the arrangement of the first bracket 3 and the second bracket 4 can adapt to the off-center structure of the first track 5 in the tunnel, thereby ensuring the stable arrangement of the first track 5.

[0065] It should be noted that the preset interval can be determined according to the interval between the symmetry center line of the support device and the symmetry center line of the tunnel, and the size of the tunnel, and no limitation is made thereto.

[0066] As shown in FIGS. Figure 1 and Figure 2 In some embodiments, the foundation 1 includes: a first support 11 and a second support 12, the first support 11 is arranged on the tunnel bottom segment, and the bottom of the first support 11 is attached to the tunnel bottom segment, one end of the sleeper 2 close to the first bracket 3 is arranged on the first support 11, and the second support 12 is arranged on the tunnel bottom segment, and the bottom of the second support 12 is attached to the tunnel bottom segment, one end of the sleeper 2 close to the second bracket 4 is arranged on the second support 12.

[0067] It can be understood that, due to the arrangement of the first support 11 on the tunnel bottom segment, and the attachment of the bottom of the first support 11 to the tunnel bottom segment, one end of the sleeper 2 close to the first bracket 3 is arranged on the first support 11, so that one end of the sleeper 2 close to the first bracket 3 can be stably arranged on the tunnel bottom segment by using the first support 11, and due to the arrangement of the second support 12 on the tunnel bottom segment, and the attachment of the bottom of the second support 12 to the tunnel bottom segment, one end of the sleeper 2 close to the second bracket 4 is arranged on the second support 12, so that one end of the sleeper 2 close to the second bracket 4 can be stably arranged on the tunnel bottom segment by using the second support 12. Therefore, through the cooperation of the first support 11 and the second support 12, the stable arrangement of the sleeper 2 in the tunnel is ensured.

[0068] It should be noted that, due to the non-coincidence of the symmetry center line of the support device and the symmetry center line of the tunnel, the arrangements of the first support 11 and the second support 12 are slightly different. For example, the symmetry center line of the support device is located on the side of the symmetry center line of the tunnel close to the second corbel 4, and the height dimension of the first support 11 is greater than that of the second support 12, so that the top of the first support 11 and the top of the second support 12 can be located in the same horizontal plane.
