Description

Technical Field

[0001] The utility model relates to the technical field of tunnel excavation, in particular to a long-distance TBM construction tunnel vehicle passing traffic structure platform. Background Art

[0002] With the continuous improvement of tunnel boring machine manufacturing technology, many long and large tunnels in China use TBM (full-section tunnel boring machine) to replace the traditional drilling and blasting method. Among them, the TBM single-head excavation distance is as long as 18km, and the maximum daily footage is as high as more than 70 meters. The high footage puts forward high standards for construction traffic in the tunnel. Most of the domestic TBM construction tunnels have circular cross-sections. The use of rail transportation has the advantages of high safety performance and easy operation, and has been widely promoted and applied.

[0003] Rail transport in TBM construction tunnels usually uses a locomotive to pull a train plate for transportation. Due to the cross-section of the cavern, the conventional transportation plan mainly uses single-line transportation. During the tunnel excavation process, more materials and equipment are transported, resulting in greater transportation pressure. Therefore, simple single-line transportation can no longer meet construction needs. In serious cases, it will affect the construction progress and cause TBM shutdown. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the specification of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] See also Figure 1-Figure 3 The utility model provides a long-distance TBM construction tunnel passing traffic structure platform, which includes: a passing section 1, and an uphill section 2 and a downhill section 3 which are arranged on both sides of the passing section 1 and connected.

[0027] In some embodiments, the passing section 1 is a four-track structure for bidirectional travel, and the uphill section 2 and the downhill section 3 are double-track structures for unidirectional travel. By setting the passing section 1 as a four-track structure for bidirectional travel, the passing section 1 is used to pass the locomotives traveling in both directions, so that the rail transportation in the TBM construction tunnel can be designed from a simple single-track transportation to a two-way transportation.

[0028] Furthermore, a first single-open turnout 4 is provided at the connection between the passing section 1 and the uphill section 2, and a second single-open turnout 5 is provided at the connection between the passing section 1 and the downhill section 3, wherein the first single-open turnout 4 and the second single-open turnout 4 are both used to adjust the traveling direction of the locomotive. In some embodiments, a dedicated person is arranged to be in charge of the turnout switches of the first single-open turnout 4 and the second single-open turnout 4, and the first single-open turnout 4 and the second single-open turnout 4 are used to select a suitable track, so that the locomotives in bidirectional transportation are stopped in the passing section 1 respectively, so as to achieve the function of passing the locomotives in bidirectional transportation.

[0029] In some embodiments, the train passing section 1 includes: a first cross brace 11, a first leg 12 provided below and connected to the first cross brace 11, and a support steel plate 13 connecting the first cross brace 11 to the first leg 12. In some embodiments, the first cross brace 11 is provided perpendicular to the track and is used to support the bidirectional track provided on the first cross brace 11, the bottom of the first leg 12 is connected to the rock wall, and both ends of the first cross brace 11 are connected to the rock wall, so that the first cross brace 11 is supported by the first leg 12, and the bidirectional track is supported by the first cross brace 11.

[0030] In some embodiments, the contact surface between the first cross brace 11 and the rock wall is further provided with a first contact surface steel plate 14, and the first contact surface steel plate 14 is used to increase the contact area between the first cross brace 11 and the rock wall, thereby dispersing a portion of the load on the first cross brace 11 to the rock wall, thereby avoiding sinking of the sleeper due to excessive load acting on the first leg 12, causing an accident.

[0031] In some embodiments, the supporting steel plate 13 is a reinforcing plate connecting the first cross brace 11 and the first supporting leg 12 , and is used to enhance the stability of the connection between the first cross brace 11 and the first supporting leg 12 .

[0032] In some embodiments, connecting members 15 are further connected between adjacent first legs 12 to support the stability of the first legs 12 .

[0033] Furthermore, the uphill section 2 has the same structure as the downhill section 3, and is used to support the locomotive for transportation, and includes: a second cross brace 21, a second leg 22 disposed below the second cross brace 21, and second contact surface steel plates 23 disposed at both ends of the second leg 22, and the second cross brace 21 is connected to the rock wall via the second contact surface steel plates 23. In some embodiments, the bottom of the second leg 22 is connected to the rock wall, so that the second cross brace 21 is supported by the second leg 22, and the second cross brace 21 plays a role in supporting the one-way track. Of course, by providing the second contact surface steel plate 23, part of the load on the second cross brace 21 can also be dispersed to the rock wall, thereby avoiding the sinking of the sleeper due to excessive load acting on the second leg 22, causing an accident.

[0034] In some embodiments, the first cross brace 11, the first leg 12, the second cross brace 21 and the second leg 22 are all made of steel sections, which have the advantages of high strength and high bearing capacity, and can provide excellent support for the track.

[0035] It can be understood that the passing section 1 is bidirectional and has a higher load than the uphill section 2 and the downhill section 3 which are unidirectional. The stability of the passing section 1 can be effectively guaranteed by providing the supporting steel plate 13 and the connecting member 15 .

[0036] Finally, it should be noted that the embodiments of the present invention disclose only preferred embodiments of the present invention, which are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
