A tunnel muck conveying system with passing lanes

Abstract

This utility model relates to the field of tunnel construction, specifically a tunnel muck removal and conveying system with a passing lane. The system comprises an enlarged section formed by expanding the cross-section of the main tunnel line; a transport track is set along the main tunnel line; a passing track is located within the enlarged section, with the transport track and passing track connected in parallel within the enlarged section; a drive vehicle runs along either the transport track or the passing track; and shuttle cars are connected to the drive vehicle for loading tunnel muck. The length of the passing track is greater than the sum of the lengths of one drive vehicle and the corresponding shuttle car. In this utility model, while one shuttle car is loading muck, the next shuttle car, driven by the drive vehicle, enters the tunnel first and waits on the passing track. After the previous shuttle car is full, it can still drive directly out along the transport track. When it leaves the passing track, the next shuttle car on the passing track can directly enter the working position to load muck, thus improving the efficiency of tunnel muck removal.

Description

Technical Field

[0001] This utility model relates to the field of tunnel construction, and in particular to a tunnel muck removal and conveying system with a passing lane. Background Technology

[0002] In water diversion projects or oil and gas pipeline projects, it is not necessary to set up large tunnel cross sections. For small cross-section tunnels with cross-sectional width and height dimensions of less than or equal to 3.6m and 3.7m respectively, the space is limited, and the size of vehicles for tunnel excavation and muck removal is restricted. In particular, for the track transport muck removal method, usually only one track can be set up in the small cross-section tunnel. The muck removal vehicle enters along the track, and it needs to wait for it to complete the loading of muck and then exit along the track before the next muck removal vehicle can enter, resulting in low construction efficiency of excavation and muck removal. Utility Model Content

[0003] The purpose of this utility model is to address the problem that existing technologies for small-section tunnels have limited space, allowing only one track for transporting muck removal vehicles, and the next vehicle can only enter after the previous vehicle has finished its work and left the tunnel, resulting in low construction efficiency for excavation and muck removal. This utility model provides a tunnel muck removal and conveying system with a pass-through lane.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tunnel muck removal and conveying system with a passing lane includes an enlarged section, a transport track, a passing track, a drive vehicle, and a shuttle car. The enlarged section is formed based on an enlarged cross-section of the main tunnel line. The transport track is arranged along the main tunnel line. The passing track is located within the enlarged section, and the transport track and the passing track are arranged in parallel within the enlarged section. The drive vehicle runs along either the transport track or the passing track. The shuttle car is connected to the drive vehicle and is used for loading tunnel muck. The length of the passing track is greater than the sum of the lengths of one drive vehicle and the corresponding shuttle car.

[0005] It should be noted that within the extended section, the transport track and the passing track serve as each other's passing lanes.

[0006] The tunnel slag removal and conveying system with a passing lane described in this utility model widens a section of the small-section tunnel, and sets up a passing lane parallel to and connected to the transport track at the widened section. While the first shuttle car is loading slag, the second shuttle car is driven by the drive vehicle to enter the tunnel first and wait on the passing lane. After the first shuttle car is full, it can still drive directly out along the transport track. When it leaves the passing lane, the second shuttle car on the passing lane can directly enter the working position to load slag, thus improving the efficiency of tunnel excavation and slag removal.

[0007] As a preferred technical solution of this utility model, the positive line segment and the enlarged segment are connected by a gradient segment.

[0008] As a further preferred technical solution of this utility model, the length of the gradient section is 2m~3m.

[0009] As a preferred embodiment of this invention, the width of the positive line segment is less than or equal to 3.6m.

[0010] As a preferred technical solution of this utility model, the width of the enlarged section is 4m to 5m.

[0011] As a preferred technical solution of this utility model, both the main line segment and the enlarged segment are provided with system mortar anchors.

[0012] As a preferred technical solution of this utility model, a plurality of the enlarged segments are arranged at intervals along the length direction of the positive line segment.

[0013] As a preferred technical solution of this utility model, the transport track and the passing track are connected by a turnout.

[0014] As a preferred technical solution of this utility model, the driving vehicle is an electric tractor.

[0015] As a preferred technical solution of this utility model, the shuttle mine car is equipped with a slag remover.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The present invention discloses a tunnel slag removal and conveying system with a passing lane. By widening a section of a small-section tunnel (i.e., setting up an enlarged section), a passing lane is set up at the widened section, parallel to and connected to the transport track. When the first shuttle car is loading slag, the next shuttle car is driven by the drive vehicle to enter the tunnel first and wait on the passing lane. After the first shuttle car is full, it can still drive directly out along the transport track. When it leaves the passing lane, the next shuttle car on the passing lane can directly enter the working position to load slag, thus improving the efficiency of tunnel excavation and slag removal.

[0019] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0020] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0022] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0023] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0024] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0025] In related technologies, for small-section tunnels with cross-sectional width and height dimensions less than or equal to 3.6m and 3.7m respectively, space is limited, allowing only one track for the transport of excavated materials. The next vehicle can only enter after the previous one has finished its work and exited the tunnel, resulting in low construction efficiency for excavation and muck removal. Therefore, the technical solution of this application was developed, which is described below in conjunction with... Figures 1 to 3 To elaborate.

[0026] Example 1 like Figures 1 to 3 As shown, the tunnel slag conveying system with passing lanes described in this utility model includes an enlarged section 2, a transport track 4, a passing track 5, a drive vehicle 6, and a shuttle mine car 7.

[0027] The enlarged section 2 is formed by enlarging the cross-section of the main tunnel section 1. The main tunnel section 1 and the enlarged section 2 are connected by a transition section 3. The width of the main tunnel section 1 is less than or equal to 3.6m, the width of the enlarged section 2 is 4m to 5m, and the length of the transition section 3 is 2m to 3m. Both the main tunnel section 1 and the enlarged section 2 are equipped with system mortar anchor bolts, and the surfaces of both the main tunnel section 1 and the enlarged section 2 are reinforced with steel mesh and shotcreted.

[0028] The transport track 4 is set along the main line segment 1; the passing track 5 is set in the enlarged section 2, and the transport track 4 and the passing track 5 are set in parallel in the enlarged section 2. The transport track 4 and the passing track 5 are connected by a turnout; it should be noted that in the enlarged section 2, the transport track 4 and the passing track 5 serve as each other's passing lanes.

[0029] The drive vehicle 6 runs along the transport track 4 or the passing track 5, and the drive vehicle 6 can be an electric tractor; the shuttle mine car 7 is connected to the drive vehicle 6, and the shuttle mine car 7 is used for loading tunnel slag, and the shuttle mine car 7 is equipped with a slag loader, so that the shuttle mine car 7 can load slag by itself; the length of the passing track 5 is greater than the sum of the lengths of one drive vehicle 6 and the corresponding shuttle mine car 7.

[0030] In some alternative embodiments, a plurality of the enlarged segments 2 are provided at intervals along the length direction of the positive line segment 1.

[0031] This embodiment describes a tunnel muck removal and conveying system with a passing lane. By widening a section of the small-section tunnel (i.e., setting up the widened section 2), a passing track 5 is set up parallel to and connected to the transport track 4 at the widened section. When the first shuttle car 7 is loading muck, the second shuttle car 7 is driven by the drive vehicle 6 to enter the tunnel first and wait on the passing track 5. After the first shuttle car 7 is full, it can still drive directly out along the transport track 4. When it leaves the passing track 5, the second shuttle car 7 on the passing track 5 can directly enter the working position to load muck, thus improving the efficiency of tunnel excavation and muck removal.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
