Description

Technical Field

[0001] The present invention relates to the technical field of tunnels, and more particularly to a herringbone tunnel structure. Background Art

[0002] A tunnel is an engineering structure buried in the earth, a form of human utilization of underground space. A tunnel's structure consists of two parts: the main structure, which consists of the tunnel body and portals; and ancillary facilities, including car shelters, firefighting facilities, emergency communications, and drainage systems. Longer tunnels also have specialized ventilation and lighting equipment.

[0003] Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. Currently, traffic tunnels generally have a single passageway, and for large-span tunnels, the width of the passageway needs to be widened. However, due to the large span, tunnel collapse is easily caused.

[0004] Therefore, how to provide a herringbone tunnel structure that is not prone to collapse is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a herringbone tunnel structure, aiming to at least solve some of the above technical problems.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A herringbone tunnel structure comprises: a middle channel and two side channels, wherein the two side channels are located on both sides of the middle channel, and the middle channel and the two side channels are arranged in a herringbone shape;

[0008] An auxiliary channel is provided between each of the side channels and the middle channel, and the length of each of the auxiliary channels, each of the side channels and the middle channel extends along the x-axis, the width extends along the y-axis, and the height extends along the z-axis. At the same time, a plurality of dampers are connected to each of the auxiliary channels.

[0009] Preferably, the two ends of each damper are connected one-to-one to the two side walls of the corresponding auxiliary channel distributed along the y-axis direction, and all the dampers in each auxiliary channel are distributed in multiple rows along the z-axis direction, and each row has multiple dampers, and the multiple dampers in each row and the two side walls of the corresponding auxiliary channel distributed along the y-axis direction define multiple triangular intervals.

[0010] Preferably, each of the auxiliary channels has a plurality of support columns all extending along the z-axis, and both ends of each support column are correspondingly connected to the two ends of the corresponding auxiliary channel distributed along the z-axis.

[0011] Preferably, each support column includes: a bottom column section, a spring, and a top column section;

[0012] Wherein, the spring is connected between the bottom column section and the top column section, and is arranged coaxially with the bottom column section and the top column section respectively. At the same time, the end of the bottom column section away from the spring is fixed at the bottom end of the corresponding auxiliary channel, and the end of the top column section away from the spring is fixed at the top end of the corresponding auxiliary channel.

[0013] Preferably, each of the auxiliary channels is filled with a stone-earth mixture.

[0014] Preferably, the ports of each of the auxiliary channels are blocked by concrete covers.

[0015] Preferably, the bottom ends of the middle channel and the two side channels all include: a base layer, a bolt reinforcement layer, and a concrete leveling layer, and the base layer, the bolt reinforcement layer, and the concrete leveling layer are arranged in sequence from bottom to top. At the same time, a plurality of first bolts are provided in the bolt reinforcement layer.

[0016] Preferably, a plurality of second bolts are inserted into the top and side walls of the middle channel, each side channel, and each auxiliary channel.

[0017] Through the above technical solutions, it can be seen that compared with the prior art, the present invention discloses a pin-shaped tunnel structure, which can achieve the following technical effects:

[0018] [[ID=2*]]By adopting the above technical solutions, the present invention distributes a tunnel structure with a middle channel and two side channels in a "pin" shape. On the one hand, a large-span channel is converted into three channels (one middle channel and two side channels), thereby reducing the span of one middle channel and each side channel, so it is not easy for the tunnel to collapse due to a large span. On the other hand, the distribution of one middle channel and two side channels in a "pin" shape makes the structure relatively compact and has better stability. In addition, since auxiliary channels are provided between each side channel and the middle channel, and a plurality of dampers are connected in the auxiliary channels, the vibrations generated during the vehicle passing through the middle channel and the side channels can be absorbed by the plurality of dampers, so it is not easy for the parts between each side channel and the middle channel to crack. Therefore, the pin-shaped tunnel structure of the present invention is less likely to collapse. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] An embodiment of the present invention discloses a tunnel structure in a character 'pin' shape, including: an intermediate passage 1 and two side passages 2, and the two side passages 2 are respectively located on both sides of the intermediate passage 1. At the same time, an intermediate passage 1 and two side passages 2 are distributed in a 'pin' shape.

[0027] An auxiliary passage 3 is provided between each side passage 2 and the intermediate passage 1. The lengths of each auxiliary passage 3, each side passage 2, and the intermediate passage 1 all extend along the x-axis direction, the widths all extend along the y-axis direction, and the heights all extend along the z-axis direction. At the same time, a plurality of dampers 4 are connected in each auxiliary passage 3.

[0028] By adopting the above technical solution of the present invention, through a tunnel structure in which an intermediate passage 1 and two side passages 2 are distributed in a 'pin' shape, on the one hand, a large-span passage is converted into three passages (an intermediate passage 1 and two side passages 2), so that the spans of the intermediate passage 1 and each side passage 2 can be reduced, and thus it is not easy for the tunnel to collapse due to a large span. On the other hand, an intermediate passage 1 and two side passages 2 are distributed in a 'pin' shape, so the structure is relatively compact and has good stability.

[0029] In addition, since an auxiliary passage 3 is provided between each side passage 2 and the intermediate passage 1, and a plurality of dampers 4 are connected in the auxiliary passage 3, the vibrations generated during the vehicle passing through the intermediate passage 1 and the side passages 2 can be absorbed by the plurality of dampers 4, so that it is not easy for the parts between each side passage 2 and the intermediate passage 1 to crack, and therefore the tunnel structure in a character 'pin' shape of the present invention is less likely to collapse.

[0030] To further optimize the above technical solution, both ends of each damper 4 are correspondingly connected to two side walls of the corresponding auxiliary passage 3 distributed along the y-axis direction. At the same time, all the dampers 4 in each auxiliary passage 3 are distributed in multiple rows along the z-axis direction, and each row has a plurality of dampers 4, and the plurality of dampers 4 in each row and the two side walls of the corresponding auxiliary passage 3 distributed along the y-axis direction define a plurality of triangular intervals 40.

[0031] The present invention adopts the above-mentioned technical solution. Since all the dampers 4 in each auxiliary channel 3 are distributed in multiple rows along the z-axis direction, and the multiple dampers 4 in each row and the two side walls of the corresponding auxiliary channel 3 distributed along the y-axis direction are limited to multiple triangular intervals 40, the stability of the multiple dampers 4 connected to the auxiliary channel 3 can be improved, and at the same time, the multiple dampers 4 in each auxiliary channel 3 can be distributed more evenly. Moreover, since the two ends of each damper 4 are connected one-to-one to the two side walls of the corresponding auxiliary channel 3 distributed along the y-axis direction, the damper 4 can provide lateral support for the corresponding auxiliary channel 3, so that the auxiliary channel 3 is not easily displaced in the lateral direction, thereby improving the service life of the auxiliary channel 3, and then improving the service life of the middle channel 1 and the two side channels 2.

[0032] In order to further optimize the above technical solution, each auxiliary channel 3 has multiple support columns 5 extending along the z-axis, and the two ends of each support column 5 are connected one-to-one to the two ends of the corresponding auxiliary channel 3 distributed along the z-axis.

[0033] The present invention adopts the above technical solution, providing vertical support for the corresponding auxiliary channel 3 through the support column 5, so that the auxiliary channel 3 is not easily displaced in the vertical direction, thereby improving the service life of the auxiliary channel 3, and further improving the service life of the middle channel 1 and the two side channels 2.

[0034] In order to further optimize the above technical solution, each support column 5 includes: a bottom column section 51, a spring 52 and a top column section 53;

[0035] Among them, the spring 52 is connected between the bottom column section 51 and the top column section 53, and is arranged on the same center line as the bottom column section 51 and the top column section 53 respectively. At the same time, the end of the bottom column section 51 away from the spring 52 is fixed at the bottom end of the corresponding auxiliary channel 3, and the end of the top column section 53 away from the spring 52 is fixed at the top end of the corresponding auxiliary channel 3.

[0036] The present invention adopts the above technical solution, which can make the support column 5 have elastic expansion and contraction variables in the vertical direction, thereby absorbing corresponding vibrations.

[0037] In order to further optimize the above technical solution, each auxiliary channel 3 is filled with a stone-soil mixture 6.

[0038] The present invention adopts the above technical solution, so that the gaps in the auxiliary channel 3 can be filled with the stone-soil mixture 6, thereby further improving the strength of the area between each side channel 2 and the middle channel 1, thereby enhancing the service life of the present invention.

[0039] In order to further optimize the above technical solution, the port of each auxiliary channel 3 is sealed by a concrete cover plate.

[0040] The present invention adopts the above technical solution and blocks the port of the auxiliary channel 3 with a concrete cover plate, thereby preventing debris from entering the auxiliary channel 3 and preventing the stone-soil mixture 6 in the auxiliary channel 3 from leaking out.

[0041] In order to further optimize the above technical solution, each concrete cover building is connected to the corresponding auxiliary channel 3.

[0042] The present invention adopts the above technical solution. On the one hand, it is not easy for the concrete cover plate to fall off the corresponding auxiliary channel 3. On the other hand, since the concrete cover plate fills the port of the corresponding auxiliary channel 3, the strength of the auxiliary channel 3 can be further improved, thereby improving the strength between each side channel 2 and the middle channel 1.

[0043] In order to further optimize the above technical solution, the bottom ends of the middle channel 1 and the two side channels 2 include: a base layer 101, an anchor reinforcement layer 102 and a concrete leveling layer 103, and the base layer 101, the anchor reinforcement layer 102 and the concrete leveling layer 103 are arranged in sequence from bottom to top, and a plurality of first anchors are provided in the anchor reinforcement layer 102.

[0044] The present invention adopts the above-mentioned technical solution. By setting an anchor reinforcement layer 102 on the base layer 101, the strength of the bottom end of the corresponding channel can be improved. Moreover, since a concrete leveling layer 103 is set on the anchor reinforcement layer 102, not only the strength of the bottom end of the corresponding channel can be further improved, but also the bottom end of each channel can be made relatively flat.

[0045] In order to further optimize the above technical solution, a plurality of second anchor rods 9 are inserted into the top and side walls of the middle channel 1, each side channel 2 and each auxiliary channel 3, thereby improving the strength of the top and side walls of the middle channel 1, each side channel 2 and each auxiliary channel 3, so as to further improve the service life of the present invention.

Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
