[0002] Tunnel engineering is an important part of modern infrastructure construction and is widely used in highways, railways, subways, water conservancy, energy and other fields. With the acceleration of urbanization and the increase in transportation demand, the demand for tunnel construction is also growing. In order to improve efficiency, tunnels usually have multiple sections to carry out tunnel construction with different processes to form an overall tunnel construction line to obtain higher comprehensive construction efficiency.

[0003] In a tunnel, the construction efficiency of the face is the core of the overall tunnel construction advancement efficiency. However, at present, the construction of the face steel arch frame still uses cranes or other lifting equipment to lift each section of the steel arch frame into place one by one, which is inefficient. In addition, in order to control the stability of the tunnel face construction support, the lifting personnel are required to actively control the spacing between the steel arch frames after lifting, which leads to slow lifting operations and high control difficulty, affecting the construction efficiency of the entire tunnel construction line.

[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0033] like Figure 1-4As shown, the present invention provides a tunnel construction production line, including: a steel arch frame module 1, an inverted arch bridge module 2, a waterproof cloth laying module 3, a casting lining module 4, a maintenance module 5 and a groove template module 6 which are set up in sections along the tunnel drilling direction, respectively used for the erection of the steel arch frame, the construction of the inverted arch bridge, the laying of waterproof cloth, the casting lining, the concrete maintenance and the groove construction, and the section-by-section construction is carried out. In addition, in order to improve the overall tunnel construction efficiency, the steel arch frame module 1 includes a lifting mechanism 11, a hanging mechanism 12 and a walking mechanism 13. The hanging mechanism 12 has a plurality of rotatable hooking parts 121 for hooking the steel arch frame. The movable end of the lifting mechanism 11 is movably connected to the hanging mechanism 12, and has the function of hooking the steel arch frame and tilting and stacking. The first position state, and the second position state of hooking the steel arch frame and lifting it to an equidistant vertical state, the walking mechanism 13 is used to drive the suspension mechanism 12 to move along the tunnel axis in the second position state, that is, with the cooperation of the lifting mechanism 11, the suspension mechanism 12 and the walking mechanism 13, multiple steel arch frames are lifted at the same time, and after lifting, they are arranged equidistantly, and the equidistant arrangement is maintained to move to a fixed position. The above structure and operation method avoid the slow progress caused by lifting the steel arch frames one by one, and after lifting, multiple steel arch frames are arranged equidistantly at the same time, forming a position restriction, and there is no need to perform additional slow lifting and moving during lifting to control the interval spacing, and measure and control the spacing. When moving to a fixed position, the moving speed can be increased and efficiently positioned to a fixed position. In addition, in the first position state, the steel arch frames are stacked in an inclined manner, saving space, and when loaded on the suspension mechanism 12, there is no need to lift too high a height, saving loading time. In addition, the use of a structure with direct support at the bottom prevents the steel arch from having a large shaking amplitude. Compared with lifting and moving by hoisting, it has higher stability and is less likely to collide with the rock wall, reducing the probability of causing dangerous accidents. It has the advantages of high efficiency and safety in the construction of the face.

[0034] It can be understood that the lifting mechanism 11 , the suspension mechanism 12 and the traveling mechanism 13 are all installed on the trolley body, forming the main construction equipment of the steel arch frame module 1 .

[0035] In one embodiment, to improve the efficiency of laying and hanging waterproof cloth, please refer to Figure 5 and Figure 6The waterproof cloth laying module 3 includes a basic construction frame 31 and a rolling mechanism 32. The rolling mechanism 32 is installed on the basic construction frame 31 and can move along the basic construction frame 31 toward the tunnel axis to roll the waterproof cloth along the inner circular surface of the tunnel. In the traditional operation mode, after laying the waterproof cloth, it is necessary to manually reinforce the waterproof cloth on the basic construction frame 31, while the traditional waterproof cloth rolling structure directly rolls back and forth on the outside of the basic construction frame 31, which is easy to interfere with the operating area reinforced by the workers, and has unsafe factors. In addition, after laying the waterproof cloth in an area, it needs to be moved. During the movement, the construction is stagnant and there is room for improvement in efficiency. Therefore, the foundation construction frame 31 is the main body, and the rolling mechanism 32 can slide along the foundation construction frame 31 and be positioned separately. At this time, after the first laying, it can slide and move outside the foundation construction frame 31 to avoid overlapping, which will interfere with the previous reinforcement during the next laying, and the previous reinforcement and the next laying can be carried out at the same time. In addition, the foundation construction frame 31 and the rolling mechanism 32 move at the same time. During the movement, since there is no rolling mechanism 32 to block the foundation construction frame 31, workers can perform preliminary reinforcement of the next laying of waterproof cloth during the movement. While improving construction safety, construction efficiency is also improved.

[0036] Furthermore, in order to achieve the purpose of enabling the rolling mechanism 32 to move along the foundation construction frame 31, the rolling mechanism 32 includes a linear drive 321, a guide frame 322, a rotary drive 323 and a laying roller 324. The linear drive 321 is installed on both sides of the foundation construction frame 31, the guide frame 322 is installed between the movable ends of the two linear drives 321, and the rotary drive 323 is installed on the guide frame 322, and its movable end is connected to the laying roller 324, which is used to drive the laying roller 324 to roll the waterproof cloth along the inner circular surface of the tunnel.

[0037] It can be understood that the linear drive component 321 can adopt a linear drive structure such as a screw guide rail, a hydraulic mechanism, etc.; the rotary drive component 323 adopts the industry's traditional double-layer compound track and double-row chain drive to move the laying roller 324 along the guide frame 322 to form a circular paving movement around the tunnel.

[0038] In a certain embodiment, in order to facilitate the replacement of the suspension mechanism 12 and form the transportation, installation and supply of multiple batches of steel arch frames, the suspension mechanism 12 includes a lifting base 122 and a suspension frame 123, the hook portion 121 is rotatably connected to the suspension frame 123, the suspension frame 123 is detachably installed on the lifting base 122, and the hook portion 121 is U-shaped and is used to be mounted on the bottom of the dome of the steel arch frame, wherein the number of suspension frames 123 and hook portions 121 is determined according to the number of steel arch frames that need to be installed simultaneously in a batch, and after the steel arch frame is installed and fixed, the lifting base 122 is lowered in height, and after being detached from the steel arch frame socket position, it can be detached from the steel arch frame after cooperating with the walking mechanism 13 to be translated and driven, and then separated.

[0039] It can be understood that the suspension frame 123 can be disassembled from the lifting base 122, and the steel arch frame can be installed on the suspension frame 123 for transportation, and then hoisted onto the lifting base 122, which can form a quick replacement and carry out the next wave of steel arch frame installation. After being installed in an open area outside the tunnel, it can be directly transported to the heading face to avoid the inconvenience of operation in the tunnel, thereby further improving the construction efficiency.

[0040] In one embodiment, to facilitate lining pouring, please refer to Figure 1 The casting lining module 4 includes a lining casting platform 41. Multiple layers of windows 42 are provided on both sides of the lining casting platform 41. A casting pipeline is provided corresponding to each layer of windows 42 from top to bottom for simultaneous casting on both sides. The casting efficiency is improved by casting on both sides of the layers and windows at the same time, and the problems of segregation and herringbone slope cold joints during casting are solved. The casting pipeline is passed into concrete from bottom to top in sequence according to the layers to form casting.

[0041] In one embodiment, in order to facilitate the construction of the inverted trestle, please refer to Figure 1 The inverted arch trestle module 2 includes an inverted arch pouring platform 21 and a vehicle turning platform 22 arranged along the tunnel drilling direction. The inverted arch pouring platform 21 is used for gradually pouring from the middle to both sides, and is equipped with a tamping mechanism to ensure the pouring quality. The vehicle turning platform 22 is connected with the top of the inverted arch pouring platform 21, and is used for the concrete pouring vehicle to drive to the top of the inverted arch pouring platform 21 to supply concrete to the double-channel pouring mechanism. A rotating table 221 is provided on the vehicle turning platform 22, which is used to rotate the direction to make the concrete pouring vehicle turn around.

[0042] In one embodiment, for ease of maintenance, please refer to Figure 1The maintenance module 5 includes a trolley body 51, a transverse mechanism 52 and a spray mechanism 53. The transverse mechanism 52 is installed on the top of the trolley body 51. The movable end of the transverse mechanism 52 is connected to the spray mechanism 53 to drive the spray mechanism 53 to perform reciprocating spray maintenance along the axial direction of the tunnel. The trolley body 51 can move in the tunnel, and the transverse mechanism 52 is used for the spray mechanism 53 to perform reciprocating atomizing spray maintenance along the length direction of the tunnel. The spray mechanism 53 is composed of an arc-shaped bracket and atomizing nozzles evenly distributed thereon.

[0043] In one embodiment, to facilitate trench construction, refer to Figure 1 The groove template module 6 includes a walking body 61, a lifting mechanism 62 and a groove steel template 63. The lifting mechanism 62 is installed on both sides of the walking body 61. The groove steel template 63 is connected to the movable end of the lifting mechanism 62 one by one for groove casting and forming. The lifting mechanism 62 is used to lower the groove steel template 63 for casting and forming, and the lifting mechanism 62 is used to lift the groove steel template 63 for demoulding, which can improve the efficiency of groove construction.

During the construction of the steel arch frame, the steel arch frame is located in a first position state, in an inclined stacked state, and the suspension mechanism 12 is lifted from the first position state to the second position state by the lifting mechanism 11, so that the steel arch frame is equidistantly erected;

[0047] S3. In the second position state, the movable end of the walking mechanism 13 is connected to the suspension mechanism 12, and multiple steel arch frames are arranged equidistantly and fed toward the tunnel face at the same time until they are moved to the corresponding construction position, and subsequent construction is carried out in cooperation with manual labor.

[0048] Furthermore, the suspension mechanism 12 is composed of a lifting base 122 and a suspension frame 123. After the steel arch frame is installed and fixed, the lifting base 122 is lowered in height, and after being detached from the socket position of the steel arch frame, it can be detached from the steel arch frame after being driven by the walking mechanism 13 for translation, and then separated.

[0049] Furthermore, in the subsequent replenishment of the steel arch frame, after the steel arch frame is installed in an open area outside the tunnel with another transport suspension frame 123, it is directly transported to the heading face and hoisted onto the lifting base 122, so that the steel arch frame can be quickly replenished for the next batch of construction.
