The spacing between the four arched support members may be between 0 mm and 300 mm (0 mm and 300 mm inclusive).

Alternatively, the first and

second supports

200 and 300 are each a cylindrical structure having a circular cross section, and the diameters of the first and

second supports

200 and 300 can be appropriately reduced due to the arrangement of a plurality of arched support assemblies. The specific size of the diameters of the first and second supporting

members

200 and 300 may be designed according to the supporting strength, and may not be particularly limited herein.

It should be noted that, in the embodiment of the present application, taking the arched girder 100 as an inverted U-shaped structure as an example, two ends of the arched girder 100 are two free ends of the U-shaped structure.

In the embodiment of the present application, the second supporting member 300 of each arch supporting assembly is connected to the second base 500, which is equivalent to increase the contact area between the end of the second supporting member 300 far away from the arched girder 100 and the bottom plate, thereby being beneficial to preventing the supporting member of the arch structure from sinking, and simultaneously increasing the supporting strength of the whole arch structure, and facilitating the walking of the corresponding arch supporting device on the bottom plate.

Alternatively, each of the first chassis 400 and the second chassis 500 may be a flat, flat plate-shaped structure.

Optionally, in order to facilitate the transportation of the arch structure, the first base 400 is detachably connected to the first support 200, and the second base 500 is detachably connected to the second support 300. The specific detachable connection mode may be bolt connection, pin connection, or clamping, and this embodiment of the present application may not be specifically limited.

In some embodiments, with continued reference to fig. 1, the arched beam 100 of fig. 1 includes an arched beam body 130 and first and second side spars 110, 120 disposed at either end of the arched beam body 130. The first side spar 110 and the second side spar 120 serve as a guide structure for the arched beam 100, and are arranged in a vertical direction during actual operation.

One end (schematically, upper end in fig. 1) of the first side spar 110 is connected to one end of the arched girder body 130, and the other end (schematically, lower end in fig. 1) of the first side spar 110 is slidably connected to the first support 200; one end (schematically, an upper end in fig. 1) of the second side spar 120 is connected to the other end of the arched beam body 130, and the other end (schematically, a lower end in fig. 1) of the second side spar 120 is slidably connected to the second support member 300.

Specifically, the first side spar 110 and the second side spar 120 may be integrally connected with the arched beam 100 or detachably connected with the arched beam. Of course, for the convenience of disassembly and transportation, the first side wing beam 110, the arched beam 100, and the second side wing beam 120 may be detachably connected by means of clamping, sleeving, or bolting.

Alternatively, to further reduce the size of the arch structure, facilitating loading and transportation, a detachable connection between the first support 200 and the arched girder 100 may be used; and/or the second support 300 may be removably coupled to the arched beam 100.

In the embodiment of the present application, the first side spar 110 of the arched girder 100 serves as a guide component of the corresponding first support 200, and the second side spar 120 serves as a guide component of the second support 300, so that the arched girder body 130 can be free from the structural and dimensional constraints of the first side spar 110 and the second side spar 120, and the manufacture of the arched girder body 130 is facilitated.

In some embodiments, with reference to fig. 1, the first side wing beam 110 and the second side wing beam 120 are both hollow beams, the first side wing beam 110 is at least partially sleeved outside the first supporting member 200, and the second side wing beam 120 is at least partially sleeved outside the second supporting member 300.

It should be noted that the specific situation of the first side spar 110 at least partially sleeved outside the first support member 200 is determined by the length of the first side spar 110, the length of the first support member 200, and the lifting stroke of the first side spar 110.

Assuming that the length of the first side spar 110 is less than the length of the first support member 200, and the first side spar 110 slides up and down along the first support member 200 or the first support member 200 drives the first side spar 110 to slide, the first side spar 110 may be partially sleeved outside the first support member 200, and an end of the first support member 200 close to the bottom plate may be exposed. When the length of the first side spar 110 is greater than the length of the first support 200, the first side spar 110 may be completely nested when it is stroke down. In addition, the relationship between the second support 300 and the second side spar 120 can refer to the relationship between the first side spar 110 and the first support 200, and will not be described in detail herein.

In some embodiments, as shown in fig. 4, in order to further improve the structural stability of the arch structure, the arch structure in the embodiment of the present application includes a connector 600 in addition to the plurality of arch support assemblies; the lower portions of the plurality of arched support members are integrally connected by a connector 600.

Specifically, the connection member 600 may be connected to the first support member 200 of each arched support assembly, the second support member 300 of each arched support assembly, and the arched beam 100 of each arched support assembly, as long as the installation of the top beam 700 on the arched beam 100 is not affected. The connecting members 600 are arranged along the arrangement direction of the arch support assemblies, and when the arch structure is placed in the tunnel, the connecting members 600 are arranged along the length extension direction of the tunnel.

Alternatively, the number of the connecting members 600 may be one or more than one, and may be specifically set according to the requirement of the supporting strength of the arch structure. When the connecting member 600 is plural, the plural connecting members 600 may be provided at equal intervals, thereby integrating the arched girders 100, the first supporting members 200, and the second supporting members 300 in the arch structure. Of course, for the convenience of detachment, the connecting member 600 may be detachably connected to the arched girder 100, the first supporting member 200, or the second supporting member 300.

It should be noted that, for different arch frame structures of the same arch support device, the connecting members can be selectively arranged according to actual conditions because the support force requirements of the positions of the different arch frame structures are different. For example: for the arch structure at the position with larger supporting strength, the number of the arch support components of the arch structure can be properly increased, and meanwhile, the connecting pieces are added to connect all the arch support components of the arch structure so as to increase the stability of the arch structure; for the arch structure at the position with larger supporting force, the number of arch support groups can be properly reduced, and even the arch support groups can be reinforced without connecting pieces, so long as the supporting requirements are met. In the embodiment of the application, through setting up horizontal connecting piece 600, can connect each arch supporting component as an organic whole for whole bow member structure is more stable, is favorable to improving arch strutting arrangement and to the supporting effect of roof plate.

Specifically, for a plurality of arch support assemblies, each arch support assembly adopts the first support 200 and the second support 300 to guide and support the arched girder 100. The first supporting members 200 in the same arch structure may be a part of struts having a guiding function (only a guiding function is provided between the arched girder 100 and the first supporting members 200), and another part of struts having a lifting function is a linear driving device, and the linear driving device may drive the arched girder 100 to lift and lower and may support the arched girder 100 at any position. Of course, all the first supporting members 200 may be a lifting linear driving member, and may be selected according to actual supporting strength requirements.

Similarly, a plurality of second supporting members 300 in the same arch structure may have a guiding function (only guiding function between the arched girder 100 and the second supporting members 300) in one part, and a linear driving device having a lifting function in another part, and the linear driving device may drive the arched girder 100 to lift and lower and may support the arched girder 100 at any position. Of course, all the second supporting members 300 may be lifting linear driving members, and may be specifically selected according to actual supporting strength requirements. In the embodiment of the application, at least part of the first supporting piece 200 or the second supporting piece 300 is set to be a liftable linear driving part, so that the lifting adjustment of the arch structure can be facilitated, the number and the distribution mode of the linear driving parts can be reasonably selected according to the supporting requirement, and the manufacturing cost is saved.

Alternatively, the telescopic linear drive mechanism may be a hydraulic jack or an electric push rod. The supporting force of the hydraulic jack is large, the reaction speed of the electric push rod is high, and the electric push rod can be selected according to the supporting requirement of the top plate and is not particularly limited.
