[0001] The present invention relates to the technical field of tunnel construction, and in particular to a soft rock tunnel excavation method, device, equipment, system and medium. Background Art

[0002] Soft rock tunnel refers to a tunnel structure formed in a soft rock geological body. When tunnel excavation and tunneling construction are carried out in a soft rock geological body, over-excavation may occur. Over-excavation will increase the amount of slag discharge, increase the thickness of the initial shotcrete, delay the construction period and increase the construction cost. If the over-excavation is not properly controlled, cavities and unstable surrounding rock will easily form behind the initial support. In order to reduce the amount of over-excavation, the external insertion angle of the drill hole is generally reduced while the opening position is converged to reduce over-excavation. There will be under-excavation near the supported steel frame section, and the under-excavation treatment takes a long time, affecting the progress and quality of the project.

[0003] In the prior art, when excavating soft rock tunnels, controlled blasting and milling are usually used for excavation. However, due to the weak characteristics of soft rock, over-excavation or under-excavation occurs during the actual construction process, which affects the construction efficiency and forming quality of the tunnel.

[0055] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0056] See also Figures 1 to 9 The present application proposes a first embodiment of a soft rock tunnel excavation method, comprising the following steps:

[0057] S100, when using a preset milling device to perform a milling operation on the soft rock in the target construction area, using a preset scanning device to perform a scanning operation on the target construction area to obtain a current tunnel profile formed in the target construction area;

[0058] In this embodiment, when implemented specifically, the preset scanning device of the example includes the following structure:

[0059] The positioning mechanism 100 includes a first connecting member 110, one end of which is connected to the milling device, and the other end of the first connecting member 110 extends toward the target construction area and forms a mounting hole, in which a first laser transceiver 120 is installed, and the first laser transceiver 120 is communicatively connected to the soft rock tunnel excavation device, and the first laser transceiver 120 can emit a positioning beam to a preset center position;

[0060] The rotating mechanism 200 includes a driving member 210, which is mounted on the first connecting member 110. A driving gear 220 is mounted on the output end of the first connecting member 110. The driving gear 220 is meshed with a gear ring 230 sleeved on the outer periphery of the first connecting member 110. A guide member 240 is provided on the first connecting member 110 to slide with the side of the gear ring 230. A mounting position 250 is formed on the side wall of the gear ring 230 away from the first connecting member 110; and,

[0061] The scanning mechanism 300 includes a first telescopic driving member 310210 and a second telescopic driving member 320210. The first telescopic driving member 310210 and the second telescopic driving member 320210 are spaced apart at the mounting position 250 along the extension direction of the first connecting member 110. The first telescopic member and the second telescopic member are both hinged to the mounting position 250, and the telescopic ends of the first telescopic member and the second telescopic member are both connected to a second connecting member 330. The second connecting member 330 extends along the extension direction of the first connecting member 110, and an installation groove is formed at one end of the second connecting member 330 toward the target construction area. A scanner 340 is installed in the installation groove. The first telescopic member and / or the second telescopic member can drive the second connecting member 330 to approach or move away from the first connecting member 110 to adjust the scanning direction of the scanner 340.

[0062] In this embodiment, by setting a positioning mechanism 100, a rotating mechanism 200 and a scanning mechanism 300, when in use, the ring gear 230 in the rotating mechanism 200 is sleeved on the outer periphery of the first connecting member 110, and the driving member 210 installed on the outer periphery of the first connecting member 110 drives the ring gear 230 to rotate through the driving gear 220, thereby realizing the function of adjusting the scanning direction of the scanning mechanism 300. At the same time, the second connecting member 330 is driven by the cooperation of the first telescopic member and / or the second telescopic member, thereby realizing the function of adjusting the scanning angle of the scanner 340. Finally, the present invention can use the scanner 340 to realize the function of real-time scanning of different working positions in different target working areas during actual operation.

[0063] It needs to be further explained that, in this embodiment, during the specific implementation, the scanner 340 can also follow the milling equipment to perform the following operation, thereby enabling the present invention to instantly follow and complete the scanning operation when the milling equipment is milling, so that during the actual operation, the present invention can instantly generate the quality of the current tunnel profile formed by the milling equipment operation.

[0064] It should be particularly and clearly stated that, in this embodiment, the exemplified laser transceiver and scanner 340 use existing technologies, and this application does not make any improved designs therefor, so their structures and working principles will not be described in detail here.

[0065] S200, determining whether the current tunnel profile coincides with a preset tunnel profile;

[0066] In this embodiment, when determining whether the current tunnel profile coincides with the preset tunnel profile, positioning can be performed based on the preset center position that has been set, and then the preset center position is simultaneously projected to the current tunnel profile and the preset tunnel profile, so that the same positioning point exists between the current tunnel profile and the preset tunnel profile, and finally the present invention can accurately determine whether the current tunnel profile coincides with the preset tunnel profile. Of course, in order to more clearly determine whether the current tunnel profile coincides with the preset tunnel profile, in specific implementation, at least two auxiliary positioning positions can also be set in the target construction area. During the scanning operation, at least two auxiliary positioning positions and the preset center position are projected to the current tunnel profile and the preset tunnel profile, so as to achieve the purpose of comparing whether the current tunnel profile coincides with the preset tunnel profile.

[0067] S300. When there is overlap, the process returns to the step of using a preset scanning device to scan the target construction area while using a preset milling device to perform milling operations on the soft rock in the target construction area to obtain a current tunnel profile formed in the target construction area until the tunnel is formed.

[0068] In this embodiment, when using a preset milling device to perform milling operations on the soft rock in the target construction area, a preset scanning device is used to perform a scanning operation on the target construction area to obtain a current tunnel contour formed in the target construction area, and it is determined whether the current tunnel contour coincides with the preset tunnel contour. If so, the process returns to executing the step of scanning the target construction area using a preset scanning device to perform milling operations on the soft rock in the target construction area to obtain a current tunnel contour formed in the target construction area until a tunnel is formed. When in use, when performing a milling operation, it is determined whether to continue excavating the soft rock tunnel according to the degree of overlap between the current tunnel contour obtained by scanning the target construction area and the preset tunnel contour. This allows the present invention to avoid the defects of poor forming quality and the impact on tunnel construction efficiency due to over-excavation or under-excavation caused by the surrounding rock characteristics of the soft surrounding rock tunnel, thereby achieving the purpose of efficient tunnel excavation.

[0069] In one embodiment, after step S200, the method further includes:

[0070] S400, when there is no overlap, intercepting the non-overlapping area between the current tunnel outline and the preset tunnel outline to form a current outline;

[0071] S500, determining the reason for the non-overlap between the current profile and the preset tunnel profile according to the coordinate position relationship between the current profile and the preset tunnel profile; wherein the non-overlap reason includes an over-break operation reason and an under-break operation reason;

[0072] In this embodiment, when determining the cause of the non-overlap, a judgment can be made based on the projection result of the current tunnel contour on the preset tunnel contour. When the current tunnel contour is projected on the preset tunnel contour and part of it is located outside the preset tunnel contour, it indicates that the area outside the preset tunnel contour is an over-excavation area, that is, the non-overlap in this area is caused by over-excavation; when the current tunnel contour is within the preset tunnel contour, it indicates that the area is an under-excavation area, that is, the non-overlap in this area is caused by under-excavation.

[0073] S600, establishing a treatment plan for the current contour according to the acquired non-overlapping reason; wherein the treatment plan includes: when the non-overlapping reason is the over-excavation operation, the treatment plan is to perform a filling operation on the area where the current contour is located; when the non-overlapping reason is the under-excavation operation, the treatment plan is to perform a secondary milling operation on the current contour;

[0074] S700: Perform a treatment operation on the current contour using the treatment plan until the current contour is eliminated and the current tunnel contour is made to coincide with the preset tunnel contour.

[0075] In this embodiment, by processing non-overlapping areas in real time, the present invention can timely process existing over-break or under-break areas during tunnel construction, thereby avoiding the impact of over-break or under-break on the tunnel line shape.

[0076] In one embodiment, before step S300, the method further includes:

[0077] S800, determining a preset center position of the soft rock tunnel according to preset construction data;

[0078] Step S400 includes:

[0079] S410: When they do not overlap, projecting the preset center position onto the current tunnel outline and the preset tunnel outline respectively to form a corresponding virtual positioning point;

[0080] S420: Overlap the two virtual positioning points, and intercept the non-overlapping areas between the current tunnel outline and the preset tunnel outline to form a current outline.

[0081] In one embodiment, after step S420, the method further includes:

[0082] S430: Output the non-overlapping reason corresponding to the current contour and perform an alarm operation.

[0083] In one embodiment, before step S100, the method further includes:

[0084] S10, using the preset scanning device to calibrate the preset tunnel profile in the target construction area;

[0085] S20, controlling the preset milling equipment to perform milling operations in the target construction area according to the preset tunnel profile.

[0086] Based on the same technical concept, in a second aspect, the present invention also proposes a soft rock tunnel excavation device, comprising:

[0088] A judging module, used to judge whether the current tunnel profile coincides with a preset tunnel profile;

[0089] The result output module is used to return to the step of using a preset scanning device to scan the target construction area when the preset milling equipment is used to perform milling operations on the soft rock in the target construction area to obtain the current tunnel contour formed in the target construction area, until the tunnel is formed.
