[0003] The shield segments of existing shield tunnels are prefabricated with bolt connection holes along the circumferential direction and the axial direction of the shield segments. During the shield construction process, when adjacent shield segments are spliced ​​together, the adjacent shield segments can be connected as a whole to form the inner wall of the shield tunnel by inserting radial segment bolts into the bolt connection holes along the circumferential direction and axial segment bolts into the bolt connection holes along the axial direction.

[0059] like Figures 1 to 7 As shown, the utility model discloses a forced centering bracket for shield tunnel drilling-free measurement, and the bracket is arranged on the shield segment of the shield tunnel. The bracket includes:

[0060] An installation platform 1, wherein the installation platform 1 is configured to install a detection device;

[0061] A first connecting component 2, wherein the first connecting component 2 connects the mounting platform 1 to the shield segment;

[0062] A second connecting component 3, one end of which is connected to the shield segment; in the vertical direction, the horizontal height of the second connecting component 3 is less than the horizontal height of the first connecting component 2;

[0063] An adjusting component 4, one end of which is connected to an end of the mounting platform 1 away from the first connecting component 2, and the other end of which is connected to a side of the second connecting component 3 away from the shield segment;

[0064] The shield tunnel is provided with a connecting component 5 for connecting adjacent shield segments, and one end of the first connecting component 2 and the second connecting component 3 close to the connecting component 5 are respectively connected to the connecting component 5 in a cooperative manner.

[0065] In the utility model, the connection parts between the existing components are directly utilized, and there is no need to perform additional drilling on the pipe segment, thereby avoiding damage to the structural strength of the pipe segment; by setting the adjusting component 4, the horizontality of the installation platform 1 is adjusted through forced centering, thereby ensuring the consistency of the horizontality of the detection equipment installed on the installation platform 1 and ensuring the accuracy of the measurement information; by setting the first connecting component 2 and the second connecting component 3, more limited positions are provided for the bracket, making the installation of the bracket and the shield pipe segment more secure.

[0066] In a specific implementation of this embodiment, the connecting component 5 for connecting adjacent shield segments refers to a radial segment bolt that penetrates into the bolt connection holes in the circumferential direction of two adjacent shield segments in the circumferential direction. The first connecting component 2 and the second connecting component 3 are connected to the upper end and the lower end of the radial segment bolt (the upper end and the lower end here refer to the upper and lower ends of the radial segment bolt in the height direction).

[0067] In a specific implementation of this embodiment, the bracket is installed on the connecting component 5 of the shield segment at the waist position of the shield tunnel.

[0068] Please see attached Figure 1 To Attachment Figure 3 and attached Figure 5 In a specific implementation of this embodiment, the adjusting component 4 includes:

[0069] A first threaded rod 41, one end (non-threaded end) of the first threaded rod 41 is connected to the mounting platform 1, and the other end (threaded end) of the first threaded rod 41 is provided with an external thread structure with a rotation direction in a first direction;

[0070] An adjusting sleeve 42, wherein one end of the adjusting sleeve 42 close to the first threaded rod 41 is provided with an internal thread structure that matches with the external thread structure of the first threaded rod 41 in a first direction, and the other end of the adjusting sleeve 42 is provided with an internal thread structure in a second direction; the first direction and the second direction represent opposite directions of rotation;

[0071] The second threaded rod 43 has an external thread structure at one end thereof that matches the internal thread structure of the adjusting sleeve 42 that rotates in the second direction, and the other end of the second threaded rod 43 is connected to the second connecting assembly 3 .

[0072] In the present invention, the adjustment component 4 is provided to adjust the level of the installation platform 1, thereby ensuring that the detection equipment installed on the installation platform 1 is in a forced centering state, so that the level of multiple adjacent detection equipment corresponds to each other.

[0073] In a specific implementation of this embodiment, the first direction refers to left-hand rotation, and the second direction refers to right-hand rotation.

[0074] In a specific implementation of this embodiment, the first direction refers to right-hand rotation, and the second direction refers to left-hand rotation.

[0075] When in use, the end of the first threaded rod 41 away from the mounting platform 1 rotates and extends into the adjustment sleeve 42 (the end rotated to adapt), and the end of the second threaded rod 43 away from the second connecting assembly 3 rotates and extends into the adjustment sleeve 42 (the side rotated to adapt).

[0076] In a specific implementation of this embodiment, the first direction of rotation is left-handed, and the second direction of rotation is right-handed. When the adjusting sleeve 42 is rotated clockwise, the first threaded rod 41 moves in a direction away from the adjusting sleeve 42 (the threaded end of the first threaded rod 41 gradually detaches from the adjusting sleeve 42 as the adjusting sleeve 42 rotates), and the second threaded rod 43 moves in a direction away from the adjusting sleeve 42 (the threaded end of the second threaded rod 43 gradually detaches from the adjusting sleeve 42 as the adjusting sleeve 42 rotates), so that the length of the adjusting component 4 increases; when the adjusting sleeve 42 is rotated counterclockwise, the first threaded rod 41 moves in a direction close to the adjusting sleeve 42 (the threaded end of the first threaded rod 41 gradually turns into the adjusting sleeve 42 as the adjusting sleeve 42 rotates), and the second threaded rod 43 moves in a direction close to the adjusting sleeve 42 (the threaded end of the second threaded rod 43 gradually turns into the adjusting sleeve 42 as the adjusting sleeve 42 rotates), so that the length of the adjusting component 4 decreases.

[0077] In another specific implementation of this embodiment, the first direction of rotation is right-handed, and the second direction of rotation is left-handed. When the adjusting sleeve 42 is rotated clockwise, the first threaded rod 41 moves toward the direction close to the adjusting sleeve 42 (the threaded end of the first threaded rod 41 gradually turns more into the adjusting sleeve 42 as the adjusting sleeve 42 rotates), and the second threaded rod 43 moves toward the direction close to the adjusting sleeve 42 (the threaded end of the second threaded rod 43 gradually turns more into the adjusting sleeve 42 as the adjusting sleeve 42 rotates), so that the length of the adjusting component 4 is reduced; when the adjusting sleeve 42 is rotated counterclockwise, the first threaded rod 41 moves toward the direction away from the adjusting sleeve 42 (the threaded end of the first threaded rod 41 gradually detaches more from the adjusting sleeve 42 as the adjusting sleeve 42 rotates), and the second threaded rod 43 moves toward the direction away from the adjusting sleeve 42 (the threaded end of the second threaded rod 43 gradually detaches more from the adjusting sleeve 42 as the adjusting sleeve 42 rotates), so that the length of the adjusting component 4 is increased.

[0078] Please see attached Figure 3 and attached Figure 5 In a specific implementation of this embodiment, the adjusting component 4 further includes: a stop nut 44, and the stop nut 44 is arranged on the first threaded rod 41 and / or the second threaded rod 43.

[0079] After the adjusting component 4 is adjusted to a specified length by rotating the adjusting sleeve 42 , the stop nut 44 provided on the first threaded rod 41 and / or the second threaded rod 43 is rotated toward the direction approaching the adjusting sleeve 42 , and finally rotated until it contacts the adjusting sleeve 42 .

[0080] In the utility model, the stop nut 44 is provided to limit the rotation of the adjusting sleeve 42 relative to the first threaded rod 41 and the second threaded rod 43, so that the length of the adjusting component 4 adjusted to a specified length is locked (the stop nut 44 is rotated toward the side close to the adjusting sleeve 42 until it is rotated and attached to the adjusting sleeve 42), thereby avoiding the problem of causing the horizontality of the mounting platform 1 to change.

[0081] It is understandable that, by rotating the adjusting sleeve 42, the first threaded rod 41 and the second threaded rod 43 will move toward or away from the adjusting sleeve 42 to change the length of the adjusting component 4. When the length adjustment is completed, the above-mentioned stop nut 44 is provided to avoid sliding. The rotation of the first threaded rod 41 and the second threaded rod 43 is synchronous, so in principle, the length locking effect can be achieved by limiting the movement of one of the rods (providing the stop nut 44 on the first threaded rod 41 or the second threaded rod 43). Of course, to further avoid sliding, the stop nut 44 can be provided on both the first threaded rod 41 and the second threaded rod 43.

[0082] Please see attached Figure 3 and attached Figure 4 In a specific implementation of this embodiment, the installation platform 1 includes:

[0083] The platform body 11 is composed of a rectangular plate 111 and a semicircular plate 112 which are connected to each other and have the same thickness, and the width of the rectangular plate 111 is equal to the diameter of the semicircular plate 112;

[0097] In another specific implementation of this embodiment, the distance between the two vertical walls 211 is greater than the distance between the two first connection positions 12, that is, the first connection position 12 is arranged on the inner side of the vertical wall 211 (the two first connection positions 12 are arranged between the two vertical walls 211).

[0098] In another specific implementation of this embodiment, the distance between the two vertical walls 211 is equal to the distance between the two first connection positions 12, that is, one of the two first connection positions 12 is arranged on the inner side of the vertical wall 211, and the other of the two first connection positions 12 is arranged on the outer side of the vertical wall 211 (the first connection positions 12 and the vertical wall 211 are arranged in sequence at intervals).

[0100] A first rod hole 411 is provided at one end (non-threaded end) of the first threaded rod 41 close to the second connection position 13;

[0104] In another specific implementation of this embodiment, two adjusting components 4 are provided, and two second connecting positions 13 are also provided. The first threaded rods 41 (non-threaded ends) of the two adjusting components 4 are connected to different second connecting positions 13 .

[0105] Please see attached Figure 1 To Attachment Figure 3 and attached Figure 7 In a specific implementation of this embodiment, the second connection component 3 includes:

[0106] The second connecting part 31 is a "U-shaped" structural member; the second connecting part 31 includes a connecting wall 314 and two end walls 311 connected to the two ends of the connecting wall 314; the end wall 311 is provided with a second matching hole 312, and the second threaded rod 43 is provided with a second rod hole 431 at one end (non-threaded end) close to the second connecting component 3; the third connecting bolt 313 is provided to pass through the second matching hole 312 and the second rod hole 431, so as to connect one end of the second threaded rod 43 to the second connecting component 3;

[0108] It should be pointed out that when two second connection positions 13 are provided at the bottom of the installation platform 1, the second connection component 3 is substantially identical to the first connection component 2 in structure, and the end wall 311 is vertically provided on the connection wall 314, and the two end walls 311 extend in the same direction, that is, the end wall 311 of the second connection component 3 is substantially parallel to the vertical wall 211 of the first connection component 2. However, the inclination angle of the first fixing portion 22 of the first connection component 2 relative to the flat wall 213 and the inclination angle of the second fixing portion 32 of the second connection component 3 relative to the connection wall 314 are different in size and direction.
