[0042] Compared with the prior art, the advantages of the present invention are:

[0043] For the reinforcement of shield tunnels, the main existing patent methods include: internal steel ring reinforcement method, fiber board pasting method, and composite cavity method. Compared with the reinforcement method proposed by the present invention, this method has the following advantages:

[0044] During reinforcement, it can quickly respond to the position that needs to be reinforced, and is more convenient to implement than the internal steel ring reinforcement method.

[0045] Compared with the fiber paste reinforcement method, this reinforcement method can improve the overall strength of the segment and is not easily affected by fires like the fiber paste method.

[0046] Compared with the composite cavity method, the existing segment production already has a considerable scale. This method applies reinforcement measures on the existing segments, with a simple structure, high flexibility, and does not require re - designing the segment structure.

[0047] (4) The designed inner chute structure of the device can well adapt to the reinforcement of segments with different distances between manhole positions.

[0048] (5) This reinforcement method can effectively deal with the segment deformation problems at different positions. Description of the Drawings

Embodiment

[0061] The rapid reinforcement device and method for shield tunnel structure of the present invention will be described in more detail below with reference to the schematic diagrams, in which the preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present invention. Embodiment

[0062] A rapid reinforcement device for shield tunnel structure, which is used in shield tunnels. This device can reinforce the deformed shield tunnel structure, that is, rely on the overall structure of the manhole and the original bolts on the manhole to provide the position for applying force, so as to effectively improve the overall safety of the shield tunnel during operation.

[0063] Such as Figures 1 - 6 , specifically, the device includes:

[0064] The first reinforcing body 1 and the second reinforcing body 3 are both used to connect two adjacent segments of a ring of segments. The outer ring surfaces of the first reinforcing body 1 and the second reinforcing body 3 are both attached to the inner ring surface of the segment, that is, the first reinforcing body 1 and the second reinforcing body 3 have the same radius as the segment to ensure sufficient contact with the inner diameter of the segment; each segment has multiple manholes for fixing the segment.

[0065] Both the first reinforcing body 1 and the second reinforcing body 3 are of a hollow structure.

[0066] On the outer ring surfaces of both the first solid addition member 1 and the second solid addition member 3, an inner sliding groove 11 extending along the circumferential direction is provided, and both ends of the inner sliding groove 11 are open along the circumferential direction.

[0067] At the same end along the circumferential direction, the inner sliding groove 11 on the first solid addition member 1 and the inner sliding groove 11 on the second solid addition member 3 are respectively engaged with a first sliding block 5; at the other end along the circumferential direction, the inner sliding groove 11 on the first solid addition member 1 and the inner sliding groove 11 on the second solid addition member 3 are respectively engaged with a second sliding block 6, and the outer ring surfaces of the first sliding block 5 and the second sliding block 6 are both located outside the inner sliding groove 11. For example, the outer ring surface of the first sliding block 5 is the outer ring surface 52 of the first sliding block.

[0068] When the first sliding block 5 and the second sliding block 6 are engaged with the inner sliding groove, the sliding rails (for example, as shown in Figure 4 , 6 ), where the sliding rail on the first sliding block 5 is formed by a protrusion 51) for engaging the first sliding block 5 and the second sliding block 6 with the first solid addition member 1 and the second solid addition member 3 respectively are used to determine the positions of the hand holes on adjacent segments, ensuring that the fixing block 7 can be engaged with the hand holes of the segments.

[0069] On the inner ring surfaces of both the first solid addition member 1 and the second solid addition member 3, bolt holes 12 for connecting the first sliding block 5 and bolt holes 12 for connecting the second sliding block 6 are provided.

[0070] A rack 8 and a bracket 9, the rack 8 is arranged on the inner ring surface of the first sliding block 5; the bracket 9 is detachably arranged on the first solid addition member 1 and the second solid addition member 3, and a driving unit for driving the rack 8 is arranged on the bracket 9; the driving unit can be temporarily reinforced on the bracket 9. Along the circumferential direction, after the cooperation between the shield tunnel structure rapid reinforcement device and the segment is tightened and sufficient pre-tightening force is provided, the bolts corresponding to the first sliding block 5 are tightened, and the bracket 9 can be disassembled for other uses.

[0071] A distance adjusting unit can flexibly adjust the distance between the first solid addition member 1 and the second solid addition member 3 to better adapt to various types of segments. Specifically, it includes a first sleeve 2 and a second sleeve extending along the longitudinal direction; wherein: the first sleeve 2 is a hollow structure, one end of the first sleeve 2 is fixed to the side surface of the first solid addition member 1, this side surface connects the inner ring surface and the outer ring surface of the first solid addition member 1, and the other end forms an open end to insert the second sleeve into the first sleeve 2;

[0072] One end of the second sleeve is fixed to the side surface of the second solid addition member 3, and this side surface connects the inner ring surface and the outer ring surface of the second solid addition member 3;

[0073] The fixing block 7 is used to fix the rapid strengthening device of the shield tunnel structure on the segment. Fixing blocks 7 are arranged on the outer ring surfaces of the first slider 5 and the second slider 6. An installation hole matching the hand hole on the segment is opened on the fixing block 7, and it is in full contact and cooperation with the hand hole.

[0074] Wherein, the driving unit is a gear, the gear is rotatably arranged on the corresponding bracket 9, and the gear meshes with the rack 8 on the corresponding first slider 5.

[0075] A clamping strip 71 is arranged on the installation surface of the fixing block 7 facing away from the hand hole (segment). A screw hole is opened on the clamping strip 71 for fixing the fixing block 7 on the outer ring surface of the first slider 5 or the second slider 6, as Figure 6 shown.

[0076] The working principle of the rapid strengthening device for the shield tunnel structure for connecting the 1# ring segment:

[0077] Step 1: Adjust the distance L1 between the first sleeve 2 and the second sleeve so that the strengthening device is completely located on the 1# ring segment.

[0078] Step 2: Install a first slider 5 in the inner sliding groove 11 on the first reinforcing body 1, and install another first slider 5 in the inner sliding groove 11 on the second reinforcing body 3.

[0079] At the same time, install a second slider 6 in the inner sliding groove 11 on the first reinforcing body 1, and install another second slider 6 in the inner sliding groove 11 on the second reinforcing body 3.

[0080] Use bolts to fix the two second sliders 6 on the first reinforcing body 1 and the second reinforcing body 3 respectively.

[0081] Step 3: Fix the fixing blocks 7 on the first slider 5 and the second slider 6 through the clamping strip 71 and screws respectively. Specifically, the circular holes on the fixing block 7 are aligned with the bolt positions in the segment hand hole, and the circular holes can enclose the nuts of the bolt structure; the clamping strip 71 is used to cooperate with the grooves on the sliders (the first slider 5, the second slider 6), as Figure 6 shown.

[0082] Step 4: The fixing block 7 on the second slider 6 is clamped on the bolt at the corresponding hand hole through the screw hole on it.

[0083] Step 5: The driving unit drives the rack 8 to move, so that the two first sliders 5 are tightened to the corresponding sliding grooves 11. At this time, the second slider 6 remains stationary.

[0084] When the circumferential spacing C1 between the two fixing blocks 7 on the first solidifying body 1 corresponds to the circumferential spacing C2 between different hand holes on two adjacent segments (segment 1#1 and segment 1#2), and the circumferential spacing C11 between the two fixing blocks 7 on the second solidifying body 3 corresponds to the circumferential spacing C21 between different hand holes on two adjacent segments (segment 1#1 and segment 1#2), the driving unit stops working.

[0085] At this time, bolt the two first sliders 5 to the first solidifying body 1 and the second solidifying body 3 respectively.

[0086] At this time, the knot support 9 and the driving unit can be disassembled, so as to reduce the occupation of the space in the tunnel by the reinforcement device.

[0087] Step 6: Clamp the fixing block 7 on the second slider onto the bolt at the corresponding hand hole of the segment through the screw hole thereon. Embodiment

[0088] As Figures 7 - 9 shown, on the basis of Embodiment 1, the fixing block 7 is further designed so that the direction of the fixing block 7 is adjustable.

[0089] As Figure 7 shown, the mounting surface of the fixing block 7 facing away from the hand hole (segment) is detachably connected to a flange 10. A clamping strip 71 is provided on the mounting surface of the flange 10 facing the segment, and screw holes are provided on the clamping strip 71 for fixing the fixing block 7 to the outer ring surface of the first slider 5 or the second slider 6.

[0090] Working principle:

[0091] Step 1: Rotate the fixing block 7 to adjust the direction of the fixing block 7, and then fix the fixing block 7 to the flange 10.

[0092] Step 2: Adjust the distance L1 between the first sleeve 2 and the second sleeve so that the reinforcement device is completely located on the 1# ring segment.

[0093] The subsequent steps are the same as those in Embodiment 1. Embodiment

[0094] On the basis of Embodiment 2, as Figures 10 - 11 shown, the rapid reinforcement device for shield tunnel structure is used to connect two rings of segments (including 1# ring segment and 2# ring segment), and its working principle is as follows:

[0095] Step 1: Rotate the fixing block 7 to adjust the direction of the fixing block 7, and then fix the fixing block 7 to the flange 10.

[0096] Step 2: Adjust the distance L1 between the first sleeve 2 and the second sleeve so that the first reinforcing member 1 of the reinforcement device is located on the inner ring surface of the 1# segment ring, and the second reinforcing member 3 is located on the inner ring surface of the 2# segment ring.

[0097] Step 3: Install a first slider 5 in the inner chute 11 on the first reinforcing member 1, and install another first slider 5 in the inner chute 11 on the second reinforcing member 3.

[0098] At the same time, install a second slider 6 in the inner chute 11 on the first reinforcing member 1, and install another second slider 6 in the inner chute 11 on the second reinforcing member 3.

[0099] Fix the two second sliders 6 to the first reinforcing member 1 and the second reinforcing member 3 respectively with bolts.

[0100] Step 4: Fix the fixing block 7 to the first slider 5 and the second slider 6 through the clamping strip 71. Specifically, the circular hole on the fixing block 7 is aligned with the position of the bolt in the segment hand hole, and the circular hole can enclose the nut of the bolt structure; the clamping strip 71 is used to cooperate with the groove on the slider (the first slider 5, the second slider 6).

[0101] Step 5: Fix the fixing block 7 on the second slider 6 to the corresponding hand hole through the screw hole on it.

[0102] Step 6: The driving unit drives the rack 8 to move so that the two first sliders 5 are tightened to the corresponding chutes 11.

[0103] When the circumferential spacing C1 between the two fixing blocks 7 on the first reinforcing member 1 corresponds to the circumferential spacing C2 between different hand holes on two adjacent segments (the 1#1 segment and the 1#2 segment), and the circumferential spacing C11 between the two fixing blocks 7 on the second reinforcing member 3 corresponds to the circumferential spacing C21 between different hand holes on two adjacent segments (the 2#1 segment and the 2#2 segment), the driving unit stops working.

[0104] At this time, fix the two first sliders 5 to the first reinforcing member 1 and the second reinforcing member 3 respectively with bolts.

[0105] At this time, the connection bracket 9 and the driving unit can be disassembled, so as to reduce the occupation of the space in the tunnel by the reinforcement device.

[0106] Step 7: Clamp the fixing block 7 on the second slider 5 to the bolt at the corresponding hand hole of the segment through the screw hole on it.

[0107] The above are only the preferred embodiments of the present invention and do not impose any restrictive effect on the present invention. Any person skilled in the art, within the scope of the technical solution of the present invention, makes any form of equivalent substitution or modification and other changes to the technical solution and technical content disclosed by the present invention, which are all within the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
