The seismic response of above-ground structures mainly depends on the dynamic characteristics of the structure itself, while the dynamic characteristics of underground structures themselves are suppressed, and their seismic response mainly depends on the deformation of the surrounding soil.

The assembled structure also includes: a clamp, which is used to connect to the top of the shield tunnel, and the clamp has a clamping space and a fastening member. The clamping space extends along the length direction of the prefabricated bottom bin, and the clamping space is used to accommodate the second end of the prefabricated middle partition wall. The fastening member has a locking position that extends into the clamping space to abut against the side wall of the prefabricated middle partition wall, and has an unlocking position that is located outside the clamping space to disengage from the side wall of the prefabricated middle partition wall.

[0011] Furthermore, both ends of the prefabricated middle partition wall are wrapped with flexible materials, the first end of the prefabricated middle partition wall abuts against the first connecting surface through the flexible material, and the second end of the prefabricated middle partition wall abuts against the fastening member through the flexible material.

[0012] Furthermore, the first connecting surface is an arc-shaped surface, the second connecting surface is a plane, and an avoidance cut surface is provided between the first connecting surface and the second connecting surface.

[0013] According to another aspect of the present invention, there is provided a method for assembling an assembly component, wherein the assembly component is the above-mentioned assembly component, and the assembly method is used to assemble the assembly component into the interior of a shield tunnel, and the assembly method comprises: placing a bag on the first connecting surface of a prefabricated bottom bin; moving the prefabricated bottom bin into the shield tunnel, and adjusting the position of the prefabricated bottom bin so that there is a preset gap between the first connecting surface and the inner wall of the shield tunnel; injecting a flexible grouting material into the bag so that the bag abuts against the inner wall of the shield tunnel; and connecting a prefabricated center partition wall between the second connecting surface of the prefabricated bottom bin and the top of the shield tunnel.

It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0036] Example 1

[0037] Combination Figures 1 to 6As shown, according to a specific embodiment of the present application, an assembly component for use inside a shield tunnel 4 is provided.

[0038] like Figure 1 As shown, the assembly components used inside the shield tunnel 4 include: a prefabricated bottom bin 1, a bag 2 and a prefabricated middle partition wall 3. The prefabricated bottom bin 1 has a first connecting surface 11 and a second connecting surface 12, the bag 2 is connected to the first connecting surface 11, the bag 2 is used to hold a flexible grouting material 21, and the prefabricated middle partition wall 3 is detachably connected to the second connecting surface 12. After grouting, part of the bag 2 extends outside the first connecting surface 11 and abuts against the inner wall of the shield tunnel 4, so that the first connecting surface 11 and the inner wall of the shield tunnel 4 have a preset gap, the elastic modulus of the flexible grouting material 21 after hardening is E1, the elastic modulus of the prefabricated bottom bin 1 is E2, E1≤E2, and the second connecting surface 12 of the prefabricated bottom bin 1 is connected to the top of the shield tunnel 4 through the prefabricated middle partition wall 3.

[0039] In an embodiment of the present application, part of the bag 2 after grouting is in contact with the inner wall of the shield tunnel 4, and there is a preset gap between the first connecting surface 11 and the inner wall of the shield tunnel 4, that is, the prefabricated bottom bin 1 is in flexibly contact with the inner wall of the shield tunnel 4 through multiple equivalent points or multiple equivalent lines, and a deformation space is formed between adjacent equivalent points. The elastic modulus of the flexible grouting material 21 after hardening is less than or equal to the elastic modulus of the prefabricated bottom bin 1. Under the action of an earthquake, the flexible grouting material 21 in the bag 2 is deformed before the prefabricated bottom bin 1 to absorb part of the seismic deformation, thereby reducing the seismic deformation transmitted to the prefabricated bottom bin 1. The assembly component has the ability to absorb seismic deformation, that is, the influence of the constraints of the shield tunnel 4 on the seismic response of the above-mentioned assembly component is reduced, and the seismic resistance of the assembly component is improved.

[0040] It is understandable that the prefabricated bottom silo 1 is a reinforced concrete prefabricated component, which can be an integral prefabricated component or assembled from multiple prefabricated components. The bladder bag 2 is a lightweight thin-walled bladder, which is used together with the flexible grouting material 21. The bladder bag 2 after grouting is sealed and leak-proof, and can withstand strong grouting pressure. During grouting, the flexible grouting material 21 is a fluid. After standing for a certain period of time, the flexible grouting material 21 gradually hardens and does not shrink after hardening. The hardened flexible grouting material 21 is in the shape of dots or strips. Among them, the flexible grouting material 21 can be materials such as rubber concrete or modified polymers.

[0041] It should be noted that if Figure 3 , Figure 5 As shown, the inner wall of the shield tunnel 4 is formed by splicing a plurality of shield segments 41, and there is a splicing misalignment between adjacent shield segments 41, that is, there is a position difference between the shield segments 41. During grouting, the flexible grouting material 21 is a fluid, and the liquid flexible grouting material 21 can adapt to the splicing misalignment and compensate for the position difference so that the bag 2 and the segment are seamlessly connected.

[0042] Furthermore, there are multiple bags 2, which are distributed on the first connecting surface 11 at intervals, and the rigidity of the flexible grouting material 21 in different bags 2 after hardening is different. Figure 1 , Figure 2 , Figure 4 As shown, there are five pouches 2 , and the five pouches 2 are arranged at intervals along the circumference of the first connecting surface 11 .

[0043] It should be noted that, in addition to absorbing earthquake deformation, the hardened flexible grouting material 21 also needs to support the prefabricated bottom bin 1. The earthquake effect on each point on the first connecting surface 11 has a different specific gravity, that is, the shear force on the hardened flexible grouting material 21 at each point is different, and the stiffness of the hardened flexible grouting material 21 at each point is different to avoid the grouting bag 2 at a certain point from breaking before the bag 2 at other positions.

[0044] Furthermore, the first connecting surface 11 is an arc-shaped surface, and a first bag 2 is provided at the lowest point of the first connecting surface 11. The stiffness of the flexible grouting material 21 in the first bag 2 after hardening is EI1, and the stiffness of the flexible grouting material 21 in other bags 2 except the first bag 2 after hardening is EI2, and EI1>EI2.

[0045] It should be noted that the horizontal seismic action has the greatest impact on the seismic response of the assembly components. The first bag 2 at the lowest point of the first connecting surface 11 vertically supports the prefabricated bottom bin 1. The shear force applied to the first bag 2 is greater than that applied to the bags 2 at other positions. Therefore, the stiffness EI1 is greater than the stiffness EI2 to avoid the first bag 2 after grouting from breaking before the bags 2 at other positions.

[0046] Furthermore, the first connecting surface 11 is provided with a first groove 13, and the bag 2 is connected to the inner wall of the first groove 13. The first groove 13 is provided to limit the position of the bag 2 after grouting, so as to limit the contact area between the bag 2 and the inner wall of the shield tunnel 4. Part of the bag 2 after grouting needs to extend outward from the first groove 13, that is, the height of the bag 2 after grouting is greater than the depth of the first groove 13, so that a preset gap is formed between the prefabricated bottom bin 1 and the inner wall of the shield tunnel 4.

[0047] Furthermore, the second connecting surface 12 is provided with a second groove 14, which is extended along the length direction of the prefabricated bottom bin 1, and the first end of the prefabricated middle partition wall 3 is plugged into the second groove 14. The assembled structure also includes a clamp 5, which is used to connect to the top of the shield tunnel 4. The clamp 5 has a clamping space 52 and a fastening member 53. The clamping space 52 extends along the length direction of the prefabricated bottom bin 1, and the clamping space 52 is used to accommodate the second end of the prefabricated middle partition wall 3. The fastening member 53 has a locking position extending into the clamping space 52 to abut against the side wall of the prefabricated middle partition wall 3, and has an unlocking position located outside the clamping space 52 to disengage from the side wall of the prefabricated middle partition wall 3.

[0048] In the embodiments of the present application, Figure 6 As shown, the clamp 5 includes two connecting plates 51 and two abutting members 53. The connecting plates 51 are L-shaped plates. Both connecting plates 51 are connected to the top wall of the shield tunnel 4. The two connecting plates 51 are arranged at intervals. The two connecting plates 51 and the top wall of the shield tunnel 4 are enclosed together to form a clamping space 52. Specifically, the connecting plates 51 have a first supporting side and a second supporting side arranged vertically. The first supporting side of the connecting plates 51 is connected to the top wall of the shield tunnel 4, and the abutting members 53 are threadedly connected to the first supporting side of the connecting plates 51. During the splicing process, the prefabricated middle partition wall 3 is inserted into the second groove 14 and the clamping space 52 at the same time, and the abutting members 53 are screwed inward to abut against the side walls of the prefabricated middle partition wall 3, that is, both sides of the prefabricated middle partition wall 3 abut against the abutting members 53.

[0049] As an alternative embodiment, the clamp 5 includes two connecting plates 51 and a fastening member 53. The connecting plates 51 are L-shaped plates. Both connecting plates 51 are connected to the top wall of the shield tunnel 4. The two connecting plates 51 are arranged at intervals. The two connecting plates 51 and the top wall of the shield tunnel 4 together enclose a clamping space 52. Specifically, the connecting plates 51 have a first supporting side and a second supporting side arranged vertically. The first supporting side of the connecting plates 51 is connected to the top wall of the shield tunnel 4. The fastening member 53 is threadedly connected to the first supporting side of one of the connecting plates 51. During the splicing process, the prefabricated middle partition wall 3 is inserted into the second groove 14 and the clamping space 52 at the same time, and the fastening member 53 is screwed inward to abut against the side wall of the prefabricated middle partition wall 3. One side of the prefabricated middle partition wall 3 abuts against the fastening member 53, and the other side of the prefabricated middle partition wall 3 abuts against the connected second supporting side.

[0050] It should be noted that there is a gap between the second end of the prefabricated middle partition wall 3 and the top wall of the shield tunnel 4, and the second groove 14 and the clamp 5 abut and limit the prefabricated middle partition wall 3 to the left and right, and the prefabricated middle partition wall 3 is not subjected to force in the length direction and height direction of the prefabricated bottom bin 1. Under the action of an earthquake, the seismic deformation of the shield tunnel 4 is transmitted to the prefabricated middle partition wall 3 through the abutment, and the prefabricated middle partition wall 3 generates a bending deformation. Since there is a gap between the prefabricated middle partition wall 3 and the top wall of the clamping space 52, a certain relative movement can be generated between the prefabricated middle partition wall 3 and the shield tunnel 4, which releases the bending internal force of the prefabricated middle partition wall 3 to a certain extent.

[0051] Furthermore, both ends of the prefabricated middle partition wall 3 are wrapped with flexible materials, the first end of the prefabricated middle partition wall 3 is in contact with the first connection surface 11 through the flexible material, and the second end of the prefabricated middle partition wall 3 is in contact with the abutting member 53 through the flexible material. Exemplarily, the flexible material can be rubber. The hard contact of the prefabricated middle partition wall 3 is upgraded to flexible contact. Under the action of an earthquake, the flexible material undergoes elastic deformation before the prefabricated middle partition wall 3 to absorb part of the earthquake deformation, so as to reduce the earthquake response of the prefabricated middle partition wall 3.

[0052] In order to further reduce the seismic response of the prefabricated intermediate partition wall 3, a viscoelastic or viscous damping material may be provided on the abutting surface of the abutting member 53 to provide a damping reaction force and consume vibration capacity under the action of an earthquake.

[0053] Furthermore, the first connecting surface 11 is an arcuate surface, the second connecting surface 12 is a plane, and an avoidance cut surface 15 is provided between the first connecting surface 11 and the second connecting surface 12. In the embodiment of the present application, the width of the second connecting surface 12 is the maximum width of the prefabricated bottom bin 1, and the setting of the avoidance cut surface 15 reduces the width of the prefabricated bottom bin 1 to a certain extent, so as to facilitate the movement of the prefabricated bottom bin 1 into the shield tunnel 4.

[0054] Furthermore, the prefabricated bottom bin 1 and the prefabricated middle partition wall 3 are provided with grabbing hand holes to facilitate the hoisting of the prefabricated bottom bin 1 and the prefabricated middle partition wall 3 .

[0055] Example 2

[0056] In another specific embodiment of the present application, a method for assembling an assembly component is provided. The assembly component is the assembly component in the above embodiment. The assembly component is assembled into the shield tunnel 4 by the assembly method. Figure 7 As shown, the assembly method includes:

[0057] Step S1: placing the bag 2 on the first connecting surface 11 of the prefabricated bottom bin 1 .

[0058] Specifically, a first groove 13 is provided on the first connecting surface 11 , and the pouch 2 is bonded to the groove bottom and at least a portion of the groove sidewall of the first groove 13 .

[0059] Step S2: Move the prefabricated bottom bin 1 into the shield tunnel 4 and adjust the position of the prefabricated bottom bin 1 so that there is a preset gap between the first connecting surface 11 and the inner wall of the shield tunnel 4 .

[0060] Specifically, the mechanical equipment can lift the bottom of the prefabricated bottom bin 1 or lift it through the hollow part of the prefabricated bottom bin 1 by the mechanical arm, or lift it by grabbing the grabbing hand hole on the prefabricated bottom bin 1, and move the prefabricated bottom bin 1 to the preset position of the tunnel. By lifting or by auxiliary parts, a preset gap is maintained between the first connecting surface 11 and the inner wall of the shield tunnel 4.

[0061] Wherein, in the process of moving the prefabricated bottom bin 1, the prefabricated bottom bin 1 can be assisted in positioning by an electronic monitoring device. Exemplarily, the electronic monitoring device includes a first displacement sensor and a controller, and the first displacement sensor is installed on the second connecting surface 12 of the prefabricated bottom bin 1, and the first displacement sensor is connected to the controller signal. The first displacement sensor is used to collect the distance between the second connecting surface 12 and the highest point of the prefabricated bottom bin 1, and transmit the distance information to the controller; the controller includes a comparison module and an output module, and the comparison module is set with calibrated distance information. The comparison module compares the received distance information with the calibrated distance information to obtain a comparison result, and the comparison result is output by the output module; when the distance information is consistent with the calibrated distance information, the position adjustment of the prefabricated bottom bin 1 is stopped; when the distance information is inconsistent with the calibrated distance information, the position of the prefabricated bottom bin 1 continues to be adjusted until it is consistent with the calibrated distance information.

[0062] Step S3: injecting a flexible grouting material 21 into the bag 2 so that the bag 2 abuts against the inner wall of the shield tunnel 4 .

[0063] Specifically, the grouting equipment injects flexible grouting material 21 into the bag 2. During the injection process, the grouting equipment can monitor the grouting pressure in real time so that most or all of the weight of the prefabricated bottom bin 1 is borne by the bag 2 after grouting; and the grouting equipment has the ability to independently adjust the grouting amount of the bag 2 at different positions, and further adjust and control the posture of the prefabricated bottom bin 1 by adjusting the grouting amount at different positions to meet the assembly accuracy requirements.

[0064] Among them, during the grouting process, the bag 2 can automatically adapt to the splicing misalignment between the shield segments 41, that is, there is a position difference between the shield segments 41. During grouting, the flexible grouting material 21 is a fluid, and the liquid flexible grouting material 21 can adapt to the splicing misalignment and make up for the position difference so that the bag 2 and the segment are seamlessly connected; after the flexible grouting material 21 hardens, the grouting bag 2 can evenly transfer the load between the prefabricated bottom bin 1 and the shield tunnel 4 after grouting.

[0065] Step S4: Connect the prefabricated middle partition wall 3 between the second connecting surface 12 of the prefabricated bottom bin 1 and the top of the shield tunnel 4 .

[0066] Specifically, a second groove 14 is provided on the second connection surface 12, and the second groove 14 is extended along the length direction of the prefabricated bottom bin 1. A clamp 5 is provided on the top of the shield tunnel 4, and the clamp 5 has a clamping space 52 and a fastening member 53. The clamping space 52 is extended along the length direction of the prefabricated bottom bin 1, wherein the distance between the bottom of the second groove 14 and the top wall of the clamping space 52 is greater than the height of the prefabricated middle partition wall 3. The mechanical equipment moves the prefabricated middle partition wall 3 into the shield tunnel 4, and pushes it into the second groove 14 and the clamping space 52, so that the first end of the prefabricated middle partition wall 3 abuts against the bottom of the second groove 14, and there is a gap between the second end of the prefabricated middle partition wall 3 and the top wall of the clamping space 52, and the position of the fastening member 53 is adjusted so that the fastening member 53 abuts against the side wall of the prefabricated middle partition wall.

[0067] In the process of moving the prefabricated middle partition wall 3, the electronic monitoring device can be used to assist in positioning the prefabricated middle partition wall 3. Exemplarily, the electronic monitoring device includes a second displacement sensor and a controller, the second displacement sensor is installed at the center of the push-in surface of the prefabricated middle partition wall 3, and the second displacement sensor is connected to the controller signal. The second displacement sensor is used to collect first distance information between the center position of the push-in surface and the side wall of the second groove 14, and to collect second distance information between the center position of the push-in surface and the bottom of the second groove 14, and transmit the first distance information and the second distance information to the controller; the controller includes a comparison module and an output module, and the comparison module is set with first calibrated distance information and second calibrated distance information. The comparison module compares the received first distance information with the first calibrated distance information, and compares the received second distance information with the second calibrated distance information to obtain a first comparison result and a second comparison result, which are output by the output module; when the first distance information is consistent with the first calibrated distance information and the second distance information is consistent with the second calibrated distance information, the position adjustment of the prefabricated middle partition wall 3 is stopped; when the first distance information is inconsistent with the first calibrated distance information or the second distance information is inconsistent with the second calibrated distance information, the position of the prefabricated middle partition wall 3 continues to be adjusted.

[0068] Further, in step S2, the prefabricated bottom bin 1 is moved into the shield tunnel 4, and the position of the prefabricated bottom bin 1 is adjusted so that there is a preset gap between the first connecting surface 11 and the inner wall of the shield tunnel 4, including:

[0069] Step S21: Connect the leveling bolts 6 to the bottom of the prefabricated bottom bin 1.

[0070] Specifically, a through threaded hole is provided at the bottom of the prefabricated bottom bin 1, and the leveling bolt 6 is connected to the threaded hole, and the leveling bolt 6 is arranged perpendicular to the first connecting surface 11. In order to more stably support the prefabricated bottom bin 1, at least four leveling bolts 6 are provided.

[0071] Step S22 : adjusting the length of the leveling bolt 6 so that the leveling bolt 6 abuts against the inner wall of the shield tunnel 4 .

[0072] Specifically, a gasket is provided on the inner wall of the shield tunnel 4, and the leveling bolt 6 abuts against the inner wall of the shield tunnel 4 through the gasket, so as to concentrate the stress generated by the contact at the joint point.

[0073] Furthermore, the assembling method further comprises: after the flexible grouting material 21 in the bag 2 is hardened, removing the leveling bolt 6 .

[0074] Specifically, the leveling bolts 6 are rigidly abutted against the inner wall of the shield tunnel 4 to prevent earthquake deformation from being transmitted to the shield bottom bin through the leveling bolts 6. After the flexible grouting material 21 in the bag 2 hardens, the leveling bolts 6 can be removed.

[0075] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0076] 1. There is a preset gap between the first connecting surface 11 of the prefabricated bottom bin 1 and the inner wall of the shield tunnel 4. The first connecting surface 11 is in contact with the inner wall of the shield tunnel 4 through the grouting bag 2. The elastic modulus of the flexible grouting material 21 in the bag 2 after hardening is less than or equal to the elastic modulus of the prefabricated bottom bin 1. Under the action of an earthquake, the flexible grouting material 21 in the bag 2 is deformed before the prefabricated bottom bin 1 to absorb part of the earthquake deformation, thereby reducing the earthquake deformation transmitted to the prefabricated bottom bin 1, so that the assembly components have the ability to absorb earthquake deformation.

[0077] 2. The inner wall of the shield tunnel 4 is formed by splicing a plurality of shield segments 41. There is a splicing misalignment between adjacent shield segments 41, that is, there is a position difference between the shield segments 41. During grouting, the flexible grouting material 21 is a fluid, and the liquid flexible grouting material 21 can adapt to the splicing misalignment and compensate for the position difference so that the bag 2 and the segment are seamlessly connected.

[0078] 3. There is a gap between the second end of the prefabricated middle partition wall 3 and the top wall of the shield tunnel 4. The second groove 14 and the clamp 5 abut and limit the prefabricated middle partition wall 3 to the left and right. The prefabricated middle partition wall 3 is not subjected to force in the length direction and height direction of the prefabricated bottom bin 1. Under the action of an earthquake, the seismic deformation of the shield tunnel 4 is transmitted to the prefabricated middle partition wall 3 through the abutment member, and the prefabricated middle partition wall 3 generates a bending deformation. Since there is a gap between the prefabricated middle partition wall 3 and the top wall of the clamping space 52, a certain relative movement can be generated between the prefabricated middle partition wall 3 and the shield tunnel 4, which releases the bending internal force of the prefabricated middle partition wall 3 to a certain extent.

[0079] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0080] In addition to the above, it should be noted that "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the embodiment included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a specific feature, structure or characteristic in conjunction with any embodiment, it is claimed that the realization of such feature, structure or characteristic in conjunction with other embodiments also falls within the scope of the present invention.

[0081] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
