Description

Technical Field

[0001] The invention relates to the technical field of tunnel reinforcement, and in particular to a shield tunnel convergence deformation reinforcement device. Background Art

[0002] During the operation of the shield tunnel, due to the influence of various factors such as the ground, the load of surrounding buildings and soil disturbance, the construction of tunnel surrounding projects, the construction of tunnel engineering structures and the vibration of subway trains, the tunnel inevitably produces convergence deformation, and slowly changes from a round shape to a "duck egg shape" (vertical compression, horizontal expansion). As the operation time of the tunnel increases, this deformation gradually accumulates. On the one hand, it will pose a huge threat to the structural safety of the tunnel itself. On the other hand, excessive convergence deformation of the tunnel will invade the tunnel construction limit and even the equipment limit, seriously threatening the operation safety. The existing technology uses reinforcement brackets for reinforcement, but the position of the tunnel docking is prone to misalignment at different positions. The existing brackets cannot be reinforced for the misaligned position of the track, causing the misaligned position to become more and more serious.

DETAILED DESCRIPTION

[0017] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 8It can be clearly presented in the detailed description of the embodiments that the structural contents mentioned in the following embodiments are all referenced to the drawings in the specification.

[0018] This embodiment provides a shield tunnel convergence deformation reinforcement device, as shown in the attached Figure 1-8 As shown in the instruction manual, Figure 1 This is the main view of this scheme. The main view has three cutting planes, namely AA, BB, and CC. The three cutting planes are respectively provided with corresponding cutting diagrams attached to the manual. Figure 5 , 6 and 7, Instruction Manual Figure 2 The fixing position of the reinforcement ring 1 is shown. The fixing position of the reinforcement ring 1 is set at the interface of the two tunnels 20. Figure 3 is a three-dimensional schematic diagram of the reinforcement ring 1, and the instruction manual is attached. Figure 7 The top of the support rod 6 is cut to facilitate observation of the internal shape of the support rod 6. Figure 8 The details of the rotating ring 5 are mainly shown. The reinforcement ring 1 is provided with a No. 1 bag 2 and a No. 2 bag 3. There is no substantial difference between the No. 1 bag 2 and the No. 2 bag 3. The structures of the two are the same and they are distinguished only by the names. The two air bags are connected through an internal channel 4. When the tunnel 20 is not offset, the shapes of the No. 1 bag 2 and the No. 2 bag 3 are roughly the same (because they are all attached to the tunnel 20). However, since the tunnel 20 is deformed, that is, it is offset at the original connection position, one of the air bags will inevitably be squeezed during the offset process, and the gas will be squeezed into the other air bag, which will expand. A slidable support rod 6 is provided inside the No. 1 bag 2 or the No. 2 bag 3. The support rod 6 is attached to the instruction manual. Figure 1-8The number of support rods 6 is three, and the number of support rods 6 is actually several, and the reinforcement ring 1 is annularly arranged, so that the offset position will have a corresponding or nearby support rod 6, so that the offset position will squeeze the support rod 6 so that the support rod 6 moves toward the center of the reinforcement ring 1, and the support rod 6 is slidably arranged on the support tube 7, and the support tube 7 and the support rod 6 are sealed and slidable, and a compression space is formed between the support tube 7 and the support rod 6, and there is gas inside this space, and the gas cannot be discharged (although an extension rod is provided on one side of the support rod 6 8, but the extension rod 8 is also sealed with the support tube 7, and the support rod 6 and the No. 1 bag 2 or the No. 2 bag 3 are also sealed and slidable), and this space is compressed at the beginning of this scheme, that is, the support rod 6 will automatically move toward the circular outer side of the reinforcement ring 1 without external force, that is, this compression interval acts as a spring so that the support rod 6 can move toward the outside so that the support rod 6 contacts the surface of the tunnel 20 to form a support, and when the tunnel 20 deviates, it will become more and more difficult to squeeze the support rod 6, because the gas in the space cannot be removed, which can deal with the deviation. The tunnel 20 is shifted away from the support rod 6, and the support rod 6 will control the space gas to contact the tunnel 20. The present solution has a pouring hole 26. When the deformation reaches a certain degree, the pouring hole 26 will automatically open. At this time, the operator can pour concrete to make the concrete fixed (the effect brought by the deformation of the No. 1 capsule 2 and the No. 2 capsule 3). In addition, several support rods 6 contact and support the tunnel 20, which can act as a supporting component and a reinforcing rib between the concrete. It can perfectly adapt to the reinforcement of the concrete and can also support and reinforce it at the offset position. The present solution is provided with The rotating ring 5 can be driven by one of the largest extruded support rods 6. Here, a maximum is introduced. Because the offset position is variable, it can be offset at any position, which leads to inconsistent extrusion lengths of several support rods 6. In order to enable multiple groups of support rods 6 to identify whether the offset position of the tunnel 20 has reached the situation where pouring is required, an oblique groove 9 is set. The oblique groove 9 is opened on the upper and lower sides of the rotating ring 5. The oblique groove 9 is an oblique groove, but this groove has an entry end, and the position of this entry end just corresponds to the other end of the extension rod 8, as shown in the attached manual. Figure 8As shown, since a buffer groove 11 is correspondingly arranged on one side of the oblique groove 9, the buffer groove 11 is an annular groove, and this groove generally provides the support rod 6 with a buffer space (that is, it generally does not enter the oblique groove 9), and it will not enter the oblique groove 9 until it is squeezed to a certain position, which also means that it will not enter the oblique groove 9 until it is squeezed to a certain depth. When entering the oblique groove 9, the support rod 6 is restricted to slide horizontally, resulting in that when the support rod 6 enters the oblique groove 9, the rotating ring 5 (the rotating ring 5 is rotatably arranged on the reinforcement ring 1, and in order to ensure that the rotating ring 5 can rotate normally, a corresponding frame is arranged on the inner side of the reinforcement ring 1 so that the rotating ring 5 can rotate stably, and lubricating oil can be arranged between the two to ensure that the rotating ring 5 can rotate), but when the rotating ring 5 rotates, the extension rods 8 of other groups will not be able to enter the oblique groove 9, so that the support rod 6 with the maximum squeezing will drive the rotating ring 5 to rotate, and Once the rotating ring 5 is rotated, the entrance on one side of the oblique groove 9 will be offset, resulting in the inability of other groups of support rods 6 to enter the oblique groove 9, that is, the support rod 6 with the maximum extrusion distance drives the rotating ring 5 to rotate, without limiting which support rod 6 drives the rotating ring 5 to rotate. Several support rods 6 can drive the rotating ring 5 to rotate, so that the rotating ring 5 can be driven by one of the support rods 6 with the maximum extrusion movement distance. In this way, the degree of offset can be judged, and the rotation of the rotating ring 5 of the present scheme can drive multiple groups of mechanisms to operate, and the rotation of the rotating ring 5 can drive multiple groups of positioning rods 13 to move, because the positioning rod 13 is slidably set on the small cylinder, and the small cylinder is also fixedly set on the reinforcement ring 1, and the interior of the small cylinder is also sealed and slidably provided with a positioning rod 13, and there is also a compression space between the positioning rod 13 and the small cylinder, and the gas in this space is also compressed, which is the same as the principle of the support rod 6 and the support cylinder 7, as shown in the attached manual. Figure 5 As described above, driven by the compression space, the positioning rod 13 will move downward (numbered) and will be inserted into the positioning groove 12. In the figure, the small tube is suspended, but in fact it is not. Instead, it is fixed on the reinforcement ring 1, so that the positioning rod 13 can be inserted into the positioning groove 12 for fixing, which actually acts as a spring. The top of the positioning rod 13 is overlapped on the release ring 10. The release ring 10 is a ring with an L-shaped cross section, which can just overlap the positioning rod 13. As shown in the attached manual Figure 8 As shown, one side of the release ring 10 has a notch, and when the notch is rotated, the positioning rod 13 cannot be overlapped. The positioning rod 13 is inserted into the positioning groove 12 under the drive of the compression space to fix the support rod 6, so that the support rod 6 can fix the tunnel 20. After that, concrete pouring is required. For the first time, the support rod 6 is inserted into the positioning groove 12, and it can be reinserted by moving a short distance.

[0019] The rotation of the rotating ring 5 can also drive the closing valve 14 to rotate. The closing valve 14 is as shown in the attached manual. Figure 5 As shown, at this time, the pouring hole 26 cannot flow, and when it reaches a certain position, the closing valve 14 will be opened, because the rotation of the rotating ring 5 can make the vertical plate 15 move upward, and the vertical plate 15 is slidably arranged on one side of the reinforcement ring 1, and slides vertically upward, and the bottom of the vertical plate 15 is just above the release ring 10, and the top of the release ring 10 is arranged on the top block 16, and the top block 16 is an inclined surface, so the rotation of the rotating ring 5 can make the top block 16 drive the vertical plate 15 to move upward, and the upward movement of the vertical plate 15 can make the closing valve 14 rotate, because the top of the vertical plate 15 It has a transverse notch, the surface of the transverse notch overlaps one side of the closing valve 14, one side of the closing valve 14 is extended and obliquely overlapped above the vertical plate 15, so that the vertical plate 15 moves upward to rotate the closing valve 14, that is, to open the closing valve 14, and a pressure sensor is arranged inside the No. 1 capsule 2 to detect whether the closing valve 14 is opened. When the closing valve 14 opens, the pressure sensor notifies the maintenance personnel to cast the No. 1 capsule 2 and the No. 2 capsule 3. The rotation of the rotating ring 5 can also make the shut-off valve 27 block the internal channel 4, because the internal channel 4 is connected to the No. 1 capsule 2 and the No. 2 capsule 3. When casting is required At that time, the position ensures that the No. 1 bag 2 and the No. 2 bag 3 are filled completely, so the internal channel 4 is closed before pouring. Because a protrusion 29 is provided above the rotating ring 5, and the stop valve 27 is slidably provided on one side of the sealing channel, the stop valve 27 is moved toward the internal channel 4 under the action of the protrusion 29, and spring pieces 28 are provided on both sides of the stop valve 27. The spring piece 28 is tilted toward both sides and will be deformed and reset after being squeezed. Therefore, when the stop valve 27 is inserted into the internal channel 4, the spring piece 28 will be squeezed by the box, and the spring piece 28 will be reset after entering, so as to achieve the effect of preventing it from falling off. The shut-off valve 27 will block the internal channel 4 and cannot be detached. Finally, the role of the hydraulic rod 21 of this solution is introduced. The reinforcement ring 1 of this solution is fixed to the tunnel 20 through the holes on both sides of the bottom, and the hydraulic rod 21 is also fixed to the tunnel 20. Whether it is the tunnel 20 where the hydraulic rod 21 is installed or the adjacent tunnel 20, it does not affect the use of the reinforcement ring 1. The position of the hydraulic rod 21 is fixed, and it does not support the support rod 19 when it is not deformed. The support rod 19 is not a rod, but two rods. The two rods form a group of telescopic rods. This group of telescopic rods is the support rod 19 introduced in this solution, as shown in the attached manual Figure 1 , 2As shown in FIG. 3 , the support rod 19 has a telescopic distance, and the present solution requires the support rod 19 to be vertical. During the vertical process, the translation block 18 is translated and slid, so the support rod 19 will shrink. The present solution is limited to the support rod 19 cannot shrink when the support rod 19 is vertical, thus ensuring that the support rod 19 can support the reinforcement ring 1 when it is vertical. The translation block 18 of the present solution is driven by the arc piece 25, because the arc piece 25 is arranged at the inner arc of the rotating ring 5, as shown in the attached manual. Figure 7 and 8 As shown, at this time, the rotation of the rotating ring 5 can control the lateral movement of the translation block 18. The movement of the translation block 18 drives the support rod 19 to be horizontal, and at the same time, the fixed block 22 fixes the translation block 18. Because one side of the translation block 18 is set as an inclined surface, corresponding to the shape of the one-way block 23, the one-way block 23 can be squeezed by the translation block 18, and then clamped on one side of the translation block 18, and the other side enters the fixed block 22 to be fixed. The one-way spring 24 is responsible for resetting the one-way block 23, and the fixed block 22 is fixed by the hydraulic rod 21, so it is equivalent to the hydraulic rod 21 supporting the support rod 19, and the support rod 19 supports the reinforcement ring 1, so as to achieve the effect of supporting the reinforcement ring 1. At one end of the translation block 18, the support rod 19 is correspondingly provided with a socket and an insert block 30 (the socket is on the support rod 19 on one side of the number 30, as shown in the attached manual Figure 7As shown, the insertion spring 31 is squeezed at this time), the support rod 19 can be inserted when it is horizontal to complete the positioning, and the bottom of the support rod 19 can be welded to the tunnel 20 when it is vertical. Finally, one point should be noted that when the deviation groove is rotated to a specific position, the vertical support rod, the positioning rod insertion, the shut-off valve shut-off and the closing valve opening effects introduced in this scheme correspond to each other at the same time. For example, the arc piece drives the support rod to be vertical, and it is only necessary to set the angle and slope of the arc piece or the corresponding gear combination (the gear combination is set when the angle is not enough, and the gear combination is added to cooperate with the rotation of the arc piece, so that the support rod can reach a specific position. These are achieved with the help of the gear transmission ratio. Under normal circumstances, the angle and slope corresponding to the arc piece can also be set to realize the vertical support rod and achieve the corresponding oblique direction The invention relates to a reinforcing ring 1, wherein an offset extrusion mechanism is arranged on one side of the reinforcing ring 1, and the offset extrusion mechanism comprises a No. 1 capsule 2, a No. 2 capsule 3 and an internal channel 4, the No. 1 capsule 2 is integrally arranged on one side of the reinforcing ring 1, the No. 2 capsule 3 is integrally arranged on the other side of the reinforcing ring 1, an internal channel 4 is arranged between the No. 1 capsule 2 and the No. 2 capsule 3, the internal channel 4 is arranged inside the reinforcing ring 1, a rotating ring 5 is rotatably arranged on the inner side of the reinforcing ring 1, a casting support mechanism is arranged on one side of the reinforcing ring 1, and the casting support mechanism comprises a support rod 6 and a support tube 7, the support rod 6 is slidably arranged on one side of the reinforcing ring 1, the support tube 7 is integrally arranged on the inner side of the reinforcing ring 1, one side of the support rod 6 is sealed and slidably provided with the support tube 7, one side of the support rod 6 is integrally provided with an extension rod 8, and a rotating ring 5 is rotatably arranged on the inner side of the reinforcing ring 1, and a casting support mechanism comprises a support rod 6 and a support tube 7.
