Description

Technical Field

[0001] The utility model relates to the technical field of shield segments, in particular to an assembly structure of shield segments. Background Art

[0002] As the permanent lining structure of the shield tunnel, the shield segment is the innermost barrier of the tunnel, responsible for resisting soil pressure, groundwater pressure and some special loads. Traditional shield segment assembly mostly uses longitudinal and circumferential arc bolts. Arc bolts are easy to deform, and it is often difficult to pierce the arc bolts during construction. At the same time, special personnel are required to lock and re-tighten the bolts, which consumes a lot of time and manpower, making the assembly process more troublesome.

[0003] For example, China's utility model CN215761699U quickly assembles the connection structure of the shield segments, the shield segments and the permanent lining structure, and designs a shield segment that can be quickly assembled. The principle is that male joints and wooden sockets are provided at both ends of the shield segment, and plug blocks and slots are provided on both sides of the shield segment. When connecting, the plug blocks and slots are used to assemble the shield segments into a circular tube shape, and then the design of male joints and female sockets can be used to splice multiple circular tubes together.

[0004] However, in the existing device, once the male connector and the female socket are connected, they cannot be removed. During the design work, the adapted shield segment needs to be installed in the appropriate position, which has a low error tolerance rate. Once the installation is wrong, it cannot be removed and can only be destroyed and removed, which is too cumbersome. Therefore, in response to the above problems, a removable shield segment device is designed to improve the error tolerance rate and make the segments interlock and not easy to separate.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0029] As the permanent lining structure of the shield tunnel, the shield segment is the innermost barrier of the tunnel, responsible for resisting soil pressure, groundwater pressure and some special loads. Traditional shield segment assembly mostly uses longitudinal and circumferential arc bolts. Arc bolts are easy to deform, and it is often difficult to pierce the arc bolts during construction. At the same time, special personnel are required to lock and re-tighten the bolts, which consumes a lot of time and manpower, making the assembly process more troublesome.

[0030] In the related art, male joints and wooden sockets are provided at both ends of the shield segment, and plugs and slots are provided on both sides of the shield segment. When connected, the shield segment is assembled into a round tube shape using the plugs and slots, and multiple round tubes can be spliced ​​together using the design of male joints and female sockets. However, when the existing device is in use, the male joint and the female socket cannot be removed once connected. During the design work, the adapted shield segment needs to be installed in a suitable position, and the fault tolerance rate is low. Once the installation is wrong, it cannot be removed and can only be destroyed, which is too cumbersome.

[0031] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides an assembly structure of the shield segment. When the segment 11 needs to be assembled, the insertion rod 13 is inserted into the interior of the slot body 12. When inserting it again, the block 22 is squeezed and retracted to cooperate with the inside of the insertion rod 13 and push the connecting rod 23 to rotate, so that one end of the connecting rod 23 pushes the slide plate 24 to move to one side and squeezes the spring 25, so that when the block 22 is offset from the card plate 21, the spring 25 rebounds and pushes the slide plate 24 to move. The block 22 is pushed upward by the connecting rod 23 to cooperate with the card plate 21 to assemble the two segments 11. When assembling, pay attention to inserting the two insertion rods 13 into the interior of the slot body 12 on the two segments 11, so that the segments 11 are assembled in an interlaced manner, which can make the connection stability after the assembly is completed higher.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figure 1-Figure 4 The embodiment of the present application provides an assembly structure of a shield segment, including: a segment 11 having a groove 12 at one end; a rod 13 arranged at the other end of the segment 11; a connecting component 2 is arranged inside the groove 12 and the rod 13, and the connecting component 2 includes: a clamping plate 21 fixedly arranged inside the groove 12; a clamping block 22 with its bottom inserted into the rod 13; a connecting rod 23 symmetrically hinged at the bottom of the clamping block 22; a slide plate 24 slidably arranged inside the rod 13 and hinged at the other end of the connecting rod 23; a spring 25 is arranged inside the rod 13, and both ends are connected to the inner side wall of the rod 13 and the slide plate 24.

[0034] Specifically, the two ends of the spring 25 are fixedly connected to the slide plate 24 and the inner wall of the insertion rod 13 by means of a snap ring. The fixing method of the snap ring belongs to the existing well-known technology and will not be described in detail here.

[0035] When in use, first insert the rod 13 into the slot 12, and then insert the block 22 to be squeezed and retracted to match the inside of the rod 13 and push the connecting rod 23 to rotate, so that one end of the connecting rod 23 pushes the slide 24 to move to one side and squeezes the spring 25, so that when the block 22 and the card plate 21 are offset, the spring 25 rebounds and pushes the slide 24 to move, and the connecting rod 23 pushes the block 22 to move upward to match the card plate 21 to assemble the two segments 11. When assembling, pay attention to inserting the two rods 13 into the slots 12 on the two segments 11, so that the segments 11 are staggered and assembled, which can make the connection stability after assembly higher. If the installation position is wrong, the segment 11 can be disassembled by pressing the block 22 to make the block 22 retract and match the inside of the rod 13.

[0036] In some embodiments, the outer side wall of the slide plate 24 fits with the inner side wall of the insertion rod 13 .

[0039] During use, the rod body 26 can be arranged so that when the spring 25 is compressed, the rod body 26 can limit it and prevent it from bending during compression, thereby better protecting the spring 25.

[0040] In some embodiments, the connecting assembly 2 further includes: a baffle 27 disposed at one end of the rod body 26 .

[0041] When in use, the baffle 1 27 can prevent the slide plate 24 and the rod body 26 from separating.

[0042] In some embodiments, the connecting assembly 2 further includes: a second baffle 28 disposed at the bottom of the clamping block 22 .

[0043] When in use, the baffle plate 28 can prevent the block 22 from being separated from the insertion rod 13.

[0044] In some embodiments, the connecting rod 23 is symmetrically disposed at the bottom of the block 22 .

[0045] When in use, the two connecting rods 23 can push the block more stably.

[0046] In some embodiments, the connection assembly 2 further includes: a ring body 29 disposed on an outer side wall of one end of the tube segment 11 .
