[0002] The assembly of shield segments is a key construction step in tunnel construction, which is related to the safety of tunnel construction, construction period, etc. At present, the commonly used segment assembly process in China is to use bolts for connection. Its characteristics are that the shield stops excavation first, and then the segment assembly machine transports the segments to the designated location, and then the segments are manually bolted to make the segment joints tight and reliable. Due to the complex assembly process of bolt connection, the assembly takes a long time and requires downtime, and the bolts need to be tightened and fixed at a certain time during the connection process, which causes a significant increase in working time and affects the efficiency of shield excavation.

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 8 It 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 segment connection structure, as shown in the attached Figure 1-8 As shown in the instruction manual, Figure 1 This is a three-dimensional structural diagram of this scheme, and the instruction manual is attached. Figure 2 Cut along the top of the rotating ring 2 to show the shape of the rotating ring 2. Figure 4 This is a schematic diagram of the docking of the two sides of the rotating ring 2. Figure 5 The upper structure of the rotating ring 2 is cut off to facilitate observation of the upper structure of the rotating ring 2. The instruction manual is attached. Figure 6 The pipe segment 1 is hidden, and the instruction manual is attached. Figure 7 The extrusion valve 19 and one side of the docking rod 9 are cut. The manual intentionally cuts one side of the pipe segment 1. The design core of this scheme is the rotating ring 2. The rotating ring 2 is a piece with an annular angle, which is sixty degrees in the scheme. The pipe segment 1 is also sixty degrees, so six pipe segments 1 are needed to form an annular circle, which also requires the left side of the rotating ring 2 to dock with the right side of the rotating ring 2 to form an annular docking. This is the horizontal docking of this scheme. This scheme also has a vertical docking. The vertical docking of this scheme is the docking rod 9 and the pressing rod 10. The left side of the rotating ring 2 is a docking structure, and the right side of the rotating ring 2 is a fastening structure. The rotating ring 2 of this scheme can rotate. The rotation of the rotating ring 2 depends on the pressing rod 10. A bevel block 11 is provided on one side of the pressing rod 10. During the downward movement of this bevel block 11, the rotating block 12 can rotate and move, as shown in the attached manual. Figure 6 As shown, the rotating block 12 is rotatably arranged on the rotating ring 2, and an anti-slip structure is arranged between the two, so that the rotating block 12 can rotate above the rotating ring 2, and when the pressing rod 10 moves downward, the rotating block 12 can drive the rotating ring 2 to rotate clockwise. Because a corresponding chamfer 14 is arranged on one side of the rotating block 12, corresponding to the shape of the inclined block 11, the inclined block 11 moves downward to push the rotating ring 2 and the rotating block 12 to rotate together, and after the pipe segment 1 of this scheme is annularly butted, the rotating ring 2 rotates, so that the rotating ring 2 rotates inside the annular tunnel, achieving The effect of rotational dislocation is achieved, so that one side of a rotating ring 2 on a single pipe segment 1 is inserted into the pipe segment 1 next to it, and when the rotating ring 2 rotates, the rotating ring 2 can form a complete ring, so that the complete ring connects the scattered pipe segments 1, so that the whole group of pipe segments 1 is stable. On the premise that the rotating ring 2 rotates, the two side structures of the rotating ring 2 are set, and a rectangular interface is set on both sides of the rotating ring 2. The structures on both sides of the rectangular interface are connected to each other. In order to facilitate the understanding of this solution, a single pipe segment 1 is connected to the next pipe segment 1 on the other side, as shown in the attached manual Figure 2As shown, there is a dotted line on the left side, which cuts the whole, and the structure on the curved side appears on the side of the label A, so that a docking is formed for easy understanding. Figure 5 and 6 The same meaning is also provided in the instruction manual. Figure 3 As shown, at this time, the clockwise rotation of the rotating ring 2 will cause the torsion block 6 to rotate. There is a long rod above the torsion block 6, which is overlapped on the guide groove 15, and the guide groove 15 is provided on the pipe segment 1. Therefore, the rotation of the rotating ring 2 can cause the torsion block 6 to rotate counterclockwise. During the rotation of the torsion block 6, it can also overlap on the positioning block 5, because a slidable slider 7 is provided on one side of the torsion block 6, and a round rod is provided on one side of the slider 7. One side of the round rod is an inclined surface, which can extend to the left side of the positioning block 5, thus forming a complete inclined surface with the positioning block 5. When the torsion block 6 rotates, the round rod can slide along the complete inclined surface. Since there is a sliding distance between the torsion block 6 and the slider 7, the slider 7 can enter the attached manual. Figure 3At the position of the label 5, a snap connection is formed. Here, a structure that does not appear in this scheme needs to be introduced, that is, a structure that forms a complete inclined surface with the positioning block 5. This structure is on one side of the round block of the slider 7, just overlapping the inclined surface, and this inclined surface is integrally arranged on one side of the rotating ring 2 and on both sides of the slider 7, so that the slider 7 can overlap the positioning block 5. Due to the setting of the sliding distance between the torsion block 6 and the slider 7, the slider 7 reaches the maximum distance when it reaches the middle of one side of the positioning block 5, so that the slider 7 overlaps the positioning block 5, and The structure of the slider 7 and the torsion block 6 is on the other side of the rotating ring 2, so that one side of the rotating ring 2 is overlapped on the next rotating ring 2 to form a complete closed loop, and an insertion block 8 is slidably arranged on one side of the torsion block 6, and corresponding circular holes are arranged on the upper and lower sides of the insertion block 8. A corresponding rod is arranged on one side of the number 8, and this rod ensures that the insertion block 8 slides toward the insertion groove 3, and one side of the insertion block 8 extends to the bottom of the torsion block 6. When the torsion block 6 rotates, it can be inserted into the insertion groove 3 against the insertion block 8, and one side of the insertion block 8 is a The insertion groove 3 just corresponds to the end of the square. The insertion of the two will form a seal. In order to make the insertion block 8 easy to insert, the present invention provides an exhaust port 4 on one side. Since the ultimate goal of the present invention is to block the exhaust port 4, a seal is formed between the square end of the insertion block 8 and the inside of the insertion groove 3. In this way, a vacuum is formed on one side, which makes it difficult to pull out. The blocking of the exhaust port 4 depends on glue. The glue will be introduced in the next paragraph. The glue will reach one side of the rotating ring 2. When the insertion block 8 is inserted, due to the insertion block 8 The middle shape is an ellipse that can be squeezed and expanded, so the insertion process can become an ellipse with a large short axis, corresponding to the rotation of the insertion slot 3. Because the present scheme is configured and poured with glue, the glue will fill the ellipse after entering, and form an anti-slip structure with the ellipse, which is difficult to pull out, making it difficult to pull out one side of the rotating ring 2 to the next rotating ring 2. Under the bidirectional fixed setting, the rotating ring 2 is assembled and rotated to form a complete ring, and an anti-slip groove 24 is also provided on one side of the rotating ring 2. The shape of the anti-slip groove 24 is wider at the edge and narrower in the middle, as shown in the attached manual. Figure 6 As shown, an anti-slip block 17 is slidably arranged inside the pipe segment 1. The anti-slip block 17 is limitedly slidably arranged inside the pipe segment 1, and is not suspended as shown in the accompanying drawings. A spring is arranged above the anti-slip block 17, and the spring is in an extruded state in the figure. Therefore, once the rotating ring 2 rotates, the anti-slip groove 24 corresponds to the anti-slip block 17. In this way, under the action of the spring, the anti-slip block 17 is inserted into the rebound groove, so that the pipe segment 1 can fix the interface of the rotating rings 2 on both sides to form an overall fixing effect. It is only necessary to open a reserved sliding space on the pipe segment 1 to facilitate the anti-slip block 17 to slide downward;

[0019] This section introduces the structure that can be driven by the rotation of the control rotating ring 2. First, the rotating block 12 can be rotated and reset. Since the rotating block 12 can drive the rotating block 12 to rotate during the downward pressing of the pressing rod 10, in order to enable the rotating ring 2 of this scheme to fix the position of the pressing rod 10, a notch is provided on the edge of the pressing rod 10 to facilitate the rotation of the rotating ring 2. After the rotating ring 2 is rotated to a certain angle, the left side of the notch will reach the left side of the pressing rod 10, as shown in the attached manual. Figure 6 As shown, at this time, only the right side of the pressing rod 10 needs to be fixed to realize the fixing of the pressing rod 10. In order to fix the right side of the pressing rod 10, the present scheme sets a resettable rotating block 12, and a squeezing rod 16 is rotatably set on one side of the rotating block 12. The squeezing rod 16 is a telescopic rod, so there is a No. 1 rod and a No. 2 rod. The No. 1 rod is rotatably set on one side of the rotating block 12, and one end of the No. 2 rod is sealed and slid with the No. 1 pipe, and the other end of the No. 2 rod is rotatably set on the pipe segment 1. Since the interior between the two is in a hollow state, there is a storage The storage space cannot discharge gas, so when the No. 1 rod and the No. 2 rod are squeezed, the air inside will be compressed. In the process of the pressing rod 10 and the inclined block 11 moving downward, the inclined block 11 will eventually reach the bottom of the rotating block 12, so that the rotating block 12 has a reset space, and the rotating block 12 is reset under the driving force of the internal pressure of the squeezing rod 16 (a spring connecting the No. 1 rod and the No. 2 rod end to end can also be set inside the squeezing rod 16, so that the spring team squeezing rod 16 can be reset), that is, it returns to the state attached to the instruction manual. Figure 5 In this way, the pressing rod 10 is clamped between the rotating block 12 and the notch of the rotating ring 2, achieving the effect of fixing the pressing rod 10 to the left and right, and the pressing rod 10 cannot be reset upward at this time. A one-way groove is provided on the side of the pipe segment 1, and the annular angle formed by the one-way groove is smaller than the rotation angle of the rotating ring 2, and a guide strip 27 is provided on one side of the pipe segment 1, and the angle of the guide strip 27 is between the rotation angle of the one-way groove and the rotating ring 2. Due to the action of the guide strip 27, the one-way block 13 is squeezed during the rotation of the rotating block 12. A spring is provided on one side of the one-way block 13, and the spring is compressed. Therefore, once the rotating block 12 rotates to a certain position, the one-way block 13 will be released, as shown in the attached manual Figure 5 As shown, the guide bar 27 is an annular bar, most of which is blocked by the rotating block 12. Figure 5The annular shape extends all the way to the tail of the one-way groove, so that the last angle of the rotating block 12 will reach the edge of the one-way groove, that is, the right side in the figure, and after reaching the right side, it will be separated from the top movement of the guide strip 27. At this time, the one-way strip will reach the right side of the one-way groove under the reset of the spring and contact the inner wall of the pipe segment 1. After the extrusion rod 16 is reset, it pushes the rotating block 12 to reset. At this time, the one-way block 13 and the one-way groove form a one-way movement. As the rotating block 12 is reset, the one-way block 13 moves in the one-way groove. The pressing rod 10 can only be moved along the direction of the pressing rod 10 when it is connected, and cannot be rotated in the direction, so as to achieve the effect of fixing the pressing rod 10. The pressing rod 10 is pressed downward (multiple segments 1 are required to form a ring and then press multiple groups of pressing rods 10 together) to be connected to the docking rod 9. The docking rod 9 is provided with docking blocks 22 on both sides. Since the docking blocks 22 are arranged up and down, and the docking rod 9 of this scheme is fixedly arranged inside the segment 1, and the docking rod 9 needs to dock the pressing rod 10 up and down, it is attached to the manual. Figure 6 The dotted line also represents how the lower part of the docking rod 9 is connected to the pressing rod 10, so that the pressing rod 10 is automatically inserted into the docking rod 9 by pressing downward, and the docking rod 9 is successfully docked on the docking rod 9 from the bottom by pressing downward, forming a buckle fixation. In order to prevent the rotating ring 2 from resetting, the present invention is provided with a lifting column 26, and the lifting column 26 is vertically slidably arranged inside the pipe segment 1, and a spring is provided on the upper part for resetting, and a clamping block 25 is arranged above the rotating ring 2. The clamping block 25 can rotate to move upward against the lifting column 26 and then reset downward, preventing the rotating ring 2 from resetting. Finally, the extrusion valve 19 of the present invention is introduced. The extrusion valve 19 of the present invention is fixedly arranged on the pipe segment 1. In order to facilitate the display of the present invention, the specification is attached. Figure 7The figure shows a suspended state, which is actually motionless, and an extrusion cylinder 18 is slidably provided on one side of the extrusion valve 19, and glue is stored inside the extrusion cylinder 18. An extrusion tube 20 is slidably provided on the right side of the extrusion cylinder 18. One side of the extrusion tube 20 is in a sharp shape, and on the right side of the extrusion cylinder 18 is a film seal (for example, a film on the top of a beverage bottle, or an insertion port on the top of a milk bottle has a sealing sheet), so that when the rotating ring 2 rotates, the extrusion tube 20 can be driven to be inserted toward the extrusion cylinder 18 and break the film seal. At this time, continued rotation will cause the extrusion cylinder 18 to move toward the extrusion valve 19 to achieve the setting of glue discharge. The extrusion tube 20 is a hard tube, and one side of the extrusion tube 20 is a hose 21. The hose 21 is transported in two directions, toward It is transported to the edge of the rotating ring 2 in the upper direction and transported to the docking rod 9 in the other direction to form glue air-dried and fixed.
