Description

Technical Field

[0001] The utility model relates to the field of shield tunnel segments, in particular to a lining structure of shield tunnel segments. Background Technique

[0002] Shield segments are the main assembled components in shield construction. They are the innermost barriers of the tunnel, bearing the functions of resisting soil pressure, groundwater pressure, and some special loads. Shield segments are the permanent lining structures of shield tunnels. The quality of shield segments is directly related to the overall quality and safety of the tunnel, affecting the waterproof performance and durability of the tunnel.

[0003] During the installation of existing shield tunnel segments, first, the shield tunnel segments are moved to the corresponding positions for splicing by a ring manipulator, and then the staff fixes the shield tunnel segments by means of bolts.

[0004] However, when operating the above method, due to slight deviations during the splicing of shield tunnel segments, when the staff fixes the bolts, it is not easy to insert the bolts into the bolt holes, and the position needs to be continuously adjusted for bolt fixation, which brings inconvenience to the installation of the staff. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a lining structure of shield tunnel segments to solve the technical problem that slight deviations occur during the splicing of shield tunnel segments, resulting in difficulty in inserting bolts into bolt holes.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A lining structure of shield tunnel segments, including shield segments and bolt pipes. An inner groove is provided on the inner wall of the shield segment, and bolt holes are provided on the inner wall of the inner groove. A first bolt head is fixedly arranged at one end of the bolt pipe, a second bolt head is fixedly arranged at the other end of the bolt pipe, a nut is sleeved on the outer wall of the bolt pipe, and a gasket is sleeved on the outer wall of the bolt pipe. The diameters of both ends of the bolt hole are larger than the diameter of the middle part, and the diameter of the bolt pipe near the second bolt head is smaller than the diameter near the first bolt head.

[0007] By adopting the above technical solution, when the staff installs the shield tunnel segments, after moving the shield tunnel segments to the corresponding positions by a ring manipulator, the worker inserts the second bolt head into the bolt hole. The aperture of the second bolt head is smaller, and it can be easily inserted into the bolt hole with a larger aperture, so that the staff does not need to adjust the bolt position back and forth for fixation.

[0008] The utility model is further arranged such that a first groove is provided at the top of the shield segment, and a convex block is fixed at the bottom of the shield segment.

[0009] By adopting the above technical solution, the bump at the bottom of the shield segment will be clamped in the first groove, fixing it up and down so that it will not loosen easily.

[0010] The present utility model is further configured such that a protrusion is fixed on one side of the shield segment, and a second groove is provided on the other side of the shield segment.

[0011] By adopting the above technical solution, it is easier to dock the two shield segments when they are fixed, and they will not separate easily left and right.

[0012] The present utility model is further configured such that a sealing strip is fixed on one side of the shield segment.

[0013] By adopting the above technical solution, the docking is tighter, and the waterproof effect is better, and the shield segment will not loosen due to the influence of water stains.

[0014] The present utility model is further configured such that the inner wall of the inner groove is trapezoidal.

[0015] By adopting the above technical solution, the bolt tube can be inserted more easily, and it is more convenient for the nut to tighten and fix it.

[0016] In summary, the present utility model mainly has the following beneficial effects:

[0017] The present utility model solves the problem that when splicing the shield tunnel segments, due to slight deviations, the staff needs to continuously adjust the bolts for fixing. When the staff installs the shield tunnel segments, after moving the shield tunnel segments to the corresponding positions by the annular manipulator, the worker inserts the second bolt head into the bolt hole. The aperture of the second bolt head is smaller, and it can be easily inserted into the bolt hole with a larger aperture, so that the staff does not need to adjust the bolt position back and forth for fixing.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0024] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0025] A lining structure for a shield tunnel segment, as Figure 1 - Figure 4 shown, includes a shield segment 1 and a bolt pipe 4. An inner groove 2 is provided on the inner wall of the shield segment 1, and a bolt hole 3 is provided on the inner wall of the inner groove 2. A first bolt head 5 is fixedly provided at one end of the bolt pipe 4. When installing the shield segment 1, first, the shield segment 1 is moved to the corresponding position by a ring manipulator. At this time, the protrusion 9 on one side of the shield segment 1 will be engaged in the second groove 12 on one side of another shield segment 1 for preliminary fixation. Subsequently, the two adjacent shield segments 1 are preliminarily spliced and aligned. A second bolt head 6 is fixedly provided at the other end of the bolt pipe 4. A nut 7 is sleeved on the outer wall of the bolt pipe 4, and a gasket 8 is sleeved on the outer wall of the bolt pipe 4. The diameters of both ends of the bolt hole 3 are larger than the diameter of the middle part. The end of the second bolt head 6 is inserted into the bolt hole 3. Since the aperture of the second bolt head 6 is smaller than that of the first bolt head 5, it can be relatively easily inserted into the bolt hole 3. Subsequently, the bolt pipe 4 will pass through the bolt hole 3 provided inside the shield segment 1. Finally, the bolt pipe 4 is tightened by the nut 7 to achieve the effect of fixing the adjacent shield segments 1. The diameter of the bolt pipe 4 near the second bolt head 6 is smaller than the diameter near the first bolt head 5.

[0026] Please refer to Figure 1 - Figure 3 , a first groove 10 is provided at the top of the shield segment 1, and a convex block 11 is fixed at the bottom of the shield segment 1. When splicing the two shield segments 1, the convex block 11 at the bottom of the shield segment 1 will be engaged in the first groove 10 to fix it up and down so that it will not easily loosen.

[0027] Please refer to Figure 1 and Figure 2, a protrusion 9 is fixed on one side of the shield segment 1, and a second groove 12 is formed on the other side of the shield segment 1. When two shield segments 1 are aligned left and right, the protrusion 9 on one side of the shield segment 1 will be docked with the second groove 12 on one side of the other shield segment 1, making it easier to dock when the two shield segments 1 are fixed, and they will not easily separate left and right.

[0028] Please refer to Figure 2 , a sealing strip 13 is fixed on one side of the shield segment 1. After the shield segments 1 are docked, the sealing strip 13 provided on one side makes the docking tighter and has a better waterproof effect, and the shield segment 1 will not become loose due to the influence of water stains.

[0029] Please refer to Figure 1 - Figure 3 , the inner wall of the inner groove 2 is trapezoidal. When fixing the shield segment 1 with the bolt tube 4, the trapezoidal inner wall setting can make it easier for the bolt tube 4 to be inserted, and it is more convenient for the nut 7 to tighten and fix it.

[0030] The working principle of the present utility model is as follows: the aperture of the first bolt head 5 is larger than that of the second bolt head 6 and the aperture of the bolt tube 4. When installing the shield segment 1, first, the shield segment 1 is moved to the corresponding position by the annular manipulator. At this time, the protrusion 9 on one side of the shield segment 1 will be engaged in the second groove 12 on one side of the other shield segment 1 for preliminary fixation. Subsequently, two adjacent shield segments 1 are initially spliced and aligned. After the alignment is completed, the staff fixes the two shield segments 1 with bolts. The end of the second bolt head 6 is inserted into the bolt hole 3. Since the aperture of the second bolt head 6 is smaller than that of the first bolt head 5, it can be easily inserted into the bolt hole 3. Subsequently, the bolt tube 4 will pass through the bolt hole 3 provided inside the shield segment 1. Finally, the bolt tube 4 is tightened with the bolt 7. At this time, the sealing strip 13 on one side of the shield segment 1 will make the sealing and waterproof effect between two adjacent shield segments 1 better, so as to achieve the effect of more tightly fixing adjacent shield segments 1.
