[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] refer to Figure 1 and Figure 2 As shown, an embodiment of this application provides a tunnel positioning device 100, which includes a base 110, a movable column 120, a centering platform 130, and a support member 140. The tunnel positioning device 100 is used to place and install measuring equipment and is applied to the measurement of tunnel segments 200.

[0034] Specifically, in combination Figure 2 and Figure 3As shown, one side of the base 110 is fixedly installed at the edge position inside the tunnel segment 200. One end of the movable column 120 is hinged to the side of the base 110 away from the tunnel segment 200. The tunnel segment 200 has a certain curvature, and the base 110 is in an inclined state when installed inside the tunnel segment 200. The centering platform 130 is fixedly connected to the end of the movable column 120 away from the base 110. The centering platform 130 is used to place measuring equipment. A tunnel positioning device 100 is set at each underground pre-buried point to facilitate the installation of measuring equipment. The base 110 can be set at the edge position inside the tunnel segment 200 without affecting or obstructing the track operation in the tunnel segment 200. The base 110 is connected to the centering platform 130 through the movable column 120. The movable column 120 can be adjusted relative to the base 110 so that the centering platform 130 always remains in a horizontal state.

[0035] In this embodiment, one end of the support member 140 is movably connected to the middle of the movable column 120, and the end of the support member 140 away from the movable column 120 is connected to the tunnel segment 200. The support member 140 and the movable column 120 are set at an angle. Correspondingly, the movable column 120 is supported by the support member 140 after adjustment. The support member 140 and the movable column 120 are set at an angle and connected to the tunnel segment 200 to ensure the stability and flexibility of the tunnel positioning device 100, prevent the centering error caused by the temporary installation of the tripod, so as to meet the measurement standards of the measuring equipment and thus ensure the measurement accuracy of the measuring equipment. The measuring equipment is installed on the centering platform 130 or removed from the centering platform 130 to improve the efficiency of the measurement operation.

[0036] Understandably, tunnel segment 200 is a crucial component in tunnel construction, primarily used to support and protect the tunnel structure. It is typically made of reinforced concrete, possessing high strength and durability. During tunnel construction, the segments are assembled into a ring structure, forming the tunnel lining. This lining effectively resists external pressure, ensuring the tunnel's safety and stability. The installation of tunnel segment 200 usually employs the shield tunneling method; during the advancement of the tunnel boring machine, the tunnel segments 200 are installed sequentially to form the complete tunnel structure. Internal measurement of tunnel segment 200 refers to the relevant testing of the geometric shape, dimensional accuracy, and assembly quality of the prefabricated segments that constitute the tunnel lining, ensuring they meet design requirements and can be safely and stably assembled into the tunnel structure.

[0037] refer to Figure 2 and Figure 4As shown, the tunnel positioning device 100 has a first direction X. For example, the first direction X is defined as the height direction of the tunnel positioning device 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts of the tunnel positioning device 100 and should not be construed as limiting this application.

[0038] In one embodiment, alternatively, referencing Figure 3 As shown, the tunnel positioning device 100 also includes a connector 150. The base 110 is hinged to the movable column 120 via the connector 150, meaning the movable column 120 can move relative to the base 110 via the connector 150. This allows the movable column 120 to be adjusted according to the position and angle of the centering platform 130. The relative movement of the movable column 120 keeps the centering platform 130 horizontal, facilitating the installation of measuring equipment on the centering platform 130 and ensuring the measurement accuracy of the measuring equipment. For example, the measuring equipment can be a total station, with the tunnel positioning device 100 acting as a support, allowing the total station to be installed on the centering platform 130.

[0039] In one embodiment, alternatively, referencing Figure 2 and Figure 4 As shown, the base 110 is provided with a plurality of mounting holes 111, and the tunnel segment 200 is provided with a corresponding pre-embedded bolt 210, with each mounting hole 111 corresponding to one pre-embedded bolt 210.

[0040] In summary, the tunnel positioning device 100 can be installed at each underground pre-buried point to facilitate the installation of measuring equipment. The base 110 can be set at the edge of the tunnel segment 200 without affecting or obstructing the track operation in the tunnel segment 200. The base 110 is connected to the centering platform 130 through the movable column 120. The movable column 120 can be adjusted relative to the base 110 to keep the centering platform 130 in a horizontal state. After adjustment, the movable column 120 is supported by the support member 140. The support member 140 and the movable column 120 are set at an angle and connected to the tunnel segment 200 to ensure the stability and flexibility of the tunnel positioning device 100 and prevent centering errors caused by temporary tripod installation, so as to meet the measurement standards of the measuring equipment and thus ensure the measurement accuracy of the measuring equipment. The measuring equipment can be installed on or removed from the centering platform 130 to improve the efficiency of the measurement operation.

[0041] refer to Figure 1 and Figure 2As shown, an embodiment of this application provides another tunnel positioning device 100, which includes a base 110, a movable column 120, a centering platform 130 and a support member 140. The tunnel positioning device 100 is used to place and install measuring equipment and is applied to the measurement of tunnel segments 200.

[0042] Specifically, in combination Figure 2 and Figure 3 As shown, one side of the base 110 is fixedly installed at the edge position inside the tunnel segment 200. One end of the movable column 120 is hinged to the side of the base 110 away from the tunnel segment 200. The tunnel segment 200 has a certain curvature, and the base 110 is in an inclined state when installed inside the tunnel segment 200. The centering platform 130 is fixedly connected to the end of the movable column 120 away from the base 110, and the centering platform 130 is used to place measuring equipment. One end of the support member 140 is movably connected to the middle of the movable column 120, and the end of the support member 140 away from the movable column 120 is connected to the tunnel segment 200. The support member 140 and the movable column 120 are set at an angle. Correspondingly, a tunnel positioning device 100 is provided at each underground pre-embedded point to facilitate the installation of measuring equipment. The base 110 can be set at the edge position inside the tunnel segment 200 without affecting or obstructing the track operation within the tunnel segment 200. The base 110 is connected to the centering platform 130 via the movable column 120. The movable column 120 is adjustable relative to the base 110, ensuring that the centering platform 130 remains horizontal. After adjustment, the movable column 120 is supported by the support member 140. The support member 140 and the movable column 120 are set at an angle and connected to the tunnel segment 200, ensuring the stability and flexibility of the tunnel positioning device 100 and preventing centering errors caused by temporary tripod installation. This facilitates compliance with the measurement standards of the measuring equipment, thereby ensuring the measurement accuracy of the measuring equipment. The measuring equipment can be installed on or removed from the centering platform 130, improving the efficiency of the measurement operation.

[0043] In one embodiment, alternatively, referencing Figure 3 As shown, the tunnel positioning device 100 also includes a connector 150. The base 110 is hinged to the movable column 120 via the connector 150, meaning the movable column 120 can move relative to the base 110 via the connector 150. This allows the movable column 120 to be adjusted according to the position and angle of the centering platform 130. The relative movement of the movable column 120 keeps the centering platform 130 in a horizontal position, facilitating the installation of measuring equipment on the centering platform 130 and ensuring the measurement accuracy of the measuring equipment. For example, the measuring equipment can be a total station. The tunnel positioning device 100 acts as a support, similar to a bracket, allowing the total station to be installed on the centering platform 130.

[0044] The base 110 and the movable column 120 have a gap 160, which allows the movable column 120 to have a certain amount of room to move, so that the movable column 120 can be adjusted to keep the centering platform 130 in a horizontal state.

[0045] Furthermore, the connector 150 is a ball joint structure, with a gap formed between the base and the movable column. The connector is positioned at this gap. The ball joint structure allows for multi-directional relative rotation between the movable column 120 and the base 110. The movable column 120 and the base 110 can rotate freely within a certain range while maintaining structural stability and strength. For example, the ball joint structure 150 includes a base 110, a cover, and a cue with a rotating ball. The cover has a receiving cavity, the base 110 has a hemispherical cavity for inserting the rotating ball, and the cover has a through hole in the center for the cue to pass through. Its inner wall forms an arc surface that fits and supports the rotating ball, allowing it to flexibly withstand pressure from different directions and enabling the cue with the rotating ball to adjust its angle or rotate in multiple directions.

[0046] In one embodiment, alternatively, referencing Figure 2 As shown, there are two support members 140, which are support rods. Along the first direction X, the two support rods are respectively positioned on opposite sides of the movable column 120. The two ends of the support rods are connected to the movable column 120 and the tunnel segment 200, respectively. Correspondingly, the support rods and the movable column 120 are connected by hinges, forming a triangular support structure. Furthermore, the two support rods form an "eight"-shaped or "X"-shaped layout. The triangular structure disperses the load on the movable column 120, preventing it from tilting due to excessive load. The support members 140 and the movable column 120 jointly bear the weight of the measuring equipment and external loads, ensuring no shaking or displacement during the measurement process.

[0047] In one embodiment, optionally, combining Figure 3 and Figure 4 As shown, an angle adjustment mechanism 170 is provided at the hinge joint between the support member 140 and the movable column 120. This mechanism is used to adjust the angle between the support member 140 and the movable column 120 or to lock the hinge position of the support member 140 and the movable column 120. The angle adjustment mechanism 170 has a large adjustment range and precise control. For example, the angle between the support member 140 and the movable column 120 can be any value between 30° and 150°. Specifically, the angle between the support member 140 and the movable column 120 can be 30°, 45°, 750°, 90°, 100°, 120°, or 150°.

[0048] Optionally, the angle adjustment mechanism 170 includes a locking bolt that passes through the hinge shaft between the movable column 120 and the support member 140 to fix the included angle. The locking bolt can be loosened by a wrench or a special tool, at which point the end of the bolt separates from the inner wall of the hinge shaft, and the support member 140 can be freely adjusted. Alternatively, the locking bolt can be tightened, and the end of the bolt is pressed between the inner wall of the hinge shaft and the threaded hole of the movable column 120, thereby fixing the relative angle between the support member 140 and the movable column 120 by friction.

[0049] In one embodiment, alternatively, referencing Figure 2 and Figure 4 As shown, the base 110 is provided with a plurality of mounting holes 111, and the tunnel segment 200 is correspondingly provided with embedded bolts 210, with each mounting hole 111 corresponding to one embedded bolt 210. For example, the base 110 is provided with four mounting holes 111, and the corresponding number of embedded bolts 210 is four.

[0050] Furthermore, the gap between the base 110 and the tunnel segment 200 is filled with concrete to facilitate the placement and fixing of the pre-embedded bolts 210, which are used to place and fix the base 110, so that the base 110 is kept basically horizontal or the angle between the base 110 and the horizontal plane is reduced, which is beneficial for the subsequent leveling operation of the platform 130.

[0051] In one embodiment, alternatively, such as Figure 2 and Figure 3 As shown, the end of the support member 140 away from the movable column 120 is provided with a detachable fixing buckle. The fixing buckle is connected to the tunnel segment 200. The support member 140 can be disassembled and assembled through the fixing buckle, so as to separate the support member 140 and the tunnel segment 200. In addition, the support member 140 is hinged to the tunnel segment 200 so that the support member 140 can support the movable column 120.

[0052] In one embodiment, optionally, the centering platform 130 is equipped with a bubble level. The bubble level is used to monitor the horizontal status of the measuring equipment in real time. After adjusting the position and angle of the centering platform 130 on which the measuring equipment is installed, the operator observes the position of the bubble level and ensures that the bubble is located at the center scale line of the level tube. For example, the bubble level can be a high-precision glass circular level or a long level. The operator confirms whether the measuring equipment has been centered and meets the measurement standards by visually observing the bubble level, and makes timely corrections to ensure that the measuring equipment meets the measurement standards and guarantees the measurement accuracy of the measuring equipment.

[0053] An embodiment of this utility model also provides a tunnel measurement system, including the tunnel positioning device 100 in the above embodiment. The tunnel measurement system including the tunnel positioning device 100 has all the beneficial effects of the tunnel positioning device 100, which will not be described in detail here.

[0054] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0055] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
