[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a pipe ring construction method, which includes step one: moving the assembly platform 201 to the vicinity of the pipe segment 300 and placing the pipe segment 300 on top of the assembly platform 201;

[0032] Placing the segment 300 on the assembly platform facilitates subsequent transportation of the segment. On the assembly platform 201, staff can inspect the segment 300 to confirm that it is the correct type, in good condition, and that the gasket is properly bonded. This prevents damaged segments 300 from being assembled, which could cause problems with the entire pipe ring later on.

[0033] Placing it on the assembly platform 201 also makes it easier for staff to clean the segments 300, ensuring that the segments 300 to be spliced ​​are clean. In particular, the waterstop strips of the segments 300 must not be covered with mud or sand. The presence of mud and sand may cause damage to the waterstop strips and lead to water leakage. At the same time, sand particles will cause stress concentration, which may cause the segments 300 to crack under stress.

[0034] Step 2: Adjust the orientation of the segment 300 to ensure that the segment 300 above the assembly platform 201 can be assembled smoothly;

[0035] The positions of the segments 300 placed on the assembly platform 201 and the required order of the segments 300 to be assembled are confirmed to ensure accuracy. During splicing, the positioning is ensured to be accurate and the flatness is controlled to prevent the connection between two segments 300 from intersecting and affecting the assembly quality.

[0036] Furthermore, the orientation of the segment 300 is adjusted so that the first protrusion 301 of the segment 300 placed on the assembly platform 201 corresponds to the first recess 302, and the first protrusion 301 is inserted into the first recess 302.

[0037] Furthermore, the first protrusion 301 is located on one side of the segment 300, and the first recess 302 is located on the side of the segment 300 corresponding to the first protrusion 301.

[0038] During assembly, mechanical equipment such as hand hoists and robotic arms are used for hoisting, and the positions are corrected manually to ensure that when the segments 300 are connected, the first protrusion 301 of one segment 300 is aligned with the first recess 302 of the other segment 300, and the first protrusion 301 is inserted into the first recess 302. It is ensured that there is no large gap between the two after insertion, and that the flatness of the connection is ensured.

[0039] Furthermore, the installation of the tunnel segments 300 on the assembly platform 201 allows for real-time inspection of the connection between the tunnel segments 300, ensuring that all connections meet the installation standards when they are assembled into a tunnel ring. If errors occur during installation, timely adjustments can be made, reducing the time required to adjust the tunnel segments 300 after installation errors, and greatly ensuring the tunneling efficiency of the tunnel boring machine.

[0040] Step 3: Fix the joints of the assembled pipe segments 300 and move the assembled pipe segments 300 to the center of the assembly platform 201;

[0041] After the segment 300 is assembled, since the segment 300 is located on the assembly platform 201, it is convenient for the staff to fix the connection of the segment 300 to ensure that the connection is firm and stable and to prevent leakage at the connection of the segment 300.

[0042] Effectively securing the segments 300 ensures their durability, increases their load-bearing capacity and seismic performance, and prevents loosening at the joints of the segments 300 when they are installed in the shaft.

[0043] Step 4: Transport the assembled tunnel segment 300 to the designated location next to the shaft via 201.

[0044] The assembled pipe segment 300 is transported to the shaft via the assembly platform 201. This allows the assembled pipe ring to be joined to the pipe ring already installed in the shaft using mechanical grippers at the shaft. Assembling the pipe segment 300 at a distance saves space at the shaft and allows for preparation of the necessary equipment for installation.

[0045] By assembling the segments on the splicing platform 201 before transportation, it is not necessary to move a large number of unspliced ​​segments 300, thereby reducing the possibility of damage to the segments 300 during transportation and ensuring the quality of the segments 300.

[0046] Furthermore, the segment 300 is transported to a designated location next to the shaft, and the segment 300 on the assembly platform 201 is moved into the shaft by a robot arm next to the shaft. The second recess 304 on the segment 300 is placed at the second protrusion 303 of the segment 300 in the shaft, and the connection is fixed.

[0047] Furthermore, the second protrusion 303 is located on the side of the segment 300 that is different from the first recess 302 and the first protrusion 301, and the second recess 304 is located on the side of the segment 300 that corresponds to the second protrusion 303.

[0048] During installation, it is necessary to ensure that the joint between the pipe ring to be installed and the pipe ring already installed is misaligned to ensure a stable connection. Place the second recess 304 on the pipe segment 300 on the second protrusion 303 of the pipe segment 300 in the shaft. Through the cooperation between the second recess 304 and the second protrusion 303, ensure that it is kept on the same axis as the pipe segment 300 in the shaft.

[0049] After installation, the connection between the second recess 304 and the second protrusion 303 needs to be fixed to ensure a stable connection.

[0050] Example 2

[0051] Reference Figures 1-4 This is the third embodiment of the present invention, which is based on the previous embodiment. This embodiment provides a transportation device, which includes a transportation component 100, the transportation component 100 including sleepers 102 and tracks 101 symmetrically fixed on the sleepers 102; and a carrying component 200, the carrying component 200 including an assembly platform 201 and a motor 202 disposed below the assembly platform 201; wherein, the carrying component 200 is used to transport the tunnel segments 300, and the transportation component 100 is used to ensure the movement trajectory of the carrying component 200.

[0052] The transport component 100 and the load-bearing component 200 enable the transport of the tunnel segment 300, while the motor 202 provides power for the movement of the assembly platform 201, allowing it to move smoothly.

[0053] Specifically, the bottom of the assembly platform 201 is symmetrically provided with two sets of connecting blocks 201a. Each set of connecting blocks 201a is rotatably connected to a rotating shaft 201b. Both ends of the rotating shaft 201b are fixedly connected to rollers 201c. The outer ring of the rotating shaft 201b is fixedly fitted with a first bevel gear 201e.

[0054] Furthermore, the roller 201c has an annular groove 201d at its center, which engages with the protrusion of the track 101.

[0055] Furthermore, the motor 202 is mounted on the bottom center of the assembly platform 201 via the mounting plate 202b, and the output end of the motor 202 is fixedly connected to the second bevel gear 202a via the roller 201c. The first bevel gear 201e meshes with the second bevel gear 202a.

[0056] The connecting block 201a provides the conditions for the installation of the rotating shaft 201b. The roller 201c supports the connecting block 201a. The first bevel gear 201e can mesh with the second bevel gear 202a. The motor 202 drives the connecting rod 202c to rotate, which in turn drives the second bevel gear 202a to rotate. At the same time, the rotation of the second bevel gear 202a can also drive the first bevel gear 201e to rotate, thereby driving the roller 201c to move on the track 101 to realize the transportation of the tube segment 300.

[0057] The annular groove 201d is designed to fit tightly with the track 101, limiting the position of the roller 201c relative to the track 101 and preventing derailment during movement.

[0058] Example 3

[0059] Reference Figures 1-4This is the third embodiment of the present invention, which is based on the second embodiment. This embodiment also includes two symmetrically curved transport components 100, each of which is provided with a bearing component 200, and a portion of the pipe segments 300 are placed on the assembly platform 201 in the bearing component 200, and the pipe segments 300 can be spliced ​​into a ring shape.

[0060] The track 101 is set in an arc shape and is laid in conjunction with the sleepers 102. It can change the running trajectory of the bearing component 200 and avoid the components required by the installed tunnel boring machine while changing the movement trajectory.

[0061] In use, different numbers of segments 300 can be assembled on the two supporting components 200 respectively. Then, when the two supporting components 200 meet, the pushing mechanism set above the assembly platform 201 combines the spliced ​​rings on the two assembly platforms 201 into a ring. Then, the two motors 202 are controlled to rotate at the same speed, so that the two assembly platforms 201 move at the same speed. When the assembly platform 201 moves to the designated position, the motors 202 are stopped. Then, the assembled segments 300 are installed by mechanical equipment.

[0062] Alternatively, a vertical track 101 leading to the mechanical equipment can be used. The end of the vertical track 101 is divided into multiple tracks 101, and each track 101 is equipped with a bearing component 200. The segments 300 can be spliced ​​at multiple locations. By controlling the time when different assembly platforms 201 reach the vertical track 101, the segment 300 can be quickly installed into the shaft.

[0063] Multiple tracks 101 can also be set up to reach the mechanical device accessories from different positions. The pre-assembled pipe segments 300 are transported above different load-bearing components 200. The speed of the motor 202 is controlled so that the two load-bearing components 200 reach the vicinity of the mechanical equipment at different or the same speed. The mechanical equipment then places the assembled pipe segments 300 into the shaft.

[0064] This solution not only accommodates tunnel boring machines with different excavation speeds but also avoids many already installed devices while achieving good transportation efficiency.
