Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine (TBM) engineering technology for rail transit, and more specifically, to a structure for storing TBM segments. Background Technology

[0002] Urban rail transit typically utilizes underground construction, and shield tunnels offer numerous advantages, leading to their widespread application in domestic rail transit projects. Shield tunnels boast high space utilization, achieving efficient traffic capacity within limited underground space, and have minimal impact on surface traffic during construction, as tunnel construction primarily takes place underground, reducing disruption to surface traffic. Furthermore, shield tunnels are relatively inexpensive, saving resources and costs in long-term operation and maintenance. Therefore, shield tunnel technology has become an ideal choice for urban rail transit construction, providing crucial support for the expansion and optimization of urban transportation networks.

[0003] Furthermore, after the tunnel segments are prefabricated in the factory, they are transported to the construction site for temporary storage. However, the site often lacks proper planning for the tunnel segments, which can easily lead to problems such as missing corners, cracks, or surface damage during storage. As a result, during subsequent tunnel assembly and long-term operation, these issues can gradually develop into potential water leakage hazards, directly impacting the operational safety of urban rail transit.

[0004] In addition, the industry often uses traditional simple supports or direct stacking to store tunnel segments. When multiple tunnel segments are stacked or stored side by side, they are prone to direct contact. During handling or environmental vibration, they are prone to collisions and scratches, resulting in quality problems such as broken corners and surface cracks, thereby reducing the quality of the tunnel segments.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a shield tunnel segment storage structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows: A shield tunnel segment storage structure includes: a supporting base rod; several supporting end plates disposed on the top of the supporting base rod, and the several supporting end plates are arranged linearly and equidistantly; a crossbar disposed on the common top of the several supporting end plates; side rods symmetrically disposed on the top of the supporting base rod and at both ends of the crossbar; several partition rods disposed between two side rods; and an arc-shaped placement frame disposed between two adjacent partition rods, and the top side of the partition rod and the top side of the side rod are fixedly connected by the arc-shaped placement frame; and the supporting base rod, crossbars, side rods and arc-shaped placement frame are fixedly connected to form a U-shaped frame structure.

[0008] Furthermore, in order to ensure the safe spacing between segments and avoid excessive compression of space, and to increase space utilization, the crossbars, several partition bars, two side bars, several arc-shaped placement frames, and several support end plates are fixedly connected to form an inverted I-shaped structure.

[0009] Furthermore, in order to improve the support and stability of the arc-shaped placement rack, a partition space for the placement rack is formed between one side wall of the side rod and one side of the partition rod.

[0010] Furthermore, in order to ensure the stable storage of the tunnel segments and reduce friction, pressure and deformation, and to ensure the integrity of the shape and structure of the tunnel segments, the curvature inside the arc-shaped placement frame is the same as the arc-shaped surface on the outer circumference of the tunnel segment.

[0011] Furthermore, in order to withstand and distribute pressure from all directions, prevent structural tilting or deformation, reduce redundant support elements, and enhance support strength, foot plates are installed at the bottom of the support base rods; diagonal braces are installed at the top of the foot plates and on one side of the support end plates. The side rods, support end plates, and diagonal braces are fixedly connected to form a triangular reinforcement structure.

[0012] The beneficial effects of this utility model are as follows: 1) This utility model can flexibly increase the number of supporting base rods and adjust the vertical spacing according to the actual length, curvature and storage quantity of the shield tunnel segments, so as to adapt to the storage needs of different specifications of tunnel segments, thereby improving the utilization rate of site space, and at the same time, the whole structure is easy to move.

[0013] 2) By placing the shield tunnel segments with their arc surfaces facing each other inside multiple arc-shaped placement frames, the shield tunnel segments can be subjected to uniform force. At the same time, multiple separator bars are used to separate and store the shield tunnel segments, thereby avoiding problems such as collisions and scratches during handling or vibration, and thus reducing quality damage such as edge breakage and surface cracks.

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, a shield tunnel segment storage structure is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1 and Figure 2 As shown, a shield tunnel segment storage structure according to an embodiment of the present invention includes: a supporting base rod 1; a plurality of supporting end plates 2, disposed on the top of the supporting base rod 1, and the plurality of supporting end plates 2 are arranged linearly at equal intervals; a crossbar 3, disposed on the common top of the plurality of supporting end plates 2; side rods 4, symmetrically disposed on the top of the supporting base rod 1 and at both ends of the crossbar 3; a plurality of partition rods 5, disposed between two side rods 4; an arc-shaped placement frame 6, disposed between two adjacent partition rods 5, and the top side of the partition rod 5 and the top side of the side rod 4 are fixedly connected by the arc-shaped placement frame 6; and a U-shaped frame structure is formed by the fixed connection between the supporting base rod 1, the crossbar 3, the side rods 4 and the arc-shaped placement frame 6.

[0020] By utilizing the above-mentioned technical solution of this utility model, the number of supporting base rods 1 can be flexibly increased and the vertical spacing adjusted according to the actual length, curvature, and storage quantity of the tunnel lining segments. This adapts to the storage needs of segments of different specifications, thereby improving the utilization rate of site space and facilitating overall relocation. By placing the arc-shaped surfaces of the tunnel lining segments correspondingly inside multiple arc-shaped placement racks 6, the force on the tunnel lining segments can be evenly distributed. At the same time, multiple separator rods 5 are used to separate and store the tunnel lining segments, thereby avoiding collisions and scratches during handling or vibration, and reducing quality damage such as edge breakage and surface cracks.

[0021] In one embodiment, the support base rod 1, the crossbar 3, the side rod 4, and the arc-shaped placement frame 6 are fixedly connected to form a U-shaped frame structure, thereby providing strong longitudinal and lateral support and enhancing the resistance to deformation, and better distributing the weight of the segments and reducing the load-bearing pressure of a single part.

[0022] Working principle of the support base rod 1: Two side rods 4 are symmetrically fixedly connected to the top of the support base rod 1. The top ends of the side rods 4 are fixedly connected to both ends of the crossbar 3 and the end of the arc-shaped placement frame 6, respectively, forming a U-shaped frame structure of the storage rack. The U-shaped frame structure, through the symmetrically arranged side rods 4, constrains the lateral displacement of the shield tunnel segments from both sides, preventing the segments from shifting during storage. At the same time, the side rods 4 are connected to the top of the diagonal rods 8, which can evenly distribute the reinforcing force transmitted by the diagonal rods to the entire U-shaped frame structure, thereby offsetting the lateral overturning force of the storage rack caused by carrying tunnel segments or external disturbances.

[0023] In one embodiment, for the aforementioned crossbar 3, the crossbar 3, several partition bars 5, two side bars 4, several arc-shaped placement frames 6, and several support end plates 2 form an inverted I-shaped structure, thereby ensuring a safe distance between the segments and avoiding excessive compression of space, and increasing space utilization.

[0024] The working principle of the separator bars 5: Several separator bars 5 are located between two side bars 4. Several arc-shaped placement frames 6 are correspondingly installed on the top sides of adjacent separator bars 5 and one side of the top of side bars 4. Horizontal bars 3 are connected to the tops of the two side bars 4. At the same time, several support end plates 2 are fixed at the bottom to the support base bar 1 and the side bars 4, together forming an inverted I-shaped structure. In the inverted I-shaped structure, the horizontal bars 3, the arc-shaped placement frames 6, and the multiple separator bars 5 work together to form a stable upper support layer. The two ends of the horizontal bars 3 are connected to the two side bars 4, realizing the integrity of the upper structure, while the arc-shaped placement frames 6 bear the weight of the tunnel segments. The support end plates 2 provide lateral support and lateral constraint to the side bars 4 and the multiple separator bars 5 from the bottom, limiting the deformation of the side bars 4 due to bearing the weight of the tunnel segments. This allows the separator bars 5 to divide the independent storage area of ​​a single tunnel segment, preventing damage caused by mutual compression between tunnel segments. At the same time, the structural mechanical stability of the horizontal bars 3, the multiple separator bars 5, the two side bars 4, and the multiple support end plates 2 ensures the overall load-bearing safety and structural stability of the storage rack.

[0025] In addition, multiple support end plates 2 are uniformly fixedly connected to the top of the support base rod 1, and the top of the multiple support end plates 2 are jointly fixedly connected to the same crossbar 3. The multiple support end plates 2 prevent the crossbar 3 from local bending deformation due to bearing the weight of the tunnel segments. The two ends of the crossbar 3 are respectively fixedly connected to the outer walls of the two side rods 4, thereby ensuring the load-bearing stability of the crossbar 3.

[0026] In one embodiment, for the side rod 4, one end of the side wall of the side rod 4 and one side of the partition rod 5 form a partition space for the placement rack, thereby improving the support and stability of the arc-shaped placement rack.

[0027] The working principle of the side bar 4: Multiple partition bars 5 are evenly and fixedly connected to the top of the crossbar 3, and multiple arc-shaped placement frames 6 are evenly and fixedly connected to the top of the crossbar 3. The outer walls of the two ends of the multiple arc-shaped placement frames 6 are fixedly connected to the outer walls of the multiple partition bars 5 and the two side bars 4 respectively. The multiple partition bars 5 can form a partition space between the multiple arc-shaped placement frames 6, which can limit different shield tunnel segments to independent areas, avoid direct contact when storing multiple shield tunnel segments, prevent collisions and scratches during handling or vibration, and reduce quality problems such as edge and corner damage and surface cracks of the segments.

[0028] In one embodiment, the arcuate placement frame 6 has the same curvature inside as the arcuate surface outside the circumference of the tunnel segment, thereby ensuring the stable storage of the segment and reducing friction, pressure and deformation, and ensuring the integrity of the shape and structure of the tunnel segment.

[0029] In one embodiment, the foot plate 7 is located at the bottom of the supporting base rod 1; the diagonal rod 8 is located at the top of the foot plate 7 and on one side of the supporting end plate 2. The side rod 4, the supporting end plate 2, and the diagonal rod 8 are fixedly connected to form a triangular reinforcement structure, which can withstand and disperse pressure from all directions, prevent structural tilting or deformation, reduce redundant support elements, and enhance support strength.

[0030] The working principle of foot plate 7: Multiple diagonal braces 8 are arranged in pairs, forming a triangular reinforcement structure in conjunction with foot plate 7. This triangular reinforcement structure enhances the connection strength between foot plate 7 and the upper frame, and resists tilting forces caused by the weight of the tunnel segments or external disturbances. Simultaneously, the bottom of the side brace 4, through the diagonal braces 8 and foot plate 7, forms a triangular reinforcement structure. This triangular reinforcement structure prevents the foot plate 7 from shifting during placement, thereby improving the storage rack's anti-tipping capability.

[0031] Furthermore, the bottom of the support base rod 1 is connected to the support assembly, and the support assembly includes multiple foot plates 7. The bottom of the support base rod 1 is fixedly connected to the top of the multiple foot plates 7, and two diagonal rods 8 are fixedly connected to the top of each foot plate 7. The outer walls of three support end plates 2 and the outer walls of two side rods 4 are respectively fixedly connected to the top of the multiple diagonal rods 8.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In practical applications, workers add more support base rods 1 according to the length and number of shield tunnel segments. Multiple support base rods 1 provide support at the bottom, and the arrangement distance of the support base rods 1 can be adjusted according to actual use. When storing shield tunnel segments, the curved surface of the shield tunnel segment is placed inside multiple uniform vertical curved placement frames 6. The shield tunnel segments are supported by multiple curved placement frames 6. At the same time, the side rods 4, multiple support end plates 2 and cross rods 3 provide support force to multiple curved placement frames 6 to ensure stability during placement. At the same time, multiple separator rods 5 can separate the stored shield tunnel segments. During the support process, multiple foot plates 7 contact the flat ground to provide overall support force, and multiple diagonal rods 8 increase the stability of the foot plates 7 and the whole structure.

[0034] In summary, by utilizing the above-mentioned technical solution of this utility model, the number of supporting base rods 1 can be flexibly increased and the vertical spacing adjusted according to the actual length, curvature, and storage quantity of the tunnel segments. This adapts to the storage needs of tunnel segments of different specifications, thereby improving the utilization rate of site space and facilitating overall relocation. By placing the tunnel segments with their arc surfaces facing each other inside multiple arc-shaped placement racks 6, the tunnel segments can be subjected to uniform force. At the same time, multiple dividing rods 5 are used to separate and store the tunnel segments, thereby avoiding collisions and scratches during handling or vibration, and reducing quality damage such as edge breakage and surface cracks.
