Example Embodiment

[0018] EXAMPLES: In this embodiment, the rail transit shield tunnel tunnel line joint reinforcing device is used to achieve linkage between the Tong Double Tunnel Tubes between the track traffic, thereby increasing the overall performance between the two; especially the guaranteed shield Tunnel tubes occur, such as settling, misconduct, and the coinability between the Tao bed, avoiding security risks between the two due to intermounce.

[0019] like figure 1 As shown, the rail transit shield tunnel includes a shield tunnel sheet 5, and a hand hole used in the shield tunnel tube sheet 5 is provided. A reinforced concrete bed 3 is provided on the surface of the shield tunnel sheet 5, and the upper frame of the reinforced concrete Tu 3 is provided with a prefabricated reinforced concrete sleeper 2, and there is a rail 1 above the prefabricated reinforced concrete sleeper 2 for the rail transit train.

[0020] Combine Figure 1 to 3 As shown, the main body of the linkage reinforcing devic

Abstract

The invention relates to the technical field of track traffic tunnel ballast beds, in particular to a track traffic shield tunnel ballast bed connection reinforcing device and an application method thereof. The connection reinforcing device comprises a connecting rod and a connector, one end of the connecting rod is a hook part matched with a steel bar of a ballast bed, the other end of the connecting rod is connected with the connector, the connector can be fixedly connected with a hand hole of the shield tunnel segment, and reinforced connection between the ballast bed and the shield tunnel segment is achieved. The device has the advantages that reinforced connection between the track bed and the shield tunnel segment of the track traffic is achieved, and the connection performance and integrity between the track bed and the shield tunnel segment are improved on the basis that the tunnel segment structure is not damaged; a certain buffer adjustment amount can be formed between the ballast bed and the shield tunnel segment, the adaptability during operation is high, and potential safety hazards caused by disengagement between the ballast bed and the shield tunnel segment are avoided; and construction is convenient, installation is fast, and popularization is facilitated.
