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.
