Shield tunnel ballast bed connecting structure and mounting method
The invention discloses a shield tunnel ballast bed connecting structure and a mounting method, solves the problem that a ballast bed is easy to be separated from a shield tunnel segment in the prior art, and has the beneficial effects that the problem of glass separation between the tunnel shield segment and the ballast bed is avoided, and a channel is pre-buried by fully utilizing the shield tunnel segment. According to the specific scheme, the shield tunnel ballast bed connecting structure comprises a reinforcing piece located in a ballast bed, the reinforcing piece is located on the inner side of a shield tunnel segment, the reinforcing piece is connected with the shield tunnel segment through a connecting piece, and the reinforcing piece and part of the connecting piece are of an integrated structure with the ballast bed in the ballast bed pouring process; the connecting piece is in a T shape, the head of the T-shaped connecting piece is inserted into a pre-buried channel of the shield tunnel segment, the head of the connecting piece is locked by the first fastening piece, and the connecting piece is provided with the second fastening piece on at least one side of the reinforcing piece.
本发明公开了一种盾构隧道道床连接结构及安装方法，解决了现有技术中存在道床容易同盾构隧道管片脱空的问题，具有避免隧道盾构管片与道床之间玻璃脱空的问题，充分利用盾构隧道管片预埋槽道的有益效果，具体方案如下：一种盾构隧道道床连接结构，包括位于道床内的加固件，加固件位于盾构隧道管片内侧，加固件同盾构隧道管片通过连接件连接，加固件和部分连接件在道床浇筑过程中与道床为一体结构；连接件为T型，T型连接件的头部插入盾构隧道管片的预埋槽道中，第一紧固件对连接件的头部进行锁紧，连接件在加固件的至少一侧安装有第二紧固件。
