Immersed tunnel final joint sectional type retaining device and dry-wet alternate construction method thereof
The invention belongs to the technical field of immersed tube tunnel engineering, and relates to an immersed tube tunnel final joint sectional type retaining device and a dry-wet alternate construction method thereof.The immersed tube tunnel final joint sectional type retaining device comprises a bracket prefabricated on the side face of a final joint; the top of the retaining assembly is flush with the top of the final joint, and the bottom of the retaining assembly is flush with the bottom of the final joint; the retaining assembly comprises a first retaining piece pre-buried on the underground diaphragm wall and a second retaining piece arranged opposite to the bracket, and the second retaining piece is composed of N independent retaining parts, wherein N is larger than or equal to 2. N first connecting pieces are preset on the first retaining piece, second connecting pieces with the same number as the first connecting pieces are preset on the second retaining piece, each first connecting piece corresponds to one second connecting piece in a one-to-one mode, and the first connecting pieces and the second connecting pieces are matched to form a connecting body so as to connect the first retaining piece and the second retaining piece. The underwater construction time is shortened, the construction process is simplified, the construction difficulty is reduced, and rapid and convenient construction of the final joint is achieved.
本发明属于沉管隧道工程技术领域，涉及一种沉管隧道最终接头分段式止退装置及其干湿交替施工方法，装置包括：牛腿，预制于最终接头侧面；止退组件，其顶部与最终接头顶部平齐，其底部与最终接头底部平齐；止退组件包括预埋在地下连续墙上的第一止退件和与牛腿相对设置的第二止退件，第二止退件由N,N≥2段独立的止退部组成；第一止退件上预设N个第一连接件，第二止退件上预设与第一连接件相同数量的第二连接件，每个第一连接件一一对应一个第二连接件，第一连接件与第二连接件配合形成连接体，以连接第一止退件和第二止退件。本发明减少水下施工时间，简化施工工艺，降低施工难度，实现最终接头的快速、方便施工。
