Combined retaining device for final joint of immersed tunnel 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 combined type retaining device and a dry-wet alternate construction method thereof.The device comprises a retaining part, a force transmission part and a supporting part, the retaining part is poured to an underground diaphragm wall and arranged opposite to a bracket prefabricated on a final joint, and the force transmission part is connected with the supporting part; the distance L from the top of the retaining piece to the horizontal plane meets the condition that L is greater than or equal to H-h + l, so that the final joint is undocked and mounted when the final joint is constructed; the force transmission piece is arranged between the retaining piece and the bracket; the force transmission part comprises a first force transmission part, a second force transmission part and a third force transmission part which are connected in sequence, the first force transmission part is used for being in contact connection with the underground diaphragm wall, and the third force transmission part is used for being in matched connection with a steel cofferdam installed above the final joint; the supporting piece is used for connecting the upper portion of the force transmission piece and the underground diaphragm wall. The construction technology of the retaining device is simplified, the construction difficulty is reduced, rapid and convenient construction of the final joint is achieved, and the construction period is shortened.
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组合式止退装置及其干湿交替施工方法，装置包括止退件、传力件和支撑件，止退件浇筑于地下连续墙处，与预制于最终接头的牛腿相对设置，止退件顶部至水平面的距离L满足条件L≥H‑h+l，以在施工最终接头时使最终接头出坞安装；传力件设置于止退件与牛腿之间；传力件包括顺序连接的第一传力部、第二传力部和第三传力部，第一传力部用于与地下连续墙接触连接，第三传力部用于与安装在最终接头上方的钢围堰配合连接；支撑件用于连接传力件上部与地下连续墙。本发明简化了止退装置的施工工艺，降低了施工难度，实现最终接头的快速、方便施工，缩短了工期。
