Construction method and structure of immersed tube tunnel and shield tunnel
The invention relates to a construction method and structure of an immersed tunnel and a shield tunnel. The construction method comprises the following steps that an immersed tunnel line and a shield tunnel line are planned; the immersed tunnel is constructed on the immersed tunnel line; constructing a cofferdam at the junction of the immersed tunnel line and the shield tunnel line; an open-cut tunnel is excavated in the cofferdam, so that the open-cut tunnel is communicated with the immersed tube tunnel; a shield tunnel is constructed on the shield tunnel line; the joints of the open cut tunnel, the immersed tube tunnel and the shield tunnel are constructed; and after the backfilled cofferdam is covered with soil, the cofferdam is dismantled, and then construction is completed. The method has the beneficial effects that the immersed tube tunnel and the shield tunnel are communicated through the open-cut tunnel, and the problems that the immersed tube tunnel and the shield tunnel are directly communicated, so that the size of the immersed tube tunnel is set to be far larger than the actually-needed size, and then water leakage and poor durability occur at the joint of the shield tunnel and the immersed tube tunnel are solved.
本发明涉及一种沉管隧道与盾构隧道的施工方法及结构，包括以下步骤：规划沉管隧道线路及盾构隧道线路；在沉管隧道线路施工沉管隧道；在沉管隧道线路与盾构隧道线路的交界处施工围堰；在围堰内开挖明挖隧道，使明挖隧道与沉管隧道连通；在盾构隧道线路施工盾构法隧道；对明挖隧道与沉管隧道及盾构法隧道的连接处进行施工；在回填围堰内覆土后，拆除围堰，即，完成施工。本发明的有益效果在于：利用明挖隧道将沉管隧道与盾构隧道连通，避免了直接将沉管隧道与盾构隧道连通导致沉管隧道的尺寸设置的远大于实际所需要的尺寸，进而导致盾构隧道和沉管隧道的连接处出现漏水及耐久性差的问题。
