Construction method of lake reinforced concrete immersed tunnel
A construction method of a lake reinforced concrete immersed tube tunnel belongs to the technical field of lake tunnel construction, and comprises the following steps: building immersed tube dry docks at one end or two ends corresponding to the lake reinforced concrete immersed tube tunnel to be constructed, and manufacturing reinforced concrete immersed tube joints to be subjected to floating transportation and installation and reinforced concrete immersed tube joints to be subjected to floating transportation and installation; the manufacturing method comprises the following steps: manufacturing a reinforced concrete immersed tube joint to be subjected to floating transportation and installation; water injection pipe valves arranged on one side or two sides in the length direction and used for injecting water into a tunnel pipe cavity and reinforced concrete immersed pipe joints arranged on the upper surface in the length direction and communicated with the tunnel pipe cavity are manufactured in immersed pipe dry docks corresponding to one end and/or two ends of the lake reinforced concrete immersed pipe tunnel to be constructed. A water stop belt is installed on the end face of one end of the obtained reinforced concrete immersed tube joint; and opening the gate of the immersed tube dry dock to discharge water. The construction efficiency is high, the construction period of the whole project is shortened, project investment is correspondingly saved, and normal navigation of the lake water area cannot be affected by construction.
一种湖泊钢筋混凝土沉管隧道的施工方法，属于湖泊隧道施工技术领域，包括在对应于所要构建湖泊钢筋混凝土沉管隧道的一端或两端建筑沉管干坞、制作待浮运安装的钢筋混凝土沉管管节和浮运安装钢筋混凝土沉管管节；制作待浮运安装的钢筋混凝土沉管管节包括的步骤：在对应于所要构建的湖泊钢筋混凝土沉管隧道的一端和/或两端的沉管干坞内制作在长度方向的一侧或两侧设置用于向隧道管腔内注水的注水管阀以及在长度方向的上表面设置与隧道管腔相通的钢筋混凝土沉管管节；对得到的钢筋混凝土沉管管节的一端端面安装止水带；对沉管干坞开闸放水。具有施工效率高，缩短整个工程的施工周期、相应节省工程投资，不会因施工影响湖泊水域的正常通航。
