一种管节吊运沉放系统
摘要：
本实用新型涉及沉管隧道建设技术，特别涉及一种管节吊运沉放系统。沉放系统包括沉放驳，待安管节吊挂在所述沉放驳的下方，所述沉放驳上分别设有管节升降机构、管节平移机构和沉放驳平移机构；所述沉放驳平移机构用于控制沉放驳的水平位移；所述管节升降机构与待安管节连接，用于控制待安管节的竖向位移；所述管节平移机构与待安管节连接，用于控制管节的水平位移。其中，所述沉放驳包括两个独立的船体，所述两个船体分别位于所述待安管节的两端。本实用新型结构简单，采用沉放驳、管节升降机构、管节平移机构和沉放驳平移机构实现管节的吊运沉放，控制管节浮运至管节安装段后的姿态，可顺利实现管节的下沉和初步的对接。
摘要（英）：

The utility model relates to an immersed tube tunnel construction technology, in particular to a pipe joint hoisting and immersing system. The pipe joint hoisting and immersing system comprises an immersing connector, wherein a pipe joint to be installed is suspended below the immersing connector; pipe joint lifting mechanisms, pipe joint translation mechanisms and immersing connector translation mechanisms are arranged on the immersing connector respectively; the immersing connector translation mechanisms are used for controlling the horizontal displacement of the immersing connector; the pipe joint lifting mechanisms are connected with the pipe joint to be installed and are used for controlling the vertical displacement of the pipe joint to be installed; the pipe joint translation mechanisms are connected with the pipe joint to be installed and are used for controlling the horizontal displacement of the pipe joint; and the immersing connector comprises two independent hulls which are positioned at two ends of the pipe joint to be installed respectively. The pipe joint hoisting and immersing system is simple in structure; the pipe joint can be hoisted and immersed by the immersing connector, the pipe joint lifting mechanisms, the pipe joint translation mechanisms and the immersing connector translation mechanisms; the gesture of the pipe joint floating to the installation section of the pipe joint is controlled; and the sinking and preliminary butt joint of the pipe joint can be smoothly realized.
