Hectometer-level deepwater immersed tube large-tolerance butt joint device and butt joint method
The invention provides a hectometer-level deepwater immersed tube large-tolerance butt joint device and a butt joint method, and belongs to the technical field of immersed tube tunnel installation. A butt joint assembly is matched with a water surface and underwater dual-power sinking device, a sinking barge is used for controlling a suspension steel wire rope and a detachable sinking pipe clamp to control up-down displacement of a deep water sinking pipe underwater, and a first hydraulic propeller and a second hydraulic propeller are used for controlling front-back and left-right displacement of the deep water sinking pipe; through a large-tolerance guide structure composed of the conical sleeve and the cone frustum, rapid and reliable butt joint of the hundred-meter deep water immersed tube tunnel is achieved. Technical guidance can be provided for installation of hectometer deep water immersed tube joints, the initial positioning allowable deviation is reduced to the centimeter level, the engineering cost can be greatly saved, the safety risk is reduced, and technical guarantee is provided for practical engineering application. The problem of low docking and positioning accuracy caused by large tolerance deviation in the underwater docking process of deep water immersed tubes in the prior art can be solved.
本发明提供了一种百米级深水沉管大容差对接装置与对接方法，属于沉管隧道安装技术领域。由对接组件与水面水下双动力沉放装置配合，利用沉放驳控制悬吊钢丝绳和可拆卸沉管夹控制深水沉管在水下的上下移位，利用第一液压推进器和第二液压推进器控制深水沉管的前后左右移位，通过锥形套管和圆锥台组成的大容差导向结构，实现百米深水沉管隧道的快速、可靠对接。可为百米深水沉管管节安装提供技术指导，初始定位容许偏差降至厘米级，可大幅节省工程成本，降低安全风险，为实际工程应用提供技术保障。能够解决相关技术中深水沉管在水下对接过程中容差偏差较大导致对接和定位精确度低的问题。
