接桩卡具的设计及受力分析

随着我国海洋石油工业的迅速发展,对海洋平台的桩基础提出了更高的要求,目前海工结构物的钢管桩基础具有桩径大、桩身长的特点,在海上进行接桩施工是海洋平台建造和安装中不可缺少的工序。针对海上接桩施工的特点及其面临的实际问题,结合某实际工程介绍了一种实用的接桩卡具,并对这一卡具的设计方法及受力特点进行了详细的分析。实际应用表明,该卡具的使用效果良好,具有通用性并可反复使用。

Design and Mechanical Analysis of Clamping Apparatus Used for Pipe Connection

Along with the rapid developinent of ocean petroleum industry in China, the demand for platform pile foundation is more essential. At present, steel pile foundation of offshore structure has features of larger diameter and longer length. It is unavoidable task to fulfill pipe connection operation at sea. On the basis of a practical project, this paper describes a workable clamping apparatus suitable for marine operation of pipe connection, its detailed design method and mechanics feature. The application shows that clamping apparatus achieves a good results of common and repeatable usage.
