介绍一种新型悬挂式桩架,它主要由架体、上筒体和下筒体组成。上筒体上设有导向凹槽,与架体上的纵向导轨形成滑动副,使上筒体能在架体中上下移动。该悬挂式桩架结构设计合理,使用方便,性能优越,能很好地克服使用直桩锤笼打斜桩所产生的缺陷,提高筒式柴油打桩锤沉桩作业安全性能,可以满足国家特大型海上工程大直径钢管桩的沉桩施工要求。
A new type of hanging pile frame is introduced, which is mainly composed of a frame, an upper cylinder and a lower cylinder. A guiding groove is arranged on the upper cylinder body, and a sliding pair is formed on the longitudinal guide rail on the frame body, so that the upper cylinder body can move up and down in the frame body. The structure of the suspended pile frame is reasonable in design, convenient in use and superior in performance, and can well overcome the defect caused by using the straight pile hammer cage to hang oblique pile and improve the safety performance of the pile diesel pile driving pile sinking operation, Requirements of Offset Pile Construction for Offshore Large Diameter Steel Pipe Piles.
