吹填陆域锚桩施工技术

Anchor sheet pile construction technology at hydraulic reclamation area

以色列阿什杜德港出运码头采用钢板桩结构。锚桩施工区域为吹填陆域,现场受吹填交叉作业影响,施工设备存在较大安全隐患;受锚桩两侧土压力不均及砂体液化影响,复沉过程中发生偏位现象。通过有效控制吹填管头、围坝囤沙、适当增大填砂范围及预留锚桩偏位等技术措施,有效解决了相关安全问题及技术难题,保证了锚桩施工进度。

The steel sheet pile structure was adopted in Israel Ashdod port staging harbor. Since the anchorsheet pile construction was at the hydraulic reclamation area, the construction facilities faced a safety risk due to theununiform soil pressure on both sides of the sheet pile and sand liquefaction, deviation occurred during restrickingconstruction.Taking measures including controling the head of reclamation pipe, storing sand with temporary dam,and increasing reclamation area and reserving sheet pile deviation, etc., we solved related problems concerningsafety and technology, and ensured the construction schedule of the anchor sheet pile.
