强浪条件下高桩码头桩间大棱体抛石及块体安装施工技术

针对在建的以色列阿什杜德港项目28号码头桩间抛石及块体安装施工工期紧张且窗口期有限、工程量大且作业面有限,以及抛填安装棱体大且验收标准高的难点,采用将组合钢板架设在夹桩结构上作为施工平台并由履带吊搭配特定抛填安装工具的施工方案。介绍现场实施进度情况及越冬防护结构的设计,为类似海况条件下的高桩码头桩间抛石及块体安装施工提供借鉴。

Construction technique of massive rock dumping and armor block installation between piles of high-pile wharf under strong wave condition

To solve the difficulties of limited schedule,work window and operation area,together with massive size and large quantity of rock and armor block,and high inspection acceptance requirement of the rock dumping and armor block installation construction between piles of Hadarom port at Ashdod,Israel,we put forward the solution which use separable composited steel plates onto the top of the temporary support of steel pipe piles as a working platform for crawler crane working with typical equipment for different types of rocks and armor block with the construction progress record and winter protection design,to serve as reference for the rock dumping and armor block installation construction between piles of standing pile wharf under similar wave condition.
