摘要
针对场地受限条件下的高桩码头加固改造工程,围绕码头结构拆除和新增桩基施工会对邻近保留结构产生不利影响的关键问题,结合镇江港、泰州港等码头加固改造工程实际案例,总结分析相关施工工艺的优缺点,明确适合于有限施工空间的码头结构拆除原则与方法,提出柴油锤与振动锤联合沉桩的新增桩基陆上施工工艺,对类似高桩码头的加固改造工程具有一定的参考借鉴价值。
According to the reinforcement and reconstruction of high pile wharf under re- stricted site, the key problems about the demolition of wharf and new pile foundation con- struction which have adverse effects on adjacent retention structure are discussed. The advan- tages and disadvantages of related construction technology are summarized combined with the case of the wharf reinforcement and reconstruction project in Zhenjiang and Taizhou ports, The principle and method of demolition of wharf structures suitable for limited construction space are defined. The land construction technology of new pile foundation combined with diesel and vibratory hammers is put forward, which provides a reference for the similar project of high pile wharf.
