2010年8月 中国港湾建设 Aug.，2010 第4期 总第168期 China Harbour Engineering Total168，No.4 小开底驳船在窄桩间大棱体高桩码头 抛石施工中的应用 周雯，褚凤龙，于德洲 （中交一航局第三工程有限公司，辽宁 大连 116001） 摘 要：大连长兴岛公共港区通用泊位高桩码头为窄桩间大棱体接岸抛石结构，皮带机抛石船和方驳配反铲抛石船 均无法满足工期要求。采用自制的小开底驳船抛石施工工艺，通过合理的分区分层抛填，跟踪测量监控，适时调整 施工参数，确保了因抛石引起的桩位偏差（没采取夹桩工艺）在规范允许的范围内，大大提高了施工效率，有效解 决了抛石施工难题，为类似高桩码头抛石施工提供了经验。 关键词：高桩码头；窄桩间大棱体接岸抛石结构；小开底驳船；施工工艺 中图分类号：U656.113文献标志码：A 文章编号：1003-3688（2010）04-0062-05 Application of Bottom Dump Hopper Barge for Rock Dumping Construction among Piles in Narrow Spacing Filled with Riprap Mound at High Pile Jetty ZHOU Wen ，CHU Feng-long， YU De-zhou （No.3 Engineering Company Ltd. of CCCC First Harbor Engineering Company Ltd. ，Dalian，Liaoning 116001 ，China） Abstract ：The high pile jetty consisting of general berths of Changxing Island Public Port Zone in Dalian is a linking shore structure with riprap mound in quantity among the piles in a narrow pile -to -pile spacing ， a self -manufactured bottom hopper barge shall be adopted since the riprap barges with neither belt conveyor nor backhoe excavator are able to meet the requirements of the whole duration ；Riprap-filling activities shall be executed by reasonable layers and different distributions ； Further their track ， survey ， supervision and control shall be carried out to adjust the construction parameters in due course. All of the above practices ensure the location deviation of piles within permissible tolerance specified in the Specification （caused by no application of pile clampi
