高桩梁板码头排水方式探讨

对于普通货种的高桩梁板码头,通常在码头纵梁顶部设置盖板明沟进行雨水收集和排放。采用该排水方式时需要在梁板顶部开凿排水沟,而在老码头的排水系统改造工程中,该方式会破坏现有码头结构,增加工程投资。以江苏省某老码头排水改造工程为例,提出一种暗管排水方式,并对关键节点进行标准化设计。结果表明,暗管排水方式投资较低、对码头结构影响较小,可为类似工程提供借鉴。

Discussion on drainage method of high piling beam-slab quay

For high piling beam-slab quay with common cargo,cover plate and gutter are normally set up on top of longitudinal beam as the rain collection and drainage facilities.For the rehabilitation of old quay,this drainage method needs to cut gutter on top of the beam,which will damage the existing quay structure and increase the investment.Taking the drainage renovation project of an old quay in Jiangsu province as an example,we propose an underground pipe drainage method,and carry out standardized design of key nodes.The results show that the underground pipe drainage method has low investment and little influence on quay structure.It can provide references for similar projects.
