岩溶地区码头嵌岩灌注桩的施工方案与技术经济比较

Technical and Economic Comparison of Construction Plan for Rock-embedding Driven Cast-in-place Pile in Karst Region

结合长江中游某高桩码头扩建工程的嵌岩灌注桩施工案例,重点介绍在岩溶地区的嵌岩灌注桩成桩施工中应注意的主要问题,结合当地的自然和施工条件,通过技术经济比较确定合理的嵌岩灌注桩施工方案,采取必要的工程技术措施以保证施工质量、缩短工期和节省工程投资。

Based on the construction of rock-embedding driven cast-in-place pile m plied wharf extension project in the middle reaches of the Yangtze River, the problems that affect the construction of rock-embedding pile in karst region are introduced as key points. By referring to local natural and construction conditions, reasonable construction plan is determined through technical and economic comparison. Meanwhile, necessary technical measures are adopted to guarantee construction quality, shorten construction period and lower project investment.
