    摘要:

    孟加拉国某新建燃煤电厂项目所处场地属于海相沉积地层,桩基工程采用钻孔灌注桩。为了解决孟加拉国新的施工工况带来的新的施工问题,按照中国的工程建设标准进行施工,并采用旋挖钻孔灌注桩后压浆施工技术,很好地解决了钻孔沉渣和桩侧泥皮对基桩承载力的影响,提高了基桩承载力,试验检测结果表明,达到了Ⅰ类桩的标准。通过后压浆技术在本项目的成功应用,总结出现场操作控制措施,为“一带一路”国家钻孔灌注桩后压浆施工技术提供借鉴经验。

    Abstract:

    The new coal-fired power plant project in Bangladesh is located in marine sedimentary strata, and bored piles are used for the pile foundation. In order to solve the construction problems brought about by the new construction conditions in Bangladesh, the construction was carried out according to the construction standards of China, and rotary drilling bored piles with post grouting were adopted to eliminate the influence of drilling settlements and mud cake around the piles on the bearing capacity of foundation piles; thus improving the bearing capacity of foundation piles. The test results showed that the piles met the Class I standard. Through the successful application of post grouting technology in this project, the field operation control measures are summarized, which can provide reference for bored pile post grouting construction technology in “the Belt and Road” countries.
