水平定向钻环空泥浆改良施工技术及评价——以焦作供水博爱线为例
发布时间：2018-11-15 22:46
【摘要】：河南省焦作市供水博爱线在与南水北调中线总干渠交叉处采取水平定向钻穿越的施工方式,为了确保总干渠输水的安全,采取了多项技术保障措施。具体阐述了泥浆置换方案比选、灌浆管预埋施工、置换泥浆配比选择、环空泥浆改良性能评价等方面需注意的问题,并提出了大孔径水平定向钻环空泥浆置换改良施工技术、评价以及优化改进建议。相关经验可供类似工程借鉴。
[Abstract]:The construction method of horizontal directional drill crossing between Boai line of water supply in Jiaozuo City Henan Province and the main canal of South-to-North Water transfer Project is adopted. In order to ensure the safety of water conveyance in the main canal a number of technical guarantee measures have been taken. The problems of mud replacement scheme comparison, grouting pipe pre-burying construction, replacement slurry ratio selection, annulus mud improvement performance evaluation, etc., are expounded in detail. The improved construction technology of large aperture horizontal directional drilling annulus mud replacement is put forward. Evaluate and optimize suggestions for improvement. Relevant experience can be used for reference in similar projects.
