大直径超长桩与普通桩相比并无本质区别,但由于桩径大、桩孔深,其施工难度要比普通桩大得多,所采用的机具设备、施工方法和施工工艺也不尽相同。本文针对大直径超长桩的特殊需求,提炼出了一些与普通桩不同的施工要点和注意事项以及质量控制措施,希望为相关施工人员提供一点参考。 There is no essential difference between large-diameter super-long piles and ordinary piles. However, due to large pile diameter and deep piles, the construction difficulty is much larger than that of ordinary piles. The equipment, construction methods and construction techniques used are also not enough the same. In this paper, according to the special requirements of large-diameter extra-long pile, some construction points, precautions and quality control measures which are different from ordinary pile are extracted, and hope to provide some reference for relevant construction workers.
