摘要
近年來台灣地區之場鑄基樁施工技術因經驗之累積已日趨成熟,大口徑及超長基樁已普遍運用於各項工程,專家學者對相關之施工方法及品質管理也多有論述發表,然而在實踐過程中隨著對基樁行為進一步的瞭解,發現目前之施工方式仍有討論及改善之空間。因此本文首先整理歸納國內常用之基樁施工工法之特性及適用範圍,然後針對施工過程中影響成樁品質之重要步驟,如孔壁穩定方式、垂直度與孔徑之控制及檢測、樁底沈泥處理、鋼柱吊放以及樁底後灌漿等工作項目,說明與檢討現行常用各種施工方式之特點及優劣,並提出對施工方式及品質管理之建議與注意事項,供規劃及施工人員參考。
英文摘要
As the designers and contractors are gaining a great deal of experience from pile construction projects, large diameter and super long bored pile have commonly been used in Taiwan. In the past decades, many papers have discussed the issues of pile construction and quality control. This paper describes the pile construction method and addresses the factors that affect the construction quality of piles. These factors may include method to stabilize a bored hole, vertical alignment of drilling, diameter control and check, bottom cleaning, placing steel sections and post grouting of pile bottom. Finally, recommendations on pile construction quality control are given for reference.
