| 中文摘要:阜阳华纺新天地桩基工程，原计划基坑底面施工调整为地面施工，增加了近14 m的空桩。为此，工程桩施工质量存在桩位、孔底沉渣厚度、钢筋笼位置、砼质量、砼桩顶标高等方面控制的相关问题。本文介绍了其施工情况，其经验可供类似工程借鉴。 |

| Abstract:In a pile foundation project in Fuyang, the originally planned construction at the foundation pit bottom is changed to be on the ground, and nearly 14m hollow piles should be added in adition. Therefore, some related problems affecting the construction quality of engineering pile are produced, such as pile location, slag thickness at hole bottom, position of reinforcement cage, concrete quality, elevation of concrete pile top and so on. This paper introduces the construction situation, and the experience can be used as reference for similar projects. |
