SMW工法桩因施工效率高、适用土层范围广、桩身均匀性好、造价低等优点,被广泛运用于深基坑支护和地基加固领域。SMW工法桩的地下隐蔽性,施工过程中无法直接看到成桩效果;施工中的偏差,容易造成大的质量事故,甚至后期危及基坑安全。本文结合工程实例,详细介绍SMW工法桩的施工工艺及质量控制。
SMW method pile is widely used in deep foundation pit support and foundation reinforcement because of its high construction efficiency, wide range of applicable soil layers, good pile uniformity and low cost. SMW method of underground concealment pile, the construction process can not directly see the pile into effect; construction of the deviation, easy to cause large quality accidents, and even endanger the safety of foundation pit. This article combines engineering examples, detailing the SMW pile construction method and quality control.
