浅谈夯扩桩工程质量监理

Study on the Quality Supervision of Ramming-expanded Pile Project

夯扩桩是一种常用桩型,适用于一般粘性土、粉土、砂土等土层,具有较好的经济技术指标,它比其他混凝土灌注桩降低基础造价30%～40%,但在其施工时,影响成桩质量的因素较多。文章从监理的角度谈谈从设计到施工全过程中夯扩桩的质量控制方面应注意的问题。

The ramming-expanded pile is a kind of new pile, which is suitable to common cohesive soil, silt soil or sand soil foundation, and with better economical and technical norms, it could reduce the foundation construction cost by 30% to 40% compared with the other concrete cast-in-placo piles, but there are many factors that may influence the construction quality. From the perspective of supervision, this article discusses the problems that should be paid attention to in the quality control of the ramming-expanded pile from design to construction.
