钻孔灌注桩是桩基工程中的一个重要的桩型,在土木工程行业中使用非常广泛。在复杂地层和环境条件下进行钻孔灌注桩的施工,桩基质量往往不能得到有效保证。通过在钻成孔过程中全程采用钢套管护壁,为在复杂地层环境中进行灌注桩施工提供了一个高效、节能、绿色的施工技术。在介绍全套管钻孔桩成套技术构成及设备的基础上,详细介绍了应对各种复杂地层环境的施工措施和应对策略。
Bored piles are an important type of piles in pile foundation engineering and are widely used in civil engineering. In complex formation and environmental conditions for the construction of bored piles, pile quality often can not be effectively guaranteed. Through the use of steel casing protection wall throughout the process of drilling and forming, it provides an efficient, energy-saving and green construction technology for pouring pile construction in complex formation environment. Based on the introduction of the complete technical composition and equipment of the complete pipe bored pile, the construction measures and coping strategies for various complicated formation environments are introduced in detail.
