鉴于其较高的单桩承载力、较快的施工进度、较强的穿越土层能力、较低的承载力单价比和较高的性价比,预应力混凝土管桩在地基处理中得到了较为广泛的应用,得到了专家和学者的一致认可。通过预应力混凝土管桩原理及相关特点的介绍以及与灌注桩的对比,体现了预应力混凝土管桩在地基处理中的优越性,然后介绍了管桩在地基处理过程中的施工工艺,并详细介绍了有关质量控制方法,为今后类似工程提供可资借鉴的技术和经验。
In view of its higher bearing capacity of single pile, faster construction progress, stronger ability to pass through the soil layer, lower bearing capacity unit price ratio and higher cost performance, prestressed concrete pipe pile has been widely used in foundation treatment The application has been unanimously approved by experts and scholars. Based on the introduction of prestressed concrete pipe pile principle and related characteristics and the comparison with bored pile, it shows the superiority of prestressed concrete pipe pile in foundation treatment, and then introduces the construction technology of pipe pile in foundation treatment, and details Introduced the relevant quality control methods and provided comparable technologies and experiences for similar projects in the future.
