夯扩桩是沉管灌注桩实行扩底的一种新桩型,通过对桩端混凝土的夯压,使桩底形成扩大头,大幅度提高桩的承载力,降低工程造价,本文结合广东惠州长期苑居住小区工程实践,对夯扩桩设计、施工质量控制、静载检测及经济比较进行了分析和总结,对该桩型在一般软土地基上多层住层的应用提出了建议。 The rammed-enlarged pile is a new pile type with immersed pipe cast-in-place pile to expand the bottom. Through the pressure on the concrete at the pile end, the pile head is enlarged and the bearing capacity of the pile is greatly improved, and the construction cost is reduced. This paper combines Huizhou, Guangdong Province. In the long-term residential community project practice, the design, construction quality control, static load detection and economic comparison of the rammed-expanded piles were analyzed and summarized, and suggestions were made for the application of multi-story residence layers on the general soft soil foundation.
