摘要
介绍钻孔喷灌微型桩的施工工艺技术，阐述通过压浆增加强度的重要成桩机理，提供确定承载力的方法。以工程实例为据，说明该桩型的实用效果。
The construction technology of grout injected mini piles by injection grouting is introduced. The mechanism of increasing the strength of the pile through grouting is elaborated and the way to determine the bearing capacity of the pile is presented. According to the practical project, the functional effects are verified.
