摘要
人工挖孔成桩是一种简单而易行的成孔方式,依据此桩的承载特征对人工挖孔桩设计进行了系统介绍,提出了在人工挖桩体中设置支盘方式来达到提高单桩承载力的一种设计思路,同时介始了桩端扩孔超前支护工艺,以供施工中借鉴。
Manual dug hole piling is a kind of simple and easy hole forming method.A systematic introduction is carried out according to the pile load bearing characteristics.Put forward an idea to set a support disk for raising single pile load bearing capacity, and an advancing supporting technique of pile end enlarged base, use for reference in construction.
