摘要
在高低跨结构桩基施工过程中,桩身临边或桩基位于基坑放坡面上时,低跨结构施工完成再进行挡墙回填后往往会在工期和成本方面造成较大影响,性价比较低。采用在高跨地面上先通过切坡扩孔,随后进行人工挖孔并接桩的方式,较好地解决工期及成本问题。
In the process of pile foundation construction of high-and-low span structure,when the pile is near the side or the pile is located on the slope of foundation excavation,the construction method after the completion of low span structure construction and the backfilling of retaining wall often has a great impact on the construction period and cost,with low cost performance.In order to solve the problem of construction period and cost,the method of cutting slope and expanding hole first and then digging hole and connecting pile manually is adopted.
