为了分析接杆粉喷桩施工工艺与施工参数对成桩质量的影响,选取连宿高速公路典型软土场地,采用现场试桩方法,选取不同施工参数和施工工艺的接杆搅拌桩进行地基处理,成桩后进行标准贯入试验、取芯率试验和28 d无侧限抗压强度试验来评价成桩质量,以此确定最佳施工工艺和施工参数。试验结果表明,采用自上而下施工工艺,叶片转速60 r/min,钻杆下钻和提升速度1.0 m/min,水泥掺量80 kg/m是一套适用于连云港海相淤泥质土的施工参数。在实际工程中,应结合工程地质条件与水泥土每遍搅拌次数的公式将各施工参数进行组合与匹配,并选取合适的施工工艺,使得加固范围内任一点的土体搅拌次数达到25次来达到较好的成桩质量和地基处理效果。常规水泥土搅拌桩由于少了接拆杆等复杂的工序,所以成桩质量比接杆搅拌桩更好,但是接杆搅拌桩的成桩质量也能符合规范要求。因此在一些净空受限的施工条件下,采用接杆搅拌桩能够代替常规搅拌桩进行地基处理,强度符合规范要求,同样起到很好的工程应用效果。
To investigate the influence of construction technology and parameters of rod-extended deep mixing piles on the pile formation quality
a typical soft soil site along the Liansu Expressway was selected for field trial piling. Ground improvement was conducted using rod-extended deep mixing piles with varying construction parameters and methods. Following pile formation
standard penetration tests (SPT)
core recovery tests
and 28-day unconfined compressive strength (UCS) tests were conducted to evaluate pile quality and identify the optimal construction method and parameters. The test results showed that a top-down construction method
with a blade rotation speed of 60r/min
drilling and lifting speed of 1.0m/min
and a cement content of 80kg/m
was well-suited for marine silty soil in Lianyungang. In practical engineering applications
construction parameters should be combined and matched based on site-specific geological conditions and the empirical formula for the number of mixing passes per soil layer. Ensuring that the soil at any point within the reinforcement zone is mixed at least 25 times contributes to achieving better pile formation quality and ground improvement effects. Although conventional deep mixing piles typically demonstrate higher pile quality due to the absence of complex processes such as rod coupling and decoupling
rod-extended deep mixing piles still meet the required technical specifications. Therefore
under construction conditions with height limitations
rod-extended deep mixing piles can serve as effective substitutes to conventional piles
meeting strength requirements and achieving satisfactory engineering performance.
