Pile-in-pile broken pile splicing construction method
The invention relates to a pile-in-pile broken pile splicing construction method. The construction process comprises the steps of performing site leveling, performing measurement setting-out, performing rotary drilling for core pulling, performing ribbed steel pipe manufacturing, performing welding, performing reinforcement cage manufacturing, performing mounting, performing ribbed steel pipe hoisting, performing base concrete treatment, performing steel pipe inner side concrete injection, performing steel pipe outer side cement mortar injection and performing concrete curing. According to themethod, the influence of the surrounding geological environment does not need to be considered, and the existing pile body and a core-pulling hole reserved in the core-pulling detection process are utilized to the maximum extent. Compared with a traditional broken pile splicing method, for the method disclosed by the invention, the implementation process is lower in cost and higher in construction progress.
本发明涉及一种桩中桩断桩接桩施工方法，施工流程：场地平整、测量放样、旋挖钻抽芯、加肋钢管制作、焊接、钢筋笼制作、安装、吊装加肋钢管、基底混凝土处理、钢管内侧注混凝土、钢管外侧注水泥砂浆、混凝土养护。本发明不用考虑周边地质环境的影响，最大化利用了既有桩体及抽芯检测过程留下的抽芯孔，本发明的实施过程较传统断桩接桩方法成本较低且施工进度较快。
