Construction technology for converting large-diameter single pile foundation into pile barrel combined foundation
The invention discloses a construction technology for converting a large-diameter single pile foundation into a pile barrel combined foundation, which comprises the following steps of: S1, cutting an original large-diameter single pile, and grinding a tangent plane; s2, a barrel-shaped foundation is prepared according to the size of the remaining section of the remaining original single pile foundation; s3, foreign matter checking and leveling are conducted on the surrounding area of the remaining section of the original single-pile foundation; s4, the barrel-shaped foundation is arranged on the remaining section of the original single-pile foundation in a sleeving mode; s5, negative pressure injection of the barrel-shaped foundation is carried out; s6, cement mortar pouring is conducted on the barrel-shaped foundation, and fine aggregate concrete filling is conducted between the remaining section of the original single-pile foundation and the barrel-shaped foundation; s7, machining and manufacturing of the implantable inner pile are conducted; and S8, the implantable inner pile is implanted into the remaining section of the original single pile foundation, and concrete grouting is conducted between the remaining section of the original single pile and the implantable inner pile. The construction risk and difficulty are effectively reduced, the mechanical equipment cost is reduced, and the economical efficiency and safety of the construction process are greatly improved.
本发明公开一种大直径单桩基础转换桩桶组合基础施工技术，包括如下步骤：S1，对原有大直径单桩进行割桩处理，并对切面进行磨平处理；S2，根据剩余原单桩基础剩余段尺寸制备桶形基础；S3，对原单桩基础剩余段周围区域进行异物排查并整平；S4，将桶形基础套设在原单桩基础剩余段上；S5，进行桶形基础负压贯入；S6，对桶形基础进行水泥砂浆灌注，在原单桩基础剩余段与桶形基础之间进行细石混凝土填充；S7，进行植入式内桩的加工制作；S8，将植入式内桩植入至原单桩基础剩余段，在原单桩剩余段与植入式内桩之间进行混凝土注浆。本发明有效降低施工风险和难度，减少机械设备成本，极大提升施工过程的经济性和安全性。
