Design of Drilling Path and Structural Protection for Micro-pile Implantation Machinery for Ancient Building Reinforcement
Taking the ancient building complex of Zhangguying Village in Yueyang County, Hunan Province as the research object, this paper elaborates the optimization of micro-pile drilling paths, adaptive improvement of light drilling rigs, structural protection design, and construction coordination. Construction schemes including angled drilling layout, modular design, and vibration suppression of micro-drilling rigs, foundation underpinning, external wall support, and waterproofing & anti-seepage are proposed to improve the bearing capacity of ancient building foundations and control settlement. The research conclusions show that settlement can be controlled within 5%–8%, vibration amplitude ≤0.5 mm, and crack expansion ≤1 mm during reinforcement. The results prove that the proposed scheme can realize efficient and safe micro-pile reinforcement in narrow courtyards and dense wall environments while guaranteeing construction efficiency and structural stability, and effectively reducing disturbance to ancient building foundations.
