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.Ancient building protection, Micro-pile reinforcement, Drilling path optimization, Structural protection
