Summary:A foundation slab pile repairing construction method utilizing self-locking anchor rods comprises the following steps that firstly, a foundation concrete slab (3) on the periphery of a bearing platform (2) is chiseled, holes are drilled in a soil body below the foundation slab (3), and newly-added piles (5) are implanted into soil; and secondly, oblique anchor rods (6) are implanted in the foundation slab (3), and the oblique anchor rods (6) penetrate through the newly-added piles (5) to be anchored in the bearing platform (2). And thirdly, damaged steel bars in the foundation slab (3) are welded and repaired, and the foundation slab (3) is filled and recovered through concrete. According to the pile repairing scheme, an original bearing platform does not need to be expanded, and compared with a pile repairing scheme with an expanded bearing platform, the construction amount is small, construction is convenient, cost is saved, and the construction period is shortened. 一种利用自锁锚杆的基础底板补桩施工工法，包括以下步骤：步骤一，凿开承台(2)周边的
