Old pile lower pile splicing structure and construction method thereof
The invention relates to an old pile lower pile splicing structure. The old pile lower pile splicing structure comprises a bearing platform and old piles, wherein the old piles are arranged under the bearing platform, lower pile holes are formed in the bottoms of the old piles, the cross section of each lower pile hole is in a circular shape, a symmetrical fan shape or an oval shape, and the cross section contour of each lower pile hole is larger than the minimum envelope contour of the outer edge of the corresponding old pile; lower piles are arranged in the lower pile holes, the lower piles correspond to 2-4 old piles under the same bearing platform, and the lower piles are overlapped with the old piles; and upper pile holes are formed in one sides of the old piles in parallel, the cross section contour of each upper pile hole is smaller than the cross section contour of the corresponding lower pile hole, upper piles are arranged in the upper pile holes, the upper piles are overlapped with the lower piles, and the bearing platform, the lower piles, the upper piles and the old piles are poured into a whole. The invention further relates to an old pile lower pile splicing construction method. According to the old pile lower pile splicing structure and the construction method thereof, the upper piles are implanted beside the old piles, the lower piles are implanted below the old piles, so that the upper piles, the lower piles and the old piles are poured into a whole, the cooperative bearing capacity of a new structure and an old structure can be improved, and the old pile lower pile splicing structure and the construction method thereof can well serve the construction of old city reconstruction and building reconstruction and expansion.
本发明涉及一种旧桩下接桩结构，包括承台和旧桩，所述承台下布设所述旧桩，旧桩桩底开设有下桩孔，所述下桩孔截面为圆形、对称扇形或椭圆形的一种，下桩孔截面轮廓大于旧桩外缘最小包络轮廓；所述下桩孔内布设有下桩，所述下桩与同一承台下的2~4根旧桩相对应，下桩与所述旧桩之间存在重叠；所述旧桩一侧平行开设有上桩孔，所述上桩孔截面轮廓小于下桩孔截面轮廓，上桩孔内布设有上桩，上桩与所述下桩之间存在重叠，所述承台、下桩、上桩和旧桩浇筑为一体。本发明还涉及一种旧桩下接桩施工方法。本发明通过在旧桩旁植入上桩、旧桩下方植入下桩，使三者浇筑为一体、可增加新旧结构的协同承载能力，可良好服务于旧城改造和建筑物改扩建的施工。
