Combined supporting structure adopting inclined pipe piles and vertical bamboo joint piles and construction method of combined supporting structure
The invention discloses a combined supporting structure adopting inclined pipe piles and vertical bamboo joint piles. The combined supporting structure comprises a row pile supporting structure formedby alternately arranging the pipe piles and the bamboo joint piles; the pipe piles and the bamboo joint piles are arranged along the inner side of the edge of a foundation pit, and top beams are arranged on the pile tops of the pipe piles and the bamboo joint piles; the axes of the bamboo joint piles are perpendicular to the horizontal plane, a plurality of annular protrusions perpendicular to the axes of the bamboo joint piles are arranged on the outer surfaces of pile bodies, and annular reinforcing ribs are arranged in the annular protrusions; the axes of the pipe piles incline to the horizontal plane, and the lower portions of the pipe piles incline into the foundation pit; and a pile top center connecting line of the pipe piles is parallel to or coincides with a pile top center connecting line of the bamboo joint piles. The invention further discloses a construction method of the combined supporting structure adopting the inclined pipe piles and vertical bamboo joint piles. The displacement of the pile tops can be reduced, the excavation depth is increased, the overturning damage possibility of the foundation pit is reduced, and the design strength of the supporting piles canbe reduced so as to reduce the manufacturing cost.
本发明公开了一种倾斜管桩与竖直竹节桩的组合支护结构，包括由管桩和竹节桩交替排列构成的排桩支护结构；所述管桩和所述竹节桩沿基坑边沿内侧设置，在所述管桩和所述竹节桩的桩顶上设有冠梁；所述竹节桩，其轴线垂直于水平面，其桩身外表面设有若干垂直于其轴线的环形凸起，环形凸起内设有环形加强筋；所述管桩的轴线倾斜于水平面且其下部向基坑内倾斜；所述管桩的桩顶中心连线与所述竹节桩的桩顶中心连线平行或重合。本发明还公开了一种倾斜管桩与竖直楔形桩的组合支护结构的构造方法。本发明可减小桩顶位移，增加开挖深度，降低基坑倾覆破坏可能性，可减小支护桩设计强度以降低造价。
