Inclined wedge-shaped pile and vertical wedge-shaped pile combined supporting structure and construction method thereof
The invention discloses an inclined wedge-shaped pile and vertical wedge-shaped pile combined supporting structure. The structure comprises wedge-shaped piles A inclined to the horizontal plane and wedge-shaped piles B perpendicular to the horizontal plane. The wedge-shaped piles A and the wedge-shaped piles B are alternately arranged to form the piling supporting structure. The wedge-shaped pilesA and the wedge-shaped piles B are arranged at the inner side of the edge of a foundation pit. A crown beam is arranged on the pile tops of the wedge-shaped piles A and the wedge-shaped piles B. Thelower portions of the wedge-shaped piles A are inclined towards the interior of the foundation pit. The areas of the cross sections of the wedge-shaped piles A and the wedge-shaped piles B become smaller successively from the pile top to the pile bottom. The line of centers of the pile tops of the wedge-shaped piles A are parallel to or coincide with the line of centers of the pile tops of the wedge-shaped piles B. The invention further discloses a construction method of the inclined wedge-shaped pile and vertical wedge-shaped pile combined supporting structure. Pile top displacement can be reduced, the cutting depth can be increased, the foundation pit overturn damage probability is lowered, the supporting pile design strength can be reduced so as to lower the manufacturing cost.
本发明公开了一种倾斜楔形桩与竖直楔形桩的组合支护结构，包括倾斜于水平面布设的楔形桩A和垂直于水平面布设的楔形桩B，所述楔形桩A和所述楔形桩B交替排列构成排桩支护结构；所述楔形桩A和所述楔形桩B沿基坑边沿内侧设置，在所述楔形桩A和所述楔形桩B的桩顶上设有冠梁；所述楔形桩A的下部向基坑内倾斜，所述楔形桩A和所述楔形桩B的横截面的面积从桩顶至桩底依次变小；所述楔形桩A的桩顶中心连线与所述楔形桩B的桩顶中心连线平行或重合。本发明还公开了一种倾斜楔形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。
