Combined support structure for inclined tubular piles and vertical wedge-shaped piles as well as construction method thereof
The invention discloses a combined support structure for inclined tubular piles and vertical wedge-shaped piles. The combined support structure comprises a row pile support structure which is formed by alternatively arranging tubular piles and wedge-shaped piles, wherein the tubular piles and the wedge-shaped piles are arranged inside an edge of a foundation pit; a crown beam is arranged on the pile tops of the tubular piles and the wedge-shaped piles; axes of the wedge-shaped piles are perpendicular to the horizontal plane, and areas of cross sections of the wedge-shaped piles are sequentially reduced from pile tops to pile bottoms; axes of the tubular piles are inclined relative to the horizontal planes, and the lower parts of the tubular piles are inclined towards the inner part of thefoundation pit; and the center connecting line of the pile tops of the tubular piles is parallel to or superposed with that of the pile tops of the wedge-shaped piles. The invention further disclosesa construction method for the combined support structure for the inclined tubular piles and the vertical wedge-shaped piles. The combined support structure can reduce pile top displacement, increasesexcavation depth, reduces foundation pit toppling failure possibility, and reduces design strength of the support piles to reduce the manufacturing cost.
本发明公开了一种倾斜管桩与竖直楔形桩的组合支护结构，包括由管桩和楔形桩交替排列构成的排桩支护结构；所述管桩和所述楔形桩沿基坑边沿内侧设置，在所述管桩和所述楔形桩的桩顶上设有冠梁；所述楔形桩，其轴线垂直于水平面，其横截面的面积从桩顶至桩底依次变小；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楔形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。
