Embankment type steel flower pipe pile foundation joist anchor pipe anchor cable high retaining wall structure and construction method
The invention discloses an embankment type steel flower pipe pile foundation joist anchor pipe anchor cable high retaining wall structure. The embankment type steel flower pipe pile foundation joist anchor pipe anchor cable high retaining wall structure comprises a vertical reinforced miniature steel flower pipe pile foundation, a reinforced concrete joist and an oblique prestressed steel anchor pipe anchor cable, wherein the oblique prestressed steel anchor pipe anchor cable comprises a steel anchor pipe and a prestressed steel strand bundle arranged in the steel anchor pipe, a steel anchor pipe drill hole is obliquely and downwards formed in the slope surface of a side slope in the mode of penetrating through a cast-in-place reinforced concrete pile plate retaining wall, the steel anchor pipe and a prestress steel strand bundle extend into the steel anchor pipe drill hole, a plurality of secondary grouting holes are spirally formed in the steel anchor pipe, cement grouting bodies are arranged in the steel anchor pipe and the steel anchor pipe drill hole, and a tensioning table for locking the steel anchor pipe and the prestressed steel strand bundle is arranged at the pipe orifice position of the steel anchor pipe. According to the embankment type steel flower pipe pile foundation joist anchor pipe anchor cable high retaining wall structure and the construction method, the technical problems that a traditional pile foundation joist retaining wall technology is high in construction condition requirement, low in manual hole digging speed and high in comprehensive manufacturing cost are solved, and the pile foundation joist retaining wall structure is widely applied to slope reinforcement engineering of highways, railways and the like.
本发明公开了一种路堤式钢花管桩桩基托梁锚管锚索高挡墙结构，包括竖向加筋微型钢花管桩基、钢筋混凝土托梁和斜向预应力钢锚管锚索，斜向预应力钢锚管锚索包括钢锚管和设置于钢锚管内的预应力钢绞线束，贯穿现浇式钢筋混凝土桩板挡墙向边坡坡面倾斜向下设有钢锚管钻孔，钢锚管和预应力钢绞线束伸入钢锚管钻孔内，钢锚管上螺旋设有若干二次注浆孔，钢锚管和钢锚管钻孔内设有水泥注浆体，钢锚管的管口位置设有用于锁紧钢锚管和预应力钢绞线束的张拉台。本发明解决了传统桩基托梁挡墙技术存在的施工条件要求高，人工挖孔速度慢，综合造价高的技术问题，其广泛用于公路、铁路等的边坡加固工程中。
