Improved expansive soil high-steep slope structure
The invention discloses an improved expansive soil high-steep slope structure. The structure is characterized in that top vegetation grooves and side wall vegetation grooves are respectively arrangedon a slope top and an inclined wall of a high-steep slope, groove bodies of the vegetation grooves are anchored on the high-steep slope through a plurality of soil nails, openings are formed in the groove bodies, grouting holes are drilled in the high-steep slope through the openings, slurry is injected into the grouting holes, loess is filled in the vegetation grooves, and vine type green plantsare cultivated. According to the structure, the grouting holes are filled with grout formed by mixing collapsible loess and coarse silt, finally seepage columns extending into expansive soil are formed after solidification, the loess slowly permeates into the expansive soil along with rainwater to improve the expansive soil, cracks caused by expansion are filled, the coarse silt serves as frameworks of the seepage columns to form seepage channels for the loess to scour and flow, the loess in the vegetation grooves can continuously permeate into the expansive soil along the seepage channels after being scoured along with the rainwater, the cracks generated by expansion and contraction of the expansive soil are compensated, and the overall mechanical property of the slope is improved.
一种改良膨胀土高陡边坡结构，在高陡边坡的坡顶和斜壁上分别设置有顶部植生槽和侧壁植生槽，植生槽的槽体通过若干土钉锚固在高陡边坡上，在槽体内开设有开口，并且穿过该开口在高陡边坡内钻注浆孔，再向注浆孔内注入浆体，在植生槽内填充黄土并栽培藤蔓型绿植。本发明在注浆孔内灌注由湿陷性黄土和粗泥沙混合而成的浆液，最终在凝固后形成伸入膨胀土内的渗流柱，黄土随雨水缓慢渗透到膨胀土内对其进行改良，填充膨胀造成的裂缝，粗泥沙作为渗流柱的骨架形成供黄土冲刷流动的渗流通道，植生槽内的黄土随雨水冲刷后能够沿渗流通道持续渗入到膨胀土内，以弥补膨胀土涨缩所产生的裂隙，提升了边坡整体的力学性能。
