SMW construction method pile applied to subway deep foundation pit engineering
The invention discloses an SMW construction method pile applied to subway deep foundation pit engineering. The SMW construction method pile comprises a foundation, foundation pits, three-axis stirrers, slurry pipes, slurry filling areas, casing drills, foundation pit planes, H-shaped channel steel and lifting holes. The SMW construction method pile has the beneficial effects that the SMW construction method pile is applied to foundation pit enclosure construction, good economic and social benefits are obtained, compared with an underground diaphragm wall, the cost is saved by about 30%, the anti-permeability performance is good, the permeability coefficient reaches 9-6 cm/s, the pile body rigidity is similar to that of a cast-in-place pile, spoil is little, and pollution to the surroundingenvironment is small; and the SMW construction method pile has the characteristics of small disturbance during construction, no mud pollution, small vibration noise, good water stop performance, short construction period, less waste soil outward transportation, low construction cost and the like.
本发明公开了一种在地铁深基坑工程中应用的SMW工法桩，包括地基、基坑、三轴搅拌机、泥浆管、泥浆填充区、套钻、基坑平面、H型槽钢和吊孔。本发明的有益效果是：SMW工法桩在基坑围护施工中的应用，获得良好的经济和社会效益，它与地连墙相比，节约成本约30％，它抗渗性能较好，渗透系数达9‑6cm/s，桩体刚度与灌注桩相似，弃土少，对周边环境污染小，而且SMW工法桩具有施工时扰动小、无泥浆污染、振动噪声小、止水性能好、施工工期短、废土外运少、工程造价低等特点。
