河道堤防搅拌桩截渗墙试验布置成15m×6m的封闭长方形，由搅拌桩连接而成，直径500mm，搭接200mm，深约6m，桩体喷灰比是18％，桩体待凝28d后，进行抽水试验并钻取墙体岩芯，送室内作渗透性测定和力学强度试验，墙体综合渗透系数为A×10~(-6)cm／s．室内样品渗透系数为A×10~(-6)cm／s，试验结果表明搅拌桩截渗墙用于该工程是可行的，由此可以大大降低工程造价，提高工效，保证工期．
The river embankment mixing pile cutoff wall test layout arranged 15m × 6m closed rectangle, connected by a mixing pile, diameter 500mm, lap 200mm, depth of about 6m, the ratio of 18% , Pumping tests were carried out and the core of the wall was drilled. The permeability and the mechanical strength of the wall were measured and the permeability coefficient of the wall was A × 10 ~ (-6) cm / s. The indoor permeability coefficient is A × 10 ~ (-6) cm / s. The experimental results show that it is feasible to use the mixing pile cutoff wall for the project, which can greatly reduce the project cost, enhance the work efficiency and ensure the construction period.
