Construction method for improving embankment filler weak expansive soil lime
The invention discloses a construction method for improving embankment filler weak expansive soil lime. The construction method comprises the following steps: 1, testing the proportion of lime-improved weak expansive soil; 2, checking parameters such as longitudinal fracture elevation of a lower bearing layer to meet construction conditions; 3, performing quick lime digestion; 4, transporting the weak expansive soil to a construction site, and after filling of the weak expansive soil is completed, adopting a bulldozer for rough levelling and elevation measurement; 5, performing ash spreading by using a traction type full-automatic ash spreading truck, and controlling the spreading quantity of the lime by using a numerical control high-precision flow regulating valve; 6, actually measuring the water content of the filler, and adjusting the actually measured water content to be 1-2% higher than the optimal water content; 7, mixing by adopting a regenerator, wherein the mixing depth is controlled by adopting a microcontroller; and 8, after the lime-improved weak expansive soil is mixed and rolled, performing compactness detection and maintenance, and after detection is completed, repeating the step 3 to the step 8 to perform construction of the lime-improved weak expansive soil of the next layer of embankment.
本发明公开了一种路堤填料弱膨胀土石灰改良的施工工法，包括以下步骤：一、石灰改良弱膨胀土配比试验；二、对下承层的纵断高程等参数进行检验，以满足施工条件；三、生石灰消解；四、弱膨胀土运至施工现场，弱膨胀土填筑完成后采用推土机粗平并测量标高；五、使用牵引式全自动灰料洒布车进行布灰，采用数控高精度流量调节阀控制石灰洒布数量；六、实测填料含水量，根据实测含水量调整至比最佳含水量高1％～2％；七、采用再生机拌和，拌和深度采用微控制器进行控制；八、石灰改良弱膨胀土拌和，碾压后进行压实度检测和养生，检测完毕后，重复上述步骤三至步骤八进行下一层路堤石灰改良弱膨胀土的施工。
