Treatment method for weak expansive soil filled roadbed
The invention discloses a treatment method for a weak expansive soil filled roadbed. The treatment method comprises the following steps that a base of the roadbed needing to be filled with weak expansive soil is treated, a cement soil cushion layer is poured on the base, drainage ditches are formed in the two sides of the cement soil cushion layer, and a slope protection channel is arranged on the upper surface of the cement soil cushion layer; weak expansive soil is filled, the slope ratio of the weak expansive soil side slope is set to be 1: 1.5-1: 1.75, and the two sides of the weak expansive soil are subjected to edge covering treatment through cemented soil; and an anti-seepage composite geomembrane is laid on the upper surface of the filled weak expansive soil to complete treatment of the weak expansive soil filled roadbed. The treatment method for the weak expansive soil filled roadbed has the beneficial effects that the weak expansive soil is reused in the mode that the base of the roadbed is treated, the slope ratio of the weak expansive soil slope is reasonably designed, and the slope surface formed by the weak expansive soil is subjected to edge covering treatment; and by means of the treatment method, the construction efficiency and the construction quality are improved, earthwork is saved, and the construction cost is saved.
本发明公开了一种弱膨胀土填方路基的处理方法，包括以下步骤：对需要使用弱膨胀土填筑的路基的基底进行处理，在基底上浇注水泥土垫层，在水泥土垫层的两侧设置排水沟，在水泥土垫层的上表面设置护坡道；填筑弱膨胀土，设置弱膨胀土边坡坡率为1：1.5‑1：1.75，采用水泥土对弱膨胀土的两侧包边处理；在填筑的弱膨胀土的上表面铺设防渗复合土工膜完成对弱膨胀土填方路基的处理。本申请的有益效果为：本发明所述弱膨胀土填方路基的处理方法，采用对路基的基底进行处理，合理设计弱膨胀土边坡坡率及对弱膨胀土形成的坡面进行包边处理的方式实现了弱膨胀土的再次利用，且采用本申请所述处理方法提高了施工效率及施工质量，节省了土方，节约了施工成本。
