Soft soil roadbed treatment method
The invention relates to a soft soil roadbed treatment method. The method comprises the following steps of excavating a soft soil layer along a roadbed to a designed replacement depth, and paving lower-layer anti-seepage geotechnical cloth; two layers of lead wire nets being laid on the lower-layer anti-seepage geotechnical cloth, a rubble layer with a certain thickness being laid on the lead wire nets according to the designed width of the roadbed, then the two sides, the two ends and the top face of the rubble layer being completely wrapped with the lead wire nets, and a lead wire cage wrapping the rubble layer being formed; laying upper-layer anti-seepage geotechnical cloth on a top surface of the lead wire cage; and filling the upper-layer anti-seepage geotechnical cloth to the designed height of the roadbed by using the replacement filling soil, and paving a pavement structure layer. The method is suitable for roadbed construction of a thick soft soil layer, the roadbed soft soil replacement depth can be reduced, the construction progress is accelerated, and overall stability of the roadbed is guaranteed.
本发明涉及一种软土路基处置方法，将路基沿线软土层开挖到设计换填深度后，铺设下层防渗土工布；在下层防渗土工布上铺设两层铅丝网，在铅丝网上按路基设计宽度铺设一定厚度的片石层，然后用铅丝网将片石层两侧、两端及顶面完全包裹，形成裹紧片石层的铅丝笼；在铅丝笼顶面铺设上层防渗土工布；在上层防渗土工布上用换填土填筑到路基设计高度，并铺筑路面结构层。本发明适用于较厚软土层的路基施工，能减少路基软土换填深度，加快施工进度，并保证路基整体稳定性。
