The invention discloses a soft clay foundation treatment method suitable for municipal road pipeline laying, which comprises the following steps of: 1, determining the depth of a soft clay layer of a to-be-treated site according to investigation data; secondly, the stratum of the site to be treated is divided into a soil filling layer, a foundation layer and a reinforcing layer from shallow to deep; thirdly, original soil is excavated out of the soil filling layer, and a high-pressure jet grouting pile is adopted to reinforce a reinforcing layer foundation along the line where the pipeline needs to be laid; fourthly, cement mixing piles are constructed on the reinforcing layer foundations on the two sides of the high-pressure jet grouting piles to form an anti-seepage curtain; fifthly, a sewage pipe pipeline is arranged on the reinforcing layer, a rainwater pipe pipeline is arranged on the foundation layer, and part of the rainwater pipe pipeline and a rainwater and sewage branch pipe pipeline are arranged on the soil filling layer; and sixthly, slag and soil clamping backfilling is conducted on the soil filling layer, and layered filling and tamping are conducted. According to the soft clay foundation treatment method suitable for municipal road pipeline laying, the soft clay foundation is subjected to layered treatment according to the requirements of different pipelines, the treatment efficiency is high, and the foundation reinforcement effect is good.
本发明公开了一种适用于市政道路管线铺设的软黏土地基处理方法，包括以下步骤：第一步，根据勘察资料，确定待处理场地软黏土层所处深度；第二步，将待处理场地地层由浅至深分为填土层、基础层、加固层；第三步，将填土层挖除原土，采用高压旋喷桩对需铺设管线沿线的加固层地基进行加固；第四步，在高压旋喷桩两侧的加固层地基施工水泥搅拌桩形成防渗帷幕；第五步，在加固层设置污水管管道，在基础层设置雨水管管道，在填土层设置部分雨水管管道及雨污水支管管道；第六步，在填土层做宕渣夹土回填，分层填筑夯实。本发明所述的适用于市政道路管线铺设的软黏土地基处理方法，针对不同管线的需要将软黏土地基分层处理，处理效率高，地基加固效果好。
