Construction method of roadbed shallow foundation reinforcing structure in plain area
A construction method of a subgrade shallow foundation reinforcing structure in a plain area comprises the following steps: forming a reinforcing main body of a shallow foundation by adopting a combined structure of capillary waterproof and drainage plates, a sand cushion layer, an anti-seepage geomembrane in a soil ditch, a lime soil cushion layer and impact rolling; if capillary water and underground water are separated by arranging the permeable geomembrane; due to the arrangement of the sand cushion layer, the drainage capacity of underground water is enhanced; an anti-seepage geomembrane is arranged in the earth ditch to prevent underground water from infiltrating after being drained into the earth ditch, so that the drainage efficiency is improved; the lime soil cushion layer is arranged to play a sealing role; an anti-seepage geomembrane is adopted in the ditch, and permanent and temporary combination is adopted, so that infiltration of underground water is avoided, improvement of soil body strength is facilitated, and drainage efficiency is improved; a lime soil cushion layer is adopted, underground water is sealed to rise, the overall strength of a soil body is improved, a working face is provided for impact rolling, the dynamic consolidation effect within the range of 3m of a shallow layer is remarkable, and rubber soil is avoided.
一种平原地区路基浅层地基加固结构的施工方法，通过采用毛细防排水板+砂垫层+土沟内防渗土工膜+灰土垫层+冲击碾压的组合结构形成浅层地基的的加固主体，通过若分段分块毛细防排水板设置疏排毛细水、地下水，若通过设置渗土工膜隔断毛细水、地下水；砂垫层的设置增强了地下水的疏排能力；土沟内设置防渗土工膜避免地下水排入土沟后下渗，提高排水效率；灰土垫层设置，起到封闭作用；沟内采用防渗土工膜，永临结合，避免了地下水的下渗，有利于土体强度的提高，提高了排水效率；采用灰土垫层，封闭地下水上升，提高土体整体强度，为冲击碾压提供工作面，浅层3m范围内动力固结效果显著，避免橡皮土。
