Unfavorable geological condition roadbed construction method
The invention discloses an unfavorable geological condition roadbed construction method which comprises the following steps: step 1, cleaning sundries on the earth surface, and excavating a soft soil foundation; step 2, paving rubbles, compacting, filling backfill materials, and compacting to form a substrate layer; 3, geotextile is laid, graded broken stone is laid and compacted, an anti-sedimentation structure is installed, then the anti-sedimentation structure is filled with the graded broken stone till the graded broken stone covers the anti-sedimentation structure, compaction is conducted, and an anti-sedimentation layer is formed; the anti-sedimentation structure comprises a bottom frame which is in a sphere-like shape and has an upward opening; the bottoms of the supporting columns are movably arranged on the bottom frame in a limiting manner; the top cover comprises a plurality of top frames which are sequentially in mutual limiting lap joint in the transverse direction of the roadbed, the top cover is in a sphere-like shape, an opening faces downwards, the top frames are movably connected to the tops of the supporting columns in a limiting and covering mode, and the top cover is in the shape with the middle higher than the two sides in the transverse direction of the roadbed; 4, geotextile is laid; fifthly, concrete is poured; and step 6, paving asphalt concrete, and compacting to form a pavement. The method has the beneficial effect of preventing pavement settlement under unfavorable geological conditions.
本发明公开了一种不良地质条件路基施工方法，包括：步骤一、清理地表杂物，开挖软土地基；步骤二、铺装片石，压实，填充回填料，压实，形成基底层；步骤三、铺装土工布，铺装级配碎石，压实，安装防沉降结构，再填充级配碎石直至盖过防沉降结构，压实，形成防沉降层；防沉降结构包括：底架，其呈类球面形，开口朝上；多个支柱，底部限位活动设置于底架上；顶盖，其包括沿路基横向依次相互限位搭接的多个顶架，呈类球面形，开口朝下，顶架限位活动盖接于支柱顶部，顶盖沿路基横向呈中间高两侧低的形状；步骤四、铺装土工布；步骤五、浇注混凝土；步骤六、铺装沥青混凝土，压实，形成路面。本发明具有防止不良地质条件下路面沉降的有益效果。
