Construction method for anti-settlement expressway roadbed in soft soil area
The invention discloses a construction method for an anti-sedimentation expressway roadbed in a soft soil area. The construction method comprises the following steps: S1, surveying and setting out; s2, digging a drainage channel; s3, surface layer cleaning treatment is conducted on the foundation treatment range, and the removed plant rhizomes are placed in a specified treatment site; s4, the surface of the foundation is flattened and rolled, the compaction degree cannot be lower than 90%, the gravity load of the subgrade surface cannot exceed the specified range in the extrusion process, and the compaction range is controlled to be 50 cm away from the outside of a subgrade filling slope toe line; s5, the compacted soft soil roadbed is irradiated by the sun; s6, earth excavation is conducted on the road surface base, after excavation, roadbed supporting inclined plates are added to separate the interior of the road surface base, a gravel cushion layer is filled, and a concrete layer is poured after earth filling; and S7, padding is laid on the surface of the concrete layer to form a padding layer, sandy soil is laid on the surface of the padding layer to form a sandy soil layer, and a pavement layer is laid on the sandy soil layer. By arranging the filler layer, the deformation resistance of the roadbed can be enhanced, and the settlement condition is relieved.
本发明公开一种软土区防沉降高速公路路基施工方法，包括：S1、测量放样；S2、挖设排水槽；S3、对地基处理范围进行表层清洁处理，将清除的植物根茎放置到规定的处理地点；S4、对地基表面进行平整碾压工序，压实度不能低于90％，挤压过程中注意路基面的重力负载不能超过规定的范围，实压范围控制在路基填方坡脚线向外50cm以外；S5、将压实后的软土路基通过太阳照射；S6、进行路面基地土方开挖，开挖后，加入路基支撑斜板进行分隔路面基地内部，并填入砂石垫层，填土后浇筑混凝土层；S7、在混凝土层表面铺设填料，形成填料层，并在填料层表面铺设砂土，形成砂土层，在砂土层上铺设路面层。通过设置填料层，能够增强路基的抗变形能力，减轻沉降状况。
