Construction method suitable for roadbed widening of section adjacent to pond
The invention relates to a construction method suitable for roadbed widening of a section adjacent to a pond. The method comprises the following steps: investigating the natural landform condition of a roadbed widening place adjacent to a pond section on site, establishing an earth weir segmentation water area by measuring on-site paying-off, pumping and draining water constructed in the weir, dredging the thickness of more than 50cm, reinforcing the pit bottom by using a cedarwood pile after dredging, paving a C30 concrete expanded foundation on the top of the cedarwood pile, and paving a C30 concrete expanded foundation on the top of the cedarwood pile. A mortar slice stone retaining wall is built at the upper end of the concrete enlarged foundation, a foundation slope face is tamped, and the section between the inner side faces of the mortar slice stone retaining wall and the concrete enlarged foundation and the tamped three-step-shaped foundation slope face is filled with permeable filler. The external expansion floor area can be reduced, the construction cost is reduced, the construction efficiency is improved, and the stability of the widening structure is ensured.
本发明涉及一种适用于毗邻水塘地段路基加宽的施工方法，包括如下步骤，现场勘察毗邻水塘地段路基加宽所在地的自然地貌状况、通过测量现场放线建立土堰分割水域、对堰内施工的水进行抽排、清淤大于50cm厚、清淤后坑底用杉木桩加固处理、C30混凝土扩大基础铺设在杉木桩的顶部、在混凝土扩大基础上端砌筑浆切片石挡墙、夯实地基斜坡面、在浆切片石挡墙和混凝土扩大基础的内侧面与夯实的三级阶梯状地基斜坡面之间的地段用透水填料填实。本发明能减少外扩占地面积、降低施工费用、提高施工效率，确保加宽结构的稳定性。
