Gravel roadbed backfilling construction method
The invention relates to a gravel roadbed backfilling construction method. The construction method comprises the following steps that S1, garbage around a roadbed is removed, and a foundation pit is dug in the ground; S2, the bottom wall of the foundation pit is compacted, and the pressing depth of the bottom wall of the foundation pit is not smaller than 10 cm; S3, a fixing assembly is laid on the inner side wall of the foundation pit, and the side wall of the foundation pit is fixed; S4, a metal cage net is placed at the inner bottom of the foundation pit, a plurality of reinforcing columnspenetrating through the metal cage net are inserted into the inner bottom wall of the foundation pit, the bottom ends of the reinforcing columns are inserted into soil below the foundation pit, and concrete is poured into the metal cage net to form a metal cage net layer; S5, the upper portion of the metal cage net is filled with gravel, and a gravel layer is formed; S6, a plurality of fixing columns are inserted into the gravel layer, concrete is poured on the gravel layer to form a concrete layer, and the fixing columns are located in the gravel layer and the concrete layer at the same time;and S7, a pavement layer and a waterproof layer are sequentially and fixedly laid on the upper surface of the concrete layer. The method has the effect of reducing the settlement probability of the roadbed.
本申请涉及一种回填砂石路基施工方法，其包括以下步骤：S1、清除路基周围垃圾，并在地面上挖设基坑；S2、将基坑底壁进行压实，并使其下压深度不低于10cm；S3、在基坑内侧壁铺设固定组件，对基坑的侧壁进行固定；S4、往基坑内底部放置金属笼网，往基坑内底壁插设若干将金属笼网贯穿的加强柱，加强柱的底端插入基坑下方的土壤内，并往金属笼网内浇灌混凝土使其形成金属笼网层；S5、往金属笼网上方填充砂石，使其形成砂石层；S6、往砂石层内插入若干固定柱，并往砂石层上浇灌混凝土使其形成混凝土层，固定柱同时位于砂石层与混凝土层内；S7、在混凝土层上表面依次固定铺设路面层和防水层，本申请具有降低路基发生沉降几率的效果。
