Anti-settling and anti-sliding bridge cone slope construction method
The invention discloses an anti-settling and anti-sliding bridge cone slope construction method which comprises the following steps: S1, pre-embedded pull rods are distributed in the vertical and horizontal directions when a bridge abutment is poured, and the exposed ends of the pull rods are subjected to anti-corrosion treatment; S2, a layer of backfill soil with a certain thickness is laid and rolled to be compact, the area close to the bridge abutment is tamped manually or through small equipment, the area close to the embankment slope is subjected to step digging treatment, and the whole plate of soil body is completely compacted to be qualified; S3, flexible connecting ribs are laid on the top face of the current layer of backfill soil, slope panels of the current layer are installed on the outer side faces, one ends of the connecting ribs are connected with the pull rods, the other ends of the connecting ribs are connected with the slope panels, and the connecting ribs are in a tightened state; and S4, the step S2 and the step S3 are repeated, construction is conducted upwards layer by layer till cone slope filling is completed, then rib columns are distributed and installed on the outer side faces of the slope panels, and the single rib column is clamped on the outer side faces of all the layers of slope panels at the same time. The cone slope can be prevented from settling and sliding, the shock resistance is good, and the cost is saved.
本发明公开了一种防沉降和抗滑移的桥梁锥坡施工方法，包括步骤，S1、浇筑桥台时沿垂直和水平方向分布预埋拉杆，对拉杆外露端做防锈蚀处理；S2、铺设一层一定厚度的回填土并碾压密实，靠近桥台区域采用人工或小型设备夯实，靠近路堤边坡区域采用挖台阶处理，将整板土体全面压实合格；S3、在当层回填土的顶面铺设柔性的连接筋、外侧面安装当层的坡面板，将连接筋的一端与拉杆连接、另一端与坡面板连接，使连接筋处于紧绷状态；S4、重复步骤S2和步骤S3，逐层往上施工，直至锥坡填筑完成，然后在坡面板外侧面上分布安装肋柱，单根肋柱同时卡在所有层坡面板的外侧面上。能防止锥坡沉降和滑移，抗震好，节约成本。
