Settlement prevention method for bridge pile foundation
The invention relates to a settlement prevention method for a bridge pile foundation. The settlement prevention method comprises the following steps of (S1) excavating a foundation pit at a specified soil layer, and paving a compensation layer above the foundation pit; (S2) paving a first concrete layer on the compensation layer, and fixing a screw pile of the pile foundation to the interior of the first concrete layer after a positioning block of the pile foundation is fixed to the pile foundation; (S3) paving a second concrete layer between the first concrete layer and the lower part of a bearing platform after the bearing platform is placed on the upper end face of the pile foundation; and (S4) paving a backfill soil layer on the second concrete layer and tamping. According to the settlement prevention method, the pile side friction resistance and the bearing capacity of the pile foundation are improved, and settlement is slowed down.
本发明涉及一种桥梁桩基的防沉降方法，包括如下步骤：S1、在指定的土层处开挖基坑，在基坑的上方铺筑补偿层；S2、在补偿层的上方铺筑第一混凝土层，将桩基的定位块与桩基固定好之后，将桩基的螺杆桩固定于第一混凝土层内；S3、在桩基的上端面安放承台后，在第一混凝土层和承台的下方之间铺筑第二混凝土层；S4、在第二混凝土层的上方铺筑回填土层并夯实；本发明提供的防沉降方法，提高桩侧摩阻力和桩基的承载力，减缓沉降的发生。
