The invention relates to a construction method for improving the concrete compactness of a bored pile in engineering, which comprises the following steps: S1, after mechanically forming a hole, placing a reinforcement cage in the hole, hoisting a grouting pipe into the hole along with the reinforcement cage, moving the grouting pipe into an area enclosed by the reinforcement cage, and descending the grouting pipe in an initial state until a certain distance is reserved between the grouting pipe and the bottom of the hole; s2, concrete is poured into the hole through a grouting pipe, the mode of layer-by-layer pouring and layer-by-layer compaction is adopted, in other words, after each layer of concrete is poured, the layer of concrete is compacted through a compaction plate arranged on the grouting pipe, and in the process, the grouting pipe ascends layer by layer; and S3, after concrete pouring in the whole hole is completed, the grouting pipe also ascends and moves out of the hole, and construction of the bored pile is completed. According to the bored pile, the construction mode of layer-by-layer pouring and layer-by-layer compaction is adopted, the compactness of concrete can be improved, and then the stability of the whole bored pile is improved.
本申请涉及一种提高工程中钻孔桩砼密实度的施工方法，其包括步骤S1：机械成孔后，朝孔内安放钢筋笼，注浆管随同钢筋笼一起吊放至孔内，移动注浆管至钢筋笼所围设的区域内，且初始状态时将注浆管下降至与孔底留有一定间距；步骤S2：通过注浆管朝孔内灌注混凝土，采用逐层灌注逐层压实的方式，即每灌注一层混凝土后，便通过设置在注浆管上的压实板将该层混凝土压实，在此过程中，注浆管也逐层的上升；步骤S3：直至整个孔内混凝土灌注完毕后，此时注浆管也上升移至孔外，即完成钻孔桩的施工。本申请的钻孔桩采用逐层灌注逐层压实的施工方式，可提高混凝土的密实度，进而提高整个钻孔桩的稳定性。
