The invention relates to the field of cast-in-place pile construction, in particular to a pile end post-grouting construction method and a post-grouting device used by the pile end post-grouting construction method. The post-grouting device comprises a reinforcement cage, a plurality of grouting guide pipes are arranged on the outer side of the reinforcement cage and extend from the top to the bottom of the reinforcement cage, and the multiple grouting guide pipes are evenly arranged at intervals; and the bottoms of the grouting guide pipes are in threaded connection with flow guide pipes, the flow guide pipes are parallel to the bottom face of the reinforcement cage, the reinforcement cage extends in the direction away from the flow guide pipes, the multiple flow guide pipes are located on the same plane, the intersection positions of the flow guide pipes arranged in a communicating mode, and a plurality of guniting holes are formed in the side walls of the flow guide pipes. The flow guide pipes extend in the direction deviating from the grouting guide pipes and perform flow guide on the slurry, so that the slurry is evenly dispersed, and the post-grouting device as the advantages that the slurry dispersion uniformity is improved, and the pile end grouting effect is improved.
本申请涉及灌注桩施工的领域，尤其是涉及一种桩端后压浆施工方法及其使用的后压浆装置，其包括钢筋笼，钢筋笼外侧设置有压浆导管，压浆导管从钢筋笼顶部向底部延伸设置，压浆导管设置有多个，多个压浆导管均匀间隔设置，压浆导管底部均螺纹连接有导流管，导流管与钢筋笼底面平行设置，且钢筋笼向着背离导流管的方向延伸，多个导流管位于同一平面，导流管相互交叉处连通设置，导流管的侧壁开设有多个喷浆孔。本申请导流管向着背离压浆导管的方向延伸并对泥浆进行导流，使泥浆均匀分散，具有提高泥浆分散均匀性，提高桩端压浆效果的特点。
