Pile foundation concrete multi-guide-pipe pouring auxiliary system and pouring method
The invention relates to a pile foundation concrete multi-guide-pipe pouring auxiliary system and a pouring method, the pile foundation concrete multi-guide-pipe pouring auxiliary system comprises a pouring system, the pouring system comprises a large hopper, a plurality of small hoppers and a plurality of guide pipes, the large hopper is communicated with the small hoppers, each small hopper is communicated with one guide pipe, and the guide pipes are used for stretching into a drill hole; each guide pipe forms a concrete pouring channel; the partition system comprises a plurality of bin partition plates and a plurality of annular plates, the annular plates are vertically arranged and used for being arranged in a pile foundation bottom reinforcement cage, the bin partition plates are fixed in the annular plates, and the interiors of the annular plates are divided into a plurality of concrete pouring partitions; and the plurality of concrete pouring channels are in one-to-one correspondence with the plurality of concrete pouring subareas. The length of a concrete spreading path corresponding to a single guide pipe is shortened, uneven pile body quality and guide pipe blockage are avoided, and the pile forming quality is guaranteed; and the formation of a slurry interlayer soft interface in the section of the pile bottom by concrete in each subarea is avoided.
本申请涉及一种桩基混凝土多导管灌注辅助系统及灌注方法，其包括：灌注系统，其包括大料斗、多个小料斗和多根导管，所述大料斗与多个所述小料斗连通，每个所述小料斗与一根所述导管连通，所述导管用于伸入钻孔内，每个导管形成一条混凝土灌注通道；分区系统，其包括多块分仓隔板和多个环板，多个所述环板竖向设置，并用于设置于桩基底部钢筋笼内，多块所述分仓隔板固定于所述环板内，将所述环板的内部分割成多个混凝土灌注分区；多条所述混凝土灌注通道与多个所述混凝土灌注分区一一对应。缩短了单根导管对应的混凝土摊开路径长度，避免出现桩身质量不均和发生导管堵塞，保证成桩质量；避免各个分区混凝土在桩底断面内形成泥浆夹层软弱界面。
