Construction method for installing and positioning pile foundation reinforcement cage
The invention provides a construction method for installing and positioning a pile foundation reinforcement cage, and belongs to the technical field of cast-in-situ bored pile construction of bridge foundations and lower structures. The construction method comprises the steps that after a pile foundation is formed, the center position (6) of the pile foundation is determined; the reinforcement cage (8) is placed at the center position (9) of the reinforcement cage (8), and when the reinforcement cage (8) is about to get close to slurry, an empty bottle (3) penetrates through the position below the center position (9) of the reinforcement cage; a plumb bob (4) is hung through the center position (6) of the pile foundation; the empty bottle (3) floats on the slurry; and whether the center position (10) of the empty bottle (3) coincides with the center position (11) of the plumb bob or not is observed, if yes, that the reinforcement cage (8) is placed in place is indicated, and the reinforcement cage (8) is fixed. According to the construction method for installing and positioning the pile foundation reinforcement cage, the reinforcement cage can be conveniently and accurately positioned, construction can be conducted through the buoyancy of the slurry and the plumb bob, the pile position deviation is reduced, subsequent stand column construction is facilitated, and the reinforcement cage can be repeatedly used.
本发明提供一种应用于桥梁基础及下部构造的钻孔灌注桩施工技术领域的桩基钢筋笼安装定位的施工方法，桩基成孔后，确定桩基中心位置(6)；确定钢筋笼(8)的钢筋笼中心位置(9)下钢筋笼(8)，待钢筋笼(8)快要接近泥浆时，将空瓶(3)从钢筋笼中心位置(9)下面穿过；利用桩基中心位置(6)，吊铅锤(4)；使空瓶(3)浮在泥浆上；观察空瓶(3)的空瓶中心位置(10)是否与铅锤的铅锤中心位置(11)重合，如果重合，表明钢筋笼(8)下放到位，固定钢筋笼(8)，本发明所述的桩基钢筋笼安装定位的施工方法，能够方便准确实现钢筋笼定位，利用泥浆浮力与铅锤便可施工，降低桩位偏差，便于后续立柱施工，可以重复利用。
