Method for girdling-free pile head of cast-in-place pile
The invention provides a pile head girdling-free method for a cast-in-place pile. The girdling-free cast-in-place pile is adopted. The girdling-free cast-in-place pile is provided with a reinforcement cage, the reinforcement cage is provided with longitudinal bars arranged in a circumferential array mode, circular hoops are evenly arranged on the outer sides of the longitudinal bars in the axial direction of the longitudinal bars, the circular hoops are fixedly connected with the longitudinal bars, and pile head bars are arranged at the upper ends of the longitudinal bars. A partition plate is arranged on the pile head rib, a pouring opening is formed in the center of the partition plate, a pipe connector matched with the pile head rib is arranged on the partition plate, a partition pipe is detachably connected to the upper end of the pipe connector, and at least four device cavities are formed in the top of the partition plate in a circumferential array mode. A hydraulic telescopic component is arranged in the device cavity, and a push plate is arranged at the bottom of the hydraulic telescopic component. According to the girdling-free pile head method for the cast-in-place pile, the girdling-free cast-in-place pile is adopted, manpower expenditure can be reduced, less dust is generated in the pile head breaking process, the construction speed can be remarkably increased, and the construction progress can be accelerated.
本发明提供一种灌注桩免环切桩头方法，采用免环切灌注桩；所述免环切灌注桩具有钢筋笼，所述钢筋笼具有呈圆周阵列设置的纵筋，所述纵筋的外侧沿其轴向均匀设置有圆箍，所述圆箍与纵筋之间固定连接，所述纵筋的上端为桩头筋；所述桩头筋上设置有分隔板，所述分隔板的中心开设有灌注口，所述分隔板上设置有与所述桩头筋相匹配的管接头，所述管接头的上端可拆卸连接有分隔管，所述分隔板的顶部呈圆周阵列有至少四个装置腔，所述装置腔的内部设置有液压伸缩部件，所述液压伸缩部件的底部设置有推板；本发明中的灌注桩免环切桩头方法，采用免环切灌注桩能够减少人力支出，破桩头过程中产生粉尘较少，并且能够显著提升施工速度，加快施工进度。
