Construction technology of bridge underwater cast-in-situ bored pile
The invention discloses a construction process of a bridge underwater cast-in-situ bored pile, relates to the field of bridge pile foundation manufacturing, and aims to solve the problem that a pile foundation below the riverway water level is easy to damage. The technical scheme is characterized in that a steel sleeve is manufactured, the steel sleeve comprises a main body section and a steel ladle ring, and the steel ladle ring is located on the inner side of the lower portion of the main body section; the inner diameter of the steel ladle ring is consistent with the inner diameter of the main body section, the steel ladle ring can be separated from the main body section, and a guide rail assembly is arranged between the steel ladle ring and the main body section and used for limiting separation of the steel ladle ring; drilling a hole site; hoisting the steel sleeve; drilling to form a hole; lowering a reinforcement cage; pouring concrete; and the upper end of the steel sleeve is grabbed through mechanical equipment, the steel sleeve rotates along the guide rail assembly and is upwards hoisted out of the main body section, and the steel ladle ring is left at the bottom of the cast-in-place pile under the action of concrete to form a pile foundation enclosure. According to the construction technology, the steel ladle ring can be arranged around the pile foundation to protect the pile foundation.
本发明公开了一种桥梁水中钻孔灌注桩的施工工艺，涉及桥梁桩基制造领域，旨在解决河道水位以下的桩基容易损坏的问题，其技术方案要点是：制作钢套筒：钢套筒包括主体段与钢包圈，所述钢包圈位于主体段下方内侧，所述钢包圈的内径与主体段的内径保持一致，所述钢包圈可分离于主体段，并且钢包圈与主体段之间设置导轨组件用于限制钢包圈脱离；孔位钻进；吊放钢套筒；钻进成孔；下放钢筋笼；混凝土灌注；吊拔钢套筒：利用机械设备抓取钢套筒上端，沿着导轨组件转动且向上吊出主体段，钢包圈在混凝土的作用下留在灌注桩底部形成桩基围护。本发明的施工工艺能够在桩基周围设置钢包圈对桩基进行保护。
