High-rise building foundation pile foundation construction method

CAO YANPING

The invention provides a high-rise building foundation pile foundation construction method. The high-rise building foundation pile foundation construction method uses high-rise building foundation pile foundation construction equipment, and the high-rise building foundation pile foundation construction equipment comprises a limiting device and a butt joint device. According to the high-rise building foundation pile foundation construction method, a pile casing needs to be buried before drilling of a cast-in-situ bored pile to prevent hole wall collapse during drilling, the following problems, still existing in the pile casing burying process, that, a, hole digging is carried out on the ground through a drilling machine, then the pile casing is placed in the hole through a crane, effective and vertical positioning is not carried out on the pile casing in the process, the pile casing cannot be ensured to be in a vertical state, so that the positioning of the drilling machine during subsequent drilling is influenced, and a drilled formed hole is inclined; and b, most of the embedded pile casing is a round pile casing with higher height, so that the pile casing is difficult to vertically position when being buried, and the pile casing is often installed to be inclined can be solved.

本发明提供了一种高层建筑地基桩基施工方法，其使用了高层建筑地基桩基施工设备，该设备包括限位装置和对接装置。本发明可以解决钻孔灌注桩在钻孔之前需要埋设护筒，防止钻孔时出现孔壁坍塌，而护筒在埋设过程中依旧存在的以下难题：a.通过钻机在地面上进行挖孔，然后将护筒通过吊机放置在孔内，而在这个过程中没有对护筒进行有效竖直定位，无法保证护筒处于竖直状态，影响后续钻孔时钻机的定位，导致钻出的成孔有倾斜现象；b.埋设的护筒大多是一个具有较高高度的圆形护筒，使得护筒埋设时对其竖直定位较为困难，经常存在护筒安装歪斜。
