支盘灌注桩施工的关键

Construction of branch squeezed cast-in-site pile

支盘灌注桩是在等截面的钻孔灌注桩基础上发展起来的一种变截面桩。介绍了由于支盘灌注桩中设置承力盘 ,桩周表面积大 ,桩顶承受荷载时 。

Branch squeezed cast in site pile is a pile with variable cross section, which developed from cast in site bored pile. Because of bearing disks the specific surface is increased. Obvious time and order effects can be developed through side friction of pile and end resistance of bearing disks subjected to load.
