High-pile cushion cap foundation based on swirling pile and construction method thereof
The invention belongs to the technical field of structural foundations, and discloses a high-pile cushion cap foundation based on a swirling pile and a construction method thereof. The lower part of acushion cap is connected with a vertical swirling pile and a plurality of inclined swirling piles, and the top of the cushion cap is connected with a central cylinder; at least one layer of whirlingbearing blades are arranged on the outer side of soil entry sections of the vertical swirling pile and the inclined swirling piles, stiffening ribs are arranged on the outer side of a section connected with the cushion cap, and shear keys are arranged on the inner side of the section connected with the cushion cap. During the construction, the vertical swirling pile is driven to the design elevation firstly; then a platform formwork is erected on the upper part of the vertical swirling pile, the cushion cap is installed, and the vertical swirling pile is in grouting connection with the cushioncap; then, the inclined swirling piles are inserted and driven to the design elevation through the cushion cap, and the inclined swirling piles are in grouting connection with the cushion cap; and finally, the central cylinder is in grouting connection with the cushion cap. According to the high-pile cushion cap foundation based on the swirling pile and the construction method thereof, the foundation stability is good, the construction and installation are convenient, the installation cost is low, and the high-pile cap foundation can be widely used in practical projects.
本发明属于结构基础技术领域，公开了一种基于打旋桩的高桩承台基础及其施工方法，承台下部连接有一根竖直打旋桩和多根斜打旋桩，承台顶部连接有中心筒；竖直打旋桩和斜打旋桩的入土区段外侧均设置有至少一层打旋承载叶片，与承台的连接区段外侧均设置有加劲肋、内侧均设置有剪力键。施工时，先将竖直打旋桩打桩至设计高程；然后在竖直打旋桩上部支设平台模板并安装承台，将竖直打旋桩与承台灌浆连接；再将斜打旋桩通过承台插入并打桩至设计高程，将斜打旋桩与承台灌浆连接；最后将中心筒与承台灌浆连接。本发明的基础稳定性较好，施工安装方便，安装成本较低，可使高桩承台基础更广泛的应用于实际工程。
