Pile cap foundation with high stability and construction method of pile cap foundation

WANG LINFEI / XIA ZHIQIANG / WANG FENG / ZHANG XIANG

The invention particularly provides a pile cap foundation with high stability and a construction method of the pile cap foundation. The problems that an existing pile cap foundation is not good in ground gripping effect, and easily settles, so that the stability is affected are solved. According to the pile cap foundation with high stability, multiple short strip-shaped grooves and multiple long strip-shaped grooves are formed in the side face of each body pile column in the axial direction, and the upper ends of the short strip-shaped grooves and the upper ends of the long strip-shaped grooves communicate with the upper end faces of the body pile columns. The lower ends of the short strip-shaped grooves and the lower ends of the long strip-shaped grooves are sealed. Expansion forming frames are embedded into each short strip-shaped groove and each long strip-shaped groove. The middles of the expansion forming frames expand outwards in the radial directions of the body pile columns. The effect of enhancing the ground gripping effect is achieved, a multi-directional supporting structure is formed, the pile cap foundation can be effectively prevented from settling, pile sinking and impact are facilitated, and the operability of the construction process is effectively improved.

本发明具体是一种高稳定性的桩承台基础及其施工方法，解决了现有桩承台基础存在抓地效果不好、易发生沉降影响稳定性的问题。一种高稳定性的桩承台基础，每根主体桩柱的侧面均沿轴向开设有若干个短条形凹槽与若干个长条形凹槽，各个短条形凹槽的上端、各个长条形凹槽的上端均与主体桩柱的上端面贯通；各个短条形凹槽的下端、各个长条形凹槽的下端均封闭；每个短条形凹槽的内部、每个长条形凹槽的内部均嵌设有一个扩张成型架；各个扩张成型架的中部均沿主体桩柱的径向向外扩张。本发明实现了增强抓地效果的目的，形成多方向的支撑结构，能够有效防止本发明发生沉降，方便沉桩，方便冲击，有效提高了施工过程的可操作性。
