Oblique rock-socketed cast-in-place pile type high pile cap foundation and construction method
The invention provides an inclined rock-socketed cast-in-place pile type high-pile bearing platform foundation which comprises a bearing platform, a transition section tower barrel is arranged in the center area of the bearing platform, an array type inclined pile system is arranged at the bottom of the bearing platform, and a prefabricated sealing bottom used for a rock-socketed construction platform supporting structure is arranged on the connecting face of the bearing platform and the array type inclined pile system. The method has the advantages of being high in rock debris discharging capacity, not prone to blockage, small in equipment abrasion, long in drill bit service life, high in drilling efficiency and good in hole forming quality, hole wall collapse accidents are not prone to happening in construction in unconsolidated strata, the prefabricated sealing bottom is reserved to serve as a part of the bearing platform, construction platforms are convenient to build, the stability of the construction platforms is improved, and the construction cost is reduced. And the construction cost is reduced.
本发明提供一种斜嵌岩灌注桩式高桩承台基础，包括承台，所述承台中心区域为过渡段塔筒，所述承台底部设有阵列式斜桩系统，所述承台与阵列式斜桩系统连接面设有用于嵌岩施工平台支撑结构的预制封底。本发明采用方法具有排岩屑能力强，不易堵塞，设备磨损小，钻头寿命长，钻进效率高，成孔质量好，在松散地层中施工不易发生孔壁坍塌事故以及保留预制封底作为承台的一部分，既方便了施工平台的搭建，增加了施工平台的稳定性，又降低了施工成本等优势。
