Novel anchor rod post-grouting pile foundation
The invention provides a novel anchor rod post-grouting pile foundation which comprises a hole digging foundation, anchor rods and miniature threaded pipes, after hole digging of the foundation is completed, anchor rod construction working faces are excavated on the two sides of the foundation, the miniature threaded pipes are drilled into the hole digging foundation according to the design angle, meanwhile, anchor bars are inserted into the miniature threaded pipes, grouting holes are reserved in the upper ends of the miniature threaded pipes, and the grouting holes are formed in the lower ends of the miniature threaded pipes. Uniformly reserved slurry outlets are formed in a pipe body of the micro threaded pipe, the micro threaded pipe is grouted after the foundation is poured and maintained to a certain strength, and a construction working face is backfilled after grouting is completed. According to the scheme, the number and the arrangement form of the miniature threaded pipes can be flexibly adjusted according to actual geological conditions, and adaptability is high; the arrangement position of the anchor rod is very convenient for the drilling and construction of the anchor bar; the stress of the foundation can be effectively increased through the stress of the anchor rod, meanwhile, the hole digging depth of the foundation is reduced, the engineering cost is reduced, the construction progress is accelerated, the labor intensity is reduced, and engineering projects can be completed in areas with complex stratum conditions.
本发明提供了一种新型锚杆后注浆桩基础，包括挖孔基础，锚杆和微型螺纹管，基础挖孔完成后，在基础两侧开挖锚杆施工作业面，将微型螺纹管按照设计角度钻进挖孔基础，同时将锚筋插入到微型螺纹管中，微型螺纹管的上端预留注浆孔，微型螺纹管管身有预留均匀的出浆口，待基础浇筑养护到一定强度，对微型螺纹管注浆，注浆完成后回填施工作业面。本方案中的微型螺纹管的数量及布置形式可以根据实际地质条件灵活调整，适应性强；锚杆的布置位置对锚筋钻入及施工非常便利；通过锚杆的受力，可有效增加基础的受力，同时减少了基础的挖孔深度，减少了工程成本，加快了施工进度，降低劳动强度，又可在复杂的地层条件的地区完成工程项目。
