PHC slant socketed pile construction method
The invention relates to the technical field of cast-in-place concrete pile construction, in particular to a PHC slant socketed pile construction method which is used for PHC pipe pile and socketed core construction, the PHC pipe pile comprises a straight pile and an inclined pile, the inclined pile and the straight pile of the PHC pipe pile are hit, pile sinking is completed, an inner hole of the PHC pipe pile is drilled through a percussion drill after pile sinking, and before drilling, the inner hole of the PHC pipe pile is drilled through a percussion drill; according to the construction method, a hollow hammer head and a construction device are improved, the construction process of the PHC slant socketed pile is smoothly completed, and the construction method comprises the steps of drilling, grouting, hole cleaning and inspection, reinforcement cage manufacturing, transportation and installation, socketed core concrete pouring and finally pile forming detection, and the construction method successfully solves the problem that the bearing capacity of a PHC pile foundation is low; on the premise that large equipment is not adopted, the stability of the PHC prefabricated pipe pile can be improved, through the construction mode of drilling and pouring the rock-socketed core, the stability of a pile foundation is good, and control over the engineering cost and safety input is greatly facilitated.
本发明涉及混凝土灌注桩施工技术领域，尤其涉及一种PHC斜向嵌岩桩施工方法，该施工方法对PHC管桩及嵌岩芯施工，PHC管桩包括直桩和斜桩，通过对PHC管桩的斜桩及直桩施打，完成沉桩，沉桩后再PHC管桩内孔采用冲击钻机钻孔，钻孔前，对空心锤头及施工装置进行改进，顺利完成PHC斜向嵌岩桩的施工过程，包括钻孔，注浆清孔及检验，钢筋笼制作、运输及安装，以及灌注嵌岩芯混凝土，最后进行成桩检测，这一施工方法成功解决了PHC桩桩基承载力较低的问题，在不采用大型设备的前提下，就能提高PHC预制管桩的稳定性，通过钻孔、浇筑嵌岩芯的施工方式不仅桩基稳定性好，而且对控制工程成本造价及安全投入也大有帮助。
