Combined type post-grouting construction method for cast-in-situ bored pile
The invention relates to a cast-in-situ bored pile post-grouting construction method, in particular to a cast-in-situ bored pile composite post-grouting construction method. Comprising the following steps: (1) determining design parameters through a manufacturability test; (2) drilling the cast-in-place pile; (3) mounting a reinforcement cage and a steel plate capsule; (4) pile foundation concrete is poured through a guide pipe; (5) detecting a pile body; (6) post-grouting construction; the method is used for post-grouting construction of the cast-in-situ bored pile, design parameters are determined through a manufacturability test, grouting reinforcement is conducted on the pile bottom and the pile periphery by pre-burying the grouting pipe and the pile bottom steel plate capsule in the cast-in-situ pile, the pile bottom foundation bearing capacity and the pile periphery friction resistance are improved, and on the premise that the pile foundation bearing capacity is guaranteed, the pile length of a pile foundation is reduced, and the engineering cost is saved.
本发明涉及钻孔灌注桩后压浆施工方法，具体涉及一种钻孔灌注桩复合式后压浆施工方法；包括以下步骤：（1）工艺性试验确定设计参数；（2）灌注桩钻孔；（3）钢筋笼、钢板胶囊安装；（4）采用导管灌注桩基混凝土；（5）桩身检测；（6）后压浆施工；本发明用于钻孔灌注桩后压浆施工，通过工艺性试验确定设计参数，通过对灌注桩预埋压浆管与桩底钢板胶囊,对桩底、桩周进行注浆加固，提升桩底地基承载力及桩周摩阻力，在保证桩基承载力的前提下，减少桩基桩长，节省工程造价。
