Post-grouting construction method and device for cast-in-place pile
The embodiment of the invention provides a post-grouting construction method and device for a cast-in-place pile, and relates to the technical field of foundation construction, and the method specifically comprises the steps that after a target pile body is formed, at least one pair of closed grouting pipelines is controlled to conduct first grouting on a capsule body; the capsule body is located at the bottom of the target pile body; the closed grouting pipeline is connected with the capsule body; after the first-time grouting is finished, at least one open type grouting pipeline is controlled to conduct second-time grouting on the bottom and the periphery of the target pile body; and the tail end of the open grouting pipeline is connected with the bottom of the pile body and a surrounding rock-soil layer. According to the embodiment of the invention, the post-pile grouting quality can be ensured, and meanwhile, the post-pile grouting efficiency is improved.
本申请实施例提供了一种灌注桩桩后注浆施工方法及装置，涉及地基基础施工技术领域，该方法具体为：待目标桩体成桩之后，控制至少一对闭式注浆管道对胶囊体进行第一次注浆；所述胶囊体位于所述目标桩体底部；所述闭式注浆管道与所述胶囊体连接；待所述第一次注浆结束，控制至少一个开式注浆管道对所述目标桩体底部及周围进行第二次注浆；所述开式注浆管道末端与桩体底部及周围的岩土层连接。本申请实施例能够在保证桩后注浆的质量的同时，提高桩后注浆的效率。
