Reinforced concrete cast-in-situ bored pile construction process
The invention relates to the field of foundation pit construction, in particular to a reinforced concrete cast-in-situ bored pile construction technology which comprises the steps that S1, a steel sleeve is embedded; the bottom end of the steel sleeve is arranged on the top of a constructed cast-in-place pile in a sleeving mode, and the top end of the steel sleeve is fixedly installed on the ground. S2, sediment located at the top of the constructed cast-in-place pile is removed; s3, discharging the slurry in the drill hole; s4, concrete is poured into the drill holes; and S5, the steel sleeve is pulled out from the underground. The method has the effect that when concrete pouring of the cast-in-place pile is discontinuous, the negative influence of pile breaking is reduced so as to ensure the safety inside and outside the foundation pit.
本申请涉及基坑施工领域,尤其涉及一种钢筋混凝土钻孔灌注桩施工工艺，其包括S1、埋设钢套筒；所述钢套筒的底端套设于已施工灌注桩的顶部，所述钢套筒的顶端固定安装于地面；S2、清除位于所述已施工灌注桩顶部的沉渣；S3、排出钻孔内的泥浆；S4、向所述钻孔内灌注混凝土；S5、将所述钢套筒自地下拔出。本申请具有在灌注桩的混凝土灌注不连续时，减少断桩的负面影响以确保基坑内和基坑外的安全的效果。
