Post-grouting construction method for post-inserted reinforcement cage pile bottom of cast-in-place concrete pile
The invention belongs to the technical field of cast-in-place pile construction, and particularly relates to a post-grouting construction method for the post-inserted reinforcement cage pile bottom ofa cast-in-place concrete pile. The post-grouting construction method comprises the following specific steps that (1) a reinforcement cage is manufactured, and a grouting pipe is bound and fixed on the reinforcement cage; (2) a pile casing is embedded in the pile position, and then a drilling machine is used for drilling a soil layer to obtain a pile hole; (3) concrete grout is poured into the pile hole to manufacture a concrete pile; (4) before initial setting of the concrete pile, the reinforcement cage bound with the grouting pipe is inserted into the concrete pile; (5) a geological drilling machine is used for penetrating through the bottom of the grouting pipe, the bottom of the concrete pile is drilled, and the grouting pipe is dredged with water; and (6) grouting is carried out on the bottom of the concrete pile by using the grouting pipe. Compared with an existing construction mode of firstly inserting the reinforcement cage and then pouring the concrete, the mode of firstly pouring the concrete and then inserting the reinforcement cage is adopted, and the bearing effect of a poured pile body can be improved.
本发明属于灌注桩施工技术领域，具体涉及一种混凝土灌注桩后插钢筋笼桩底后注浆施工方法，具体步骤如下：（1）制作钢筋笼，并在钢筋笼上绑扎固定注浆管；（2）在桩位处埋入护筒，然后用钻机对土层钻孔得到桩孔；（3）向桩孔中灌注混凝土浆液，制成混凝土桩；（4）在混凝土桩初凝前，将绑扎有注浆管的钢筋笼插入混凝土桩内；（5）用地质钻机穿过注浆管底部并将混凝土桩底部钻通，并用水将注浆管进行疏通；（6）利用注浆管向混凝土桩底部进行注浆。与现有先插钢筋笼后灌注混凝土的施工方式相比，本发明采用先灌注混凝土后插钢筋笼的方式，能够提高灌注后的桩体的承载效果。
