Construction method of foundation slab with anti-floating anchor rod
The invention relates to a construction method of a foundation slab with anti-floating anchor rods, which comprises the following steps: after cushion layer concrete is poured, punching and installing the anti-floating anchor rods, after one-time grouting of all the anti-floating anchor rods on a construction surface is completed, immediately constructing foundation slab steel bars, and reserving construction holes in the positions of all the anti-floating anchor rods when the foundation slab is poured; after anchor rod hole concrete reaches non-hundreds of strength and the surface of the foundation slab reaches the strength of an anchor rod anti-pulling test detection construction surface, part of anti-floating anchor rods are randomly selected in proportion for detection, anchor rod detection equipment is arranged on the surface of the foundation slab, and the anti-floating anchor rods are pulled by adopting rated force required by design; if the anti-floating anchor rod is stable, the detection is qualified; after the anti-floating anchor rods are detected to be qualified, anchoring ribs of the anti-floating anchor rods are bound and fixed to the upper row of steel bars of the foundation bottom plate; according to the construction method, the anti-floating anchor detection step is adjusted to be after the foundation slab is poured, cross operation can be conducted on foundation slab construction and anti-floating anchor detection, and the total construction period is shortened.
本发明涉及一种带抗浮锚杆的基础底板施工方法，垫层混凝土浇筑后，打孔安装抗浮锚杆，施工面上所有抗浮锚杆一次的注浆完毕后，立即施工基础底板钢筋，浇筑基础底板时在每个抗浮锚杆位置预留施工孔；等待锚杆孔混凝土达到非分百强度，以及基础底板表面达到作为锚杆抗拔试验检测施工面强度后，按比例随机选取部分抗浮锚杆进行检测，在基础底板表面设置锚杆检测设备，采用设计要求额定的力拉拔抗浮锚杆，若抗浮锚杆稳定则为检测合格；抗浮锚杆检测合格后，将抗浮锚杆的锚固筋与基础底板上排钢筋绑扎固定；浇筑所有施工孔，本发明将抗浮锚杆检测步骤调整到基础底板浇筑之后，基础底板施工与抗浮锚杆检测可以进行交叉作业，缩短总工期。
