Support construction method using anti-floating anchor rods for replacing raft stirrups
The invention discloses a support construction method using anti-floating anchor rods for replacing raft stirrups, and belongs to the technical field of raft construction. The support construction method using the anti-floating anchor rods for replacing the raft stirrups is characterized by comprising the following steps: 1) hole formation for a foundation pad and the anti-floating anchor rods iscarried out, and the anti-floating anchor rods are placed in the holes; 2) grouting for the anti-floating anchor rods and repair for the pad are carried out; 3) construction for waterproof additionallayers of the anti-floating anchor rods is carried out; 4) the anti-floating anchor rods are bent into the stirrups; and 5) steel bars of a raft are bundled, bundling construction is carried out on the steel bars at the bottom of the raft according to an arrangement distance, the upper-part steel bars are erected at the tops of the anti-floating anchor rods, and bundling or welding fixation is carried out on the steel bars of the anti-floating anchor rods and the upper-part bars of the raft. According to the support construction method using the anti-floating anchor rods for replacing the raftstirrups, the holes are drilled in the foundation pad, the anti-floating anchor rods are installed in the holes, the anti-floating anchor rods are bent according to a calculated elevation, horizontalsteel bars are not located on the same straight line after being bent, the bent sections of the anti-floating anchor rods are taken as the stirrups, foundation upper-skin steel bars start to be bundled, and finally the anti-floating anchor rods and the raft are connected into one piece; and the structure is capable of effectively resisting an underground water buoyancy.
抗浮锚杆代替筏板马凳筋支撑施工方法，属于筏板施工技术领域。其特征在于：包括以下步骤，1）基础垫层及抗浮锚杆成孔，孔内放置抗浮锚杆；2）抗浮锚杆注浆、垫层修补；3）抗浮锚杆防水附加层施工；4）将抗浮锚杆弯折制成马凳筋；5）筏板钢筋绑扎，筏板底部钢筋按照排列间距绑扎施工，将上部钢筋架设在抗浮锚杆顶部，抗浮锚杆钢筋与筏板上部筋进行绑扎或焊接固定。本发明在基础垫层上钻孔，并在孔内安装抗浮锚杆，将抗浮锚杆按照计算标高进行弯折，弯折后水平钢筋不在一条直线上，抗浮锚杆弯折段作为马凳，开始绑扎基础上皮钢筋，最后将抗浮锚杆与筏板连成整体，这种结构可有效抵抗地下水浮力。
