Anti-floating anchor rod and construction method thereof
The embodiment of the invention provides an anti-floating anchor rod and a construction method thereof, a plurality of anchor rod holes are formed perpendicular to a bearing stratum, a protective pipe is pre-buried at the upper end of each anchor rod hole, then a prefabricated anchor rod steel strand is placed in each anchor rod hole, the anchor rod steel strand is perpendicular to the bearing stratum, and the anchor rod steel strand and each anchor rod hole are concentric. And then prefabricated grouting materials are injected into all the anchor rod holes, after the grouting materials are solidified and meet the preset strength requirement, anchor rod steel strands are fixed into the prefabricated supports in a penetrating mode and are tensioned and locked, and finally target hanging bars are arranged in the prefabricated supports in a penetrating mode. And binding and fixing the target hanging bar and a bottom plate reinforcing steel bar of the bearing stratum. Due to the fact that reserved hole channels in the construction process are reduced through the construction method, the later underground water leakage hidden danger can be reduced, compared with an existing sleeve construction method, the service life of the anchor rod can be better prolonged, and the later tensioning force of the anchor rod is improved.
本发明实施例提供了一种抗浮锚杆及其施工方法，先垂直于承力地层开设多个锚杆孔，并在每个锚杆孔的上端部预埋护管，接着，将预制的锚杆钢绞线置入每个锚杆孔中，锚杆钢绞线垂直于承力地层，且锚杆钢绞线与每个锚杆孔同圆心。之后向每个锚杆孔中注入预制的注浆材料，并在注浆材料凝固且满足预设强度要求后，将锚杆钢绞线穿设固定于预制支座中并对锚杆钢绞线进行张拉锁定，最后将目标吊筋穿设于预制支座内，并将目标吊筋与承力地层的底板钢筋进行绑扎固定。由于上述施工方法减少了施工过程中的预留孔道，可以减少后期地下水渗漏隐患，比现有的套管施工方法更能提高锚杆的使用寿命，提高锚杆后期的张拉力。
