Finish-rolled deformed steel bar prestress anti-floating anchor rod and construction method thereof
The invention relates to a finish-rolled deformed steel bar prestress anti-floating anchor rod and a construction method thereof, and relates to the field of anti-floating anchor rods. The finish-rolled deformed steel bar prestress anti-floating anchor rod comprises a finish-rolled deformed steel bar rod body, an anchor rod hole formed in a soil body or a rock body and a concrete cushion layer located on the surface of the soil body or the rock body; part of the finish-rolled deformed steel bar rod body is arranged in the anchor rod hole in a penetrating mode; the anchor rod hole is filled with a first grouting material layer; the upper surface of the concrete cushion layer abuts against an anchoring support used for loading prestress; a cavity is formed in the anchoring support; the cavity is filled with a second grouting material layer; the end, protruding out of the anchor rod hole, of the finish-rolled deformed steel bar rod body sequentially penetrates through the concrete cushion layer and the anchoring support; and the finish-rolled deformed steel bar rod body is provided with a locking piece used for limiting downward sliding of the finish-rolled deformed steel bar rod body. The finish-rolled deformed steel bar prestress anti-floating anchor rod has the effect of improving the stability of the anti-floating anchor rod, additional settlement generated by the surrounding stratum can be reduced, the risk that the anti-floating anchor rod cracks is reduced, the durability of the anti-floating anchor rod can be improved, and the anti-floating effect is consolidated.
本申请涉及一种精轧螺纹钢预应力抗浮锚杆及其施工方法，涉及抗浮锚杆的领域，其包括精轧螺纹钢杆体、开设于土体或岩体内的锚杆孔和位于土体或岩体表面的混凝土垫层，部分精轧螺纹钢杆体穿设于锚杆孔内，锚杆孔内填充有第一灌浆料层，混凝土垫层的上表面抵接有用于加载预应力的锚固支架，且锚固支架内部设置有空腔，空腔填充有第二灌浆料层，精轧螺纹钢杆体突出于锚杆孔的一端依次贯穿于混凝土垫层与锚固支架，精轧螺纹钢杆体设置有用于限制精轧螺纹钢杆体向下滑移的锁紧件。本申请具有提升抗浮锚杆稳固性的效果，可以减少周边地层产生的附加沉降，降低抗浮锚杆产生裂缝的风险，有利于提高抗浮锚杆的耐久性，并巩固抗浮效果。
