High-pulling-resistance pressure type anti-floating anchor rod and construction method thereof
A high-pulling-resistance pressure type anti-floating anchor rod comprises a steel sleeve, a prefabricated reinforced concrete conical tip arranged at the bottom of the steel sleeve and at least one reinforcing steel bar arranged in the steel sleeve, an internal thread sleeve is arranged in the conical tip, and the reinforcing steel bar is matched with the internal thread sleeve through external threads arranged at the bottom of the reinforcing steel bar so that the reinforcing steel bar and the conical tip can be fixed. The steel bars are coated with anti-corrosion grease and sleeved with PE corrugated protective sleeves, the length of the steel bars is larger than that of the protective sleeves, and the length of the steel sleeves is larger than that of the steel bars. The parts, extending out of the PE corrugated protective casing pipe, of the tops of the steel bars are bent and anchored in a building foundation slab; the construction method of the pressure type anti-floating anchor rod comprises the five steps of preparation before construction, steel sleeve driving, concrete pouring, pipe pulling through vibration and steel bar bending and fixing, the steel sleeve squeezes soil to form holes, so that the pulling resistance of the anchor rod is effectively improved, and the pressure type anchor rod enables an anchoring body to bear pressure stress, so that the anchoring body does not generate cracks, and the corrosion resistance is good.
一种高抗拔力压力型抗浮锚杆，包括钢套管、设置在钢套管底部的预制钢筋混凝土锥尖以及至少一根设置在钢套管内的钢筋,锥尖内设置有内螺纹套管，钢筋通过底部设置有外螺纹与内螺纹套管配合从而将钢筋和锥尖进行固定，钢筋上涂有防腐油脂且外部还套设有PE波纹护套管，钢筋的长度大于护套管的长度，钢套管的长度大于钢筋的长度；钢筋顶部伸出PE波纹护套管的部分弯折锚固于建筑物基础底板内；该压力型抗浮锚杆的施工方法包括进行施工前准备、钢套管打设、浇筑混凝土、振动拔管、钢筋弯折固定五个步骤，钢套管挤土成孔有效提高了锚杆的抗拔力，该压力型锚杆使锚固体承受压应力，从而使锚固体不产生裂缝，抗腐蚀性好。
