The invention discloses a construction method for ensuring the pulling resistance of a pulling-resistant screw, the pulling-resistant screw is fixed in a pre-buried square steel pipe through grouting, and the construction method comprises the following steps: S1, water left in the square steel pipe is pumped out; s2, measuring and setting out a grouting range control point, performing roughening treatment on a concrete surface in the grouting range, and performing rust removal and dust collection cleaning on the interior of the square steel pipe; s3, brushing an adhesion agent on the concrete surface around the square steel tube; s4, the tool performs preliminary positioning on the anti-pulling screw rod, and a high-precision measuring instrument is combined with a precision control network to perform verification adjustment and precise positioning on the anti-pulling screw rod; s5, a formwork is installed, and reinforcing steel bars and a reinforced net are laid; s6, grouting materials are poured, and maintenance is conducted; and S7, detecting the strength of the grouting material and the pulling resistance of the screw rod. The method has the advantages that the bond stress of the anti-pulling screw is improved, the influence on a concrete pulling cone body around the screw is small, and the later maintenance workload is small.
本发明公开了一种确保抗拔螺杆抗拔力的施工方法,抗拔螺杆通过灌浆固定在预埋的方钢管内,包括以下步骤:S1:抽除方钢管内残留的水;S2:测量放样出灌浆范围控制点,对灌浆范围内砼面进行凿毛处理,对方钢管的管内进行除锈、吸尘清理;S3:方钢管四周混凝土面刷界面剂;S4:工装对抗拔螺杆进行初步定位,并采用高精测量仪器结合精密控制网对其进行核验调整、精准定位;S5:安装模板、铺设钢筋,加筋网;S6:灌浆料灌注、养护;S7:灌浆料强度、螺杆抗拔力检测。具有提高抗拔螺杆握裹力、对螺杆周边混凝土拉椎体影响小、后期维修工作量小的优点。
