Artificial self-mixing concrete anti-floating anchor rod
The invention relates to the technical field of concrete anti-floating anchor rods, in particular to an artificial self-mixing concrete anti-floating anchor rod which is characterized in that firstly, a drilling machine is used for drilling a hole in a crack of a basement bottom plate to the designed length, a dust suction pipe communicated with dust suction equipment is put down, lime and soil layer impurities in the hole wall are subjected to dust removal and cleaning, and cement and sand in the proportion of 1: 1 are adopted; the method comprises the following steps of: fully mixing dry mortar by using external stirring equipment, pouring the dry mortar into a hole through a grouting pipe, then adding a certain amount of water into the hole, inserting a vibrating bar with the length of 12 meters into the hole for fully compacting while controlling the water-cement ratio to be 5-8%, then implanting a steel bar into the hole, and vertically limiting through an external steel bar positioner, the reinforcing steel bars are located at the vertical central axis positions of the holes, 30% of 1 * 3 broken stones are additionally added, a vibrating bar with the length of 12 m is inserted into the holes again for secondary full compaction, part of the broken stones penetrate through the hole walls, and the friction force is greatly increased.
本发明涉及混凝土抗浮锚杆技术领域，尤其为一种人工自拌混凝土抗浮锚杆，本发明中首先，使用钻机在地下室底板裂缝处钻孔至设计长度，通过吸尘设备连通的吸尘管下放，对孔壁内的石灰、土层杂质进行除尘清洁，采用1:1比例的水泥与砂料，使用外部搅拌设备充分混合成干砂浆，并将其通过注浆管倾倒至孔内，接着向孔内添加一定量的水，利用长度为12米的振动棒插入孔内进行充分振实，同时控制水灰比在5%‑8%之间，紧接着，将钢筋植入孔内,可通过外部钢筋定位器进行竖向限位，使得钢筋位于孔的竖向中轴线位置，添加额外30%的1×3碎石，再次利用长度为12米的振动棒插入孔内进行二次充分振实，使部分碎石穿过孔壁，使得摩擦力大增。
