Leak repairing method for reinforced concrete microcracks
The invention discloses a leak repairing method for reinforced concrete microcracks, which comprises the following steps: a drilling step: drilling a hole on the surface of to-be-repaired concrete with the microcracks until a reinforcing steel bar in the buried concrete is exposed, and defining the reinforcing steel bar as an exposed reinforcing steel bar; and a power connection step: taking the exposed reinforcing steel bar as a cathode, and installing an anode on the surface of the to-be-repaired concrete. And a grouting step, wherein repairing slurry is poured into the surface of the to-be-repaired concrete. And an electrifying step: turning on a power supply, enabling the anode and the cathode to conduct current through the repairing slurry, and gradually dehydrating the repairing slurry and repairing the microcracks on the surface of the concrete to be repaired along with the proceeding of the electrolytic reaction, the electrothermal reaction and the electroosmosis action. The repairing efficiency is high, and the repairing effect is good.
本发明公开了一种用于钢筋混凝土微裂纹的补漏方法，包括：钻孔步骤，在产生微裂纹的待修补混凝土的表面钻孔，直至掩埋的混凝土内的钢筋显露出来，定义其为显露钢筋。接电步骤：以显露钢筋处作为阴极，在待修补混凝土的表面安装阳极。注浆步骤：向待修补混凝土的表面灌注修补浆料。通电步骤：开启电源，使阳极和阴极通过修补浆料导通电流，随着电解反应、电热反应和电渗透作用的进行，使修补浆料逐渐脱水并修补带修补混凝土的表面的微裂纹。其修补效率较高，且修补效果良好。
