Abstract

The invention discloses an electrochemical repair device for concrete salt damage destruction. The electrochemical repair device comprises an accommodating box mechanism circumferentially wrapped withconcrete, the upper end of the accommodating box mechanism is open, the accommodating box mechanism contains an electrolyte, anode mechanisms are immersed in the electrolyte, the anode mechanisms aremutually insulated and isolated through spacing plates arranged in the accommodating box mechanism, the anode mechanisms are connected with a power source though anode connecting wires, the power source is connected with steel bars serving as a cathode in the concrete through cathode connecting wires, and a stirring mechanism and a temperature adjusting mechanism are further arranged in the electrolyte. The electrochemical repair device has the advantages that salt damage is repaired, sea water shock is avoided, and the structure is stable.

Description

technical field [0001] The invention relates to the field of repair and reinforcement of concrete structures in seaport engineering, in particular to an electrochemical repair device for concrete salt damage damage. Background technique [0002] Concrete structures have good performance and low cost, and are widely used in construction projects, especially harbor projects. But in fact, a large amount of chloride ions invade the interior of the concrete, which accelerates the corrosion of steel bars, material deterioration, and structural function reduction, so that a large number of concrete structures cannot reach the predetermined service life, and the loss of concrete structures due to insufficient durability Very huge. Concrete durability problems mainly include carbonation, salt damage erosion, freeze-thaw effect, alkali-aggregate reaction, etc., among which the damage caused by salt damage erosion is the most serious. Under salt corrosion, the steel bars inside the c...
