specific Embodiment approach

[0074] Further, as a specific embodiment of the concrete structure reinforcement method provided by the present invention, the concrete protective coating is applied at least twice, specifically:

[0075] The two adjacent painting directions are vertical, and there are no defects such as missing coating, missing brushing, sagging, wrinkles, bubbling, and exposed base.

[0076] Furthermore, as a specific embodiment of the concrete structure reinforcement method provided by the present invention, the concrete protective coating is a flexible cement protective coating.

[0077] Flexible cement protective coating is a new type of concrete protective material that has both the flexibility of polymer materials and the durability of inorganic materials. At the same time, its flexible, crack-resistant and weather-resistant protective layer is also a coating that prevents the penetration of anti-corrosion liquid, which protects the concrete and improves the service life of the concrete...

Abstract

The invention provides a concrete structure reinforcement method, comprising the steps of: grinding the concrete base surface; grinding the exposed steel bars, and brushing the rust inhibitor on the surface of the steel bars; removing the loose part of the base surface, and brushing the bottom layer interface on the base surface Treatment agent; when the interface treatment agent is not dry, apply the top facade repair mortar on the damaged part until the original concrete base contour is restored; when the top facade repair mortar is not dry, paint the concrete protective paint on the entire base surface. The concrete structure reinforcement method provided by the present invention can completely isolate the exposed steel bars from moisture and air by applying a rust inhibitor, preventing oxidation and corrosion again and affecting the strength of the steel bars; by applying an interface treatment agent, the repair mortar can be strengthened At the same time, it can prevent the corrosion of the steel bar and the base surface; by applying the concrete protective coating, the strength of the repaired base surface can be effectively improved, and the combination with the repair mortar can effectively improve the strength of the repaired part.

Description

technical field [0001] The invention belongs to the technical field of electric power construction, and more specifically relates to a method for reinforcing concrete structures. Background technique [0002] The power system is the main component of lifeline engineering, and its importance is self-evident. The substation plays the role of voltage transformation and shunting in the power system, and is an important node of the entire power transmission and distribution network, while the substation structure plays the role of supporting power equipment and bearing the tension of the wires, so the research on the substation structure has its practical significance . [0003] In the early construction of substations in my country, the internal structure and support of the substation mostly adopt the form of reinforced concrete ring rod structure. However, with the increase of the operating time of old towers and the commissioning and operation of new towers, especially high-...
