Problems solved by technology

Once serious corrosion damage occurs in the spray splash area of ​​the marine structure, the bearing capacity of the entire facility will be greatly reduced, the service life will be shortened, the structural safety will be affected, and the facility will even be scrapped in advance
[0004] Aiming at the durability of concrete structures, the current engineering generally adopts "prevention first" measures. The technologies used mainly include: concrete surface coating protection, chemical admixtures, mineral admixtures, etc., but the above technologies are mainly As a surface covering, its operation and construction are cumbersome, and once the protective coating on the surface is damaged, the corrosion resistance of the original concrete structure will be greatly reduced, and the corrosion of the concrete structure and even the concrete steel structure will be intensified, seriously affecting the performance of the concrete structure. Therefore, it is necessary to propose a self-corrosion-resistant concrete structure to solve the above-mentioned problems, so as to adapt to the harsh marine environment

Abstract

The invention provides multi-layer functional corrosion-resistant concrete. The multi-layer functional corrosion-resistant concrete comprises a core concrete structure, a core steel structure, connectors with steel sleeves, welded steel fabric and a surface layer concrete structure. The core steel structure is arranged inside the core concrete structure, the welded steel fabric is arranged inside the surface layer concrete structure, and the core steel structure is connected with the welded steel fabric through the connectors with the steel sleeves. The invention further relates to a mechanical connecting method of the multi-layer functional corrosion-resistant concrete. The core steel structure and the welded steel fabric structure on the surface layer are connected through the connectors, the steel sleeves and deformed steel bars. According to the invention, the requirement for the service strength of marine facilities can be met, the high corrosion resistance is achieved, and therefore oceanic building concrete can have the longer service life. The multi-layer functional corrosion-resistant concrete and the mechanical connecting method of the multi-layer functional corrosion-resistant concrete have the advantages of being high in practicability and functionality.

Description

technical field [0001] The invention relates to the field of marine structure concrete, in particular to a multilayer functional anti-corrosion concrete structure. Background technique [0002] With the global energy shortage, environmental pollution and other problems becoming more and more serious, in recent years, wind energy, as a non-polluting renewable energy, has been paid more and more attention by people, and its development is the fastest. However, due to the limited space available on land and better wind energy conditions at sea, offshore wind energy development has been increasingly valued. Offshore wind power has the characteristics of high wind speed, continuous and stable wind resources, and large power generation. [0003] In reality, due to the harsh marine environment where wind farms are located, the corrosion of marine structures is very serious, which brings many troubles to the subsequent operation and maintenance of wind farms. From the perspective o...
