Description

technical field [0001] The invention relates to the field of hydraulic engineering construction, in particular to a nano-scale inorganic anti-corrosion, anti-seepage and anti-fouling coating structure for hydraulic concrete. Background technique [0002] With the comprehensive promotion of river, lake and reservoir projects, the increase of cross-basin water diversion projects, the forms of hydraulic buildings tend to be diversified. In water conservancy projects, single or several buildings with different functions and different types are often used to regulate water flow. , Prevent and control water damage to meet the needs of water resources, mainly including water delivery channels, water delivery pipelines, diversion tunnels, aqueducts, inverted siphons, culverts, etc. [0003] Hydraulic concrete is one of the most important materials in the construction of water conservancy projects. It needs to play a role under various complex environmental conditions and ensure the ...
