CONSTRUCTION METHOD FOR EROSION AND WEAR RESISTANT PROTECTIVE COATING FOR STRUCTURE AGAINST HIGH VELOCITY WATER FLOW

摘要

A construction method for an erosion and wear resistant protective coating for a structure against a high velocity water flow, comprising the steps of construction preparation, base surface grinding and cleaning, washing, protective layer construction, maintenance, etc. Erosion resistance is realized using polyurea instead of traditional high strength erosion and wear resistance concrete or epoxy resin, and since polyurea has excellent physical and mechanical properties and has the advantages of high tensile strength, a large extent of deformation, high wear resistance, high adaptability and being easy to construct. The problem of the wear of a flow channel caused by high velocity water flow can be better solved.
