摘要： Disclosed is a gridded cemented riprap scour-protection structure, including: riprap particles, uniformly distributed around the periphery of a building structure; and a gelling substance, filled between some riprap particles for connecting the stone particles into a whole from top to bottom to form cemented stalagmites; wherein a plurality of the cemented stalagmites are formed around the building structure in a gridded distribution, and each cemented stalagmite has a structure with a smaller top and a larger bottom. The present invention overcomes the defect of a poor scour-protection effect of the existing protective measures, thereby providing a gridded cemented riprap scour-protection structure with a stronger scour-protection ability formed at the peripheries of offshore building structures; and the scour-protection structure can also reduce the thickness and range of riprap around the offshore building structures, thereby reducing the comprehensive cost of anti-scouring protection.
