Abstract: Nowadays, my country's economic development is getting faster and faster, which leads to higher and higher requirements for infrastructure construction in my country, which in turn leads to more and more water conservancy construction projects, but the requirements for water conservancy construction projects are also increasing. The higher it is, the stricter the requirements for the construction technology of roller compacted concrete in water conservancy construction. In order to be able to improve the economic benefits of water conservancy construction on the basis of improving the quality of water conservancy projects, it is especially necessary to put forward strict requirements on the construction of roller compacted concrete in water conservancy project construction. This article mainly discusses the construction process of roller compacted concrete in water conservancy projects in detail, analyzes the construction process and main points of roller compacted concrete, and proposes corresponding solutions according to different needs.
