In the construction of water conservancy projects, the pouring of concrete is the key to the construction of the project, especially for the projects with large scale, large strength, and tight construction period, its pouring work is very important. This paper discusses the evaluation model of concrete pouring construction quality based on support vector machine. In this paper, the concrete pouring technology is analyzed, and the evaluation method based on support vector machine is proposed. On this basis, the experimental study of concrete pouring construction quality is carried out. The experimental results of this paper show that the evaluation model based on support vector machine can well evaluate the quality of concrete pouring construction. Under the evaluation model of support vector machine, its average pouring strength and average utilization rate of cable crane are better than other evaluation models.
