【 摘 要 】

In this paper, the construction technology of new cast-in-situ phosphogypsum wall is studied through pouring tests of different wall types, and the pouring operability, accuracy and efficiency of the new wall is evaluated. The results show the surface smoothness and vertical deviation of cast-in-situ phosphogypsum wall are determined to be 3-4mm. The construction efficiency of cast-in-situ phosphogypsum wall is about 6-7m2/h, which realizes high-precision and high-efficiency construction of wall. The technology of cast-in-situ phosphogypsum wall provides an effective method for the resource utilization of industrial solid waste and the large-scale innovation of wall materials.
