Mixed material for water-permeable baffle wall

Traditional retaining engineering use weep holes in walls. Once the weep holes are blocked, poor drainage causes water accumulation. The plasticity and the shear resistance of the soil mass of a slopeare sharply reduced under the action of water accumulation, and the weak surface of a soil layer forms a through sliding surface, and the slope is easily destabilized. Huge sliding force and head pressure act on a retaining wall and cause the collapse of the retaining wall. The safety coefficient is increased during project designing in order to solve the contradiction, so the section of the retaining engineering is increased, the masonry quantity is increased, and the cost is high. Waste residues produced during yellow phosphorus production are selected, and phosphorus slag powder, gypsum, lime and aggregates are added according to a certain ratio to form a new water-permeable mixed material. The mixed material has good gelling property and permeability. A wall adopting the mixed material allows water to permeat
