The invention belongs to the technical field of ironmaking, and particularly relates to a method for controlling the influence of an ore distribution sequence on the air permeability of a material bed under a high pellet proportion, which comprises the following steps: step S100, detecting the air permeability of a furnace charge structure of ore and coke with different ore distribution sequences under a reducing atmosphere of 500-1600 DEG C, the reducing atmosphere comprising, by volume percentage, 0-100% of CO, 0-100% of H2 and 0-99% of N2; and S200, optimizing the material distribution sequence according to a detection result. The method aims at improving the material distribution sequence of the ore, optimizing reasonable distribution of the ore in the blast furnace, developing air flow in the center and the edge, and ensuring long-term stable and smooth operation of the blast furnace. The method disclosed by the invention is applied to the production practice of the blast furnace, and is beneficial to refining operation of the furnace charge, optimizing the material distribution sequence, reducing the upward movement resistance of the gas flow, improving the gas permeability of the furnace charge, strengthening the smelting level of the blast furnace and improving the operation stability of the blast furnace.

The utility model discloses a bank protection reinforcing device for water and soil conservation, which relates to the technical field of bank protection and comprises a reinforcing brick, a planting part is arranged on the reinforcing brick, a first lining edge is arranged at the upper end of the inner wall of the planting part, a frame is lapped on the first lining edge, a grid is laid on the frame, and an irrigation part is arranged at the front end of the reinforcing brick.
