A single filter brick weighs about 10kg and is connected using a socket and sealing ring. For different project designs, the processed filter bricks do not require any adjustments on site. They can be quickly assembled using specialized tools, and the installation of filter bricks in the pool is as convenient as laying floor tiles in residential homes. Due to the height of the water and gas filter bricks being only about 0.3m, a significant reduction in the height of the civil engineering pool has been achieved; And there is no need for any embedded parts, filter beams, filter columns, etc. inside the pool body, making the structure of the pool body simple; When installing filter bricks, C30 concrete is first laid to level the bottom of the pool, and then filter bricks are laid. After the bottom concrete has initially solidified, C30 concrete needs to be poured into the gaps between adjacent filter bricks and the pool wall to make the entire air-water distribution system and the pool bottom a solid and durable whole. Due to the fact that the installation of filter bricks involves laying concrete at the bottom of the pool after the completion of civil engineering, the accuracy requirements for the civil engineering at the bottom of the pool are relatively low. Greatly reducing the cost of civil construction and the installation cost of water and gas distribution systems.
