In order to avoid urban waterlogging, the water permeable bricks are widely used in urban road reconstruction. The common permeable brick in the market is made of crushed stone and concrete by pressing. In addition, the brick that permeates water still has a lot of materials, can divide into: polymer fiber concrete water permeable bricks, color stone composite concrete water permeable bricks, color stone epoxy through body water permeable bricks, concrete water permeable bricks, cast dust-removal ash water permeable bricks and the like. The above water permeable bricks have more or less partial defects. The colored stone epoxy through body permeable brick needs to be glued with imported modified epoxy resin, so that the production cost is relatively high, and the colored stone epoxy through body permeable brick cannot be produced in large scale and popularized and used. The color stone composite concrete permeable brick is divided into a surface material layer and a base material layer, the pressing process is relatively complex, and the conditions of low strength of a joint, falling of the surface layer and the like can be caused by the two-time forming of the color stone composite concrete permeable brick. The price of the cement permeable brick is relatively low, but the strength is reduced with the sudden change of the temperature, and the performance is still to be improved.
