Preparation method of water-permeable ecological brick and water-permeable ecological brick
The invention discloses a preparation method of a water-permeable ecological brick. Sludge is pretreated, smashed and screened to obtain three kinds of sludge with different particle sizes (first sludge with a small particle size, second sludge with a medium particle size and third sludge with a large particle size), and then household garbage incineration ash and the three kinds of sludge with different particle sizes are mixed and stirred respectively. The three different mixtures (the first mixture, the second mixture and the third mixture) are obtained and laid in different structural layers of the permeable ecological brick, the sludge with the small particle size is laid on the bottom layer, the sludge with the medium particle size is laid on the middle layer, and the sludge with the large particle size is laid on the surface layer; the binder and the reinforcer are added between the layers, so that in the vibrating process, the binder and the reinforcer can infiltrate into particle size gaps under the action of gravity, and the strength of the water-permeable ecological brick is enhanced. Finally, integrally forming after pressing, curing and curing to obtain the water-permeable ecological brick with good water permeability and high strength.
本发明公开了一种透水生态砖的制备方法。通过将污泥进行预处理，粉碎筛分，得到三种不同粒径大小的污泥(较小粒径的第一污泥、中等粒径的第二污泥和较大粒径的第三污泥)，再以生活垃圾焚烧灰渣分别与三种不同粒径的污泥混合搅拌，得到三种不同的混合料(第一混合料、第二混合料和第三混合料)，并将三种混合料铺设在透水生态砖的不同结构层中，较小粒径的污泥铺设在底层，中等粒径的污泥铺设在中层，较大粒径的污泥铺设在表层，且在层与层之间加入粘结剂和强化剂，在振捣的过程中，粘结剂和强化剂可以通过重力作用下渗到粒径空隙中，增强了透水生态砖的强度。最后通过压制、固化、养护后一体成型，得到兼具透水性好且强度高的透水生态砖。
