Sewage interception water-permeable brick
The invention discloses a sewage interception water-permeable brick which comprises a brick body and filter pieces. The filter pieces comprise bags and filter objects located in the bags. The filter pieces comprise pearl wool sleeves, the non-woven bags and the filter objects located in the non-woven bags. An organic flocculant layer is arranged on the inner surface of each pearl wool sleeve. Each filter object is prepared from, by weight, 20-60 parts of flaky high-strength material, 20-50 parts of fine aggregate and 5-20 parts of binding agent, and the flaky high-strength material, the fine aggregate and the binding agent are mixed and compacted into a blocky structure. The flaky high-strength material is a mixture of one or two or more of long-laid shells, broken earthenware bricks and lamina schist, the fine aggregate is formed by mixing 5-50 parts of alkalescent porous minerals and 0-45 parts of carbonaceous filter materials by weight, and the binding agent is one of high-alumina cement, magnesium oxychloride cement, phosphate binding agent and hydration glass. The water-permeable brick has the beneficial effects that walking is facilitated, and heavy metal, toxic organic substances and colloid of water can be captured so as to avoid groundwater pollution.
