Sewage interception water-permeable brick

Abstract

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.

Description

technical field

[0001] The invention relates to a water-permeable brick, in particular to a water-permeable brick with sewage interception ability. Background technique

[0002] Permeable bricks are designed to solve urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance. They have the characteristics of maintaining water permeability, moisture retention, non-slip, cold resistance, weather resistance, noise reduction, and sound absorption. Use on sidewalks. According to the statistics of Tokyo, Japan in 1996, it can be known that the rainwater outflow rate in areas where permeable bricks are laid has dropped from 51.8% to 5.4%. Therefore, permeable bricks are the primary material for capturing urban rainfall and replenishing groundwater. Traditional permeable bricks mainly use slag waste and waste ceramics as raw materials, and are formed by pressing or sintering. There are mainly three types of concrete-bonded or st...

Examples

Embodiment 1

[0038] 1. Purchase the pearl cotton cover 21, the grass planting brick 1 and the non-woven bag body 22;

[0039] 2. Weigh its particle size as 0.5-20cm 2 Seashore aged shells, its particle diameter is the synthetic magnesite of 0.1-2mm (this synthetic magnesite is the general material of porous magnesium carbonate hard block fragmentation), its particle diameter is the sulfonated coal filter material of 2-4mm, and Magnesium oxychloride cement, wherein: the total weight of filtrate is 100 parts, seashore aged shells are 40 parts, synthetic magnesite is 25 parts, sulfonated coal filter material is 25 parts, magnesium oxychloride cement is 10 parts, After preparing the materials, they are mixed together to obtain the mixture;

[0040] 3. Fix 22 sets of non-woven bags in the honeycomb plate mold hole of the shaker, then add the mixture in step 2 into the non-woven bag, and vibrate horizontally while gradually feeding, and intermittently The mixture in the non-woven bag body is p...

Embodiment 2

[0046] 1. Purchase the pearl cotton cover 21, the grass planting brick 1 and the non-woven bag body 22;

[0047] 2. Weigh its area as 3-15cm 2 Broken thin ceramic bricks, broken slag with a particle size of 0.1-2mm and high calcium and magnesium content (the slag itself contains a large amount of unburned carbon, so there is no need to add activated carbon filter material), sodium hexametaphosphate and bentonite, Wherein: the total weight of filtrate is 100 parts, the broken thin pottery brick is 60 parts, the slag is 30 parts, sodium hexametaphosphate is 5 parts, and bentonite is 5 parts, and they are mixed together after preparing the materials to obtain the mixture;

[0048] 3. Fix 22 sets of non-woven bags in the honeycomb plate mold hole of the shaker, then add the mixture in step 2 into the non-woven bag, and vibrate horizontally while gradually feeding, and intermittently The mixture in the non-woven bag is pressed downward by the elastic body, and the non-woven bag wi...
