Background technology
At present, the pavior brick that conventional street crossing spreads, generally by cement production systD, does not have permeable function, it is easy to cause seeping phenomenon.
In order to allow pavior brick obtain permeable performance, some pavior brick adopts the structure arranging vertical through hole on its face, and such water can flow downwardly into sewer from hole.But problematically, the use time one of this kind of pavior brick is long, its through hole still can be blocked by dirt so that water permeability lost efficacy, and causes surface gathered water problem.
In recent years, a kind of product being referred to as water-permeable brick is used more and more, and is laid on pavement.Water-permeable brick can solve surface gathered water problem, and during use, rainwater can run through water-permeable brick and permeate the ground, and supplements the soil water and subsoil water.
In actual applications, the permeable gap of conventional water-permeable brick is very easily blocked by foreign material such as muddy water, oils and fats that granule is less, even if being periodically subject to clean, it is prevented that pore plugging, it is also difficult to thoroughly clean out.When permeable gap is blocked, its water permeability declines very fast, and permeable effect is difficult to reach the desirable of design.
Water-permeable brick on domestic market mainly includes sintered ceramic water-permeable brick, concrete permeable brick, resin-bonded husky base water-permeable brick.In these water-permeable bricks, sintered ceramic water-permeable brick smooth surface, intensity are high, permeable respond well, but shortcoming to be gap relatively larger, it is easy to blocked by dirt and cause that water permeability lost efficacy, it addition, the manufacturing process of this type of water-permeable brick needs to consume mass energy and valuable clay resource;Concrete permeable brick is with low cost, molding is simple, permeation rate is better, but shortcoming is also easily blocked by dirt.On the other hand, although resin-bonded sand base water-permeable brick surface aesthetic, good water permeability, anti-skidding, comprcssive strength can be adjusted according to user's real needs, and water-retaining property is better, but shortcoming is easy ageing failure in the sun, it is necessary to again changes, causes that cost uprises.
