Background technology
" sponge urban construction technical manual low impact exploitation storm-water system builds (try) " that China promulgates house town and country construction portion in October, 2014 is pointed out: " water-permeable brick is mated formation and water-permeable cement concrete is mated formation is primarily adapted for use in square, parking lot, footpath and vehicle flowrate and the less road of load; such as building and community road, the bicycle lane etc. of town road ... .. ".The pluses and minuses that water-permeable brick is mated formation include: " permeable pavement suitable application region is wide, easy construction, can recharge of groundwater there is certain peak flow cut down and rainwater purification effect, but easily block, cold district has by the risk of freeze-thaw damage.”
Existing water-permeable brick, plate are mainly pervious concrete and permeable mortar product.Binder Materials is cement (silicate or sulphate aluminium cement) or resin (epoxy, polyurethane, acrylic resin etc.), with unsaturated consumption or thin layer Binder Materials slurry parcel form graded sand, stone aggregate, form a certain proportion of hole while aggregate is bonded as entirety, become the water-permeable passage of brick or plate.This that be randomly formed, random, tortuous water-permeable passage, easily blocked by dust, earth, vegetation chip etc. naturally using in environment, water permeable ability may be caused to be greatly lowered, need often and in time to use flushing, negative pressure-pumping mode to clear up, time-consuming, effect is the most undesirable.In the north, when there is sleet in winter, this kind of water-permeable brick, plate are often freezed at permeable hole saturation state, and frost-heaving force can damage the globality of brick or plate, experience multiple freeze-thaw cycle and brick or plate may be made to occur that peeling is even collapsed.Additionally, differential settlement often occurs in the basic unit of permeable pavement, water-permeable brick or plate can be made to be in and to be easily snapped off by curved state, big brick or plate.Resin base water-permeable brick or the cementing material epoxy resin of plate, polyurethane resin, acrylic resin etc., irradiated by sunlight and high temperature (more than 35 DEG C) effect is the most aging, it is difficult to meets the durability (30~100 years) of foundation engineering construction requirements.
For existing water-permeable brick, the disadvantages mentioned above of plate, this utility model conversion thinking, in terms of selecting suitable material and changing permeable mode two, solve the problems referred to above comprehensively.
The durable durable solution of porous disc
The suitable material selected has two kinds, the highest ductility cement-base composite material (HDCC or ECC) and ultra-high performance concrete (UHPC).Both materials are short fiber reinforced, toughness reinforcing toughness cement-base composite material, make permeable groove, the porous disc in hole realizes high bending resistance or flexural capacity.HDCC possesses good freeze thawing resistance and anti-wear performance, and UHPC is not the most by freeze thawing infringement and has super-high wear-resistant performance.In natural environment and under regular service conditions, it is contemplated that the durability of HDCC and UHPC is able to more than 50 years and 100 years.Therefore, use both materials can produce durable durable porous disc, solve frangibility, not freeze thawing resistance, the problem such as the most wear-resisting, the most weather-proof.So far, HDCC and UHPC material has obtained many application, but not yet for porous disc manufacture.
