Modern civilization makes current discharge in order, rainwater etc. is all discharged into the position of artificial regulation by all kinds of concrete floors, concrete road, asphalt roads, pumping equipment etc., but, people are when enjoying modern civilization, really ignore the natural law, ignore rainwater and go back to nature problem.
Soil erosion, refers not only to the soil body under rain drop erosion and runs off, also include the loss of water；The expenditure of the Nature is in a basic balance with income, after the surface water is evaporated by the sun, by rain compensation, moisten the earth, and modern civilization causes many places, ground and is hardened (such as road, ground, square etc.), these ground being hardened, under the sun tans by the sun, ground moisture is gone out by evaporation, when raining, rainwater flows away on the ground being hardened, and returns less than underground so that underground water source can not get supplementing.
The irradiation of the sun, while giving the earth warm, moisture is evaporated to sky, then pass through sleet cloud and mist and again moisture is issued moist soil, now due to the existence of all kinds of concrete floors, concrete road, asphalt roads, pumping equipment etc., moisture goes out to go, and but returns and does not come, has had a strong impact on soil tilth.
Rain water collecting system, it is simply that after rainwater is collected according to demand, and after the rainwater collected is processed, reach to meet the system of design use standard.
China is carrying out new " Four Modernizations " and is building, and wherein, urbanization and agricultural modernization are desirable that attention preserving soil moisture problem.
Rainwater is collected, it is important that aspect, be solve xoncrete structure permeable problem.Existing armored concrete can bear suitable load, this be fact proved by countless, but owing to armored concrete is waterproof, just making permeable reinforced concrete container for us or permeable bar-reinforced concrete member brings difficulty, the present invention can solve this difficulty.
Summary of the invention
The concrete scheme that this invention address that is:
Pervious concrete is combined formation by permeable armored concrete with anticorrosion reinforcing bar；The pervious concrete met design requirement by the reinforcement of concrete in ordinary reinforced concrete substitutes, and is substituted by the anticorrosion reinforcing bar through special handling of the reinforcing bar in ordinary reinforced concrete, so that it may make permeable armored concrete.
Described pervious concrete is to make cementitious matter with cement, and with the relatively uniform coarse aggregate of particle diameter as aggregate, without the concrete that fine aggregate produces, concrete strength must is fulfilled for designing requirement.
Cementitious matter made by selected cement, and cementitious matter made by preferential recommendation ordinary cement；Cement consumption is determined by Mix Ratio Test.
The coarse aggregate of pervious concrete made by the aggregate of preferential recommendation particle diameter 10-20 millimeter, specifically determines depending on concrete thickness, if concrete thickness is more than 100 millimeters, then recommends the coarse aggregate adopting the aggregate of particle diameter 20-40 millimeter to make pervious concrete；Aggregate consumption is determined by Mix Ratio Test.
Also should use additive, admixture in pervious concrete according to different requirement of engineering, specifically be determined by Mix Ratio Test.
Described anticorrosion reinforcing bar is the reinforcing bar that covers with the anti-corrosion material of particular/special requirement after rebar surface rust cleaning, cover will tightly, bonding should be firm；Rebar surface rust cleaning is not require nothing more than the block rust of removing, also should remove bar list edema over the face rust；Preferential recommendation but be not limited only to reinforcing bar rust cleaning after, at bar list topcoating epoxy resin, then table wrap up in non-woven fibre cloth formed rebar surface anticorrosive coat；Further, preferential recommendation but be not limited only to the proportioning of epoxy resin according to: phenolic resin 100, ethanol 0-5, NL6-10, firming agent 120-200 prepare.
Described pervious concrete and anticorrosion reinforcing bar must possess suitable withdrawal resistance, refer to guarantee the withdrawal resistance of the requirement of the common stress of armored concrete.
The described cement mortar in pervious concrete is unsuitable to be too much that requirement can make aggregate fully bonding, is unlikely to the concrete mix having superfluous water mud, and cement mortar is too much, affects water penetration.
The maintenance of described pervious concrete, is that pervious concrete surface area is big, it is easy to make moisture content distribute, therefore should water conservation, again frequent wet water.
Permeable armored concrete provided by the invention, it is possible to solve there is the occasion that in the Structural Engineering of particular/special requirement, reinforced concrete structure is had water penetration requirement, there is originality, economy and novelty.
