In pervious concrete, a flowing slurry is formed by strictly controlling the proportion of water and a cementing material, a proper coating is formed around coarse aggregate particles, and a highly permeable and interconnected pore system is formed, so that rapid drainage is realized. Research has shown that pervious concrete pavements are a unique and effective way to meet the ever-increasing environmental demands. Compared with the common concrete pavement, the pervious concrete pavement can absorb rainwater to enable the rainwater to permeate into the ground, is beneficial to protecting and supplementing underground water, reduces rainwater runoff, prevents the phenomena of surface water accumulation and skidding, supplements the underground water and underground aquifer, and supports sustainable construction. However, the permeability of the aggregate determines the water permeability of the pervious concrete, the existing pervious concrete aggregate mostly adopts common stones, the particle size of the stones mostly adopts single-particle grade or discontinuous-particle grade, the water permeability of the stones is poor, the water permeability function mainly depends on the gaps of the stone aggregates for water permeability, the porosity of the common pervious concrete aggregate is 15-25%, the water permeability is about 3.0mm/s, the requirement of timely drainage of urban waterlogging caused by urban continuous rainfall cannot be met, and the concrete aggregate is a big problem which needs to be solved at present. The existing common pervious concrete aggregate is common stone, the particle size of the stone is mostly single-particle grade or discontinuous-particle grade, the water permeability of the stone is poor, and the bonding property of the stone with a cementing material is inferior to that of a coral aggregate. The permeable function of the common concrete mainly depends on the gaps among the stone aggregates for permeable, while the permeable concrete with the coral aggregates can not only permeate water by utilizing the gaps among the aggregates, but also permeate water by utilizing the coral aggregates.
The invention content is as follows:
the technical problem is as follows: the invention aims to overcome the defects in the prior art and provides a preparation and construction method of porous coral aggregate permeable purification concrete, so as to solve the problem that the water permeability of the traditional permeable concrete cannot meet the requirement of rapid drainage of a large amount of urban inland inundation.

b. mixing coral sand, coral micro-sand, wood dust, cement, mineral powder, micro-dust beads and water in a horizontal mixer according to a mass ratio to prepare high-water-permeability coral mortar;
c. mixing the coral coarse aggregate with the high-permeability coral mortar according to the mass ratio of 2.5:1 to prepare the porous coral aggregate pervious concrete, and maintaining for 28 days at the temperature of 20 ℃ and the humidity of more than 95%.

The particle size of the coral coarse aggregate is 5-20mm, the barrel pressure intensity is not lower than 2.5MPa, the porosity is not lower than 40%, and the water absorption rate in one hour is not lower than 10%.
The wood chips are prepared under the wet condition, and the density of the wood chips is 0.6g/cm3。
The particle size of the coral micro-sand is 0-0.3mm, and the water absorption rate is not lower than 10%.
The cement is P.O 52.5.5R cement, the grade of mineral powder is S105, the grain diameter is 325 meshes, the grade of dust particle is first grade, and the grain diameter is 525 meshes.
The particle size of the coral sand is 0.3-4.75 mm.
A construction method of porous coral aggregate permeable concrete comprises the following steps: firstly, laying a lower layer of geotextile on an underlayer, then laying a gravel layer and an upper layer of geotextile, and finally laying a coral aggregate permeable concrete layer obtained by the preparation method of the porous coral aggregate permeable concrete as claimed in claim 1 on the upper layer of geotextile.
Has the advantages that: the coral coarse aggregate, the coral sand and the coral micro-sand have the characteristic of porosity, so the permeability of the coral sand and the coral micro-sand is far higher than that of common river sand. Utilize coral sand to replace ordinary river sand, replace cement with some coral sand to increase the permeability of coral mortar, it is lower to the influence of intensity, and the coral sand still has the interior maintenance effect that absorbs water, and at cement mortar stirring in-process, the coral sand absorbs water, makes its local water cement ratio with the cement contact surface reduce, thereby has improved the adhesive property at interface, has increased the bulk strength of pervious concrete. The high adsorptivity of the wood chips enables the wood chips to show higher water retention and gas filtering capacity, the wood chips also have high adsorptivity to heavy metal ions, and the skid resistance of cement mortar can be improved, so that the use requirement of roads is met. The coral aggregate permeable concrete can be used for permeable by utilizing the aggregate gaps and the coral aggregate can be used for permeable. Compared with the prior art, the main advantages are that:
(1) the coral aggregate concrete has high water permeability, the porosity of the coral aggregate is 45-65%, and the water permeability is more than 5.0mm/s, so that the requirement of rapid drainage can be met.
(2) Coral bones are adopted as aggregates, and are usually cleaned in the process of dredging a channel, so that the yield of the coral bones in southeast cities and islands in the south China sea is high, and the coral bones are favorable for recycling waste resources.
(3) Improves the water retention and the gas filtering capacity and plays a positive role in water and soil conservation.
(4) Has the function of purifying sewage and can adsorb heavy metal ions in water.
(5) The aggregate and the mortar have high porosity, so that the sound insulation and absorption effects are achieved.
(6) The addition of the wood chips improves the skid resistance and prevents pedestrians from falling down.
(7) The reasonable proportion of the mineral admixture improves the wear resistance and meets the requirement of the wear resistance of roads.
(8) The common aggregate pervious concrete adopts a cement mortar sand-coating method: 1) all the coarse aggregate and water are put into a stirrer to be stirred; 2) adding a cementing material and sand, and fully stirring; 3) and (5) discharging the concrete. The feeding method adopted by the invention comprises the following steps: 1) firstly, putting coral sand, coral micro-sand, wood chips, cement, mineral powder, micro-dust beads and water into a stirrer for stirring; 2) placing coral aggregates; 3) and (5) discharging the concrete. The feeding method can fully and uniformly mix the cementing material, the coral sand and the wood dust, and avoids the phenomena that the cementing material is attached to the aggregate to form a dry and hard block body because the aggregate absorbs water, the stirring is insufficient, the coral sand and the wood dust are not uniformly dispersed and the like because the aggregate is put in rough.
