Abstract：In order to compare the influence of different cleaning schemes on the permeability performance of solid waste pervious concrete with different target porosity,this paper tested the cleaning effects of cleaning schemes such as washing pressure,washing angles,and cleaning method on the pores of solid waste pervious concrete with three different target porosity of 15％,20％,25％under different pressure values.The results show that when the water pressure is increased to 20 MPa,the pore clogging of the three kinds of solid waste permeable samples with target porosity can be recovered well.For the solid waste permeable specimen with target porosity of 15％,the cleaning effect when washing angle of 30° is appropriate.For solid waste permeable specimen with target porosity of 20％and 25％,the washing angle of 40°～60° is more suitable.The effect of the combined cleaning scheme is slightly better than that of high pressure flushing,but the effect is not obvious.The cleaning sequence has a significant impact on the recovery effect of permeability,and the pore recovery effect is better after 20 MPa high-pressure flushing and 0.05 MPa vacuum suction.
