Experimental Study on Riprap Revetment Treatment Project of Silt River
The model analysis and process simulation of riprap revetment treatment are carried out on the process and effect of the silt river drainage and rehabilitation project located in Xiangfu District and Qi County,Kaifeng City.The results show that riprap is an ideal revetment material with strong adaptability to riverbed deformation.The construction effect of riprap revetment is mainly related to the particle size of rubble,the quantity of use and the coverage rate of bank slope.The effect of bank protection of uneven spreading of three layers of small stone material is obviously better than that of uneven spreading of block stone.For the river reach with large water depth and fast flow velocity,the throwing construction is strictly in accordance with the design requirements,while for the river section with small water depth and slow flow rate,it is necessary to strengthen the throwing process control so as to avoid the accumulation of rubble affecting the effect of bank protection.
