By optimizing ship and conveyer design,the shipborne ecological slope protection technology of wet spraying vegetation-compatible concrete can be further improved.The optimized specific parameters and the construction process are introduced in detail firstly.Then the technology was applied to Huama Lake Ⅱ water system connecting channel slope protection project in Ezhou City,Hubei province.Through engineering application,it is verified that the ship speed has been increased by 50％and the construction efficiency has been improved by 50％.One month after the completion of construction,none of the bolts,spray layers,or barbed wire were found to be broken off or damaged.And the erosion depth of the sprayed layer in the steep slope area and gentle slope area is 0.8 cm and 0.5 cm,with an average erosion amount of 7.26 kg/m2 and 6.05 kg/m2,which shows that the sprayed layer has good water and soil conservation ability.The plant coverage rate on the multi-level slope is more than 90％,and the average plant height is 8 cm～15 cm,in which the ryegrass plant was as high as 1 m.The improved shipborne ecological slope protection technology of wet spraying vegetation-compatible concrete has been verified with more advantages.
