Traditional river slope protection construction uses manual construction on the slope protection, and various construction materials and prefabricated structures still rely on manual transportation from the bottom of the slope protection to each construction node on the slope protection surface. The material transportation efficiency is low, and the slope protection often needs to be sprayed and maintained after the construction is completed.

[0003] At present, in the actual use of the existing river bank protection paving construction device, although it can use the conveyor belt to transport construction materials and prefabricated structures, the greater the inclination angle of the river bank protection, the worse the anti-slip ability of transporting construction materials and prefabricated structures, resulting in poor material transportation stability and insufficient safety. Therefore, it is necessary to provide a river bank protection paving construction spray maintenance device for water conservancy projects to solve the above technical problems.
