The invention discloses an auxiliary laying device and method for a concrete slope protection plate for channel construction, and relates to the auxiliary laying device and method for the concrete slope protection plate. The problems that the labor intensity of workers is high and the safety risk is large in the channel protection building construction process are solved. On the premise that the laying quality of the concrete slope protection plate is guaranteed, damage to a slope surface sand cushion layer is reduced, safety of workers in the slope surface construction process is improved, and potential safety hazards such as slipping, falling injury, clamping injury and bumping of the workers in the construction process are reduced; and the hoisting unit greatly reduces the labor intensity of manual carrying while ensuring the safety. When the slope surface of the channel is laid, an included angle beta is formed between the crossing truss and the axis of the channel, a worker lays the concrete slope protection plate in the direction from the channel bottom to the channel top, and the problem that butt joint cannot be achieved due to staggered stubbles in a segmented construction method is solved; and meanwhile, the problem that butt joints are filled through cast-in-place or precast slab cutting is avoided. The invention belongs to the technical field of concrete slope protection plate laying.

This invention relates to the field of farmland irrigation engineering technology, and discloses a prefabricated channel made from retired wind turbine blades and its construction method. The prefabricated channel consists of a rectangular channel body composed of a base plate unit and side plate units, innovatively employing a double connection structure. A rectangular mortise at the top of the side of the base plate unit connects to a rectangular tenon at the bottom of the side plate unit via sliding assembly, forming a non-detachable connection. The base plate unit has L-shaped stepped grooves and inverted L-shaped stepped grooves at both ends, while the side plate units have square socket plugs and square socket slots at both ends, enabling the splicing of adjacent channel bodies. A high-density polyethylene geomembrane impermeable layer and an impermeable lining concrete layer are sequentially laid on the inner surface of the channel body to form a composite impermeable structure. This invention effectively solves the problem of resource utilization of solid waste from retired wind turbine blades, transforming it into a channel component with practical value. This not only reduces channel construction costs and significantly improves construction efficiency (achieving rapid assembly and eliminating the need for on-site pouring), but also ensures the integrity and stability of the channel structure, resulting in significant environmental and economic benefits.
