Concrete hexagonal block laying and positioning device and concrete hexagonal block laying method

The invention relates to the technical field of dyke slope protection construction of water conservancy construction engineering, and provides a concrete hexagonal block laying and positioning device. The concrete hexagonal block laying and positioning device comprises three sets of limiting stoppers and a connecting beam, wherein each limiting stopper is of a cross-shaped structure formed by welding two horizontal beams and a seam control panel. The three sets of the limiting stoppers are connected through the connecting beam, so that the side surfaces of three seam control plates can abut against the three adjacent edges of a regular hexagon, the bottom surfaces of six horizontal beams are located on the same plane to form a laying control surface, and an adjustable level bubble used for adjusting the longitudinal gradient of the laying control surface is installed at the middle of the connecting beam. The invention further provides a concrete hexagonal block laying method by using the device. The concrete
