[0006] The seam control plates of the three groups of limiters are respectively provided with seam plate thickening bolt holes, through which bolts are passed to thicken the seam plates. Bolt holes fix the thickened plate and adjust the thickness of the seam control plate .
[0007] Optimization solution: The connecting beam comprises a main beam section, a first sub-beam section and a second sub-beam section. The first sub-beam section is welded to one end of the main beam section at an angle of 120°, and the second sub-beam section is welded to the other end of the main beam section at an angle of 120° or connected by a pipe. One end of the seam control plate of one set of limiters is welded to the main beam section of the connecting beam, and the ends of the seam control plates of the other two sets of limiters are respectively welded to the first sub-beam section and the second sub-beam section of the connecting beam.

[0014] Along the river bank, mark the slope position of the slope protection on the concrete paving surface in step 1, and use fishing lines to pull horizontal and vertical lines to control the laying of precast blocks.
[0015] Step 3: Mortar paving
[0016] The mortar is paved in layers along with the concrete hexagonal blocks. The mortar paving thickness is adjusted appropriately according to the actual thickness of the concrete hexagonal blocks. The concrete hexagonal blocks are laid after the mortar is slightly dry.
[0017] Step 4: Laying of concrete hexagonal blocks
[0018] Step 4.1: The concrete hexagonal blocks are laid layer by layer from bottom to top and from one end to the other. First, according to the masonry base line, appropriate amount of mortar is laid at the joint surface with the cast-in-place concrete panel for leveling.

During laying, place the concrete hexagonal block laying positioning device on the two concrete hexagonal blocks. The horizontal beam and seam control plate on the main beam section fit the top and side surfaces of the concrete hexagonal blocks. Adjust the adjustable level bubble according to the slope.

The mortar paving can be appropriately overthick, and then use a rubber hammer to hammer the concrete hexagonal blocks to squeeze them tightly and fit them with the horizontal beams. During the laying of the concrete hexagonal blocks, the horizontal and vertical surfaces of the slope of the laid concrete hexagonal blocks can be observed through the horizontal level bubble and the adjustable level bubble.
[0022] Step 4.5, after the concrete hexagonal blocks are laid, pull out the concrete hexagonal block laying positioning device, fill the joints with cement mortar, and tamp the mortar in the joints with a putty knife to ensure that the mortar is full.
[0023] Repeat steps 4.4 and 4.5 to lay the third and subsequent layers of concrete hexagonal blocks until all layers are laid.
[0024] Step 5: Pointing
[0025] After the grouting is completed, use a putty knife to point the joints, and the joints should be slightly lower than the concrete hexagonal block panel by about 3 to 5 mm. After the grouting is completed, wait for the mortar to set after the initial setting and before the final setting, promptly remove the pollutants on the concrete hexagonal block panel to prevent excess mortar from hardening on the panel and affecting the appearance.
