DETAILED DESCRIPTION

[0017] [Example 1] First, make a good foundation for the bank protection. The foundation should be solid and flat. Prepare for lifting. First, insert one end of the lifting rope into the Figure 1 As shown in the figure, first hoisting hole 10 on the far left, then pass through the first hoisting hook 19 on the left, make sure the connection is firm, use the other end of the hoisting rope to pass through the second hoisting hole 13 on the far right, then pass through the second hoisting hook 20 on the right, make sure the connection is firm, forming a closed loop, then take another hoisting rope and pass it downward through the first guardrail reserved hole 11 on the left, and then upward through the second guardrail reserved hole 12 on the right, forming a closed loop, use these two hoisting ropes for hoisting, first hoisting at the head end of the revetment foundation, after one device is hoisted, hoist the next device in sequence. Figure 7 As shown, when two adjacent devices are combined together, the connecting protrusions 8 and the connecting grooves 9 are engaged together, and a gap of 2 cm is left between the connecting protrusions 8 and the connecting grooves 9. If the gap is too small, it will be too difficult to connect them. The above is a rough connection, and then screws are passed through the screw connection holes 7. The connection is reinforced by screws, and the various devices are connected to each other to form a whole to protect the embankment.

[0018] [Example 2] The shore side of the device is backfilled and compacted with earth, such as Figure 3 As shown, the tooth wall 14, the main rib 4 and the auxiliary rib 5 extend into the earth, playing a role of close integration with the embankment.

[0019] [Example 3] When water flows through the device, the curved wall 2 uses its arc shape, which conforms to fluid mechanics. Under the diversion effect of the curved diversion dam 3, the water flows up along the curved wall 2, which can convert part of the kinetic energy of the water into potential energy. In the process, the impact energy of the water flow is reduced, which can have a slowing effect on the speed of the water flow. The diversion effect of the curved diversion dam 3 also effectively reduces the flow velocity. The combination of the above two effectively reduces the impact of floods on the embankment and slows down the impact on the downstream river embankment.

[0020] [Example 4] like Figure 9 As shown, when adjacent devices are connected together, the adjacent arc-shaped diversion dams 3 are merged together, and the climbing steps 15, climbing handles 16, and top climbing handles 21 are combined to form a climbing ladder, which is used for emergency rescue and for clearing river sediment.

[0021] [Example 5] In another case, when a person falls into the water, the rescuer descends along the climbing step 15 and the climbing grab 16 to the base 1 to take the life rope hanging on the hook 18, goes into the water to rescue, and after the rescue, ascends along the climbing step 15 and the climbing grab 16 to the shore. The emergency rescue equipment is hung below the top of the wall to protect it from sunlight and prevent ignorant children from taking the equipment at will. [Example 6] When the soil water on the bank exceeds the saturation state and seepage occurs, the water flows out through the small holes of the seepage holes 17 of the device. The small holes will retain mud and sand and seep out clear water, which is beneficial to soil and water conservation.

[0022] [Example 6] like Figure 10 As shown in the figure, when the revetment height is greater than 2 meters, the inclined horizontal type is adopted. Figure 11 As shown, the design at the curved river channel adopts a curved style.
