The device continuously arranges pine pile revetment devices on the normal water level and flood level elevations of the lake revetment. The device can adjust the size and shape of the wire mesh according to actual needs to meet the protection needs of different water flow conditions and bank slope boundary conditions; protect against water and soil erosion caused by water scouring and periodic floods, and use the holes and grooves of the pine piles to meet the activity channels of microorganisms, small animals, etc. in the soil. For the initial rainwater, when it passes through the waterfront plant planting area and when it is filtered through the block stone layer, the rainwater is preliminarily purified to reduce the content of pollutants in the rainwater, while keeping the soil moist, so that the waterfront plants are in a favorable habitat; but lakes often have multi-level revetments, which is a more complex ecological environment, resulting in unsatisfactory restoration effect of the device.
