Garden water requires a stable and beautiful waterfront to maintain a certain area ratio between land and water, and prevent land from being flooded or the waterfront from collapsing, or the water body from collapsing due to frost heaving, anchorage, wind and waves, etc. , destroyed the original intention of design. Therefore, it is necessary to build bank protection and slope protection on the edge of water body. Garden revetment can be divided into natural type and integral type according to section shape. Large water bodies or regular water bodies often adopt the form of integral straight revetment, which is composed of bricks, concrete and stones. However, small water bodies or water bodies with stable water level in gardens often adopt natural rock revetment to make them into shapes such as rocks, stones, cliffs and caves.
When designing a barge, it is necessary to determine the plane position and the elevation of the top of the dike. The revetment adjacent to the urban river is constructed according to the plane position specified by the urban water system, while the position of the revetment in the park is determined according to the architectural design of the lake. The constant water level line on the plan shows the position of the water surface, and the elevation of the dike top should be higher than the highest water level to ensure that the lake will not flood into the shore and land surface due to wind and waves, but the specific situation depends on the actual situation. When laying, it is required to be firm and stable, and the revetment is mainly driven by piling or firewood sinking, often with lath, rubble concrete, concrete and reinforced concrete, with mortar lath or mortar rubble jointing, brick plastered with waterproof mortar, reinforced concrete and rockfill as the wall, and lath, rock, concrete block and vegetation as the roof. Slope protection is mainly to prevent landslides, reduce the erosion of surface water and wind waves, and ensure the stability of bank slopes. Common methods are: riprap slope protection plus willow trees and paving stones.
