Definition in landscape engineering: the facilities built at the junction of water body edge and land in landscape architecture to avoid being damaged by various natural and man-made factors and protect water body, and stabilized by engineering measures.
Garden revetment can be divided into integral and natural types according to the cross-section shape. For large-scale water bodies, water bodies with large wind and waves and large water level changes, and garden water bodies with basic rules, the form of integral straight revetment is often adopted, and the shore wall is built with stone, brick or concrete. For small water bodies and a small part of large water bodies, as well as water bodies with stable water levels in natural gardens.
Natural rock slope protection or vegetation gentle slope protection is often used. Natural rock revetment can be made into diagenetic, stony, cliff, headland and other shapes, and it takes the form of upward extension and downward contraction and horizontal suspension.
Garden revetment is a kind of protective engineering structure, which consists of foundation, wall and roof. , and it is required to be firm and stable during construction. Piling or sinking firewood rafts are often used as measures to strengthen the foundation of revetment. Choose a solid boulder as a block, or use a lime soil layer with a widened cross section as a foundation to build a revetment on it. The revetment should be built directly on solid soil or rock foundation.
If the foundation is weak, it must be dealt with. In recent years, in the construction of garden revetment in southern China, the method of widening the foundation is often used to reduce or cancel the foundation treatment project. Revetment is usually based on rubble, block concrete, concrete or reinforced concrete.
Use grouting stone, grouting block stone for jointing, brick for plastering waterproof mortar, reinforced concrete and rockfill as wall; Use strip stones, rocks, concrete blocks and vegetation as roofs. In places rich in bamboo and wood, bamboo, wood, round strips, bamboo chips and wooden boards are also used as bamboo piles for revetment after anticorrosion treatment. The revetment shall be provided with expansion joints at regular intervals.
Its structure and caulking materials should be economical, durable and convenient for construction. The water surface after bank protection in cold areas needs frost heaving treatment. The method includes: filling graded sand, coke residue and other porous materials that are easy to filter water; Masonry with large masonry structure size shall be compacted with solid, pressure-resistant and impervious materials such as lime soil.
