With the progress of aesthetic requirements for landscape engineering, the landscape design of retaining wall plays an important role in the visual effect of rich landscape space. When stopping the design of retaining wall landscape construction mode, we should follow its basic criterion, create space in harmony with environment and clothes according to style, use linearity, plane space, pattern and other ways to structure landscape, and innovate the way of retaining wall, so as to make its space more rich, diverse and artistic. Retaining wall design means the shape and height of the retaining wall. According to the environmental conditions, the "five modernizations" design method is usually adopted, that is, to turn high into low, to turn whole into zero, to turn big into small, to turn steep into slow, to turn straight into curved. These five designs have changed the single design of the retaining wall's vertical steepness, separated from plants, reduced the adverse view of the retaining wall and increased the amount of greening, which is not only conducive to the invention of microclimate, but also conducive to the improvement of the visual quality of the space environment. Retaining walls are usually designed in the following five ways:
1. Turn High to Low
The soil quality is good, and the height difference is less than 1 meter. The design of retaining wall should reduce the height, which is 0.4-0.6 meters. Top part of the slope, with flowers, shrubs to stop greening. If the slope is large, in order to ensure the stability of the soil slope, hollow prefabricated cement square brick can be used to fix the slope, and then flowers and plants, shrubs in the gap greening. It is not only beautiful and ecological balance, but also labor-saving, time-saving and investment-saving.
2. Divide the whole into zero
The platform with large height difference, which is more than 2.5 meters, can be made into a retaining wall, which can produce a sense of pressure, but also easy to form a whole masonry. It should be integrated into a zero-dividend multi-step retaining wall building. The platform in the middle of the fall should be greened with shrubs with strong appreciation, such as lotus, cloves, elm leaf plum, Rosa davidiana, etc., or vine greening, such as Broussonetia quinquefolia, Rosa wilfordii, and vine. Ben Rose et al. If the soil is not good, stop changing it. This design relieves the visual bulkiness of the wall and unifies the aesthetics and engineering economy.
3. Turn Big into Small
In some beautiful areas with special requirements, when the soil quality is not good, the retaining wall should be changed from big to small, even if the appearance of the retaining wall changes from big to small. The method is that the whole wall is divided into two parts, and the lower part is widened to form a planting pond for filling and greening. It can also be designed as a pool, stocking fish and aquatic plants, or a fountain where the landscape is bright, forming a very enjoyable spatial effect.
4. Turn steepness into gentleness
The vertical retaining wall is designed to be inclined, the same height of the retaining wall because of the distance between the interface of the retaining wall and the human eye, the original invisible content can now be seen, the visual field space has become open, the environment has become more bright.
5. Turn Straight into Music
Retaining wall from straight curves, straight lines into curves, highlighting dynamic, more able to absorb people's vision, give people a comfortable feeling, especially in some special places, such as memorial tablets, open-air theatres, stadiums, etc., fluent curves make the space constitute a clear visual center, more conducive to highlighting the main scenery.
