Everyone dreams of having a beautiful garden where they can walk and play, and usually meet up with friends. You can also plant some flowers and plants to enjoy yourself. Xiao Bian will tell you about the garden design and I hope to help you design the garden. Garden Design: Plant Configuration Issues Plant species should choose flower shrubs, small trees, bulbous flowers and perennial flowers with beautiful posture, short, shallow roots, strong wind resistance. Since the roots of perennial woody plants have strong penetrating power to the waterproof layer, the planting species should be determined according to the thickness of the covering soil. Covering soil 100cm thick can plant small trees; thick 70cm can plant shrubs; if covered with soil 50cm thick, you can plant low shrubs, such as Rosaceae, peony, gold and silver vine, oleander, small pomegranate, etc.; if the soil is 30cm thick, Choose annual herbaceous plants such as grass flowers, herbs, and vegetables. Garden Design: Structural Roof Load Usually the roof structure has been completed when the roof garden is designed (partially built), and how much weight the roof structure can bear is a prerequisite for our roof design. If the design exceeds the design load on the top of the building, it will cause the roof structure to be in danger at any time. This is a taboo for the roof garden design. Therefore, we should consider the weight range of the design content, the thickness of the planting soil, the maximum size of the tree, and so on. Garden design: waterproof and drainage Usually, the original roof is in the form of a slope that is drained through the roof surface, and the rainwater is led to the drain, and the roof is made of a waterproof layer. If the professional treatment is not carried out after the design of the roof garden, the rainwater on the roof cannot be quickly discharged from the water outlet, which will cause problems such as water accumulation on the roof, damage to the water layer of the plant roots, water leakage, and drowning of the roof plants. Therefore, we should consider the organized drainage of the roof when designing the roof greening. The roof garden special drainage board needs to be laid between the roof and the planting soil. The special drainage board of the roof garden does not hinder the free drainage of the roof, and has some water storage function to keep the roof plants. The moisture, the practice is as shown below (from the bottom up): roof structure - waterproof board - non-woven layer -5 ~ 10cm thick medium coarse sand - suitable thickness of light planting soil - roofing plants). In the actual project, the special drainage board for the roof garden has been widely used, and its effect has also been tested in practice. Garden design: to prevent plant root puncture problems If the root system of the roof greening plant does not use the blocking measures, it will cause certain damage to the structure of the roof. Even on a roof with only a waterproof layer or a pressed layer, the seeds of some plants fall on the roof due to the flow of air, and under certain conditions, the plants can grow stubbornly. The consequence is that the roots penetrate the waterproof layer and even the structural layer, thereby rendering the entire roofing system useless. In the garden without selling, due to the presence of the coating, an environment that is more conducive to plant growth is produced. Some other exotic plants are generally more viable than our pre-planted plants, which continue to erode the territory of other plants. In addition, the roots of grasses are quite developed and have strong penetrating power, and the destructive power to the waterproof layer and the structural layer is also large. Therefore, when constructing gardens on the structural layers of buildings, it is necessary to guide and limit the growth of plant roots. Otherwise, the penetration of the plant roots into the waterproof layer will cause the waterproof function to fail; the plant roots penetrate the structural layer and cause more serious structural damage. In summary, from the perspective of economy and safety, the establishment of plant root barriers is indispensable for the construction of garden roofs. If you ignore the setting of the plant root block, it will cause serious consequences due to small loss. Garden design: wind resistance In the design of the roof garden, for the sake of function and aesthetics, it is sometimes necessary to design some structures, and the essays stand on the roof. If we must design these, we will encounter a pair of contradictions. A. The roof tends to have a lower wind and a larger surface, so the frame foundation needs to be stronger. B. There is no condition on the roof to bury the foundation deep in the soil. It is not desirable to damage the roof waterproof layer on the roof. . This is a contradiction. The way to solve this contradiction is to design a basis for amplification. While doing a good job in garden design, we should pay most attention to the related work of decorative design, which is conducive to us to do a good job in decorative design work.
