Maintenance management of roof greening?

Private roof garden, because the garden area is generally small, only a few tens to more than 100 square meters. This small roof garden is generally maintained by itself, enjoying the pleasure of a small green world in labor, and the content of maintenance is not more complicated than other greening maintenance: daily watering and fertilization, pest control, seasonal plant replacement, loosening soil and weeding, etc.

The viewing platform on the roof and between buildings of large-scale roof gardens or residential basements, civil air defense basements and underground garages shall be the responsibility of residential property management after completion, adopting a three-level management system, which mainly refers to the maintenance and management of all kinds of ground covers, flowers and trees in the main landscape of the garden. Of course, there are roof irrigation, water supply, supporting lawn lights, landscape lights, background music and other electrical facilities, as well as roof waterproof and drainage management. This work should generally be undertaken by full-time personnel with experience in landscaping and planting management.

In the process of daily use, managers should pay attention not to add large-scale scenery beyond the original design scope at will in the roof garden to avoid roof overload. Generally, the power supply and water supply pipelines of roof gardens are embedded in the water storage and drainage partition board. When maintaining hydropower equipment and systems, special attention should be paid not to damage the original roof waterproof layer and green partition structure. If damaged, the water storage and drainage plate and filter cloth need to be replaced.

The design of roof garden landscape garden drainage engineering should consider the use of light and thin materials, especially the use of plate drainage system engineering, change the past pipes and collecting wells, set drainage ditches, set drainage sewers, set drainage blind ditches, and reduce the weight, thickness and cost. Only when architectural design, structural design and hydropower equipment cooperate with each other can it be carried out smoothly. When all kinds of jobs are coordinated, when the landscaping design jobs put forward various technical requirements related to building types, structural calculation and hydropower jobs according to the needs of landscaping, the related jobs should treat the process design requirements in industrial building design with a serious attitude, conduct research, and collect information on roof gardening and plant growth. Because roof gardening is not just as simple as putting a few pots of flowers on the roof, building a few flower ponds and counting the load-bearing of the roof structure. The technical requirements of roof garden greening are closely related to architecture, structure, hydropower and environmental design. For structural design, roof garden not only requires increasing roof load, but also puts forward new requirements for seismic design of building structural system. When the structural type of work matches the landscape engineering, under the premise of meeting the landscape needs, the larger concentrated load should be set on the bearing wall of the column top or beam as far as possible. Similarly, roof gardening also has corresponding technical requirements for hydropower and heating, such as roof greening and watering, sprinkler irrigation, water supply and drainage, etc. Roof lighting and a small amount of power supply equipment. Some even require a small greenhouse on the roof, which needs heating in winter.

Perfect and reasonable design depends on construction. In the construction of roof garden, the cooperation between civil engineering and garden engineering is another key to the construction of roof garden. In landscape engineering, a large number of embedded iron pieces and supports should be reserved on the roof, which adds a weak link to the overall waterproof layer of the roof. As long as there is a little damage on the waterproof layer, it may cause roof leakage. Therefore, it is necessary to combine soft waterproof coating with waterproof coiled material in order to effectively waterproof.
