Description

Greening arbor fixing device

Technical Field

The invention relates to the field of landscaping equipment, in particular to a greening arbor fixing device.

Background

With the advance of urbanization process, the development of urban construction is fierce, and high buildings and forests in cities are standing and have scale-to-scale ratios. Along with the reduction of greening area in cities, the urban problems such as heat island effect and the like are increasingly highlighted, and the connection between cities and nature is continuously broken. Landscaping is an important means for relieving urban ecological environment problems, and under the condition of limited urban landscaping land, the landscaping efficiency is improved, and the landscaping survival rate is ensured.

In eastern coastal cities such as Shanghai, the wind resistance of trees in landscaping is high under the influence of extreme weather such as typhoon. Landscaping transplantation, new planting of trees, especially large trees, require fixing devices to ensure their survival rate due to the tendency of lodging due to underdeveloped fibrous root systems. Especially in roof greening, which is an important greening type in urban high-density areas, the requirements of the arbor for preventing wind and fixing root are particularly outstanding due to large wind power and thin soil layer.

The existing fixing device in the market is single in type, and the bracket is mainly erected by utilizing a fir rod or a bamboo pole to support and fix, an iron rod lantern ring is used for fixing, a wire is used for fixing and the like. The whole fixing efficiency of the devices is not high, most of the existing devices can not meet the lodging-resistant requirement in greening areas such as roof greening with extremely high requirements for wind prevention and root fixation, so that most of the existing devices are ground cover plants, shrubs or small trees in existing roof greening, and the large trees are rarely planted due to the limitation of roof fixing technology. Meanwhile, the existing fixing device has large influence on site landscape by the large-area exposed support rods, and the normal flow of sap can be seriously hindered by the modes of iron hoop reinforcement and the like, so that the movement of a forming layer is greatly damaged, and even new decay is caused.

In urban afforestation land shortage day by day, roof greening is increasingly popularized now, arbor fixing device demand is constantly increasing, requires constantly to promote. The research has great significance for developing the fixing device which is efficient and attractive and can really solve the problems of wind prevention and root fixation of the arbor.

Chinese patent document CN 104584969 a describes a method for planting trees for roof greening to prevent wind and fix roots, which is to reinforce the roots, trunk and crown of the planted trees respectively through a reinforced concrete root fixing frame, a trunk fixing frame and a steel-structured crown wind-resistant frame, thereby forming three-dimensional wind-resistant reinforcement from bottom to top, effectively improving the wind-resistant performance of the trees planted on the roof, making it possible to plant trees for roof greening, especially large-scale trees, and making the greening landscape of urban buildings more beautiful, three-dimensional and diversified, and also more safe and reliable. But the structure has the problems of insufficient strength and difficult installation, disassembly and transplantation. The appearance of the supporting structure of the trunk fixing frame is not beautiful enough.
