Description

Tree fixing system for aerial ecological courtyard

Technical Field

The invention belongs to the supporting technology of building gardens, and particularly relates to a tree fixing system for an aerial ecological courtyard.

Background

In the aerial ecological courtyard designed for building a balcony, trees can be planted on the greening courtyard or the greening platform due to the fact that the space of the greening courtyard or the greening platform is greatly increased. Trees planted in the soil on the ground can be rooted into deep soil to keep self stability, but in the air ecological courtyard built, the bearing strength of the building structure is considered, the thickness of the soil layer paved on the platform is generally not more than half a meter, so that the trees planted in the air ecological courtyard have the following two problems:

the tree is higher than a bush, is easily influenced by wind weather, and is possibly blown down or inclined by strong wind due to insufficient support when the tree species are subjected to strong wind in a certain direction, so that in the tree planting process of an ecological building, a main trunk needs to be vertically fixed and the tree posture needs to be adjusted through an external support structure so as to prevent the main trunk from inclining or falling due to unstable gravity center, and the tree can stably grow.

The traditional tree support mainly comprises the steps of bundling or binding a trunk by ropes, iron wires, plastic belts and the like, or nailing the trunk by long iron nails, cramps and the like, or realizing support diameter adjustment in a butt-clamp hoop mode by combining a plurality of iron sheets, and then connecting fir, battens or steel pipes supported by inclined struts; the binding, binding and iron sheet hoop is easy to loosen and age after being used for a period of time under wind load in use, and the support is obviously not firm and stable; the fixed support mode of drilling long nail holes on the trunk obviously damages the inner structures of the barks and the branches, can decay trees and prevent the transportation of nutrient moisture liquid of the trees from influencing the healthy growth of the trees; in the process of the inclination of the tree trunk, the support state of the inclined trunk is inconvenient to adjust; in addition, a plurality of trees can be planted on the same greening yard or greening platform, and the independent supporting structures have the defects of insufficient space for adjusting the tree radial direction, insufficient support for expanding combined groups of trees, incapability of recycling among the supporting structures and the like.

The soil covering layer of the aerial ecological courtyard is thin, the soil space for fixing trees by rooting is small, the root systems are not stable enough, the self weight or wind resistance of the upper structures of the slightly large trees is large, the trees need to be deeply covered with soil and fixed when the gardens or the courtyards are planted, and the trees need to be prevented from being covered with soil insufficiently and being unstable in gravity or being blown down or inclined by strong wind.

The existing buried root fixing method basically adopts the binding bands such as the grass ropes, the cloth strips and the non-woven fabrics to fix the tree root soil balls on the materials such as bamboo poles, battens and the like buried in the soil layer, and the strength of the existing buried root fixing method is insufficient, so that the existing buried root fixing method is easy to break in buried construction and later stress; the soil layer near the tree pit is short in length, and soil balls are fixed and only can be connected with or influence a small amount of soil body nearby; meanwhile, the bamboo poles, the battens, the straw ropes, the cloth strips, the non-woven fabrics and other binding bands are easy to corrode, age and damage when being soaked in humid and acidic soil media, wrapped root soil balls can lose stable root fixation quickly, the depth of covering soil is not enough, the soil balls are loosened in the rainwater erosion inflow process, soil attached to the soil balls is lost, the root systems are loosened and unstable due to the factors, the soil balls can incline or topple when meeting certain wind resistance, and the purposes of planting the slightly large trees for fixing the roots and purifying air, beautifying the environment, adsorbing and reducing noise cannot be really achieved.
