Problems solved by technology
[0002] According to the needs of most greening projects at present, in some greening projects, some trees are planted on the roof of the underground parking garage after being covered with soil. The planting soil is light soil and the thickness of the soil layer is insufficient. Conventional pile making and piling will not be implemented or cannot be achieved. Stability requirements, such as projects with high requirements for landscape effects, if the conventional pile-making and piling construction techniques on the ground (traditional fir piles, well-shaped or triangular supports, poor appearance effect) will not only destroy the overall landscape effect, but also cause certain degree of waste of space
[0003] However, the traditional independent underground support technology has high requirements on the vertical soil bearing capacity acting on the support, and local nylon straps limit the growth of plant roots and the cost is high.
[0004] Traditional underground support requires mud balls to be wrapped in a large volume and area. All mud balls have a poor effect on root germination and hinder root growth.
[0005] The maximum thickness of traditional roof covering soil is 1.5m light soil, and the traditional planting method has weak wind resistance, mainly due to the insufficient bearing capacity of the soil, resulting in insufficient anti-overturning ability of trees
[0006] The cost of traditional independent support equipment is relatively high

Embodiment Construction
[0049] see Figure 1 ~ Figure 3 , the integral type arbor underground support construction method of the present invention, it comprises,
[0050] 1) Fabrication and installation of the bottom plate
[0051] The concrete piles are prefabricated, and the concrete piles 1 are connected by galvanized square steel 2 (hollow), on which steel bars 3 are bound vertically and horizontally to form a grid structure;
[0052] 2) Mud ball dressing
[0053] The arbor mud ball 4 is wrapped with a steel wire mesh sheet 5, and two reinforcement waist hoops 6, 7 are arranged around the mud ball; The surface is bound with the first waist hoop with a steel wire rope; in this embodiment, the surface of the mud ball is bound with the first waist hoop with a steel wire rope in the form of a five-pointed star
[0054] 3) Earthwork stacking and modeling:
[0055] Turn over the earthwork to the reinforced base plate for stacking and modeling, the thickness of the soil layer is 1-2m, and the thickn...

An integral type arbor underground support construction method comprises the first step of manufacturing and installing of a bottom plate, the second step of mud ball binding, the third step of earthwork stacking and modeling, the fourth step of digging of tree holes, the fifth step of connection of steel bar waist hoops and the bottom plate, and the sixth step of soil covering and ridge retention. The integral type arbor underground support construction method can ensure the stability of arbor planting, can also ensure the overall landscape effect after planting, is suitable for arbor planting in various greening projects, and is particularly suitable for projects with relatively high requirements for overground landscape effects.
