In recent years, roofing planting, particularly in the aspect of arbor planting, has rapidly developed in China. The technical requirements of roof planting are extremely high, from natural soil to light-weight matrix; from laying simple drainage layers to water storage and drainage technologies; the technology of … comprehensive utilization of rainwater is continuously developed and advanced from the simple selection of plants suitable for the roof environment to the scientific cultivation of plant materials suitable for the roof environment. For example: chinese patent CN201920500499.0 discloses a green building roof planting system, which comprises a planting roof and a water circulation device; the planting roof comprises a roof structure layer, a heat insulation layer, a waterproof layer, a root separation layer, a drainage layer and a planting soil layer which are sequentially arranged from bottom to top, wherein a drainage flower pipe is arranged in the drainage layer; the water circulation device comprises a gutter and an irrigation pipe, wherein a filter funnel and a water storage box are arranged inside the gutter, a first filter layer is arranged at the top of the filter funnel, a second filter layer is arranged at the bottom of the filter funnel, backflow holes are formed in the side faces of the filter funnel, the end portion of the drainage flower pipe penetrates through the gutter and is inserted into the backflow holes, a sedimentation barrel is arranged inside the water storage box and is located below the filter funnel, the sedimentation barrel is communicated with the bottom of the filter funnel, a first overflow port is formed in the side wall of the sedimentation barrel, the bottom end of the irrigation pipe extends into the water storage box, the top end of the irrigation pipe is matched with a planting soil. The utility model discloses a can collect the rainwater and with rainwater cyclic utilization in the irrigation of planting the roofing, reduce water wasting of resources. Chinese patent CN201610030299.4 discloses a construction method for water guiding and water proofing of roof-planted carpet plants, comprising the following steps: (1) cleaning the roof and keeping the roof flat; (2) dredging a sewer; (3) for a cement roof, ensuring that the drainage gradient of the cement roof reaches 1% -3%, and checking whether the roof has water leakage or not; for the iron sheet roof, checking whether water leaks from the connecting seam and the iron nails of the iron sheet roof, and coating an antirust agent on rusty points of the iron sheet roof; (4) after leakage repairing, directly paving a self-adhesive modified asphalt waterproof rolling plate on the cement roof, paving the self-adhesive modified asphalt waterproof rolling plate to a position 15cm away from the parapet, and then paving cement mortar or paving no cement mortar but reserving an aluminized film on the upper surface of the self-adhesive modified asphalt waterproof rolling plate; for the iron sheet roof, laying a self-adhesive modified asphalt waterproof roll plate on the roof, and continuously laying a plastic water chute and planting non-woven fabrics; (5) and (5) carrying out carpet type plant planting.

Be provided with automatic return water irrigation mechanism 8 in the plant culture basic unit 44, automatic return water irrigation mechanism 8 includes rainwater collection well 81, irrigation pipeline 82 and water storage tank 83, rainwater collection well 81 sets up in plant culture basic unit 44, rainwater in the rainwater collection well 81 passes through in the draining layer 811 gets into plant culture basic unit 44, be provided with water level floater 812 in the rainwater collection well 81, water level floater 812 connects water control valve 831 of water storage tank 83, irrigation pipeline 82 lays in plant culture basic unit 44, and irrigation pipeline 82 communicates to rainwater collection well 81.

When the moisture in the plant culture medium layer 44 is insufficient, the drainage layer 811 supplements the rainwater in the rainwater collection well 81 to the plant culture medium layer 44 by using osmotic pressure, so that the height of the water level floating ball 812 is reduced, the water control valve 831 of the water storage tank 83 is opened, the water storage tank 83 supplements the water for the plant culture medium layer 44 through the irrigation pipeline 82, meanwhile, the irrigation pipeline 82 supplements the water for the rainwater collection well 81 until the water level floating ball 812 rises to the set height, and the operation is stopped. The water level float 812 descends and the process repeats. The movable backwater irrigation mechanism 8 can realize automatic water replenishing, and manpower and water resources are saved on the basis of meeting the plant growth requirement.

In step 5), the arbor 4 is planted in the plant medium layer 44 by bagging. The bagging planting of arbor 4 can control the growth rate of root, reduces 4 root system growths of arbor and the influence to overhead structure. The arbor 4 is a small arbor or a sub-arbor, and the arbor 4 is a local small arbor or a sub-arbor with developed fibrous roots and weak root system puncture property, so that the survival rate of the arbor can be effectively improved.

An insulating layer 6 is further arranged between the first root isolating layer 41 and the planting groove, and the shape of the insulating layer 6 is matched with that of the planting groove. The heat preservation 6 is the expanded perlite heat insulation layer, avoids concrete bottom plate 3 uneven deformation of being heated easily.

A second root separating layer 7 is further arranged between the heat preservation layer 6 and the planting groove, and the shape of the second root separating layer 7 is matched with that of the planting groove. The second root separation layer 7 is made of fiber reinforced plastics, so that on one hand, the influence of the root growth of the arbor 4 on the overhead structure can be further eliminated; on the other hand, the second separates the advantage that root layer 7 has the quality light and non-deformable, on guaranteeing the firm basis of whole arbor built on stilts planting structure, can not cause great load for former building roof structure, avoids former building roof structure's weak department to damage.

The working principle is as follows: through setting up built on stilts brick wall and concrete bottom plate on former building top surface, found built on stilts formula roof garden arbor planting structure, because the position of built on stilts brick wall corresponds the support beam column of former building top surface below, the load of arbor planting structure directly transmits for on main, the secondary beam column of building roof below through built on stilts brick wall, and the building roof does not directly bear the load to weak component is destroyed in avoiding roof structure. Therefore, the bearing capacity of the roof structure of the building is effectively improved and the stability of the arbor planting structure of the roof garden is improved by changing the framework form and the force transmission mode of roof planting. In order to eliminate the influence of arbor root growth on whole overhead planting structural stability, adopt the first root layer that separates that copper foil child SBS modified asphalt waterproofing membrane made and the second that fiber reinforced plastics made to separate the root layer, form duplicate protection, avoid the arbor root system to pierce through.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
