7. The three-dimensional net structure grid direction used by the slope greening structure jointly supported by the hanging plates and the sun shield is inclined upwards, so that soil filling is facilitated, soil and the like are not prone to slipping, rainwater storage and the like are connected, and the soil is not prone to being taken away by scouring.
8. The used catch basin of the domatic afforestation structure that this link plate and sunshading board jointly strutted distributes inside the link plate, prevents the vegetation degradation, prevents the arid, plays the effect of water conservation, and the catch basin dispersion prevents that power is too concentrated.
9. The water storage tank for the slope greening structure supported by the hanging plate and the sun shield in a combined mode is solidified through cement, the upper half part of the water storage tank is of a net structure, a small channel is formed in the center of the lower half part of the water storage tank, the baffle plate is used for blocking a small amount of water, and when the water is enough, the water flows down and flows out from the small channel, so that rainwater is supplied; when sudden rainstorm occurs, enough water flows into the water replenishing and draining pipe from the large channel to be drained.
11. The used moisturizing drain pipe of domatic greening structure that this link plate and sunshading board jointly strutted can carry out timely moisturizing and drainage, and 1 ~ 2 months mends a water reduction maintenance time and cost. The water replenishing pipe has sandwiched layer and transition layer on two sides, and inside water absorbing resin and sand mixture. The water storage tanks are distributed around the water replenishing pipes, the water storage tanks store rainwater in a rainwater weather, and when the rainwater is excessive, the excessive rainwater enters the water pipes through the interlayers to be discharged; in dry weather, the water storage tank receives water of the water replenishing pipe through the interlayer.
13. The used moisturizing drain pipe transition layer of domatic greening structure that this link plate and sunshading board jointly strutted has corrosion resistance, and the inner wall is smooth, the liquid flow of being convenient for.

14. The vegetation concrete used for the slope greening structure supported by the hanging plate and the sun shield in a combined mode can be added with ceramsite with certain density, so that the vegetation concrete is resistant to scouring and evaporation, can prevent soil particles from losing and nutrient from losing, and is soaked in fertilizer firstly, and the fertilizer is slowly released.
15. The vegetation concrete used for the slope greening structure jointly supported by the hanging plates and the sun shield can be used for planting vegetation, greening side slopes, roads and the like, and can be fixed to ensure that the slope greening structure is not easy to fall off.
16. The hanging plate for the slope greening structure jointly supported by the hanging plate and the sun shield adopts a hanging plate type, and the hanging plate is hung and fixed through anchor rods according to regional blocks, so that local repair can be performed, the later-stage repair workload is reduced, and local repair is facilitated.
17. All materials of the light pressure plate used by the slope greening structure supported by the hanging plate and the sun shield in a combined manner can keep stability for a long time in a humid environment, and are not easy to rust, and meanwhile, the light pressure plate is sensitive to water pressure, and can compress and extend the spring connected with the light pressure plate according to the water pressure and move up and down; in addition, the spring has small mass, can reduce the influence of the spring on the compression amount of the spring, can ignore the mass of the spring, has large elastic coefficient, is easy to be compressed and extended by the change of pressure, and can drive the lower opening-closing plate connected with the spring to control the flow of water under the flow. When the water pressure is low and the spring is not compressed, the opening plate is in an opening state, and rainwater can flow down through the soft drain pipe; when water pressure is large and the spring is compressed, the water pressure is in a closed state, so that rainwater cannot flow down directly but flows into a water replenishing drain pipe on one side to replenish or discharge vegetation below, and further, the rainwater is prevented from directly flushing the vegetation below, and the loss of nutrients such as soil is avoided.
19. The sun shield can prevent the greening structure and the vegetation below from being directly exposed to strong sunlight, reduce the evaporation of nutrients such as water and the like, protect the greening structure and the vegetation, reduce the later maintenance and prolong the service life. The sun shield is made of corrosion-resistant aluminum alloy metal plates with holes and the like, and is high in strength and strong in pressure resistance, so that the sun shield can be prevented from being crushed when the water amount is large, and rainwater is prevented from being leaked in a large amount. When raining, the rainwater can be accumulated, and the amount of the rainwater left can be controlled to judge the accumulated amount of the rainwater. When the water amount is small, the sun shield can directly flow down for water supplement, and meanwhile, the sun shield can enter a water supplement pipe for water supplement; when the water yield is big, the moisturizing drain pipe on the accessible sunshading board goes out, avoids directly flowing down to erode afforestation structure and vegetation, reduces the loss of nutrients such as soil, destroys the afforestation structure.
