[0024] It can be understood that the polystyrene board 6 is used as the main backfill material in the backfill cavity 4, and the layer of ceramic soil particles 8 is used to plant the vegetation layer 9, so that the weight of the backfill of the overhanging structure 2 is greatly reduced, and the aesthetic appearance is improved by the planting layer.

[0025] Specifically, a second waterproof layer 10 is spread on the upper surface of the upper polystyrene board 6, the second waterproof layer 10 is connected with the first waterproof layer 5, the second waterproof layer 10 and the first waterproof layer 5 are both made of SBS modified asphalt roll material, a water storage cavity 11 is formed between the second waterproof layer 10 and the layer of ceramic soil particles 8, a plurality of cotton ropes 15 are fixed on the surface of the support net 7 at intervals, the upper end of the cotton rope 15 extends into the layer of ceramic soil particles 8, and the lower end of the cotton rope 15 is located at the bottom of the water storage cavity 11.

[0026] It can be understood that the water storage cavity 11 is arranged, so as to facilitate the collection and storage of the rainwater or irrigation water received by the layer of ceramic soil particles 8, the water in the water storage cavity 11 is infiltrated into the layer of ceramic soil particles 8 through the capillary phenomenon of the cotton rope 15, so as to continuously provide water for the vegetation layer 9, and the second waterproof layer 10 and the first waterproof layer 5 are arranged, so as to prevent the water from penetrating into the overhanging structure 2 under the double waterproof measures.

[0027] Specifically, a plurality of first drainage holes 12 are arranged on the side of the water storage cavity 11 away from the parapet 1, the height of the first drainage hole 12 is close to the lower surface of the support net 7, a drainage pipe 1201 is connected to the outer end of the first drainage hole 12, and the drainage pipe 1201 is attached to the outer surface of the overhanging structure 2 and extends downward.

[0028] It can be understood that by setting the first drain 12, when the water level in the water storage cavity 11 reaches the height of the first drain 12, it is discharged through the first drain 12 and the drain pipe 1201, thereby controlling the water level in the water storage cavity 11, avoiding excessive water storage causing the self-weight of the overhanging shaped structure 2 to increase beyond the limit value, affecting the service life.

[0029] Specifically, the water storage cavity 11 away from the parapet 1 side is provided with a plurality of second drains 13, the number of second drains 13 is less than the number of first drains 12, and the second drains 13 are communicated with the drain pipe 1201, the second drains 13 are flush with the bottom of the water storage cavity 11, and the water storage cavity 11 away from the parapet 1 side is fixed with an opening and closing assembly 14 for closing and opening the second drain 13, the opening and closing assembly 14 includes a fixed plate 1401 fixed on the inner wall of the water storage cavity 11 and a water baffle 1402 horizontally sliding on the surface of the fixed plate 1401, the surface of the fixed plate 1401 is provided with a water passage for water, the water passage corresponds to the position of the second drain 13, the fixed plate 1401 is fixed on the inner wall of the water storage cavity 11 by cement, avoiding the use of bolts to damage the first waterproof layer 5 and the second waterproof layer 10, the surface of the fixed plate 1401 is provided with a sliding rail, the water baffle 1402 horizontally slides on the surface of the fixed plate 1401 through the sliding rail, the surface of the water baffle 1402 is fixed with a rack 1403, the fixed plate 1401 is rotatably provided with a connecting shaft 1404, the connecting shaft 1404 is vertically arranged, the lower end of the connecting shaft 1404 is fixed with a gear 1405, the gear 1405 is engaged with the rack 1403, and the upper end of the connecting shaft 1404 is fixed with a hand wheel, the height of the hand wheel is higher than the height of the vegetation layer 9.

[0030] It can be understood that because there is a lot of dust in the rainwater, and the clay particles will also fall a little dust, which will be deposited at the bottom of the water storage cavity 11 under the action of water flow, affecting the water storage capacity of the water storage cavity 11 and increasing the self-weight of the overhanging shaped structure 2, and the height of the first drain 12 is too high, so that the sewage deposited at the bottom cannot be discharged during drainage, therefore, the second drain 13 is regularly opened by the opening and closing assembly 14, so that the water flow discharges the dust from the water storage cavity 11, and the specific operation is to rotate the hand wheel to drive the gear 1405 to rotate, and under the cooperation of the gear 1405 and the rack 1403, the water baffle 1402 slides on the surface of the fixed plate 1401, the second drain 13 is opened, and the sewage flows out, and the water storage cavity 11 is stored with water again through artificial irrigation or rain.
