The structure includes three parts: a wall 1, a heat-insulating layer 2 and an ecological layer. The wall 1 can be made of concrete, masonry or other materials suitable for building structures, and its surface is coated with an anti-corrosion and corrosion-resistant layer to improve the durability and corrosion resistance of the wall 1. The anti-corrosion and corrosion-resistant layer can be made of epoxy resin, fluorocarbon coating or other materials with excellent protective properties to ensure that the wall 1 can still maintain structural strength and beauty after long-term exposure to the external environment.

[0023] The heat insulation layer 2 is located on the outer surface of the wall 1, and is used to reduce the conduction of external heat to the inside of the wall 1. The heat insulation layer 2 can be made of polyurethane foam material, extruded polystyrene board or other high-efficiency heat insulation materials to improve the heat insulation performance of the wall 1. In addition, in order to prevent plant roots from penetrating the heat insulation layer 2, a waterproof root barrier membrane 3 is provided between the heat insulation layer 2 and the matrix layer 4. The membrane has good waterproof performance and can effectively block the growth of plant roots, protecting the heat insulation layer 2 from damage.

[0024] The ecological layer is arranged on the outer surface of the insulation layer 2, and includes a matrix layer 4 and a vegetation layer 5. The matrix layer 4 is made of porous materials, such as peat soil, coconut bran or a mixed matrix, and has good water permeability and moisture retention. An integrated irrigation and drainage system is provided in the matrix layer 4 to maintain the water supply and drainage function of the vegetation layer 5. The integrated irrigation and drainage system includes an irrigation device, a return trough 14 and a water collection tank 15. The irrigation device is composed of a water storage tank 8, a water inlet pipe 6, a nozzle 13 and a first water pump 9. The water storage tank 8 is connected to the water collection tank 15 through a connecting pipe 18, and the water is pumped through the water inlet pipe 6 and the nozzle 13 by the first water pump 9 to irrigate the plants.

[0025] Furthermore, the water inlet pipe 6 includes a main pipe 11 and several branch pipes 12. One end of the main pipe 11 is connected to the water tank 8, and a first solenoid valve 10 is installed on the main pipe 11. The first water pump 9 is installed on the main pipe 11.

The green plants are inserted and planted in the planting boxes 21. The planting boxes 21 include an inner box 211 and an outer box 212. A plurality of water-permeable grooves 28 are arranged on the inner box 211 and the outer box 212. The inner box 211 is connected to the outer box 212 by a thread 23. A limiting assembly 24 is arranged on the inner bottom wall of the outer box 212. The limiting assembly 24 includes a limiting plate 241, a plurality of springs 242 and a plurality of limiting members 243. One end of the spring 242 is fixedly connected to the bottom wall of the limiting plate 241, and the other end of the spring 242 is fixedly connected to the inner bottom wall of the outer box 212. The positioning members 243 are evenly distributed along the circumference of the limiting plate 241, and several limiting plates 241 include a first connecting rod 2431 and a second connecting rod 2432. One end of the first connecting rod 2431 is fixedly connected to the bottom wall of the limiting plate 241, and the other end of the first connecting rod 2431 is provided with a first inclined surface. A through hole 25 for one end of the second connecting rod 2432 to pass through is opened on the peripheral wall of the outer box 212, and a second inclined surface is provided at the other end of the second connecting rod 2432. The first inclined surface and the second inclined surface are in contact with each other, and a dovetail groove 27 is provided on the first inclined surface. The extension direction of the dovetail groove 27 is parallel to the extension direction of the first inclined surface, and a dovetail block 26 for slidingly cooperating with the dovetail groove 27 is provided on the second inclined surface.

[0029] When installing the planting box 21, first insert the outer box 212 into the planting groove 22, then insert the inner box 211 with the green plants inserted into the outer box 212, and tighten the thread 23. At this time, the inner box 211 drives the limiting plate 241 to move toward the direction close to the inner bottom wall of the outer box 212, the spring 242 is compressed, the first connecting rod 2431 moves toward the direction close to the inner bottom wall of the outer box 212, the first inclined surface squeezes the second inclined surface, and the second connecting rod 2432 is limited by the through hole 25 and extends out of the outer wall of the outer box 212, realizing the card connection with the planting bag 20, so that the outer box 212 is firmly connected to the planting bag 20 and is not easy to fall out; when replacing the inner box 211, rotate the inner box 211 so that the thread 23 The spring 242 pushes the limit plate 241 in the direction away from the inner bottom wall of the outer box 212, and the limit plate 241 drives the first connecting rod 2431 to move in the direction away from the inner bottom wall of the outer box 212. The dovetail block 26 slides in the dovetail groove 27, and the second connecting rod 2432 is limited by the through hole 25 and slides along the extension direction of the second connecting rod 2432. At this time, the end of the second connecting rod 2432 away from the first connecting rod 2431 is contracted relative to the inside of the outer box 212, so that the second connecting rod 2432 does not protrude from the outer wall of the outer box 212, so that the outer box 212 can be taken out of the planting bag 20 together for easy replacement.

[0030] In order to realize automatic irrigation, the system is equipped with a main control module, a data acquisition and processing module, a storage module, a human-machine interface module and an irrigation module. The main control module is controlled by a single-chip microcomputer. The data acquisition and processing module detects the humidity of the formula soil through a humidity sensor, and converts the collected information into a signal and transmits it to the main control module to realize data transfer. The humidity sensor is installed in the formula soil to monitor the humidity of the soil in real time and transmit the data to the main control module. The humidity sensor can accurately detect the moisture content of the soil, thereby guiding the operation of the irrigation system to avoid excessive or insufficient irrigation. In the human-machine interface module, the staff can change and set different preset values ​​according to needs. The irrigation module uses a relay and is electrically connected to the first solenoid valve 10 and the second solenoid valve 16.

[0031] The main control module controls the opening and closing of the first solenoid valve 10 and the second solenoid valve 16 through the relay according to the set humidity preset value to realize automatic irrigation. In addition, water level gauges are installed in the water collection tank 15 and the water storage tank 8 to monitor water level changes and ensure the stable operation of the irrigation system.

[0032] Furthermore, water level gauges are provided on the water collection tank 15 and in the water storage tank 8 to ensure that the water in the water collection tank 15 will not overflow and that the water storage tank 8 will not be dry. Since the water storage tank 8 is connected to the water collection tank 15 through the connecting pipe 18, and the second water pump 17 and the second solenoid valve 16 are installed on the connecting pipe 18, when the water in the water collection tank 15 overflows or there is no water in the water storage tank 8, the main control module opens the second solenoid valve 16 and the second water pump 17 through the relay according to the water level to transport the water in the water collection tank 15 to the water storage tank 8, thereby ensuring the stable operation of the irrigation system and realizing the recycling of water.

[0033] As a preferred solution, a plurality of reinforcement members 7 are provided between the wall 1, the insulation layer 2 and the matrix layer 4. The reinforcement members 7 are integrated composite material rods. The reinforcement members 7 are seamlessly connected to the wall 1 to provide additional shear and bending strength, and increase the close fit between the wall 1, the insulation layer 2 and the matrix layer 4 in the structure.

[0034] The specific working process is as follows: when the main control module receives the humidity in the formula soil detected by the humidity sensor and the humidity is lower than the set humidity preset value, the main control module controls the relay to open the first solenoid valve 10 and the second water pump 17, and the water in the water tank 8 flows through the main pipe and the branch pipe, and irrigates the green plants through the nozzle 13.

[0035] In the present application, a temperature sensor may be further provided, and the main control module is connected to the temperature sensor at the same time. When the ambient temperature exceeds the preset temperature, the nozzle 13 also operates to cool down the ecological environment in the campus.

[0036] As above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
