[0029] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, apparently, the described embodiment is only a part of the embodiment of the utility model, and is not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0031] It needs to be further explained that light filling layer 2 includes multiple stable layers 201 and multiple connecting layers 202, the upper and lower sides of each stable layer 201 are sprayed with connecting layer 202, the lowermost stable layer 201 is fixed with base layer 1 through connecting layer 202, the uppermost connecting layer 202 is fixed with protective layer 3, the overall weight of stable layer 201 is lighter, convenient to use, compared with concrete structure, light filling layer 2 only needs to pave stable layer 201 and then is fixed using connecting layer 202, installation is convenient, the overall weight is lighter, and the burden on base layer 1 is reduced.

[0032] In addition, each stable layer 201 is an EPS board, the EPS board can be replaced by XPS extruded board, but the density thereof must be less than or equal to 20kg / m³, and the thickness thereof is the same, the thickness of the EPS board is 50mm, each connecting layer 202 is an epoxy resin adhesive, the connecting layer 202 can be selected from other types of building adhesives, but must have good waterproof performance and adhesive force, the EPS board is convenient to carry and install, does not bring too large burden to the building structure, can be shaped by cutting, polishing and other ways, can better adapt to different actual conditions, does not produce harmful substances in the production process, and also does not produce smoke, peculiar smell and other pollutants in the use process, is harmless to human body and environment, the epoxy resin adhesive has excellent adhesive capacity for metal, plastic, ceramic and wood, has a wide range of applications, has good waterproof and moisture-proof performance, is conducive to application under wet conditions, can effectively prevent the erosion of water to the adhesive part, and is very suitable for providing connecting force for stable layer 201.

[0033] It can be known that the protective layer 3 is a high-strength protective net, the high-strength protective net is polyester fiber, the aperture of the high-strength protective net is 5mm*5mm, and the thickness is 2mm. In actual use, the tensile strength of the high-strength polyester fiber is excellent, can bear a larger tension without being easily broken, has a higher modulus, and has a relatively small degree of deformation when stressed, can better maintain the original shape and size, and provides reliable protection for application scenarios that require stable structural support. This makes the protective layer 3 able to provide more stable and reliable connecting force for the light filling layer 2. Whether in a dynamic environment frequently rubbed with the surface of other objects or a static environment subjected to external friction for a long time, the high-strength polyester fiber exhibits excellent wear resistance, so there is no need to worry about friction between the protective layer 3 and the light filling layer 2.

[0034] In the embodiment, a layer of geotextile can be additionally arranged under the stable layer 201 during actual installation to enhance the water-blocking effect, prevent water from penetrating into the base layer 1, and improve the stability of the structure. A layer of thin steel plate can also be additionally arranged above the protective layer 3 to improve the impact resistance of the structure, which is particularly suitable for flood-prone areas.

[0035] Please refer to Fig. 1 and Fig. 3 again. In order to improve the drainage effect, the covering layer 4 in the embodiment is earthwork, and a vegetation layer is arranged on the top of the covering layer 4, with a thickness of 30cm, to further enhance the stability and aesthetics of the structure. The plant species can be flexibly selected according to the climate and soil conditions of different regions. The drainage assembly 5 includes a plurality of water collection wells 501, a plurality of drainage pipes 502, and a plurality of well covers 503. The drainage pipe 502 has a diameter of 100mm. A water collection well 501 is arranged every 10m. The depth of the water collection well 501 is 1.5m. Each water collection well 501 is embedded in the covering layer 4. The plurality of water collection wells 501 are connected through the drainage pipes 502. The top of each water collection well 501 is fixed with a well cover 503 flush with the top of the covering layer 4. Subsequently, the water collection well 501 can be replaced with an intelligent monitoring system to monitor the drainage volume and water quality in real time, facilitating the timely discovery and handling of potential problems.

The connecting flange is used to provide stable connecting force for the drainage pipe 502 and the water collection well 501. Each drainage pipe 502 is fixed to the inner side wall of the water collection well 501 through the connecting flange.

[0037] In addition, the drainage pipe 502 on the far right side penetrates to the right side of the covering layer 4. The drainage pipe 502 can ensure that water can be smoothly discharged, while reducing the soil erosion caused by water flow. The top of the covering layer 4 is inclined, which is convenient for drainage.

[0039] In the embodiment, the drain pipe 502 can be made of HDPE material, but the diameter is kept consistent to ensure that the rainwater can flow quickly. After the vegetation layer is planted, it is necessary to regularly water and regularly check the survival of the vegetation to ensure that the unhealthy vegetation can be removed in time and the grip of the vegetation layer on the soil is ensured.

[0040] It can be understood that the use of the stable layer 201 and the connecting layer 202 can facilitate installation and reduce the burden on the base layer 1, thereby shortening the construction period, effectively reducing the impact on the surrounding environment, and facilitating subsequent maintenance.

[0041] The working principle of the above embodiment is as follows:

[0042] First, the base layer 1 is cleaned. After the base layer 1 is cleaned, the laying range and position of the lightweight filling layer 2 are determined by measuring and laying a line. The first stable layer 201 is laid, and the connecting layer 202 is used to connect it. The flatness and compactness of the first stable layer 201 are checked, and if there is unevenness or gap, it should be adjusted in time. The subsequent layers of the stable layer 201 are continuously laid until the designed height is reached. The protective layer 3 is laid on the surface of the stable layer 201, and the edges are fixed with anchor nails. The covering layer 4 is laid, and then the drainage assembly 5 is installed in the covering layer 4. The drainage assembly 5 is compacted by backfilling fine sand and crushed stone, and the plant layer is laid. Regular watering can be carried out.
