Description

Technical Field

[0001] The utility model relates to the technical field of agricultural gardening and greening, in particular to a water system steep slope landscape stone cage bank protection. Background Art

[0002] Wire gabion is a kind of structure formed by galvanizing and magnesium-plating high-strength steel wire to prevent oxidation and wrapping soft and hard materials to form a box space, and injecting stones such as blocks and pebbles into the interior to connect. Its function is to provide structural support to ensure the stability of the slope and prevent landslides. It is widely used in many engineering construction fields because of its integrity, softness, durability, easy construction and combination, low cost, and anti-scouring. In the steep slope revetment of water systems, the traditional method of gabion retaining wall is: on the basis of the vertical stacking of square or rectangular boxes to form a slope protection structure, fine stones and silt are injected twice, and landscape treatment is formed by sowing plant seeds, adding planting pools on the top of the gabion, or reserving planting space in grades. However, the traditional slope protection method is the stacking of square or rectangular gabions. The vertical slope protection structure is easily displaced and deformed due to water erosion all year round, which poses certain safety hazards. In addition, the interface of the layered stacked revetment is rigid, and only relying on sowing seeds for greening, shallow soil planting or secondary addition of planting pools has poor landscape controllability and unstable box structure. At the same time, the secondary construction wastes manpower and equipment resources. In addition, the combination of traditional steep slope layered planting and wire gabion layered support requires more water and land, which wastes land resources, especially when the land space in the old city does not allow.

[0003] Prior art CN115450172A discloses a method for planting greenery on a gabion retaining wall. The method designs greening bags and pre-fills the greening bags in the gabions according to demand, thereby making the gabion wall connection closer and making the stones in the gabions more stable.

[0004] However, the gabion wall has the following problems:

[0005] (1) The direction of the plant gravity at the inclined planting method and the inclined angle position is a kind of oblique traction force, which does not coincide with the vertical support direction of the gabion slope protection and has a certain angle, which can easily cause the slope protection structure to be unstable. In particular, the larger the plant, the stronger the oblique gravity, which is more likely to affect the vertical retaining wall slope protection force.

[0006] (2) The surface of the planting soil is a slope, which is easily washed away during the rainy season, especially during the heavy rain season. The soil is easily lost, and the survival rate of seedlings is low, resulting in certain economic waste.

[0007] (3) The slope space is small and the soil is shallow, so only shrubs and vines can be planted. Larger plants such as small trees cannot be planted, and the landscape effect is difficult to control.

[0008] (4) The inlay pattern of soil bags and gabions is rather random, difficult to weave and troublesome to produce, which is not conducive to modular mass production in factories. At the same time, how to place them requires secondary construction design.

[0009] (5) Plant growth is excessively integrated with the gabion space, which can easily affect the gabion after a long time.

[0010] In view of the fact that the existing gabion revetment structure and slope protection effect are not ideal, and the adaptability to the steep slope of the water bank is weak, there is an urgent need for a water system steep slope landscape gabion revetment. Utility Model Content

[0016] As a further improvement of the utility model, the planting soil includes a bottommost pebble layer, on which a fine sand layer and a clay layer are laid in sequence from bottom to top.

[0017] As a further improvement of the present invention, the steel bars of the first gabion box extend downward to form anchor rods.

[0018] As a further improvement of the present invention, the length of the first gabion box is 200-250 cm, the width is 120-150 cm, and the height is 120-150 cm.
