[0019] Technical effects and advantages of the present application:

[0020] 1. Compared with the prior art, the anti-freezing ecological embankment structure suitable for high-cold inland areas preferably uses species that meet the cold resistance (survival temperature ≥-35°C) and adaptive root structure. For example, Picea crassifolia reduces the ice point of cells by anti-freezing protein to resist extreme low temperature, and its main root reaches a depth of 3-5 m. Cynomium relies on the underground stems of parasitic Nitraria tangutorum to store nutrients, and Haloxylon persicum uses widely distributed root systems to resist wind erosion and soil fixation, and Argyranthemum frutescens enhances cold resistance by cushion-shaped growth form. The configuration mode follows the principle of complementary ecological functions: the slope protection uses layered configuration, high shrubs (such as Picea crassifolia which can resist-35°C) form the main windproof layer, the middle layer is matched with herbaceous plants such as Argyranthemum frutescens with whole leaf, and the ground is covered with moss to build a gradient barrier; at the same time, through mixed seeding, Hippophae rhamnoides (nitrogen-fixing to improve soil), Agropyron cristatum (deep-rooted and drought-tolerant) and Saussurea (cold-resistant pioneer species) are combined to improve the stability and stress resistance of the community. In addition, combined with the regional characteristics, local species such as Elaeagnus angustifolia, Tamarix, and Populus euphratica which are resistant to salt and frost heaving can be used for riverbank protection or sand restoration, forming a multi-level and multi-functional vegetation system in cold and arid areas.

[0021] 2. Compared with the prior art, the anti-freezing ecological embankment structure suitable for high-cold inland areas uses multi-layer composite technology to consider seepage, frost resistance, erosion resistance and ecological functions: an anti-seepage layer is arranged at the bottom, which is composed of 2-5 mm particle size sandy soil mixture and geotextile (thickness 0.3-0.5 m), which guides water infiltration and inhibits frost heaving damage through pore permeation; a reinforcement layer is arranged on it, which is formed by staggered stacking of geotextile bags filled with gravel and freeze-thaw stabilizer (thickness 0.4-0.6 m), which enhances the stability of the embankment body against sliding; a wood pile and stone cage layer is arranged in the middle, which uses galvanized steel wire gabion net (mesh 8x10 cm) to wrap local stone to form a flexible facing, cooperates with wood piles with a spacing of 1.5-2 m to anchor and bind with the top of the stone cage, effectively resisting water erosion; an embankment system with cold resistance and erosion resistance is constructed.

[0022] 3、Compared with the prior art, the anti-freezing ecological embankment structure suitable for high-cold inland areas reduces the damage of frost heaving stress to the structure by mixing 10% to 15% expanded perlite and diatomite in the geotextile bag, and improves the durability by using pine wood preservative treated wood piles (buried depth ≥1.2m); ecological synergy relies on local plants to build ecological slope protection, fills planting soil with organic matter content ≥15% to optimize the habitat, and is equipped with a drip irrigation system (closed in winter to prevent frost cracking) to ensure the survival of vegetation all year round; the construction adaptability emphasizes the factory prefabrication and on-site modular assembly technology of stone cage units, reduces the difficulty of on-site operation, shortens the construction period by 40%, and takes into account the engineering efficiency and ecological resilience in the cold environment.
