Description

Technical Field

[0001] The present invention relates to the technical field of spliced ecological revetments, and particularly to a combined spliced ecological revetment for plateau permafrost and a construction method thereof. Background Art

[0002] Plateau permafrost in the Qinghai-Tibet Plateau refers to various rocks and soils with ice below zero degrees Celsius; generally, it can be divided into short-term permafrost, seasonal permafrost, and multi-year permafrost; the areas of multi-year permafrost, seasonal permafrost, and short-term permafrost zones on the earth account for about 50% of the land area, among which the multi-year permafrost area accounts for 25% of the land area; permafrost is a soil medium extremely sensitive to temperature, containing abundant underground ice. Therefore, permafrost has rheological properties, and its long-term strength is much lower than the instantaneous strength characteristics. Due to these characteristics, when constructing engineering structures in permafrost areas, two major hazards must be faced: frost heaving and thaw settlement.

[0003] As is well known, the higher the altitude, the more fragile the ecological environment; in recent years, in order to protect the ecological environment in plateau areas, people's environmental protection awareness has gradually increased; during the ecological protection of rivers in permafrost areas, ecological revetments usually need to be set on both sides of the riverbanks, using plants or a combination of plants and civil engineering to protect the river channel slopes; ecological revetments integrate flood control effects, ecological effects, landscape effects, and self-purification effects, enabling the river water and soil to infiltrate each other and enhancing the self-purification ability of the river channel; due to the frost heaving and thaw settlement problems in permafrost areas, the ecological revetments provided by the existing technologies often have poor adaptability. After the soil surface changes, the upper protection structure often collapses and loses its protection function, resulting in a short protection time; therefore, an ecological revetment technology suitable for plateau permafrost areas is needed. Summary of the Invention

[0004] The technical problem solved by the present invention is: to provide an ecological revetment structure suitable for plateau permafrost areas, which can achieve effective ecological protection functions, is easy to implement, and has strong practicability.
