Earthwork standard room revetment applicable to plateau saline soil

Abstract

The invention relates to an earthwork standard room revetment applicable to plateau saline soil. The earthwork standard room revetment comprises earthwork standard rooms, an ecological revetment base material and revetment plants. Each earthwork standard room is a honeycomb earthwork standard room, extends and contracts freely and is of an excellent durable space structure. Holes are uniformly distributed in each earthwork standard room. Each earthwork standard room is made of a high-density polyethylene material, an anti-saline compound additive is added for modifying the earthwork standard rooms, and the excellent salt resistance, cold resistance and chemical stability are achieved; the ecological revetment base material is formed by mixing the saline, an organic curing agent and organic fiber according to certain proportion, and the durability, scouring resistance and the freeze-thaw effect in the saline environment can be improved; by the adoption of the earthwork standard room revetment applicable to the plateau saline soil, the defects of the ecological revetment in the plain area are overcome, the bad condition in the high-cold and high-altitude region can be resisted, the salt and alkali corrosion resistance, strong ultrasonic ray resistance and hydraulic scouring resistance are achieved, the cost is low, no secondary pollution exists, and the ecological environment of the water source of the three-river-source region can be kept with the earthwork standard room revetment as the ecological revetment of the plateau saline soil.

Description

technical field [0001] The invention relates to a geocell revetment suitable for plateau saline soil and belongs to the field of ecological restoration. Background technique [0002] Saline soil is the general term for saline soil, alkaline soil and various salinized and alkaline soils. It is widely distributed all over the world. The saline soil in my country is concentrated in the northwest, north China and eastern coastal areas. Among them, the western region has a total of saline soil 2 506.33×10 4 hm 2 , accounting for 69.03% of the total saline soil area in the country. Most of the terrain in northwestern my country is a plateau, among which the Qinghai-Tibet Plateau is the largest plateau in China and the highest in the world, known as the "roof of the world". The Qinghai-Tibet Plateau has high altitude, large temperature difference, strong radiation, drought, little rain, windy, high wind speed, low oxygen content, and severe freeze-thaw cycles. The area of ​​salt...

Problems solved by technology

[0004] While regulating the river, it is also necessary to improve the landscape on both sides of the river. At present, domestic hard bank revetment mainly adopts techniques such as hanging net spraying podcasting soil and greening grass bags. The process is relatively complicated, the demand for labor is large, and the stability of bank revetment is relatively weak

Moreover, the existing ecological revetment technology is only suitable for plain areas, and cannot adapt to the characteristics of high cold, high salinity, and strong ultraviolet rays in plateau high-altitude areas, and cannot protect the river ecology in plateau areas. Therefore, it is necessary to propose a method suitable for Ecological revetment of plateau saline soil
