Problems solved by technology

[0004] The existing road slopes adopt chemical and mechanical sand fixation, but after long-term use of mechanical sand fixation, it is easy to be buried by sand, thus losing the effect of sand resistance and sand fixation, and chemical sand fixation will inevitably have some impact on ecology

Embodiment 1

[0051] A soil-fixing system for vegetation on desert highway slopes, the soil-fixing system can be applied to excavated highway slopes and filled highway slopes, such as Figure 1A As shown in the figure, the soil-fixing system is formed by splicing a plurality of soil-fixing modules, and each of the soil-fixing modules includes a grid soil-fixing plate 1 with a planting opening 4 in the center and a soil-fixing plate 1 fixed at the bottom of the grid soil-fixing plate 1 The soil basket 2, the upper surface of the soil fixing basket 1 is inclined, so that the grid soil fixing plate 1 and the horizontal plane form the same angle as the slope of the excavation road and the filling road. 2 includes a circumferentially arranged basket wall and a basket tube fixed on the bottom opening of the basket wall, and the top opening of the soil fixing basket 2 is butted with the planting port 4 .

[0052] The soil-fixing system also includes a fixed pile 3, which is fixed on the grid soil-...

Embodiment 2

[0062] On the basis of Example 1, in order to further increase the survival rate of plants, the desert road slope vegetation soil-fixing system further includes a drip irrigation module, which includes a watering truck, a drip irrigation pump and a drip irrigation pipeline 16. The drip irrigation module can be used to On the basis of using the least water resources, the maximum plant survival rate is guaranteed. The dropper module supplies water in the early stage, and the plants rely on natural conditions to survive in the later stage.

[0063] The soil fixing basket 2 is also provided with a pipe hole 8 for the drip irrigation pipe 16 to pass through. Specifically, after the soil fixing basket 2 is installed, the pipe is passed through the pipe hole 8 and plants are planted in the soil fixing basket 2 , add nutrient soil. Each row of soil-fixing modules shares a drip irrigation pipeline 16, and the drip irrigation pipeline 16 is provided with permeable holes, and the permeab...

Embodiment 3

[0069] A soil-fixing basket 2 based on Example 1, wherein a water-collecting holder 9 is further provided in the soil-fixing basket 2, the water-collecting holder 9 is made of degradable material, and the bottom of the water-collecting holder 9 is hemispherical to gather The water reaches the lowest end of the plant root, the water collecting receptacle 9 is provided with an inner through hole 17 for the primary drip irrigation pipe to pass through, and the soil fixing basket 2 is provided with an outer through hole 18 for the primary drip irrigation pipe to pass through. The inner through hole 17 of the The length is 35-50% of the length of the soil-fixing basket 2, and the thickness of the water-collecting support 9 is 35-60% of the thickness of the soil-fixing basket 2. When degraded, the water collecting support 9 is preferentially degraded. Give the plant root space for the first time, and then the degradable board 10 degrades, so that the plant can take root completely. ...

Abstract

The invention discloses a desert road slope vegetation soil fixation system and a soil fixation method.The soil fixation system is formed by splicing a plurality of soil fixation modules, each soil fixation module comprises a grating soil fixation plate with a planting opening in the center and a soil fixation basket fixed to the bottom of the grating soil fixation plate, and the soil fixation system further comprises a fixing pile; and the fixing piles are fixed on the fixing plates on the edge of the system. Due to the arrangement of the grating soil fixing plates, the soil fixing baskets and the plants, the stability of the roadbed can be protected, the effects of wind prevention and sand fixation can be achieved, fertilizer and microorganisms can be provided for soil through nutrient soil, the local environment of the soil is improved, and the plants can restore the ecological environment. Therefore, the desert road maintenance method is a desert road maintenance technology integrating multiple functions of preventing wind erosion, improving local soil environment, recovering vegetation and the like.

Description

technical field [0001] The invention relates to the technical field of desert sand-fixing, in particular to a soil-fixing system and a soil-fixing method for desert highway side slope vegetation. Background technique [0002] my country is the country with the largest desertification area in the world. The climate in desert areas is dry, the precipitation is scarce, the sandstorms are frequent and the sand sources are difficult to control. Therefore, the infrastructures such as railways in desert areas are affected by sandstorms to varying degrees. A major problem in building roads in deserts is sandstorms. Influence, the sand will be blown onto the road under the action of the wind, which will not only cause the friction of the road surface to decrease, affect the driving safety, but also may bury the road. [0003] At present, the existing sand fixation technologies mainly include: mechanical sand fixation, chemical sand fixation and biological sand fixation. The mechanica...
