Description

technical field [0001] The invention relates to a manufacturing device for a vegetation belt for ecological slope protection, which is mainly used for producing a vegetation belt for slope protection and belongs to the field of environmental geotechnical engineering. Background technique [0002] Ecological restoration and soil and water conservation projects are national key projects. With the rapid development of the economy, a large number of infrastructures such as highways and railways have been built. The construction of these infrastructures has destroyed the surface ecology, resulting in a large number of exposed rock and soil slopes to be repaired. Usually, slopes with good soil quality can be directly restored by planting grass; while high and steep rock slopes have the characteristics of steep slope, poor soil quality and difficult construction, and its ecological restoration is an engineering problem to be solved. [0003] At present, there are mainly two types ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly two types of ecological slope protection methods: one is grass-irrigation transplantation method, and its disadvantage is that pits must be dug for transplantation, and pits destroy the original edge. The stable structure of the slope is likely to cause collapse under rainfall erosion, which affects the stability of the slope; digging pits damages the surface of the slope, which is likely to cause water and soil loss on the surface of the slope; the cost of digging pits, purchasing seedlings, and maintenance is high

Its disadvantages are: thick-layer substrate spraying greening is to fix the three-dimensional mesh or metal mesh on the slope after slope cleaning, and then spray the substrate containing seeds onto the slope fixed by the three-dimensional mesh or metal mesh. Under some special working conditions, this method is difficult to construct and the cost is high. The substrate is connected with the three-dimensional mesh or metal mesh by adhesive. The effect of the adhesive is limited and it is easy to cause the entire substrate to slip; For slopes with good soil quality, it is not suitable for high and steep slopes with poor soil quality

[0004]The newly emerging vegetation zone slope protection is mainly used on gentle slopes with small slopes, and its structural functions cannot meet the ecological restoration of high and steep rock slopes

Such as: non-woven adhesive lawn vegetation belt, which has poor foldability and transportation resistance, and is only suitable for laying gentle slope lawns; the traditional method of stacking soil in vegetation bags is complex in construction, high in cost and has potential safety hazards; Combined planting belt, the production equipment has complex structure, long process flow, inconvenient operation and actual engineering construction; rolling needle-punched planting belt, the production device is too complicated, the production process is long and the operation is cumbersome

The structural defects of these vegetation belts and the complexity of manufacturing equipment are not suitable for ecological protection projects on high and steep rock slopes.
