Description
Technical field
The present invention relates to a kind of particularly speedway of ecological revetment engineering that is applied to, the ecological revetment technology that railway is used, emphasis is the construction method of slope protection substrate.
Background technology
For the importance of the ecological revetment of speedway, people are understanding to some extent basically.The ecological protection engineering of present domestic highway is seen everywhere.But the bank protection Failure cases is also a lot of in the ecological revetment of speedway at home, and particularly the gradient is bigger, arid or semiarid zone, supply such as the moisture of side slope, nutrient is relatively poor, under nature, the lawn occurs and degenerates, domatic collapsing, the situation of peeling off takes place often.Especially utilize the alien earth sparging technology to carry out the domatic of ecological revetment and collapse, it is more frequent that the situation of peeling off occurs, even the gradient is very slow, one runs into heavy rain, and soil moisture content increases, and is easy to cause local little landslide.Cause the main cause of the ecological revetment failure of speedway to be summarised as following 2 points:
One of reason:, be unfavorable for that plant grows chronically by the soil depletion of excavation slope.Though the soil moved in to improve the original layer has certain fertility and soil activation, the soil moved in to improve the original layer is thinner, and the ability of supplying with nutrient and fertilizer is very limited, and the fertilizer of short-term can only be provided at most, is unfavorable for that the long term growth of vegetation is grown.The root of vegetation has to fertilizer, does not go so root temporarily can not be deep in the immature soil, goes in the shallow-layer soil moved in to improve the original around only can going into, and only just can go deep into sloping body inside to immature soil activation back root.So in the previous stage of ecological revetment engineering, the degree of depth that root gos deep into soil only limits to objective the thickness of the layer basically, only be distributed in the top layer of soil, do not have due anchorage effect, and why vegetation is used for bank protection is exactly to utilize reinforcement and the anchorage effect of vegetation root to soil, in case this reinforcement and anchorage effect to soil lost, slope vegetation protection must be failed.
Former therefore two: soil moved in to improve the original layer and not enough by the domatic cohesion of excavation slope, soil moved in to improve the original and domatic between frictional resistance also little.Soil moved in to improve the original and domatic very vivid the saying of relation are exactly " two skins ".Like this, when running into company's rainy day gas, rain penetration is to inside soil body, cause acting on hydrodynamic load on the soil body and hydrostatic load and uprush simultaneously that soil shear strength reduces, the side slope moisture content increases, and has produced certain seepage force, also has gravity also to increase along the component of line of slope.Acting in conjunction in these factors is very unfavorable to stablizing of sloping body, causes little landslide phenomenon often to take place.
Summary of the invention
The purpose of this invention is to provide a kind of being implemented on the side slope of the gradient less than 50 degree, can change the present situation and the vegetation growth environment of soil depletion, the fertilizer and the nutriment of necessity are provided for the sustainable growth of plant, can increase simultaneously the soil moved in to improve the original layer again greatly and be broken the cohesion of face and the resistance to overturning of substrate layer, effectively stop the novel ecological slope protection substrate building method that continues the sliding rupture in whole or in part of domatic (together with vegetation on it) under the rainwater effect by excavation.
The object of the present invention is achieved like this: a kind of novel ecological slope protection substrate building method, after the slope leveling that needs are repaired, on domatic, excavate degree of lip-rounding hole earlier, and in degree of lip-rounding hole, fill multifunction soil, finish constructing of slope protection substrate.Described multifunction soil is the mixture by planting soil, urea, fertilizer and depot fertilizer, in heavy part: planting soil 1, urea 0.01-0.03, fertilizer 0.1-0.2 and depot fertilizer 0.04-0.06.
Fertilizer is selected straw or human and animal excreta for use.
Depot fertilizer is selected urea aldehydes fertilizer for use.
Novel ecological slope protection substrate building method provided by the invention has the following advantages:
1, the setting in " degree of lip-rounding hole " makes the soil moved in to improve the original layer and is strengthened greatly by the cohesion of the broken face of excavation, the soil moved in to improve the original layer by " degree of lip-rounding hole " be embedded in domatic on, the effect in " degree of lip-rounding hole " just as nail substrate layer be fixed on domatic on.Compare with traditional base material arrangement, the stability of soil moved in to improve the original layer integral body has had significant raising.Can effectively stop the integral slipping that continues domatic part (together with vegetation on it) under the rainwater effect to destroy.
2, the setting in " degree of lip-rounding hole " has changed the present situation of conventional method soil depletion greatly.Fertilizer in each " degree of lip-rounding hole " all is enough to keep for a long time its interior vegetation growth of 600mm scope on every side.The high planting soil of activation degree is not only arranged in the hole, and having organic fertilizer, organic fertilizer to contain abundant organic matter and various nutrient, it not only can directly provide nutrient for crop, and the potential nutrient in can activating soil, strengthen microbial activity, promote material to transform organic fertilizer, can also improve soil physical and chemical property, increase soil fertility, the control soil pollution, this is that chemical fertilizer is not available.Depot fertilizer adopts urea aldehydes fertilizer, and what can continue provides vegetation required fertilizer, guarantees the lasting growth of vegetation.
3, the setting in " degree of lip-rounding hole " increases the growing space of vegetation root system greatly, and this helps the g and D of vegetation root system.Because the root of plant has to fertilizer, they are always grown towards the place of growth conditions " superior ", so undoubtedly the setting in " degree of lip-rounding hole " has promoted the growth of vegetation root system greatly, thereby the performance root system is to the anchoring reinforced action and the water and soil conservation function of soil.
4, the present technique construction cost is low, and through calculating, the setting in " degree of lip-rounding hole " makes " every 100m
2Domatic amount of excavation only increase by 0.4 cubic metre, fertilizer also is very cheap, the consumption of urea is also fewer, so measure is for very little of the influence of engineering cost.
5, the phase neighbours' two row degree of lip-roundings holes being staggered on domatic, make domatic stressed more balanced, also helpful to the stability that improves soil moved in to improve the original layer integral body.
