Description
Technical field
The present invention relates to environmental protection and greening technique field, specifically a kind of slope vegetation protection method.
Background technology
Along with further developing of human society, environmental pollution and ecological disruption problem become one of human society urgent problem gradually.China is a developing country, wants to catch up with western developed country, must keep the good and fast development of economic construction.But the fast development emphasizing economy simply, easily ignores the protection of environment.In recent years, China's ecological disruption growed in intensity, so while maintenance rapid economic development; must take into account the sustainable development of ecotope, realize economic construction and environmental protection doulbe-sides' victory, this problem pole is by the attention of countries in the world; certainly, China is no exception.In the 21 century of rapid economic development, projects must get more and more, and also result in many problems, and this just requires that we will learn to go to deal with problems by the eye of the overall situation, and the doulbe-sides' victory of economic development and environment protection is only the optimal selection of projects.
China is a large agricultural country, rape is again one of main agricultural production crop of our country, what the whole nation was each has plantation, therefore, rape stalk is all usually that pile up like a mountain, how to process these stalks? in the rural area that some fall behind, rape stalk cannot process, a removing part is used as firewood, and the overwhelming majority is often all committed to the flames, directly burns.This not only result in flue dust and exists everywhere, and serious destroys ecotope, also wastes stalk resource.
According to investigations, the crude fiber content of some rape stalks is higher, and fibr tissue prosperity very, therefore it has larger tensile strength and stronger toughness, so this makes the process of rape stalk more difficult for.But this characteristic of rape stalk but can strengthen the performance of normal concrete.This test utilizes stalk fibre as admixture to prepare planting material, and object inquires into the correlated performance of stalk fibre concrete planting matrix.
In recent years, in order to realize all moderately well-off construction objects, China accelerated the step of economic construction, and particularly Developing west China needs Devoting Major Efforts To Developing, and the Party Central Committee has formulated strategy to develop western regions for this reason." want to get rich, first repair the roads." this proverb I believe everybody all what's frequently heard can be repeated in detail, so in the process implemented in strategy to develop western regions, large quantities of railway, highway is started building in succession.The thing followed is a lot of problems, and wherein water and soil loss problem is particularly serious.Along with assigning of State Council " about advancing the notice of national green channel further ", China's road construction has strided forward a new step, must pay attention to Road Greening Construction in road construction, realizes the coordinated development of road and environment and people.
But in the construction project of railway construction, highway, due to misoperation, very easily cause the destruction of ecotope, and these destroy very difficult reparation.Along with going into operation of construction project, massif excavates, fill out excavation misoperation, cause ground earth just directly outside exposed, the safeguard procedures that also there is no need, these exposed ground surface soil being exposed to the sun through burning sun, and the destruction of mankind's activity, become and very easily pulverize, more very easily avalanche under the effect of wind and current, cause water and soil loss, the whole nation is annual therefore and newly-increased water and soil loss area constantly increases.
These cause major part in the projects of water and soil loss is all due to the improper thus water and soil loss caused of side slope protection.In the process of project construction, the item cost accounting business of some evil minds is in order to as far as possible therefrom benefit, violence is taked to excavate during earthwork evacuation, give no thought to ecotope, and after earthwork evacuation, do not take due safeguard procedures, side slope protection process is usually subject to the ignorance of builder, and road more even does not unexpectedly take any slope protection measures in excavation process of construction, causes collapsing of side slope.
Under normal circumstances, in road construction, there is concrete code requirement to side slope protection, but actual, and slope protection measures is quite deficient, and the road slope even had does not carry out side slope protection.Now, side slope protection technology is also undeveloped, traditional slope protection measures many as spraying cement mortar, wipe one's face, build the modes such as sheet, but, these traditional bank protection modes there is great drawback and their ecological benefits are poor, cannot meet the requirement of ecotope; Certainly, nowadays still have some comparatively advanced bank protection modes, vegetative protection is exactly a kind of good mode.Traditional bank protection mode also exists huge restriction in environmental protection, and such as vegetation cannot grow in rock slope.Vegetation for where, rock slope cannot be survived, main cause have following some:
Rock slope is domatic smooth, soil cannot be attached to domatic on, plant lacks soil and nutrient, cannot plant greening.Domatic comparatively steep in rock slope, on domatic, lay turf or whitewashing, they also cannot with domatic bonding, do not have protection and effect attractive in appearance.Contained by rock, nutrient is low, and water retention capacity vegetation be difficult to therefrom draw nutrient to meet the needs of own growth.The gradient of general side slope is all excessive, is generally 1: 0.75, and the gradient even had is larger, can reach 1: 1.If rock slope is domatic too steep, in the area that southern rainfall is comparatively intensive, very easily forms normal erosion, cause water and soil loss; In high temperature area, side slope surface is too steep, domatic very easily by high temperature action, causes the erosion of rock, also very easily forms water and soil loss; In those arid areas comparatively, average annual rainfall is very little, if domatic too steep, rainfall cannot be stored in domatic on, vegetation is also difficult to growth.
Present stage, our side slope protection technology was very backward; the demand of ecotope cannot be met; traditional side slope technology has and there is huge drawback, but ecological environmental protection is very urgent again, and that just requires that we must find a kind of new side slope protection technology to solve these problems.Functional requirement below this new side slope protection technology demand fulfillment, specific requirement is as follows: one, this technology can meet the intensity of engineering and basic bank protection requirement; Two, the requirement of ecological environmental protection must also be met, in brief, the technology that greening vegetation and side slope protection effectively can be combined exactly.If there has been this technology, we just can reduce the cost of side slope protection under the prerequisite of protection of the environment, greatly improve expanding economy.

The bank protection substrate bricks material of embodiment 1-3 gained is carried out performance test, reference group be not cement but other component and operation gained identical with embodiment contrast bank protection substrate bricks material.How many performance tests is mainly distinguished with cement content, and contrast bank protection substrate bricks material cement content is 0%, embodiment 1-3 be followed successively by 10%, 15%, 20%; During planting experiment, plant seed sows 20g.
The brick material of gained in embodiment is carried out following test:
1) compression strength
Compression strength brick material is placed on pressure testing machine tests, and the model of testing machine is YAW-300B type, and stress rate is 0.08MPa/s, correction factor is 0.95, paint stress-strain diagram from computer and read peak value, read stress and compression strength, test result sees the following form.The bank protection substrate bricks material of each embodiment is prepared multiple, soaks and is respectively 7d, 14d and 28d the length of time.
The compression strength of the different cement content of table 1
7 days, 14 days intensity and 28 days intensity are compared, can draw the ratio between three, concrete numerical value is as table 4-2:
The ratio of table 2 each brick material 7d, 14d intensity and 28d intensity
α 7d/ α 28d=0.33 ~ 0.34 as shown in table 2, α 14d/ α 28d=0.57 ~ 0.73; Its mean compressive strength α 7d/ α 28d=0.34, α 14d/ α 28d=0.66.As can be seen here, brick material is 34% and 66% of brick material 28d compression strength in the compression strength of 7d, 14d.The compression strength α 14d of brick material 14d reaches more than 50% of 28d compression strength α 28d, illustrates that the early anti pressured intension of brick material is higher.Higher early anti pressured intension can ensure that ecological base material can not be loose, has good practicality.
2) impact of pH value
Modulation concentration is the Klorvess Liquid of 1mol/L, maintenance to the brick material in the length of time to be immersed in this solution 24 hours, then according to the mensuration specification of soil pH value, and the pH value of 10d, 15d, 20d when measuring kind of grass respectively and do not plant grass.
Measure the pH value of bank protection substrate bricks material when different cement content does not plant grass, the variation relation of bank protection substrate bricks material pH value and cement content can be known by let us, by surveying the pH value change of different time sections, the pH value relation over time of mixture can also be understood.And the contrast of bank protection substrate bricks material pH value, can also know the impact of kind of grass on bank protection substrate bricks material pH value during by planting grass and not planting grass.
The pH value of the different cement content planting matrix of table 4
When cement content increases, its pH value increases.When not adding cement, its pH value is 6.54, and after having added cement, the pH value of 10 days is all higher, is 8.06 ~ 8.97, and the pH value of 15 days is pH value after 7.95 ~ 8.13,20 days is 7.67 ~ 7.89.The visible growth along with the time, the pH value of bank protection substrate bricks material reduces gradually, is tending towards neutral.
As can be seen from Fig. 4-5, the pH value change of bank protection substrate bricks material after 10 days is the most remarkable, and the pH value change of 15 days and 20 days is not remarkable.When 10 days, because the bank protection substrate bricks material forming time is shorter, also unstable, so the acid-base value change of bank protection substrate bricks material is comparatively obvious; When 15 days and 20 days, bank protection substrate bricks material was through adjustment after a while, and its Acidity of Aikalinity is stablized gradually, and pH value is between 6.5 ~ 7.5, and this belongs to neutral scope.
Consult related data to find, pH value is neutral between 6.5 ~ 7.5,7.5 ~ 8.5 is alkalescent, when bank protection substrate bricks material places 20 days, its pH value is 7.67 ~ 7.89, now bank protection substrate bricks material is alkalescent, and this is conducive to the growth of majority of plant, and the excessive or alkaline mistake of soil acidity is mostly unfavorable for plant growth.
Measure the pH value of the rear different cement content bank protection substrate bricks material of kind of grass, in table 5, its pH value surveys 3 times, and the testing time is respectively 10d, 15d and 20d.By kind of grass with do not plant careless pH value comparative analysis, show that Fig. 4-7 is as follows:
Passing through kind of grass and do not plant grass comparative analysis, when cement content is 0, planting careless pH value than not planting the large of grass, closer to neutrality; When cement content is 10%, 15%, when 20%, plant the pH value of grass than not planting the little of grass, alkalescence is more weak.In conjunction with both, planting grass can adjust ph, makes it trend neutral, is beneficial to the growth of vegetation.
The pH value of different cement content bank protection substrate bricks material after table 5 kind of grass
3) growing state of grass
What careless growing state was mainly surveyed is coverage rate careless on bank protection substrate bricks material.
In order to carrying out smoothly of testing, will not add the sample of cement as benchmark, its coverage rate is 100%, is compared by other samples with it.The growing state of grass investigates 3 times, and the investigation time is respectively 5d, 10d and 15d.
Strain number × 100% of the strain number/blank sample unit are grass of coverage rate=sample unit are grass;
The growing state of grass is very important, and it is reflection Success in Experiment whether important indicator, and this experiment understands careless germination and upgrowth situation by the coverage rate measuring grass.
The growing state of the grass of table 6 different cement consumption bank protection substrate bricks material
The relation of table 7 bank protection substrate bricks material cement content and coverage rate
Can be learnt by experiment above, the growth of cement content to grass plays vital effect, and cement content is large, then the more difficult growth of grass, and the coverage rate of grass also and then declines thereupon.When cement content lower than 10% time, grass coverage rate all reach more than 85%; Cement content is 15% time, and the coverage rate of grass is respectively 68.6%, 70.8%, 71.6%; When cement content is 20% time, the coverage rate of grass is 53.5%, 55.1%, 60.2%, about now coverage rate reaches half, this has shown that the upgrowth situation of grass is not ideal, and the now surface lumps of bank protection substrate bricks material, grass turns to be yellow slightly, when this all illustrates that cement content reaches 20%, now not too be applicable to kind of a grass, so best cement content is 10 ~ 15%.
The above, it is only case study on implementation of the present invention, not any pro forma restriction is done to the present invention, therefore, every content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
