Description
Technical field
The invention belongs to abrupt slope massif slope vegetation ecological protection and road traffic engineering security fields, particularly relate to a kind of abrupt slope massif slope vegetation ecological protection construction method.
Background technology
Preserve the ecological environment, promote socioeconomic health, sustainable development, become the common recognition of countries in the world and the task of facing.In recent years, with the quickening of large-scale development of China's western region paces, there is increasing massif excavation, and produced serious ecological disruption.Rationally, the research and apply of effective slope vegetation protection engineering reproduces the good ecological environment of China, builds green channel, ensure traffic main artery unimpeded in the urgent need to.
Karst is the distinctive landforms phenomenon in carbonate rock distribution area, the slope vegetation protection method of side slope single at present has turfing bank protection, tape planting bank protection, hydraulic sprinkle grass planting bank protection, three-dimension vegetative net bank protection, Vetiver grass hedgerow bank protection etc., also has traditional alien earth sparging technique, said method can not from the basic massif soil structure solving karst, soil compactness, hardness, the problem of globality, cause side slope higher, steeper, this cumulative stress is just larger, the lateral pressure that the bank protection of process bears is also larger, and occur with rainfall, a large amount of soil erosion, vegetation deterioration, just easier to be damaged, to collapse cunning, endanger huge.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of abrupt slope massif slope vegetation ecological protection construction method is provided.
Technical scheme of the present invention is summarized as follows:
A kind of abrupt slope massif slope vegetation ecological protection construction method, comprises the steps:
(1) be that 8-12m place arranges catchwater in the corresponding vertical line interval height that abrupt slope massif is domatic, between neighbouring two catchwaters, be provided with sluicing recessed channel or gutter;
(2) the domatic caducous float stone of abrupt slope massif is cleared up, domatic with the abrupt slope massif after water-wet cleaning, the green phytyl matter of restoration of the ecosystem being used for abrupt slope reinforcing is added water and is made into slurries, spray abrupt slope massif domatic;
(3) anchor pole is fixed on abrupt slope massif domatic, greener component cage of planting is fixed on anchor pole; Grid and steel rope net is set gradually green planting on component;
(4) add water and be made into slurries with being used for restoration of the ecosystem green phytyl matter that abrupt slope reinforces and spray that to be provided with green abrupt slope massif of planting component cage, grid and steel rope net domatic.
The restoration of the ecosystem green phytyl matter of reinforcing for abrupt slope makes by following method:
1) by weight, by low alkali sulphate aluminium cement 5-15 part, particle diameter is 5-20 object perlite 5-20 part, turfy soil 5-40 part, monkey grass 5-10 part, active silica 5-10 part, and Lauxite 5-10 part mixes and obtains A;
2) by dichlorotetra-fluoroethane 8-20 part, gelatine powder 2-8 part, the 10-30 part that adds water mixes and obtains B;
3) turfy soil 8-10 part is joined in polyvinyl alcohol 5-8 part to mix obtain slurries, by the seed 15-40 part chosen, join in slurries to mix and obtain C;
4) A and C is mixed to obtain mixture;
5) by B and step 4) mixture that obtains mixes the green phytyl matter of restoration of the ecosystem obtaining reinforcing for abrupt slope.
Described seed is preferably tall fescue seed, ryegrass seed, alfalfa seed, Indigofera amblyantha, Robinia pseudoacacia Seeds or Bermuda grass seed.
Green component cage of planting makes by following method:
1) will the construction work discarded object of metal and timber be removed, and rinse and obtain by screening, cutting, levigate, water the particle that particle diameter is 0.5-4 μm, dry;
2) by weight, by quick hardening sulphoaluminate cement 5-30 part, flyash 5-15 part, humus soil 15-60 part, particle 5-10 part that step (1) obtains, carbon black 1-4 part, mixing and stirring obtains A; Again by Animal Bone rubber powder 1-4 part, water reducing agent 5-8 part, polyvinyl alcohol 0.5-2 part, cellulose ether 0.5-2 part, polypropylene fibre 0.05-1 part, sodium acid carbonate 0.5-10 part mixes and obtains B;
3) B and A is mixed, add the water of B and A gross weight 15%-30%, pour in element mold, reaction, obtain greenly planting component, load in metal cage, make and greenly plant component cage.
Of the present invention method is simple, effectively can solve the ecological recovery problem of high steep bare rock slope.By the laying of the green component of ecological solid waste, the green component of ecological solid waste and massif is made to combine closely integral, utilize the special construction of the green component of ecological solid waste, space and the nutriment of growth are fully provided to plant, and can effectively prevent erosion, utilize vegetation to reinforce to reach maximum and afforest the object of massif.For preserving the ecological environment; the massif slope vegetation that recovery roadside and other engineering construction damage, eliminates road traffic engineering hidden danger, guarantees project delivery method; alleviate or avoid the generation of side slope damaged or destroyed by flood accident, to raising economic and social benefit, all there is very positive meaning.
The present invention makes full use of construction work discarded object, environmental protection, is applicable to plant growth.Coordinate the actual conditions of massif to reinforce and combine the alien earth sparging technique of improvement, there is more effective water retention, nutrient preserving capability, have again water permeability, gas permeability, maximum growing space can be provided to plant and Nutrient medium required for growing.The present invention is applicable to the abrupt slope massif ecological revetment of more than 70 °.
