Description
Technical field
The invention belongs to the Materials Science and Engineering field, be specifically related to a kind of material and application for the Gu Po greening.
Background technology
Bank protection refers to as preventing that side slope from being washed away, and the various general designations of paving and planting of doing on domatic comprise dyke strengthening flood control, grid bank protection, massif ecological recovery etc.
At first, dyke strengthening flood control is China's important process in every year always, and along with the development of national economy and the people raising to environmental requirement, the Ecological Construction of dykes and dams becomes people's common recognition day by day.At present the Gu Po of water bank has following several mode, and 1, stone is built by laying bricks or stones or the casting concrete plate, this way does not have greening function, and the globality that stone is built by laying bricks or stones is very poor; 2, use concrete net lattice beam Gu Po, the greening of banketing in grid, its afforestation effect is limited, and the ability of opposing flood is inadequate; 3, normal concrete Gu Po, reserving hole in concrete, greening in the cavity, diameter and the ratio in cavity are excessive, affect solid slope effect, diameter and the too small afforestation effect that affects of ratio in cavity.Highway, railway exceed the larger roadbed bank protection of ground level, basically use above-mentioned several mode, Gu Po and two effects of greening are difficult to get both.
Next is the bank protection that adopts for the massif that highway, railway bank are opened up when building the road, at present mainly use stone or normal concrete to carry out the grid bank protection in the part of soft clay, but revegetation is relatively poor, the rock part is substantially exposed, easily cause the natural calamities such as landslide, realize its greening and recover ecological significant.
The massif ecological recovery of various abandoned mines again.ecotope is the basis of human social economy's sustainable development, good ecology is one of necessary condition of human survival and life, mining makes the massif surface exposure, had a strong impact on ecotope, cause the ecosystem to suffer in various degree destruction, seriously restricted the sustainable development of human social economy, even jeopardize mankind itself's safety, therefore, ecological recovery has become the basic premise of mining, exposed massif after mining mainly adopts the mode of artificial planting trees to recover vegetation at present, but the time is long, and easily cause water and soil loss because of rain drop erosion.
Summary of the invention
The purpose of this invention is to provide a kind of material and application for the Gu Po greening, by scientific and reasonable composition and proportioning, to have the bank protection of certain mechanical strength, solid slope material combines with the phase with network structure, both can carry out maintenance to side slope, the root system of plant is grown in the material of solid slope, grow, realize that greening promotes its ecological recovery, has the characteristics of good integrity.
The technical solution adopted in the present invention:
A kind of material for the Gu Po greening, comprise framework material, pouring material and green material application, described framework material is formed by aggregate, Binder Materials, additive and water mixing, and wherein the parts by weight of each component are by weight: aggregate 800～1700, Binder Materials 160～210, additive 0.010～0.080, water 72～100; Described aggregate refers to build stone, haydite, slag or concrete disintegrating screening particle; Described Binder Materials refers to the Binder Materials of cement or alkali-slag system; Described additive refers to a class high molecular weight water soluble polymer, Binder Materials-water slurry body is under the prerequisite that this base polymer exists, when its water-cement ratio (weight ratio of water and Binder Materials) changes in a big way, the rheological behavior kept stable of slurry, the Typical Representative of this base polymer has: methylcellulose, cellulose ether, xanthans.Described pouring material is that its water-solid ratio (weight ratio of water and clay, fertilizer sum) is between 100:30～40 with the slurry of clay, nutritious fertilizer and water preparation.Described green material application is to be formed by clay, nutritious fertilizer and grass-seed mixing, and its weight ratio is: clay: nutritious fertilizer: grass-seed=100:0.5～30:0.5～1.5.
The particle diameter of described aggregate between 20～30mm, simple grain level grating.
Described cement refers to portland cement, Portland cement, pulverized fuel ash cement, pozzolan cement, slag cements or complex cement.
Described nutritious fertilizer refers to the conventional nutritious fertilizer that uses of agricultural or gardens.
Described grass-seed is the various grass-seeds that Landscape Industry uses.
The present invention also provides the application of a kind of above-mentioned solid slope green material application, and its concrete steps are as follows:
1, by proportioning, aggregate, Binder Materials, additive and water mixing are obtained framework material, then be layed in the engineering position (as side slope) that needs construction, thickness obtains having the skeleton of linked hole network structure at 10～15cm after condensing, its porosity is between 25～30%.
2, press proportioning with clay, nutritious fertilizer and water mixing, prepare the pulpous state pouring material, then be filled in the skeleton that condenses, have the linked hole network structure, sprinkle water maintenance after 14 days, more than its overall mechanical strength reaches 4MPa, form a relative closely knit solid slope material that is formed by hard skeleton structure and the soft network system.
3, by proportioning, clay, nutritious fertilizer and grass-seed mixing are obtained green material application, then be routed to the surface of the solid slope material that framework material after condensing and pouring material form, thickness is 1～3cm, and the maintenance of sprinkling water, until root system of plant penetrates solid slope material.
For the greening of bare rock, can lay in advance at rock surface the argillic horizon of 10-15cm, construct by above-mentioned engineering method again after compacting.For the gradient more greatly, highly higher rock, can put muscle on rock, tie up when laying solid slope green material application and put horizontal bar.
For the Gu Pos greening of the gradient greater than 60 degree, can when skeleton structure is in the milk, grass-seed be sneaked into slurry, the watering maintenance.
A kind of material and application for the Gu Po greening provided by the invention, its advantage is: 1, material monolithic large tracts of land laying, whole sclerosis, Gu the slope globality is strong, due to the protection of networking sclerotic bone shelf structure, Gu the anti-flood erosion of slope material, Gu Po, protection effect are good; 2, owing to having the network system that is fit to plant growth in material, Gu the slope material surface can be obtained good afforestation effect, existing solid slope mode can not be compared; 3, for tall and big, precipitous rock greening, by bar planting in rock, in the solid slope material that the colligation horizontal bar solidifies, security performance is high; 4, have wide range of applications, can be widely used in the Gu Po greening of water (river, lake, ocean) bank, highway and railway bed, the ecological recovery of highway and railway both sides bare rock, abandoned mine.
