The microorganism reinforcing fluid has the advantages that the application range is wide, the construction is simple, convenience and fast, lots of engineering investment can be saved, the microorganism reinforcing fluid has no damage on an underground water layer and is very environment-friendly.
Description
?
Technical field
The invention belongs to road, water conservancy construction technology, relate in particular to reinforcing side slope technique.
Background technology
Slope reinforcement is the link that the need that in engineerings such as road, river channel, dyke and reservoir dam, all can run into are handled emphatically, to ensureing that engineering safety has very important effect.At present in the engineering mode of bank protection have multiple, for example, riprap protection, building block stone bank protection, gabion bank protection, block paving bank protection, Turf Culture plant etc.There are shortcomings such as many, maintenance maintenance difficulties high such as construction cost in these measures.
Summary of the invention
Goal of the invention:, the purpose of this invention is to provide a kind of easy to use, low mikrobe that is used for slope reinforcement of investment and add solid-liquid and method of use thereof to the problem and shortage of above-mentioned existing existence.
Technical scheme: for realizing the foregoing invention purpose; The present invention adopts following technical scheme: a kind of mikrobe that is used for slope reinforcement adds solid-liquid; Comprise bacterium and nutritive medium; Said bacterium is a genus bacillus, and said nutritive medium comprises urea, ionic calcium soln, nutriment and dissolved oxygen, and wherein said nutriment is starch or glucose.
As preferably, said ionic calcium soln is calcium chloride water or other solubility calcium salts solutions.
As preferably, the content of starch or glucose is 5～200mg/L in the said nutritive medium, and the mass concentration ratio of urea and calcium ion is 1:1～2.
The method of use that also provides this mikrobe to add solid-liquid in addition is that said mikrobe is added solid-liquid through injecting or the mode of spray joins side slope soil and gets final product.
Beneficial effect: compared with prior art, the present invention has the following advantages: consolidation effect is better, and is applied widely, and it is simple and convenient to construct, and can practice thrift a large amount of construction investments, and underground water layer is not had destruction, very environmental protection.

Fig. 2 is the synoptic diagram of employing spray-type reinforcement means according to the invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Biological fixed phenomenon is a kind of spontaneous phenomenon in microbial reproduction and the metabolic processes, is accompanied by complicated biology, chemical process usually.This technological cardinal principle is, through in the underground soil body, injecting an amount of nutritive substance and mineral substance, excites the bacterial activity in the underground soil body or the crack, makes its a large amount of breedings.The bacterium of some kinds can produce a large amount of viscous liquids and be adsorbed on the soil body particle in reproductive process; Form many cells polymkeric substance EPS (Extra-cellular polymeric substances); Quicken water mineral deposition simultaneously; Warp can solidify and stop up the intergranular hole of the soil body after a while gradually, thereby reaches the purpose that increases soil strength.Underground owing to pouring into after nutritive substance and the underground water mixing, after getting into the waterbearing stratum, nutritive substance can be followed phreatic flowing automatically and moved, and applied widely, it is simple and convenient to construct.Underground waterbearing stratum is not produced destruction, can not produce hazardous and noxious substances yet, very environmental protection, and can practice thrift a large amount of construction investments.In this technology, the bacterial species of being selected for use is a genus bacillus, why selects this bacterial classification, is that its hydrolysis ability to urea is higher because compare with other type bacteroid, and reinforcing takes shorter.Nutrient solution used is that urea, calcium agent (comprise calcium chloride CaCl
2Or other solubility calcium ions solution), starch or glucose and dissolved oxygen etc.Wherein the effect of urea is to be that hydrolysis produces carbanion, so that combines the solid-state lime carbonate of generation with calcium ion in the calcium agent; Starch or glucose and dissolved oxygen provide nutrient for the promotion bacterial reproduction, and impel bacterium to produce cell aggregation thing EPS, increase solidification effect.The main mechanism of action is as follows: CO (NH
2)
2+ 2H
2O → CO
3 2-+ 2NH
4 +, Ca then
2++ 2 Cl
-+ CO
3 2-→ CaCO

The genus bacillus of at first selecting cultivation for use is as the bacterium liquid concentrator; And urea, calcium chloride and glucose mixed to form constantly blast oxygen behind the aqueous solution or air obtains nutritive medium; Wherein the mass concentration ratio of urea and calcium chloride is about 3:5, and the concentration of glucose is 100mg/L.Reinforcing mode divides pouring-in reinforcing and spray-type to reinforce two kinds, and pouring-in reinforcing is applicable to the side slope integral reinforcing, and reinforcement depth is dark; And the spray-type reinforcing belongs to the veneer of soil reinforcing.
In this technology; The source of genus bacillus quasi-microorganism has two; At first be the genus bacillus liquid concentrator of cultivating through the injection experiments chamber, make that such microbe population sharply increases at short notice in the soil body, the starch in the nutritive medium, glucose and oxygen have also excited the growth of primary genus bacillus in the soil in addition; Make that the bacillus category microbial numbers can maintain higher level in the soil, so curing efficiency is higher.During actually operating, slowly inject the genus bacillus liquid concentrator earlier, slowly inject nutritive medium again, injection speed can not be too fast, in order to avoid destroy the soil original structure.Test-results shows that this technology is applied widely, all can its intensity be improved about 10%-50% the sand of various gratings, loam side slope, and cost is very cheap.
