Description
Technical field
The invention belongs to road construction technology, more particularly to reinforcing side slope technique.
Background technology
Slope reinforcement is that the need that can all run in the engineerings such as road, river channel, dyke and reservoir dam are located emphatically
The link of reason, to ensureing that engineering safety has very important effect.At present in engineering the mode of bank protection have multiple,
For example, riprap protection, block pitched work, gabion bank protection, block paving bank protection, Turf Culture plant etc..This
There is the shortcomings of many such as construction costs are high, maintenance maintenance is difficult in a little measures.Using microorganism to calcium and magnesium from
It is the new technique for occurring in recent years that the consolidation of son etc. carries out soil body antiseepage or reinforces, but which mainly lacks
Point is that antibacterial utilization rate is low, generation Calcium Carbonate nucleation is difficult and the adsorption rate on soil particle surface is low, seriously
Hinder the utilization and extention of the technology.
Content of the invention
Goal of the invention：For above-mentioned existing problem and shortage, it is an object of the invention to provide a kind of use
Liquid and its using method are reinforced in the low absorption enhancement mode microorganism for slope reinforcement of simple and convenient, investment.
Technical scheme：For achieving the above object, the present invention is employed the following technical solutions：One kind is used for side slope
Liquid is reinforced in the absorption enhancement mode microorganism of reinforcing, strengthens liquid and nutritional solution including antibacterial, absorption, and the antibacterial is
Bacillus cereuss, it is ferric ion solutions that the absorption strengthens liquid, the nutritional solution include carbamide, ionic calcium soln,
Nutriment and dissolved oxygen, wherein described nutriment are starch or glucose.
Preferably, the ferric ion solutions are ferric chloride in aqueous solution or ferrous chloride aqueous solution.
Preferably, the ferric ion solutions concentration is 1-1.5mol/L.
Preferably, the ionic calcium soln is calcium chloride water or calcium sulfate aqueous solution.
Preferably, the content of starch or glucose is 5～200mg/L in the nutritional solution, carbamide and calcium from
The mass concentration ratio of son is 1: 1～2.
The using method that liquid is reinforced in the microorganism is still further provides, being first will be native for ferric ion solutions injection side slope
Earth, after iron ion is fully mixed and stablizes some hours with soil particle, then microorganism reinforcing liquid is led to
The mode for crossing injection or spray is added in side slope soil.
Beneficial effect：Compared with prior art, the present invention has advantages below：Antibacterial utilization rate is increased substantially,
Calcium Carbonate nucleation adsorption efficiency increases, applied widely, and simple and convenient energy of constructing saves a large amount of construction investments, and
To Water table without destruction, very environmental protection.
Description of the drawings
Fig. 1 is the schematic diagram using pouring-in reinforcement means of the present invention；
Fig. 2 is the schematic diagram of employing fountain reinforcement means of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is further elucidated with, it should be understood that these embodiments are only used for
The present invention is described rather than limits the scope of the present invention, after the present invention has been read, those skilled in the art
The application claims limited range is fallen within to the modification of the various equivalent form of values of the present invention.
Biological consolidation phenomenon is microbial reproduction and a kind of natural phenomena in metabolic processes, is generally accompanied by
The biology of complexity, chemical process.The cardinal principle of the technology is, by injecting appropriate battalion in the soil body of underground
Foster material and mineral, excite the underground soil body or the bacterial activity in crack so as to amount reproduction.Some species
Antibacterial can produce a large amount of viscous liquids in reproductive process and be adsorbed on soil body granule, formed many cells
Polymer EPS (Extra-cellular polymeric substances), while accelerate water mineral deposition, warp
Can gradually solidify after a while and block the intergranular hole of the soil body, so as to reach the mesh for increasing soil strength
's.Due to pouring into underground after nutrient substance and subsoil water mixing, after water-bearing layer is entered, nutrient substance can be automatically
Follow the flowing of subsoil water and migrate, applied widely, construct simple and convenient.Underground reservoir is not produced brokenly
Bad, poisonous and harmful substance, very environmental protection will not be also produced, and substantial amounts of construction investment can be saved.In the technology,
Selected antibacterial is Bacillus pasteurii (Sporocarcina pasteurii), why selects the bacterium, is because
Compare with other class bacteroids, its hydrolysis ability to carbamide is higher.Nutrient solution used for carbamide, calcium preparation (bag
Include calcium chloride CaCl2, calcium sulfate CaSO4Deng soluble calcium solion), starch or glucose and molten
Solution oxygen etc..The effect of wherein carbamide is to produce carbanion for hydrolysis, to tie with the calcium ion in calcium preparation
Symphysis is into solid-state Calcium Carbonate；Starch or glucose and dissolved oxygen are for promoting bacterial reproduction to provide nutrient, and promote
Antibacterial produces cell aggregation thing EPS, increases solidification effect.Main Function mechanism is as follows：CO(NH2)2+
2H2O→CO3 2-+2NH4 +, then Ca2++2Cl-+CO3 2-→CaCO3↓+2NH4 +2Cl-.At present
The Main Bottleneck of this technology is that the utilization rate of antibacterial is low, generation Calcium Carbonate nucleation is difficult and is difficult in soil
Particle surface adsorbs.Therefore we carry out pretreatment from ferric ion solutions to soil particle, after measured, can carry
More than high bacterial adsorption rate 5-10%, accelerate deposition of the Calcium Carbonate on soil particle surface.
, used as bacteria concentrates, the iron chloride from 1-1.5mol/L is molten for Bacillus pasteurii first from culture
Liquid strengthens liquid as absorption, and the concentration range is drawn for test, too high, causes acid too strong, and antibacterial is difficult to give birth to
Deposit, too low then impact reinforced effects.Carbamide, calcium chloride and glucose are mixed to form after aqueous solution and are constantly blasted
Oxygen or air obtain nutritional solution, and the mass concentration ratio of wherein carbamide and calcium chloride is about 3: 5, glucose dense
Spend for 100mg/L.Reinforcing mode is divided to pouring-in reinforcing and fountain to reinforce two kinds, and pouring-in reinforcing is applied to side
Slope integral reinforcing, reinforcement depth depth；And fountain is reinforced and belongs to topsoil reinforcing.During practical operation, first slow
Injection ferric chloride solution so as to be fully contacted with soil particle surface, and stablize some hours, is then slowly noted
Enter bacillus cereuss concentrated solution, then slowly inject nutritional solution, injection rate can not be too fast, in case destruction soil is original
Structure.Result of the test shows that the technology is applied widely, and sand that various levels are matched somebody with somebody, loam side slope can be by
Its intensity improves 10%-50% or so, and cost is very cheap.
