Abstract
The invention discloses the method for reinforcing accumulation body side using microbial mineralization effect, and the mineralization product of microorganism can be utilized to realize the filling in accumulation body slope accumulation material space.The intensity and integrality of accumulation body slope accumulation material can be strengthened, strengthen the local stability and resistance to overturning of accumulation body slope.
Description
Technical field
The present invention is a kind of method that accumulation body slope microbial mineralization effect is reinforced, and belongs to side slope or accumulation body slope adds
Gu field.
Background technology
Accumulation body slope is relatively conventional in construction of hydropower plant nodal region and reservoir area.Typically just amount is big for accumulation body slope, surely
Qualitative difference, its stability of engineering construction phase is very big to main structures security implication, if producing landslide after reservoir filling, can produce
Very big surge, there is very big hidden danger safely to hydraulic structure.And the accumulation body slope in flood-discharge atomizing area is also to engineering
Potential safety hazard be present in safe operation.Accumulation body slope security is generally speaking significant for engineering, according to traditional improvement side
Method, accumulation body slope mainly take friction pile to carry out supporting, while are aided with the measures such as concrete patch slope, prestress anchorage cable, draining,
But friction pile typically requires that the depth for going deep into basement rock is larger, and when side slope sliding force is larger, friction pile section is bigger, enters rock depth
Deeper, difficulty of construction is very big, and construction time security risk is larger, and construction period fraction is relatively low, and consolidation effect have it is to be tested.
Consolidation process is carried out to rickle using microbial mineralization effect, is a kind of reinforcement technique of innovation.The skill
The cardinal principle of art is, by injecting the mixed solution of appropriate microorganism and nutrient solution into accumulation material, using certain slightly
Catalytic action hydrolysis generation carbanion of the biology to urea, and mineral deposit is produced with calcium binding, gradually solidification
And rock cranny is bonded, so as to reach the purpose for being bonded and increasing accumulation material intensity and globality.
The content of the invention
The present invention reinforces problem for accumulation body slope, using the microorganism reinforcement means of novelty, establishes a set of new
The method flow of accumulation body slope is reinforced in microbial mineralization effect.
The present invention adopts the following technical scheme that:
1. making microorganism mixed solution pours into pipe.
2. ectogenesis is suitable for the microorganism (Bacillus pasteurii) of accumulation body slope accumulation material, and configures nutrition
Liquid.
3. the position of local stability difference and crucial reinforcing position in selected accumulation body slope, and buried at its low elevation position
If drainpipe, microorganism mixed solution intrusion pipe by certain row's spacing insertion accumulation body slope.
4. microorganism and nutrient solution mixed solution are injected toward the microorganism mixed solution perfusion mouth of pipe, under treating that liquid level is no longer in pipe
Stop pouring into during drop.
5. treat that solution dries up in microorganism mixed solution intrusion pipe, penetration concrete mortar closed conduct.
The invention has the advantages that:
1. it is covered with the microorganism mixed solution intrusion pipe of aperture using pipe shaft so that microorganism and nutrient solution mixed solution energy
Uniformly it is diffused on accumulation body slope, and reduces the interference of deposit confrontation fill orifice on accumulation body slope.
2. setting drainpipe at the low elevation position in intrusion pipe periphery, avoid because the effect of solution water make it that accumulation body slope is steady
Qualitative variation.
3. intrusion pipe periphery microbial mineralization acts on a range of loosely-packed material is bonded together, strengthened
The intensity of accumulation body slope and the integrality with side slope material, and improve the stability of accumulation body slope.
4. arrangement intrusion pipe on a large scale, friction pile and the reinforcement effect of anchor tie plate combination can be played, strengthens the whole of side slope
Body stability.
5. reinforcement means is simple and efficient, lower cost for material.
Brief description of the drawings:
Fig. 1 is that microorganism mixed solution pours into pipe elevation.
Fig. 2 is schematic diagram before accumulation body slope is reinforced.
Fig. 3 is accumulation body slope microorganism reinforcement means schematic diagram.
In Fig. 3:1, accumulation body slope material;2, drainpipe;3, microorganism mixed solution pours into pipe;4, microorganism and nutrition
Liquid mixed solution;5, microbial mineralization acts on filling of the product in accumulation material space.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
The present invention rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are each to the present invention's
The modification of the kind equivalent form of value falls within the application appended claims limited range.
1. according to the geology orographic condition of accumulation body slope, the tentatively selected poor position of slope stability and needs are added
Solid position.
2. according to accumulation body slope substance characteristics, selection is suitable for the species for adhering to its surface microorganism, carries out extensive
Ectogenesis, and configure the nutrient solution adapted to it.
3. it is covered with the thin gauge conduit of aperture, the note irrigated as microorganism and nutrient solution mixed solution according to Fig. 1 making pipe shafts
Enter pipe.
4. the emphasis determined by step 1 reinforces position, position and the row's spacing of fill orifice are rationally designed, one by one by intrusion pipe
Insert inside accumulation body slope, and a series of drainpipes are set at intrusion pipe periphery bottom elevation position.
5. the mixed solution of microorganism and nutrient solution is injected into intrusion pipe, until the liquid level no longer side of decline stops in intrusion pipe
Only primer solution.
6. sampling inspection microbial mineralization acts on filling situation of the product to accumulation body slope space, as filling situation is paid no attention to
Think, on its periphery, arrangement new bore re-starts perfusion.
7. treating that solution dries up in intrusion pipe, concrete mortar is injected, closes intrusion pipe.
8. sampling inspection is all qualified, accumulation body slope, which is reinforced, to be terminated.
