A kind of tunnel blind pipe Crystallization Plugging scavenger, preferred plan is, by the material composition of following mass percent,
Formic acid 30%, citric acid 15%, V98 thickened lubricant 1.5%, water 53.5%.
Carbonate, the sulfate, calcium phosphate precipitation that the blocking of tunnel blind pipe, mainly calcium ions and magnesium ions are formed, dissolve these salt
And tunnel waterproof and water drainage system function and concrete are not influenced as far as possible, not seriously affecting to environment and ecology composition is this problem
Focus.In addition, to be considered, easy for construction, dredging speed and Cost Status etc..
Therefore, during using foregoing invention scheme, a large amount of experiment has been carried out, has been experimental program below, from this
As can be seen that finally selecting the reasonability of scheme of the present invention in a little experimental programs.
One, experimental program:
A. complexometry: in view of not influencing tunnel waterproof and water drainage system function and concrete, serious shadow is not constituted to environment and ecology
It rings, complexometry is the method being readily apparent that.Most common calcium ions and magnesium ions complexing agent is mainly EDTA(disodium ethylene diamine tetraacetate)
Calcium ion complexing agent, NH4Cl saturated solution, iminodisuccinic acid sodium (IDS) etc. are directed to the complexing agent of calcium ion.
A. disodium ethylene diamine tetraacetate is used alone as complexing agent
According to EDTA: water=4g:100g, wiring solution-forming.One gram of blind pipe blocking solid sample is put into EDTA solution, is had a small amount of
Gas is released, and is hastened very slow, after placing a period of time, solid still has residue, and EDTA is adjusted to alkalinity with ammonium hydroxide, is put into sample
Afterwards, undissolved solid, no gas are released.
B. weak acid+complexing agent
Then, NH is configured4Cl saturated solution (ammonium chloride shows faintly acid), takes supernatant liquor as calcium ion complexing agent.Work as addition
After solid sample, undissolved solid is also released without gas, illustrates that ammonium chloride is acid not enough.
The method of this weak acid+complexing agent does not succeed.
C. using citric acid as complexing agent
Citric acid is both complexing agent, while having both acidity.Configure citric acid: it is added in solid sample by water=5g:100g solution
In, there is gas to emerge, reacts slower.Mainly it is acid in action.
Brief summary: processing sample solid only is removed with complexing agent, is had little effect, solid dissolution is less, infeasible.
B. washing method
Using foaming agent, thickener etc. configures aqueous solution, reduces the adhesive force of sediment, using washing method by solid rush to
It falls off.
Firstly, configuration sodium dodecyl sulfate solution (2%-5%), after solid is added, solid is insoluble, configures acid thickening
Agent improves liquid viscosity and its lubricity, and after sample is added, solid is still insoluble, but liquid becomes more lubricious.Individually make
With complexing agent and its surfactant, thickener etc. all can not directly dissolve sample solid.
C. acid system
Whether there is or not machine acid and organic acids for common acid reagent.Inorganic acid can only use hydrochloric acid, and phosphoric acid cannot use, because of calcium phosphate, phosphoric acid
Magnesium is insoluble in water, is unable to reach the purpose of removal solid.Sulfuric acid can not be used, because calcium sulfate is also sl. sol..
Organic acid is relatively more, such as acetic acid, formic acid, citric acid, lactic acid, oxalic acid, tartaric acid etc..But organic acid belong to it is weak
Acid, some are acid not enough, and solute effect is bad, some are too expensive.
2H++MCO3→M2++CO2+H2OM=Ca,Mg
Solution principle:
A. dissolving with hydrochloric acid method
Hydrochloric acid is one of traditional strong acid, and in addition two kinds are sulfuric acid and nitric acid.Sulfuric acid is slightly soluble in because generating calcium sulfate in the reaction
Water, effect are undesirable.Nitric acid is easy to produce toxic gas (NO, N in course of dissolution2O etc.), while also there is oxidisability, one
As careful choosing.Three strong acid all have obvious and quick corrosiveness to reinforcing bar, cement.
Table 1: dissolving with hydrochloric acid effect
Conclusion: A. does not need any external subsidiary conditions in the case where not heating (room temperature), uses hydrochloric acid merely, can
The dissolution of solid matter is realized well.B. hydrochloric acid has very strong corrosiveness to reinforcing bar, cement (even acid-resistant cement).
C. hydrochloric acid residual can produce bigger effect natural environment water quality, chloride ion will cause the salinization of soil into environment.It is recommended that using
Dilute hydrochloric acid, or hydrochloric acid is not used preferably.
B. acetate dissolution method
In organic acid, acetic acid is that (acid condiment vinegar, is exactly the water-soluble of acetic acid to the most common acid in we daily life
Liquid), price is relatively low.
Table 2: acetate dissolution effect
Conclusion: acetic acid is active lower on the whole, and solid matter dissolution is slower, is used alone not ideal enough.
C. formic acid dissolution method
Formic acid is the acid and simplest organic acid containing a carbon atom in organic acid.Acidity is eager to excel much than acetic acid, but
It is to still fall within weak acid.
Table 3: formic acid solute effect
Table 4: influence of the formic acid to reinforcing bar and cement
Conclusion: formic acid has reproducibility, can be with light degradation, biodegrade and oxidative degradation, and effect on environment is relatively small；Room temperature
Under be corrosive to cement (when constructing tunnel, for drainage pipeline cement position, it is proposed that use acid-resistant cement), to reinforcement corrosion
Property is small, it is recommended to use.
D. citric acid solute effect
20% citric acid solution is slower to the solution rate of solid at room temperature, but has for more firm calcium sulfate precipitation
The effect for reducing adhesive force makes solid be easy loose fall off in this way in giant flushing process.When heated, it dissolves
Fast speed.
E. mixed-acid dissolution effect
Table 5: mixed-acid dissolution effect
Conclusion: being added after hydrochloric acid, and hydrochloric acid is reacted with solid matter first, and when hydrochloric acid consumption, weak acid formic acid and acetic acid all may be used
To supplement hydrogen ion, solid is allow to continue to dissolve, so it is feasible that diluted hydrochloric acid dissolution solid, which is added,.Formic acid and lemon acid-mixed
It closes, reacts slightly slow at room temperature, but meltage is larger, only the time is slightly longer；When heated, reaction speed has very fast promotion,
Effect is more satisfactory.
F. influence of the acid to reinforced concrete
Table 6: influence of the acid to reinforcing bar
Table 7: influence of the acid to cement
Conclusion: hydrochloric acid has obvious corrosiveness to reinforcing bar, cement at room temperature；Formic acid, acetic acid, citric acid are at room temperature to reinforcing bar
Corrode slower；Formic acid has corrosion to cement at room temperature, and acetic acid and citric acid are smaller on cement influence at room temperature, but diluter first
Acid corrodes cement slower.
D. synthesis
First with the effect of acid, makes the solid sample dissolution for being insoluble in water, the metal ion for being dissolved in water is released, secondly, sharp
With complexing agent, complexing fixation is carried out with the metal ion having been dissolved in water, forms soluble complex compound, then, using adding
Surfactant, thickener for entering etc. improve the lubricity of liquid and inner surface of container, reduce sediment to the adhesive force of pipeline,
Finally, the attachment of the complex compound dissolved and its loosening is gone out with water using hydraulic pressure.
A.EDTA: citric acid: dodecyl sodium sulfate: water=4:4:1:100；
Under room temperature: 1g sample is added, sample dissolution continues bubbling, the duration is longer, but speed is more slow, there is a small amount of bubble
Foam generates.
Under hot solvent: 1g solid is added, a large amount of foams generate, bulk sample fragmentation, become smaller solid, but solid dissolves
Speed or relatively slow.
B. formic acid: citric acid: sodium cellulosate: water=3:1:0.4:15
Under room temperature, 1g solid is added, solid dissolution has a gas releasing, early period fast speed, the later period slows down, and hot water is then added
Afterwards, reaction becomes violent again.
When configuring solution using hot water, solid sample dissolves rapidly, reacts the later period, and temperature reduces, and speed slightly slows down.
C. acetic acid: citric acid: water=5:4:100
Room temperature reaction is slower, and possible or acid must be inadequate.
60 DEG C of dissolution 1g solids are heated to, reaction acutely, there is bubble releasing.
D. formic acid+citric acid+V98 thickened lubricant+water=20ml+5g+1ml+50ml
Reaction is very fast at room temperature, and effect is preferable.
E. formic acid+citric acid+V98 thickened lubricant+water=10ml+5g+1ml+50ml
React very fast in hot water, effect is preferable.
It summarizes: passing through system experimentation, it has been found that dissolving with hydrochloric acid effect is good, all has dissolution to blind pipe solid, reinforcing bar, cement
Corrosiveness, also having on environment not bery influences.Whether room temperature construction or heated condition all can be used, and effect is fine.
Using above-mentioned tunnel blind pipe Crystallization Plugging scavenger, proportioned scavenger is injected into tunnel blind pipe, is made clear
Except agent is sufficiently reacted with the crystallization in tunnel blind pipe, reaches dissolution blocking crystallization purpose, promote the draining of blind pipe smooth.To have
The blockage problem for solving tunnel blind pipe of effect greatly reduces tunnel because of danger of collapsing caused by infiltration, ensure that tunnel
Structure safety.Scavenger after cleaning can be recycled by recyclable device, can be avoided pollution with effective protection environment.
