Abstract
An anti-seepage leaking stoppage repairing material for concrete buildings is composed of 15-40 parts by weight of polyacrylamide, cement, sand, calcium chloride, a water reducing agent, triethanolamine, salt, gypsum and sodium nitrite, 50-100 parts by weight of gypsum, 0-75 parts by weight of sodium nitrite, 0-1.5 parts by weight of sodium nitrite, 0-0.05 parts by weight of sodium nitrite, 0-0.5 parts by weight of calcium chloride, 0-1.5 parts by weight of sodium nitrite and 0-0.05 parts by weight of sodium nitrite. It can be widely used for reservoir plugging, mine mud and sand flow plugging and concrete building seepage-proofing plugging. The anti-seepage plugging material for more than 30 reservoirs proves that the material has the characteristics of low cost, convenient construction and the like in more than five years, and the reinforced material has the performances of compression resistance, bending resistance, firm bonding, ageing resistance and the like, and is popular with users.
Description
The present invention relates to anti-osmosis, leakage-stopping material for repair of concrete buildings, particularly the anti-osmosis, leakage-stopping material for repair of concrete buildings formed such as polyacrylamide.
The culvert pipe in reservoir, power station or water pipe, great majority adopt cement to coagulate soil, because the tensile strength of cement concrete is low, reasons such as resistance to cleavage difference are easy to generate the crack, thereby cause the structure ginseng to leak or wall erosion.For the safety that guarantees hydro project itself and bring into play its due benefit, must carry out reinforcing to its disease and handle.Macromolecular compound is used widely as the concrete structure impervious blocking material.For example GB2188-937-A discloses a kind of patching materials of being made up of soaker and waterproof polyurethane etc.Particularly the material that is used for submerged structure of polyacrylamide composition has good ultimate compression strength-JP60155559.This patent organic high molecular compound component complexity, and need with the ion exchanged water configuration, nothing is congealed into, and this is higher, complicated operation.For hydrometallurgy of uranium tail storehouse flood tunnel concrete wall cracking, water yield reach 23 meters 3/ hour, the crackle that this class flow velocity is bigger, general water-proof plugging material is difficult to prove effective.Therefore seek a kind of new leak stopping injecting paste material, it can be leaked and slip casting by the top water blocking, operation again must be easy, and price is cheap, is the problem that presses for solution in the hydro project.
The objective of the invention is to solve above-mentioned problem, develop a kind of energy top water blocking and leak and slip casting anti-osmosis, leakage-stopping material for repair of concrete buildings easy and simple to handle, cheap.
Through repetition test prescription and leak stopping practice, filter out patching materials of the present invention and mix by following component:
P---polyacrylamide;
C---cement;
A---sand;
B——CaCl
2；
D---water reducer (commercially available CA or NF type);
E---trolamine;
F---salt;
G---gypsum;
H---Sodium Nitrite
The weight quota ratio of each component is:
P∶C∶A∶B∶D∶E∶F∶G∶H＝15～40∶50～100∶0～75∶0～1.5∶0～1.5∶0～0.05∶0～0.5∶0～3∶0～1。
Use batching of the present invention, successfully blocked on certain hydrometallurgy of uranium tailings storehouse flood tunnel concrete wall in 1984, water leakage reaches 23 meters
3/ hour crackle.Through time more than 5 years and more than 3000 meter of 30 reservoir culvert nearly
3Reinforcement applications prove; Material of the present invention be used for the reservoir culvert reinforcement have easy and simple to handle, characteristics such as short construction period can top water or submersible, and is nontoxic substantially, and construction is not subjected to environment and season limit, and material is cheap.
To the performance of material of the present invention, entrust Nanjing Hohai University to test, its result is:
1, unit weight (saturated unit dry weight) is 2200 kilograms/meter
3
2, pressure-proof elasticity modulus:
Sample dimensions: 10 * 10 * 30 centimetres.
Pressure-proof elasticity modulus E=1.70 * 10
4MPa, more concrete pressure-proof elasticity modulus E1=1.81 * 10
4MPa is low, illustrates that material deformation performance of the present invention is good, and is proper as patching material.
3, resistance to compression, anti-folding and tensile strength:
Table 1 is enumerated mortar of the present invention and conventional cement mortar 250
#Average intensity value at different times.(table 1 is seen the literary composition back)
As seen from Table 1, though made the mortar strength of the present invention of phase little at 28 days than conventional cement mortar, but its intensity level increases comparatively fast with the increase that makes the phase, when making the phase in 120 days, the intensity of mortar of the present invention is big than sand-cement slurry just, and folding strength obviously increases, and this is comparatively favourable to supporting material.
4, adhesive property:
Table 2 is listed in the split tensile strength contrast of mortar of the present invention and normal concrete and mortar.(table 2 is seen the literary composition back)
By table 2 as seen, the tensile splitting strength of mortar of the present invention is slightly high than ordinary concrete.And mortar of the present invention and concrete cohesive strength sum all greater than 1, illustrate that it and concrete cohesive strength have surpassed normal concrete (250 along the value of all directions
#) tensile splitting strength own, material of the present invention being described as supporting material, its cohesiveness to former water conservancy project matrix provides reliable assurance.
5, ageing resistance:
Mortar of the present invention, sand-cement slurry pressure-proof and snap-resistent aging intensity is listed in table 3.(table 3 is seen the literary composition back)
By table 3 as seen, mortar of the present invention through 90 days temper(ing) after (temper(ing) was equivalent to Nanjing area weather aging 1 year in one month) its strength aging factor greater than the strength aging factor of high-grade cement mortar, this illustrates that material ageing resistance of the present invention is superior.(table 4 is seen the literary composition back)
6, anti-permeability performance:
The watertightness parameter of mortar of the present invention is 14.03MPah.250
#The watertightness coefficient of conventional cement mortar is 6.54MPah.The watertightness coefficient of the clean slurry of material of the present invention is 19.6MPah.Illustrate that material of the present invention has good barrier performance.
Embodiment:
Now further specify the present invention in conjunction with the embodiments, but be not limited to these examples.
Now 16 kinds of prescriptions are listed in table 4, the component in the table is a weight part.
Be applied to the leak stopping of uranium ore tailings storehouse flood tunnel through the material of 16 kinds of prescriptions, intercepting of the silt particle stream of certain metallic ore courtyard waste mantle, 1.9 meters of certain power station water conveyance culvert or pipe diameters, the culvert pipe wall big area honeycomb that length overall is 787 meters, the antiseepage reinforcement of leakage point etc. is handled, the expansion joint of certain reservoir and the reinforcement of inside pipe wall, certain power house emptying culvert pipe is because of earthquake shocking cracking, form long 1.5 meters together, wide 10 centimetres crack is because of per hour about 100 meters
3Swelling go into factory building and stop work.With material processing of the present invention three days, 30 meters of impervious leakage-stoppings
2, the 5th day normal power generation.Nearly in the reinforcing construction of 30 reservoirs,, fully demonstrated material of the present invention and had nontoxic in recent years for reservoir has solved a difficult problem one by one, do not fire, cost is low, and constructing operation is easy, short construction period, the characteristics of energy top water operation, the material after the crackle reinforcement has resistance to compression, performances such as anti-folding combines firmly with concrete substrate, and is anti-aging, stood the test of time, the Subscriber Unit reaction is fine, in 16 kinds of component prescriptions, with effect the best of embodiment 13.
