A kind of concentration basin, pond seepage restorative procedure
Technical field
The present invention relates to a kind of job practices, especially a kind of concentration basin, pond seepage restorative procedure.
Background technology
The application in mine construction of concentration basin, pond is very many, and the waterproof of the concrete in mass of concentration basin is the difficult problem in the construction always.The concentration basin body is big, and concrete-pool-wall is thinner, and impervious, waterproof has saying of ten ponds, nine leakages, mainly be reflected at concentration basin concrete impervious, leak preventing effect is not good, after construction is accomplished, most of exist control Lou, the leak stopping phenomenon.Cause the reason of concentration basin, pond seepage to mainly contain following several kinds: 1. to adopt commercial concrete during the concreting; Because of far away apart from agitator; In time do not handle with bottom concrete junction after concrete is marched into the arena, combine leakiness after the levels concreting.2. use steel form to install, the slit between template and template lacks sponge strip, causes the concrete spillage, thereby has reduced concrete impervious ability.3. concrete mixing plant use cement amount and flyash amount are incorrect, and the concrete heat of hydration is high, does not have the admixture retardation water reducing agent in the concrete; Temperature is high during construction, after the form removal pool wall maintenance untimely, cause concrete internal temperature high; Internal-external temperature difference is big, and concrete has produced miniature crack.Concentration basin wall seepage is the seepage at the constuction joint place mainly, 1. mainly shows base plate and wall junction; 2. the constuction joint position is not cleaned out, and loosening particle and cement (top layer) film are not rejected; 3. connect raft place template piece leakiness and cause spillage; 4. during placing of concrete, spread slurry and handle at the constuction joint place; 5. it is improper to feed intake, and concrete coarse aggregate is concentrated.
According to above-mentioned analysis, solution concentration basin, pond seepage are the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of concentration basin, pond seepage restorative procedure.
The technical scheme that the present invention solves its technical problem is:
A kind of concentration basin, pond seepage restorative procedure may further comprise the steps,
-dig groove in leakages, recess-based aspect water is rinsed well,
-fixing the Grouting Pipe of segmentation in the good groove of cutter,
-divide with accelerating admixture and 2 times groove to be filled and led up, and firmly compacting,
-in Grouting Pipe, inject polyurethane with grouting pump,
After finishing, the injection of-polyurethane uses the xylenes cleaning equipment immediately, in order to avoid the grouting pump damage,
-treat that accelerating admixture solidifies the back and slices off Grouting Pipe,
-on accelerating admixture, paste foam plastics strip,
-fill the polysulfide rubber sealant from the groove joint both sides to the centre then,
-smear waterproofing mortar,
-be coated with the XYPEX concentrate.
The technical scheme that the present invention solves its technical problem can also be:
The wide 20mm of groove of the present invention, dark 40mm.
Of the present invention section is 2.5m, and promptly average every 2.5m groove is installed a Grouting Pipe.
Accelerating admixture of the present invention is that golden soup does not leak, XYPEX repairs sealing agent, water soluble polyurethane leak-stopping agent and XYPEX concentrate.
The polyurethane of penetrating of the present invention is yellowish, amber transparency liquid for the outward appearance tone; Density is 1.1~1.2 g/cm^3; Viscosity is 1.3~1.5MP.S in the time of solvent-free 25 ℃; Viscosity is 0.3~1.0MP.S when containing 25 ℃ of solvents; Inducing consolidation time is 2~3min; Impervious Wei ≧ 0.8 MP of induration; Expansion rate is 2~3 times.
The key technical indexes that golden soup of the present invention does not leak, XYPEX repairs sealing agent, water soluble polyurethane leak-stopping agent and XYPEX concentrate is: 1. setting time 1~90min is adjustable; 2. compressive strength 30~40Mpa; 3. adhesion strength>1.5 Mpa; 4. impermeability:>0.7 Mpa; 5. high-low temperature resistant is 100 ℃~-40 ℃.The present invention has the following advantages:
Advanced: this water-stopping method advance is that technology is simple, does not destroy structure, and easy to operate, effect is obvious, in forming the structure of leaking, can bring into play the effect that As the medicine took effect, the symptoms lessened, is worth learning and promoting.
Practicality: this waterproof method practicality be method easy economical and practical, can fundamentally solve seepy question, pollution-free and environmental protection and energy saving.
The scope of application: this water-stopping method is adaptable across various buildings.Because of this water-stopping method need not naked light, permanent fire retardant in work progress.On inflammable, explosive enterprise high temperature building, use better effects if.
After concentration basin adopted the slip casting method waterproofing work, original linear flow infiltration and wet stain phenomenon no longer showed on pool wall of pool, the base plate.Explain that the reason and the water seepage treatment method that seep water on pool wall, the base plate are correct, and also be successful the waterproofing work in pond.

The specific embodiment
A kind of concentration basin, pond seepage restorative procedure may further comprise the steps,
-dig groove in leakages, recess-based aspect water is rinsed well,
-fixing the Grouting Pipe of segmentation in the good groove of cutter,
-divide with accelerating admixture and 2 times groove to be filled and led up, and firmly compacting,
-in Grouting Pipe, inject polyurethane with grouting pump,
-treat that accelerating admixture solidifies the back and slices off Grouting Pipe,
-on accelerating admixture, paste foam plastics strip,
-fill the polysulfide rubber sealant from the groove joint both sides to the centre then,
-smear waterproofing mortar,
-be coated with the XYPEX concentrate.
The wide 20mm of described groove, dark 40mm.
Described section is 2.5m, and promptly average every 2.5m groove is installed a Grouting Pipe.
Described accelerating admixture is that golden soup does not leak, XYPEX repairs sealing agent, water soluble polyurethane leak-stopping agent and XYPEX concentrate.
The described polyurethane of penetrating is yellowish, amber transparency liquid for the outward appearance tone; Density is 1.1~1.2 cm^3; Viscosity is 1.3~1.5MP.S in the time of solvent-free 25 ℃; Viscosity is 0.3~1.0MP.S when containing 25 ℃ of solvents; Inducing consolidation time is 2~3min; Impervious Wei ≧ 0.8 MP of induration; Expansion rate is 2~3 times.
The key technical indexes that described golden soup does not leak, XYPEX repairs sealing agent, water soluble polyurethane leak-stopping agent and XYPEX concentrate is: 1. setting time 1~90min is adjustable; 2. compressive strength 30~40Mpa; 3. adhesion strength>1.5 Mpa; 4. impermeability:>0.7 Mpa; 5. high-low temperature resistant is 100 ℃~-40 ℃.
