Summary of the invention
Its object of the present invention is just to provide a kind of Waterproofing Technology of Underground Works technique, solves conventional waterproof construction destroyed, and the problem that next procedure has been difficult to remedy after having started construction.Have that construction is simple, conveniently remedy after breakage, be conducive to controlling and the feature of good water-proof effect.
Realize above-mentioned purpose and the technical scheme taked, comprise step,
(1) woven dacron and second third water-proof liquid rubber coating is processed
Need lay woven dacron length according to construction Size calculation, and cutting is intact in advance, stirs second third water-proof liquid rubber coating;
(2) brushing primer
Brushing primer, dry 4-6 hour after coating;
(3) brushing water-repellent paint
By woven dacron be fixed on basal plane intact based on, first vertical brushing second third water-proof liquid rubber coating first pass on woven dacron, evenly be coated with vulcanite scraper or hairbrush and scrape, second coating can be carried out after cured, adopt and evenly brush at coating surface with the orthogonal direction of first coating, after solidification, then the 3rd road film is scraped in painting, and coating thickness adds woven dacron thickness and reaches designing requirement;
(4) rarely face slag is spread
If wallboard facade will be plastered, last one coating construction complete but also uncured time, should surface be rare sprinkles sand grains clean on a small quantity, to increase the adhesion stress of film and cement mortar at it;
(5) examination of film waterproof material
Conscientiously must check the construction quality of film waterproof material before doing topping, require that full coat is continuous, thin and thick uniformity, tight-closed, not allowed shows money or valuables one carries unintentionally sees the bottom, play that drum comes off, the existence of the defect such as tiltings of ftracture, if desired can retaining inspection, and extremely non-leakage is qualified;
(6) topping construction
When after film acceptance(check), get final product making cement mortar cover or use paving brick.
beneficial effect
Compared with prior art the present invention has the following advantages.
1) waterproofing course material of main part second third water-proof liquid rubber coating has the characteristic of good weather resisteant, resistance to ozone and resistant to chemical media corrosion, and physical and chemical performance is excellent, uses birthday noodle to reach 50 years; There is complete waterproof detail treatment structure, adopt Special seal cream to close detail treatment position, with the multiple-sealed defence line of the supporting formation of main material bonding adhesive, improve the whole structure of waterproofing course;
2) technique is simple, and material requested and machining tool are and on-the-spotly often use, and processing is simple, speed of application is fast, be conducive to controlling.
Detailed description of the invention
Comprise step,
(1) woven dacron and second third water-proof liquid rubber coating is processed
Need lay woven dacron length according to construction Size calculation, and cutting is intact in advance, stirs second third water-proof liquid rubber coating;
(2) brushing primer
Brushing primer, dry 4-6 hour after coating;
(3) brushing water-repellent paint
By woven dacron be fixed on basal plane intact based on, first vertical brushing second third water-proof liquid rubber coating first pass on woven dacron, evenly be coated with vulcanite scraper or hairbrush and scrape, second coating can be carried out after cured, adopt and evenly brush at coating surface with the orthogonal direction of first coating, after solidification, then the 3rd road film is scraped in painting, and coating thickness adds woven dacron thickness and reaches designing requirement;
(4) rarely face slag is spread
If wallboard facade will be plastered, last one coating construction complete but also uncured time, should surface be rare sprinkles sand grains clean on a small quantity, to increase the adhesion stress of film and cement mortar at it;
(5) examination of film waterproof material
Conscientiously must check the construction quality of film waterproof material before doing topping, require that full coat is continuous, thin and thick uniformity, tight-closed, not allowed shows money or valuables one carries unintentionally sees the bottom, play that drum comes off, the existence of the defect such as tiltings of ftracture, if desired can retaining inspection, and extremely non-leakage is qualified;
(6) topping construction
When after film acceptance(check), get final product making cement mortar cover or use paving brick.
During described brushing primer, second third water-proof liquid rubber coating can be added water and stir, so that brushing, to be 0.2 ~ 0.3 Gong Jin/㎡ be coating weight.
Described brushing water-repellent paint first pass every square metre of consumption is 0.8kg/m2, and second coating painting amount is identical with first, the 3rd road film, and painting amount is 0.4-0.5kg/m2.
