Professional to provide you with: a residential district, by a senior and a multi-storey (including basement) of residential, with a total area of ??42,000 square meters, a 23 story high-rise commercial and residential building, frame structure, basement, 22 on the ground floor, the basement of 600 mm reinforced concrete foundation. Because the building just south of the Millennium endless Jinghe, high water table, the water pressure is greater, for the construction side of the basement seepage scientific organization of work to do construction, engineering seepage successfully resolved technical problems. Second, the type of basement leakage prevention technology 1. formwork and reinforcement plate causing leakage of water seepage: wall panels for support provided template, steel formwork laying on the floor, on the floor after construction steel cutting surface, due to the reinforcement without the protective layer, the formation of chemical corrosion, causing serious water seepage. 2. Cellular, pockmarked face, ditch hole untreated or treatment is not complete cause leakage: Because vibrated concrete is not dense, there cellular, Pock, trench cave, and when dealing with not tick loose concrete admixtures unused mixed the same proportion of fine aggregate concrete repair mortar and mortar and not dense, resulting in the leakage of loose concrete. 3. Design of concrete waterproofing itself since leakage: the actual project, due to the structure and complexity of the construction, such as steel-intensive, foundation settling differences, gravel, clay volume, labor mobility is not strong sense of responsibility and other reasons, waterproof concrete itself may produce leakage leakages. Therefore, the high-water areas designed basement waterproofing best use of multi-channel water line. 4. the wall and floor junction leakage: the junction of the wall and the floor and the surrounding part of a damp, dripping phenomenon, both junction leakage points. Analysis of the leakage reason is due to the next floor vibrated concrete step has been completed prior to the floor and the wall vibration of 20 to 30 cm high concrete side led by vibration, so that is not dense concrete vibrators. In addition, the wall of concrete does not sink in the template support, while concrete floor vibration sinking crack in the wall at the same time stress that the site is too concentrated, conservation is not timely also cause chapped cause leakage. Therefore, when the lower floor vibrated concrete, do not plug into the upper concrete vibrators and holding a two-step concrete junction, leaving a certain distance, and should be greater than the amplitude of vibrators, vibrators have been avoided finished concrete floor and the wall again by vibration; high foot of concrete pouring, should the initial setting of concrete after pouring the floor, taking care not to insert the vibrator has the initial setting of the concrete floor inside. 5. reinforced protective layer thickness is not enough cause leakage: External groundwater through the outer surface of a thin steel plate into the surrounding floor to protect steel, reinforced concrete crevice corrosion so, reinforced along the direction of the interior basement seepage. It is recommended that the design in the basement, the outside of the plate, outside of the exterior walls reinforced protective layer should be set according to strict specification and appropriate protective layer thickened, turn-like construction, processing, steel banding should take the negative difference, avoid reinforced Inflation caused due to almost no protective layer. 6. wall formwork bolts approach to improper leaks: Exterior wall sealing plate welded bolts are not tight, or through the wall of the outer walls remain head bolts longer cutting, external wipe mortar failed to strictly reinforced bonnet in particular steel head exposed outside the plaster layer, worn waterproof waterproof layer formed under the groundwater chemical corrosion effect and continue to corrosion caused by leaking to the interior direction. 7. Sealing settlement joint misalignment causing leaks: settlement joint leakage is relatively common, due to cracks in the rubber sealing tape easily fixed firmly, often moves when pouring concrete, and some serious moves, especially the top and bottom water stop often fall on lower steel. Easy to implement concrete below the level of the water stop, often forming trench cave, cellular, hemp noodles. Therefore, the construction should be welded steel bone, fixed the water stop at the exact position to be below the level of the water stop after pouring concrete compacting, and then fixed water stop. 8. have to find things in concrete resulting in leakage: easy to cause leakage, it must be close to the inner wall 10 cm wide when there is concrete wedge, wood, wooden, polystyrene board, brick, woven bags and other debris Remove debris, but also by high-pressure torch burning, clean and then plugging. 9. steel exterior wall leakage intensive areas: external walls and inside corner junction column clusters reinforced roof leaking, because these parts of the small space, pouring hard, dense concrete difficult, resulting in leakage. So the application of iron steel wedge or wedge will temporarily separated, and then pouring concrete, preferably pisolite concrete pouring, and sent people management. 10. exterior waterproofing layer formation leakage unreasonable practice: Exterior paint waterproof layer do before, must be concrete and mortar screeds, and catch-pressure light. Because there are more concrete surface water hole after form removal, if done directly waterproof coating layer, coating the surface of the water will also form many eyes, the root causes of basement leaks. In addition, if wiping leveling layer, but not in a hurry-pressure light will cause the coating thickness over the uneven surface of the hole made after coating waterproof layer. When gravel backfill, because deep foundation must string tube, not directly to the tank pit overturned car, smashed the protective layer to prevent sand and waterproof layer. Third, successful plugging plugging techniques 1. Analysis: plugging of numerous materials and technical performance of waterproof materials do not understand, do not pay attention to waterproof technology research. Construction, not looking for leakage points, leaking lines; see the seam leaks that straddle drill grouting; see that a wall of water seepage wall drill grout or brushing the wall surface coatings; see settlement joint water leak tick chisel filling rigid waterproof material or perfusion hot asphalt sealing and so on. This blind hole, filling the blind, the end result is blindly plugging drilling does not enter into the pulp slurry or difficult, settlement block rigid waterproof material, after cracks continue leaking, not really the point of leaking, leaking lines, leaking joints blocking Yan causing plugging unsuccessful. Simply using a variety of paint in the mortar or concrete surface is coated with a film layer plugging, ignoring the hidden leakage point, leaking joints treated only point blocking, line plugging and plugging topcoat combine to succeed. So for key positions and settlement plugging leaks should adopt multi-channel water line. 2. The success of the principles and methods of plugging: You must find by tick chisel clear leakage points, leaking line, targeted for plugging. For leakage points, line plugging leaks take rigid binding principles combine to enhance the expansion just outside the soft, that must be carried out internally within the joints, combined with the use of rigid, expanded four plugging enhance the binding effect is very good defense, that is, from followed by soft inside out, just, Sophie, just four lines of defense; embedded parts around plugging leaks, tick chisel a certain depth, the use of inorganic permeable rigid waterproof material and accelerator plugging; internal leakage of line pipe water plugging, plugging must plug in real time; basement plugging only works from the inside, a reasonable plan, proper operation, in order to obtain good results. ************************************************** ***************** "The company" unity and hard work, forge ahead, rigorous and realistic, hard work, "the business style, continuous innovation, relying on a strong scientific management and quality services, uphold the "integrity and realistic, social services, credit first, customer first" corporate purposes.
