Phone: (0) 13961999789 (0) 15862087268 plugging leakage causes and solutions: Tunnel leakage treatment works most of the key structures of reinforced concrete thin-walled structures, even with the surface of the water layer and other measures, along with the use of time tunnel waterproof layer surface leakage failure also occurs. Treatment for a crack crack various causes, we must make the necessary treatment, depending on the type and size of the cracks, there are several treatment methods. 1.1 surface crack repair method for small (<0.2mm), surface repair method is a simple, common repair methods. It is mainly applied to stabilize and treatment had no effect on the structure of the carrying capacity of the surface cracks. Traditional treatment measures are cracks in the surface of smear grout, epoxy mastic or painted anti-corrosion materials in the concrete surface. Now a new waterproof, anti-corrosion coatings - spherical polymer modified cementitious capillary crystalline product, has been widely used, it can still crack bridging 0.3mm below the surface of the adhesive with the construction of high-strength, weather resistance, anti-UV exposure, as long as the structure is not damaged, it is permanent. 1.2 caulking sealing method for crack than 0.3mm, especially mobile crack closure is necessary to combine grouting treatment when necessary. Caulking cracks sealing method is the most common method, it is usually along the cracks gouges in the tank filled, rigid plastic or sealing material to achieve the purpose of the closure of cracks, Figure 1 is that we move cracks governance A method employed. Process: crack slotted parts, clean up loose parts, blocking legislation sealing (quick-drying cement), (if out of water, then buried Tsui Note polymer materials Grouting), wiping flexible excellent sealing (a polymer modified cement based waterproofing material) after together, put strengthen flexible network optimization just wipe the surface layers. 1.3 Replacement Concrete grout for crack-intensive area, usually due to construction quality or the quality of materials (such as the occurrence of alkali aggregate reaction) resulting in partial loose, irregular surface cracks intensive, even when the leak occurred in the tunnel wall joints, they have In addition to the existing concrete cutting, combined with grouting repair. Filling aimed at repairing an impact on the structural integrity requirements or seepage cracks in concrete, it is the crack using a pressure device material into the cement in concrete, cement and concrete material hardened to form a whole, and thus play a seal blocking reinforcement purposes. 2.1 Construction Principle 2.1.1 Summary grouting a. Grouting is a new chemical grouting plugging technology, which uses double grouts. Proportionally weighed five kinds of materials made from A fluid mixing water in proportion weighed B desulfurization add water and stir into the liquid, when the two liquids mix after polymerization reaction, the initial setting of 30 seconds, 2-3 minutes, the reaction is complete, the final cemented colloids. Grouting injection structure layer using a water-soluble form, low slurry viscosity, permeability, can be injected into the cracks of 0.1mm or less; slurry in the wet, the water speed large, multi-criteria aggregation under water; gel also has good permeability, the case expansion of water, corrosion resistance and other characteristics, colloidal compressive 0.01-0.06MPa, tensile strength 0.02-0.04MPa. b. grouting method is mainly used in a large amount of water leakage, water dispersion, is not conducive to sealing cracks and individual water points, faces. According to determine the location of the crack closure status. Internal grouting to seal the water channel and cracks, or water flow is relatively concentrated, easy to block. Leakage greater than 150mL / min centralized water points, using water shutoff grouting method. The first point in the water jacket grouting mouth, so as not to penetrate the depth of the structural layer, preferably not less than 10cm, so can avoid serous hyperdiffusion phenomenon, but also to clear the water around the point when the deep-rooted minor fissure grouting, play vent Pressure. Then gravel ballast float inside seam clean, with plugging Wang caulk joints filled in, and then trimming mortar mouth. 21.2 grouting concrete construction steps a surface treatment: the concrete surface cracks about 10cm processing net, find the location of cracks and water. b gouges: artificial carved depth of 8cm (construction joints) or 6cm (liner cracks) in the slot, usually hewn large (6cm) Minor (4cm) inverted trapezoidal groove, ensuring topical waterproof layer 2-3cm thick. c embedded grouting pipe: For between water pipes and buried sleeve seam leaks, the first of leakage points chiseling depth of less than 70mm, the water washed away after installation hemp rope, and then sealing materials for closure 1-2 grouting pipe embedded diversion. . d grouting: sealing materials such as waterproof mortar reaches a certain intensity, from the tube into the slurry grouting; grouting pipe next to the appropriate according to circumstances out of slurry grouting effect judgment strive slurry filled the gap and distribution; grouting pressure control in 0.3-0.4MPa, generally determined by field tests; after completion of grouting, grouting iron Sizha prison nozzle to prevent the outflow of slurry; Once the slurry induration, cut grouting pipe. . e swabbing leveling: waterproof mortar reaches a certain intensity, wet the repair area, brush 1: 2 ordinary mortar, thickness 0.5-0.8cm. . f conservation: water conservation in three days. 2.1.3 tunnel plugging grouting first principle point drain water injection grouting lesser, greater after injection; in the ring in order to crack up by grouting; horizontal or diagonal cracks from the small end to the large end of the water injection pulp; surface leakage from the periphery to the center in order grouting. 2.1.4 Grouting end standard considerations of surface leakage if water has effectively block principle. Technical measures to ease the closure grouting: The hole in the fabric of the existing grouting should consider plugging leakage of water, should be carried out in the grouting grouting grooming, which is to inject slurry, when there is leakage of water gradually changing the slurry overflow slurry concentration, adjust the slurry gel time, so to divert water leakage at the block by grouting from the inside out. If during grouting part leaks can not achieve the purpose of the overflow slurry, perform leakage points are located grouting hole, so as to achieve outside-filling and sealing slurries.

Construction performance throughout the country .. one, tunnel Deformation (including expansion joints, settlement, construction joints, cross joints) leakage reasons: (1) the reasons for the special design of specific parts of the environment with special features, in such Deformation and other detailed structure, the lack of effective, combined with the specific circumstances of the waterproof design, resulting in leakage of these sites. (2) the reasons for the selection of materials suited to poor material deformation requirements or caulking material properties (3) failure to require the construction of water stop construction reasons, caulking sealant failure to require the construction. Second, the tunnel plugging Treatment: Set Deformation purpose is to absorb or buffer structure stress due to temperature differences, settlement, vibration and other factors that, in order to avoid cracking or damage to the concrete structure. Deformation have built houses in the basement due to reasons such as construction materials and water leakage situation. Due to constraints (unable excavation), can only be processed in-house engineering dorsal surface, usually grouting, caulking, paste and other methods. 1, the tunnel plugging grouting and caulking method: Deformation bound by the original filler, surface cleaning to water stop, after the rinse, the use of speed Ningzhi water pumping pipe materials, pipe, water operations, concave Do not fill the tank in order to leave room for caulking, laying a packer at a certain distance, quick-setting material reaches a certain intensity, can be elastic sealing slurry perfusion pressure by packers, has been filled to not Deformation then the water so far. Then have the upper sealing groove Deformation of filling them with the same expansion slot width rubber seal or elastic sealing material, bury or pouring concrete surface with cement mortar smooth. 2, the tunnel plugging paste method: Deformation after grouting sealing, filling them with elastic sealing material can be pasted elongation in the cement mortar protective layer, high tensile strength synthetic polymer rubber sheet. Specific practices are: cement mortar protective layer to clean, requiring the grassroots level, dry brushing the grass-roots primary treatment agent, let it dry, and cut that grass-roots level on a good brushing supporting adhesive sheet, dry to refer When the touch stick, you can paste the polymer sheet. The trailing edge of the mat on both sides of the sheet metal layering pressure to shoot nails fixed, then at the edge of sheet metal on both sides sealed with caulk to form a multi-channel waterproof fortification.
