Plugging plugging leaky sewers Hotline: 13961999789 Jiangsu large altitude Engineering Company Limited (Headquarters) large waterproof plugging new offices welcome you to inquire! ! ! Jiangsu large waterproof plugging Engineering Co., Ltd. is a specialized waterproof construction enterprises, honest, trustworthy, unity and progress of our codes to the quality to win the trust of users, in good faith to serve the community is our aim. Leakage is a major factor in building long-term impact failure of important architectural features to play, while giving users a lot a lot of unnecessary trouble, for which people feel headache Left, acquaintance is the edge, we will be excellent products and quality of service in our sincere efforts in rainy day to prop up your party skies, our long-term undertaking all kinds of waterproof construction, new large waterproof plugging Engineering Co., Ltd. is a professional water treatment drain body. A professional manufacturer of waterproof material backing for the point, there are a large number of rigorous professional, with extensive experience in water treatment technician for relying leak. There are a huge drain governing professional waterproof construction team for support. First, the construction area: 1, highway crossing the river, the railway tunnel construction settlement, expansion joints, cracks in the bottom leaking water waterproof plugging construction. 2, the underground base construction, underground engineering, civil air defense projects, such as sewage treatment pond water leakage plugging construction of concrete structures. 3, basements, underground garages, underground passages, heat pipes, and other types of underground seepage pit plugging construction. 4, pool, cable channel pit, mine access, elevator shafts, foundation pit construction joints plugging leakage of water with water-construction. 5, concrete structure, cooling tower circulating cold water channels, pipes, sewage treatment pond seepage water corrosion plugging the construction project. 6, culverts, caisson, pump house, dam, bridge, roof, tunnel, take control plugging leakage of water drainage works construction. 7, hydraulic reservoir dam grouting, plugging cracks in the tunnel, seepage, cracks in concrete dam seepage 8, coal mine coal handling systems, coal handling bridge, drilling, well Wall, borehole concrete cracks leak water plugging reinforcement. -------------------------------------------------- . -------------------------------------- grouting concrete construction steps a surface treatment: the crack about 10cm of concrete surface treatment and clean, and the water to find the location of the gap. . b slotted or drilled: in seepage around each 3cm gap by cutting machines at 6-8cm deep seam preparation for gouges. c 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. d 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. . e grouting: After 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. . f swabbing leveling: waterproof mortar reaches a certain intensity, wet the repair area, brush 1: 2 ordinary mortar, thickness 0.5-0.8cm. g conservation: for 3 days in water conservation principles grouting point drain water injection grouting to the smaller, the greater after injection; the next ring to crack up sequentially by grouting; horizontal or diagonal cracks smaller end by water the larger end of grouting; surface leakage from the periphery to the center in order grouting. Grouting end standard considerations of surface leakage if water has been 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.
