Anqing company specializing in plugging the unit welcomes your service hotline: 13961999789, sewer trench excavation depth, groundwater level due to higher construction area, pipe buried deep in the excavation of the sewer trench excavation conditions no grading When using steel sheet pile retaining playing straight trench excavation method of construction. Anqing professional plugging shutoff principle: The basic principle is that the chemical grouting water shutoff. Chemical grouting is the use of manual or mechanical means, under pressure, will be a special polymer material poured into cracks in the building structure, co-grouting cracks in the solidified material in order to achieve the purpose of filling and sealing of cracks. Water swelling rubber seal coating: Product Description: The water swelling rubber seal for a single component, solvent-free polymer sealant, has its own volume of the rubber elastic sealing and water expansion of the seal The double seal sealing mechanism for construction joints and various embedded components against leakage. Jiangsu-made company has a number of highly qualified professional divers, the past few years has repeatedly accomplished major tasks underwater plugging operations. I focus on companies in the construction quality, stress credibility, to comply with the contract, to ensure safety in the face full of opportunities and challenges for a better tomorrow, let us in a positive spirit and sincere cooperation, join hands! Anqing professional underwater plugging plugging company: Our company is the waterproof sealing technology research and development and construction in an integrated enterprise. With 20 years of construction experience, our company has been committed to Jiangsu waterproof sealing industry, providing customers with quality plugging Jiangsu, water and other services, the majority of customers. Chaoyang sewers underwater plugging plugging plugging cold welding skills is paying off: Today, many underwater plugging the company, not the same company during the hours of underwater plugging operations usually a great selection of different ways. Underwater cold welding plugging the development and use of skills, and achieved significant role in cold welding underwater plugging widely practiced skill occupations, the supply of safe and high quality service. After leaking sewers point away from the nozzle part, determine the location of the leak by checking the wells near the leak survey of all pipeline location, direction and depth of cases submitted to the Commissioner of excavation scheme, after examination and approval excavation, open After digging a reinforcing layer on the outside of the pipe leaks, the first pipe wrapped with the same material, surrounded by the king after plugging plugging State Lok Australia wrapped plastic film; with less permeable pipe in the trench bottom to the top of the range more than 50cm cohesive backfill soil stratification, clayey soil moisture content should be controlled within a range of ± 2% optimum moisture content, each compacted thickness of not greater than 20cm; 4, pipeline leak near the nozzle parts, using the drilling tool along Pipeline leak around drilling, underground injection grout sealing needle to use high-pressure grouting machine perfusion polyurethane grout slurry hole. Sewage pipe plugging plugging material to choose suitable varieties. Underwater engineering environment is very special, it is very humid environment, so choose a moisture-curing and ability of the material to absorb moisture, which can absorb moisture adsorption properties in order to achieve good adhesion. For through the cracks, you can take Sealing, pipe, algae slurry injection to crack steeple area, and thus can not eliminate the stress concentration area formed by the tip region, so treatment should carefully consider various factors, improving slurry filling rate . Depending on the circumstances of the leak, geological conditions, construction needs, reasonably determine the size of the excavation, and crossed range identification at the asphalt surface, and then cut with the cutting machine. Waterproof plugging process: ① concrete structure cracks leak: using pressure grouting, perfusion modified epoxy resin reinforced concrete slurry plugging in the reinforcement and construction of concrete epoxy mastic tree outside a closed deal. ② concrete structure Pock cellular leakage point: using pressure grouting, plugging perfusion modified epoxy reinforced epoxy mastic concrete reinforcement and construction of concrete outside the closed treatment within the slurry. ③ leaking pipe piece patchwork: using pressure grouting, perfusion modified epoxy resin reinforced concrete slurry and build epoxy mastic outside the closed treatment. ④ grouting hole plugging: ordinary cement mixed with waterproof plugging admixture. Anqing Jiangsu large professional plugging plugging plugging underwater project: basement plugging, plugging sewers, tunnels plugging, plugging cesspools, culvert trap, plugging the pool, with water plugging, plugging the dock mine plugging, cable channel plugging, civil air defense projects plugging, sealing joints, joint sealing, plugging cracks off, pump plugging, settlement plugging, plugging the dam, plugging underground works elevator shaft sealing, seam sealing engineering, cooling tower plugging, construction joints plugging, plugging and other underwater waterproof plugging works! Sewage underwater plugging plugging procedures as follows: According to leak water situation, find out the leakage point to the leakage point as the center of boreholes (diameter of 1-3 cm, 2-5 cm deep), and try to hole wall perpendicular to the base surface and rinse clean with plugging material twisted into the shape of a similar hole cone-shaped group, let it start to solidify at the rapid pressure inside the hole, holes in the wall to squeeze around the dense, so plugging material holes in the wall closely, when the inspection is completed without plugging leakages can be pressed with a polymer cement mortar to the board or wall flush. Jiangsu large plugging company has a number of high-quality professional divers, the past few years has repeatedly accomplished major tasks underwater plugging operations. I focus on companies in the construction quality, stress credibility, to comply with the contract, to ensure safety in the face full of opportunities and challenges for a better tomorrow, let us in a positive spirit and sincere cooperation, join hands! Professional plugging Anqing Company Responsibility: innovative efforts for the interests of customers demand attention plugging underwater construction safety, underwater plugging should follow the safety rules and do the following security measures:! 1 posts construction workers should wear work helmets, protective gloves, wear protective shoes. 2 chisel should be concrete and chemical grouting in addition to strengthening the field of ventilation. 3 should have custody of specialized technical management of irrigation fluid grout materials and manufacturing technology. 4 When conducting polymer grout, the operator should wear protective eyewear to prevent slurry spilled into the eyes. 5 build scaffolding to comply with the relevant safety rules, working at height to wear seatbelts. For through the cracks, you can take Sealing, pipe, algae slurry injection to crack steeple area, and thus can not eliminate the stress concentration area formed by the tip region, so treatment should carefully consider various factors, improving slurry filling rate . Anqing professional plugging plugging Jiangsu large company is specialized in underwater engineering companies, generally in underwater salvage. Tanmo underwater. Underwater cutting and welding. Caisson sinking and back cover with water. Underwater installation. Underwater inspection and repair. Underwater dredging. Plugging underwater diving and other services. I have a number of highly qualified professional divers, the past few years Jiangsu large plugging company has repeatedly dive to complete the task of major, I focus on companies in the construction quality, stress credibility, to comply with the contract, to ensure the safety of these projects is Our company has won high praise and convincing large units. The company's business allegiance purpose: to excellent diving, first-class technology and equipment, quality of service quality, efficient service efficiency, enthusiastic attitude, based on the national market, the Yangtze River Delta region for all customers with a full range of quality diving services .
