Jiangsu large plugging Engineering Co., Ltd. is a professional undertaking waterproof plugging construction companies. The company has first-class technical experts plugging engineering, construction management, advanced technology and construction technology professional construction team. The company dedicated to the research basement, tunnels and other architectural brick concrete structure of water leakage and other issues, specializing in the promotion and application of nano-technology, anti-pressure grouting technology to help you solve the problem of water leakage worries, the company conscientiously implement the ISO9001 -2000, GB / T19001-2000 international quality system standards, through a comprehensive safety, quality, occupational health and safety management system certification three. Construction of the project first inspection pass rate of 100% user satisfaction with the commitment of 100%, won consecutive years in recognition of superior unit. Please call the detailed program and quotes! Basement plugging construction measures in accordance with the importance and use of the basement plugging in engineering requirements, determine the level of basement plugging underground works, for different parts of the project a "defense, row, cut, blocking" the combination of hard and soft and economic, local conditions, comprehensive way. 2.1 Anti-row combination of underground excavation using cement mixing pile retaining wall supporting gravity to form a seal around foundation curtain, and by precipitation design, arranged in a deep foundation pit precipitation points. Before basement excavation of earth, water pump started well group precipitation, making plugging in the underground basement concrete construction process, the water table remains in the basement plugging layer below 30cm. Surface water into the pit around the trench around the next to ensure that the structure of the basement in the basement with no water in mud plugging construction during construction. 2.2 determine the rigid basement plugging basement plugging basement concrete impermeability grade of concrete structures using self basement plugging UEA shrinkage-compensating concrete pumping, UEA mixed lot of 8% to 10% of cementitious materials. UEA limit expansion of 2 ~ 4 × 104-4 concrete strength can be increased by 10% to 30%, 2-fold increase impermeability, frost resistance, resistance to sulfate is also greatly improved, no corrosion of steel role There are advantages retarding effect can compensate for the temperature difference between concrete shrinkage, then mixed with water reducing retarding compound used is one of the best measures to reduce the large volume of concrete cracking, it can effectively suppress internal porosity of concrete, increase the density of the interface, so as to achieve the purpose of plugging basement. (1) large volume concrete foundation of integrity requirements, and therefore should be layered pouring concrete, layered vibration (generally 30cm ~ 40cm). 2.3 Flexible basement plugging basement plugging cement-based paint requirements grassroots level, clean, moist, have sufficient strength, yin and yang make rounded corner. Liquid and powder materials by 1:1 ratio and stir after use, with a good paint should be used up; the construction sequence for the first corner of yin and yang, such as an additional layer of detail enhancement processing node, then the facade construction. Construction, if too dry grass roots, rendering a material dilution required, the first pass coating should be thin, even when you need to coating. Usually 3 to 5 times the amount of (3 ~ 5) kg / m2. After the first pass coating is dry, the coating can be carried out a second time, the second time the coating direction should be perpendicular to the first pass. After various times and so on, until the coating thickness of 1.5mm. The coating composition containing cement, cement bonded easily with class material, therefore, can be protected in this coating layer of cement mortar construction, masonry materials, direct, subject to plugging in the basement after layer of hard work carried out. After completion of the basement wall basement plugging treatment, pit and the exterior space using cohesive backfill soil to change the environment, within the pit artificially reduce soil infiltration capacity, thus achieving the basement sealing purposes. After pouring the basement plugging with 2.4 after treatment with the concrete poured concrete with a part of the second phase of the concrete junction, basement plugging function in the weak parts, very easy to cause leakage, particular attention. Therefore, in order to prevent the emergence of vertical cracks in the foundation of the original design, and the other to increase the number of stretching after pouring belt to ensure that after pouring belt around 30m ~ 40m each set together. After pouring the thickness of the middle set with a long pass enclosed steel water stop, fully welded joints, after pouring belt to improve the quality of basement plugging. After pouring concrete at the front with the construction, the first wooden mold or fine wire mesh sides removed, clean the surface relatively loose concrete, surface roughening, moist than 48h, and check whether the leakage of plasma template. After pouring belt should be added at once basement plugging paint, according to design requirements and after pouring the floor with a layer of 100 shall also additional 1.4m wide concrete thick cushion inside with Φ 12 @ 200 bi-steel mesh. After pouring the concrete and construction interval situ concrete sides at least 2 months. After pouring concrete construction temperature should be lower than the temperature at both sides of the in-situ concrete construction, which is to reduce the temperature gradient inside the outer layer of concrete and concrete between the cracks due to shrink to reduce distortion arising under restrictions, effective After pouring with construction quality assurance. After the final setting of the concrete cover and water conservation were sacks, curing time is generally not less than l4d. The company specializes in plugging construction, 40 years plugging brought together a group of professional personnel. Professional undertaking: 1, basement sealing, basement garage construction joints, expansion joints seepage plugging. 2, large dock plugging, wall construction joints, cracks off, water leakage plugging floor joints. 3, tunnel plugging, subway settlement joint, joints, construction joints, cracks off water leakage plugging. 4, the cable channel plugging, slim pit construction joints, cracks off leak water, with water pressure plugging works. 5, cooling tower plugging, cooling tower circulation channels, cesspool plugging water leakage corrosion. 6, caisson, pump house, dam tunnel, take the drainage project, a large area of ??water leakage plugging. I adhere to the people-oriented, follow the "quality first, the owners first, abide by the contract, quality service," the purpose, regular visits! Rambling waterproof plugging company welcomes you
