Has over 30 years of construction experience, in recent years, the introduction of foreign advanced technology and high-performance waterproof plugging special hydraulic grouting equipment, imported high-tech nano micro molecules waterproof materials, preparation of scientific precision grouting plugging new technology buck and efficient block technological innovation, professional management of various underground leakage joints, especially for mass concrete cracks, tunneling, settlement leakage has many years of experience in maintenance treatment, complete with tough waterproof plugging ability, is close to plugging your experts! Construction performance throughout the country. Molecular grouting waterproof plugging nanoparticles new technology is suitable for the following types of projects: culvert, settlement, expansion joints and Deformation, back strip, construction joints, cracks off the bottom of sewage leaking water waterproof plugging grouting repairs . Underground base construction, underground engineering, civil air defense projects, bank vault, floor and other concrete structures pond water leakage plugging construction. Mine access, wellbore, caisson, dam, bridge, roof, tunnel, culvert, drainage works take leakage shutoff maintenance. Coal mine coal handling system, threading pipe, casing, coal handling bridge, drilling, well Wall, tailings leak sealing cracks in concrete culvert. Cable trench pit, cable tunnels, cable wells, elevator shafts, wells siphon valve shafts, foundation pit engineering leak water, with water plugging operations construction. Basements, underground garage, parking, underground passages, heat pipes, excavation, shaft and other types of underground works plugging leaks repair and construction. Concrete structures, cooling towers, cooling towers, chimneys fouling platform, through the pump house, plumbing, sewage treatment pond seepage water trap maintenance works. Highway tunnels, tunnel, tunnel across the river, artificial lakes, water tunnels, the railway tunnel leak plugging cracks in mass concrete. Dock cofferdam water conservancy and hydropower projects, lock works, pumping stations, hydropower stations, reservoirs, dam grouting cracks in concrete reinforcement. Tunnel leaks can be divided into the following types: (1) tunnel tunnel leak leaking handle processing subway tunnel leaks processing Yangtze river tunnel leaks treated railway tunnel leak leaking handle handle handle the extent of road tunnel leak leakage can be divided into the following situations : (1) microdialysis: concrete surface moist, wet stains, hand touching water, no water stains reflective light irradiation. (2) slow infiltration: wet concrete surface, a watermark, hand touching water, dry seepage area, after a period of time can be seen imprinted reflective water. (3) Leakage: leakage dry surface, there is immediately visible on the water seeping leaks, drips or drip into a line under the roof, walls Tangshui form water on the floor. Leaking large individual was small halter shape, leaking 50ml / min. Reason analysis and repair leaky tunnel besides abundant groundwater, the main tunnel caused by improper design and construction. Such as the lack of the lining surrounding groundwater water, water, water quality investigation and analysis designed for waterproofing and drainage thoughtless, structural corrosion resistance, cold, impermeability nor for special design. After the tunnel construction, the groundwater near the mountain will become the channel through the gathering. When the tunnel surrounding aquifer connectivity, and the lining of the anti-drainage is imperfect, inevitable tunnel leaks diseases. Tunnel through the aqueous formation. Such as through the sandy soil and the soil type drift gravel aquifer; jointed and fractured fault zone containing rock crevice water; limestone, dolomite and other soluble rock, there are water-filled cave or underground river, such as when communicating with the tunnel; lots of shallow tunnels, cracks along the overlay surface water infiltration into the tunnel. Comprehensive flood control facilities, inadequate tunnel lining or failure in a long time. Originally built as a tunnel lining waterproofing and drainage equipment failure, there is a tunnel lining behind the water or confined water; poor quality of construction of concrete lining, pore cracks more, their water is poor; waterproof layer (inner-adhesive, posted outside or intermediate mezzanine) poor quality of construction, or materials, poor durability; working joints of concrete, expansion joints, settlement and other joints mishandled or well water treatment; lining deformation, cracks leaking water after etching; both drainage equipment, such as Ditch lining behind the blind ditch, no auxiliary tunnel lining, drainage holes and other disrepair blocked. Plugging the tunnel seepage water treatment programs to address leaks also set three options: block / block / block row of the collection, the method of plugging into the traditional methods and chemical grouting methods. 1, the traditional method of plugging is to cracks or leaks drilling, surface sealing, but the result is often blocked here, there began to leak. Because water can not rule movement in concrete internal cracks, leaking from a relatively weak position. 2, generally refers to chemical grouting material prepared by chemical slurry grouting mouth buried by drilling, the use of pressure injected into cracks in the structure, so that the diffusion, coagulation, to waterproof, sealing, reinforcement, reinforcement purposes. Commonly used in the repair of concrete structures deep cracks. According grouting pressure and speed can be divided into high and low pressure grouting method to quickly slow grouting method. Currently, chemical grouting method has been widely used in dam foundation, foundation reinforcement and seepage, leaking underground engineering Yangtze River Tunnel treatment, the Yangtze River tunnel plugging - Yangtze River Tunnel trap - concrete bug fixes, and many other engineering fields. 3. joints leak water, should tick along the pipeline into the groove joints, clean, filled, sealing materials, with quick-setting packer plugging material buried in the annular groove, perfusion polymer chemical grouting material block leak sealing; no leakage inspection after filling them with sealant and leveling polymer cement mortar and set flexible waterproof coating layer. Patented technology: Polymer waterproof plugging filling introduce a performance to a variety of imported chemical materials formulated into A, B two fluids, according to the construction of water pressure is almost the size of the ratio of the viscosity of water into the same liquid, permeability, energy injection of 0.1 mm slit in the concrete under pressure and very humid environment quickly gather. 2, setting time can be accurately controlled with the ratio within a few seconds or minutes, rapid condensation of pressure in the water velocity, water flow and more cases. 3, good permeability, water swelling after drying shrinkage, insoluble in water, kerosene, gasoline and other organic solvents, acid, alkali, bacteria Erosion from atmospheric conditions also after, there is a certain strength, flexibility and change pressure, with a particular high-pressure grouting equipment, seepage into equal parts, so that the soil through cracks between the particles together, and some closed-efficient concrete cracks and pores to improve the bearing capacity of the soil, and ultimately shelf using ten In the above is no longer leaking, so as to achieve the purpose of completely sealing, eliminating leaks construction companies and owner of worry! 4, tensile strength, Construction had been plugging the crack mouth, and later appeared normal settlement or dislocation cracks also no leakage. I would like to sincerely cooperate with all friends, and common development, mutual win-win situation, and warmly welcome all enterprises and individuals to negotiate.
