Underground tunnels waterproof plugging plugging Hotline: 13961999789 professional company to undertake professional: basement plugging, plugging the tunnel, cesspool plugging culverts trap, plugging the pool, with water plugging, plugging the dock, mine plugging, Pressure Seal, 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. The company's patented technology: "Polymer waterproof plugging technology." The company uses professional waterproof anti-corrosion materials manufacturers and a number of national research institutions for many years developed techniques to a variety of imported chemical materials, according to the construction of water pressure is almost the size of the ratio of the viscosity of water into the same liquid, good permeability, can be injected 0.1 mm slit in the concrete under pressure and very humid environment quickly gather. Setting time can be accurately controlled with the ratio within a few seconds or a few minutes in the water speed of pressure, rapid condensation of water flow and more cases. Good permeability, shrinkage after swelling with water, insoluble in water, kerosene, gasoline and other organic solvents, acid, alkali, bacteria erosion will also affect post from atmospheric conditions, there is a certain strength, elasticity and transformer, Shelf use more than a decade. Tensile strength, Construction had been plugging the crack mouth, and later appeared normal settlement or dislocation cracks also no leakage. The key is to waterproof plugging cracks leak handling, based on the reasons for the occurrence of cracks and the extent of the impact of the structure, etc., the following actions were taken: 1. Surface treatment: according to the site where the cracks, can cement mortar, fast-setting waterproof surface cracks parts epoxy mortar and mortar smear, stick up, repair and other embedded complement and shotcrete. 2. Internal Processing: For shallow seams and cracks just seepage, and generally available cement grout, such as off the flow rate of less than 0.3mm or greater penetration and cracks affected by temperature changes, chemical grouting treatment should be used. 3. Structure processing combined with surface treatment: for cracks or damage affecting the integrity of the structural strength of the building, in addition to taking the internal processing, but some still need to take measures to deal with the structure of the binding surface treated to achieve the anti-seepage, structural reinforcement or restore integrity requirements. 4. Around the infiltration process: should find out the geological conditions and leakage of parts of the building on both sides, to take appropriate measures to deal with. Its treatment methods, there are backfill excavation, drilling, grouting and deepen tooth wall. 5. Sealing, structural joint seepage treatment: concrete sealing, structural joints leak repair of buildings, first consider the use of hot asphalt supplemental irrigation. When supplemental irrigation is difficult or ineffective pitch, you can use chemical grouting. Polyurethane grouting material available when using single liquid filling method, the equipment is simple, easy construction. In addition, they are often high, high pressure slurry. 6. Foundation seepage treatment: a comprehensive analysis should be carried out in accordance with reason, the base case and construction conditions leakage, determine treatment options. For non lithology basis, can be done in the upstream blanket building clay, clay or clay cut-off wall grouting and chemical grouting and improve drainage conditions and other downstream; batholith of leakage, and can be taken to deepen thickened water blocking curtain, curtain grouting reinforcement and additional downstream drainage holes, improving drainage conditions. 7. San seepage or leakage of centralized treatment: concrete buildings of the seepage or leakage of centralized reasons, mainly due to the honeycomb, empty, not dense and low defect caused impermeability grade. Compacting concrete for building interiors, poor fracture porosity is relatively concentrated area, available cement and chemical grouting; for a large area of ??fine loose-head infiltration and smaller parts of the surface can be coated way; for concentrated jet holes, the flow rate is not can be used to plug holes quickly after cutting hair gel mud. Such as flow rate greater, to use cotton or flax wedge holes to reduce the flow rate and reduce the amount of leakage, and then the blockage. The company will be advanced technology, scientific management, excellent construction team, quality service, and strive to quality and excellence. Reputation and promote development, is willing to establish various forms of partnership with friends.
