Shaft Seal - Shaft trap - the shaft sealing leaks also three options on how to close the processing set price: 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, underground tunnel excavation, concrete bug fixes, and many other engineering fields. 3. leakage of water, should be from the positive side along the pipeline trench around the tick into the ring, cleaned, filled, sealing materials and polymer cement mortar leveling, 250mm range of facilities to do flexible waterproof coating layer. 4. Can not the case of the positive side of governance, from the dorsal surface of the water along the pipeline into the ring groove around the tick, clean, with a 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. 5. The joints should be filled, water expansion of the seal. Above the main building for water leakage case I am using imported nanoparticles molecule chemical raw materials waterproof plugging agent formulated with a variety of chemical materials A, B two-fluid, when the two liquids mix after polymerization reaction, 30 seconds early condensate, 2-3 minutes the reaction is complete, the final cemented colloids. Grouting injection structure layer using a water-soluble form, low slurry viscosity, permeability, can be injected into the cracks of 0.1mm or less; slurry in the wet, the water speed large, multi-criteria aggregation under water; gel also has good permeability, the case expansion of water, corrosion resistance and other characteristics, colloidal compressive 0.01-0.06MPa, tensile strength 0.02-0.04MPa. With a particular high-pressure grouting equipment, seepage into equal parts, it runs through the cracks and soil particles together between some concrete cracks and pores closed efficiency increase the carrying capacity of the soil, and ultimately more than 20 years without then leakage, so as to achieve the purpose of completely sealing, eliminating leaks construction companies and owner of worry!
