Tongxiang elevator shaft plugging plugging specialized units hotline: 13961999789 Jiangsu large waterproof plugging Engineering Company - China waterproof plugging a must is the construction with water plugging technology research and development in an integrated enterprise. The company specializes in the application and promotion of anti-pressure grouting plugging nanometer technology, Tongxiang elevator shaft plugging company has 40 years of construction experience, equipped with advanced plugging waterproof construction machinery and equipment, to help enterprises solve the problem of water leakage worries, trust unit is waterproof plugging works! The technological achievements for the majority of companies have made significant economic, social and environmental benefits. Causes of the elevator shaft and repair water leakage 1. Elevator shaft leakage causes (1) lift and negative angle four weeks severe leakage reason: because the floor do first waterproof layer. Then cast concrete wall sidewall, this has led to a concrete wall with the side wall of the elevator shaft bottom fault. Construction on the original waterproof layer waterproof effect should not play, so it will continue from groundwater seepage into the elevator shaft at fault. (2) civil construction, a lot of water has not drained the floor, drain, and directly to the concrete is poured into water, causing the floor surrounded by a lot of cellular, Ma surface, holes, loose sulfur. The transfer is not tight and the bottom, the bottom of the elevator shaft in position under the water line plus or minus zero 3m, groundwater pressure greater groundwater through holes, pockmarked face, cracks and loose at the leak to the bottomless pit, causing the elevator shaft water. (3) the shaft wall of water leakage reasons: because of the elevator and the wall (correct me well sidewalls negative zero to the pit below the horizontal plane around the training) divided into two cement mortar surface. And the inner and outer side walls of the elevator were not for water treatment, groundwater from wells cases wall facades penetrate into the wall of the elevator shaft and cause hydrocephalus. Elevator shaft leakage deal also set three options: block / block / block row collection 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 heating pipes leaking wells treatment - heating pipes plugging wells - wells trap heating pipes, concrete bug fixes, and many other engineering fields. 3. Secondary pouring seam leakage of water, should tick into the groove along the inner gap, clean, filled, sealing materials, with quick-setting packer plugging material buried in the trench, perfusion polymer chemical grouting material plugging sealing; no leakage inspection after filling them with sealant and leveling polymer cement mortar and set flexible waterproof coating layer. Above the main building for water leakage case I am using imported nanoparticles molecule chemical agents and waterproof sealing materials formulated into a variety of chemical materials A, B two-fluid, when the two liquids mix after polymerization reaction, 30 seconds initial set, 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! I would like to sincerely cooperate with all friends, and common development, mutual win-win situation, Tongxiang elevator shaft plugging company warmly welcome all enterprises and individuals to negotiate.
