National toll-free 24-hour hotline: 13961999789 Business Service Hotline: 15862087268 The company has offices in the country: Eastern Region Northern Region Southern Region Central District, Northwest meet your company's needs, you can receive a call the day arrived at the scene to provide satisfaction... The construction program and product pricing. Willing to cooperate with your company happy, mutually beneficial and win-win. Pond seepage treatment program governance programs in engineering practice, expansion joints, settlement leakage is relatively common, due to cracks in the rubber water stop easily fixed firmly, pouring concrete when the regular shift, shift some serious, especially water stop difficult to fixed, when in-situ concrete Sealing lap easy to enter a small amount of concrete, resulting in overlap does not close; reinforced at the water stop unilateral shift; Sealing concrete sides and easy dense, often forming doghole, Honeycomb, hemp noodles. Taking into account the complexity of structure formation causes leakage, if leakage characteristics secluded location may appear, according to the project's functional requirements, structural features, we follow the "water engineering and technical specifications" required, the project adopted a "multi-channel fortification "" composite waterproof "," node seal "and other measures, selected varieties of waterproof material, to determine the structure and node approach, and propose appropriate technical measures program. It should be noted that this program is based on the construction unit to provide accurate construction drawings, construction units in accordance with the requirements of the construction drawings and related specifications, rubber water stop no serious damage, the development of this program can be achieved under the premise of the main functions. The actual situation of the project, for the outside of cesspools, we have designed a chemical grouting waterproof plugging and sealing compound waterproof sealant method for repairing cracks in concrete insufficient bearing capacity, in accordance with national regulations shall apply in addition to the method of repair In addition, there should be appropriate reinforcement reinforcement methods. For the inside of the cesspool, the use of low-pressure dispensing method (materials used for epoxy resin), surface waterproof sealant do embalmed (materials used for glass cloth). Lateral A. pool grouting principle chemical grouting waterproof plugging English full name is: Chemical Grouting, chemical grouting is a kind of counter-pressure water permeation grouting construction plugging new technology. Imported nanoparticles waterproof plugging molecule chemical agents with a variety of chemical raw materials mainly formulated into A, B two fluid, when the two liquids mix after polymerization reaction, the initial setting of 30 seconds, 2-3 minutes the reaction is complete, finally 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 soil particles and between the cracks together, so some effect of concrete cracks and pores closed improve the bearing capacity of the soil, to achieve complete sealing of the The purpose of the final in more than 20 years is no longer leaking; Sealing treatment outside of pool B. I can not remain stable in the current environment and working conditions based on the crack width, easy as a structural member of the force, deformation, or ambient temperature, changes in humidity and time sheets, crack when closed, can not completely eliminate their causes, but confirmation of the structure, security components does not constitute governance programs in engineering practice, expansion joints, settlement leakage is relatively common, due to cracks in the rubber stopper Hose easily fixed firmly, often shift when pouring concrete, and some displacement serious, especially fixed waterstops difficult, time-situ concrete Sealing lap easy to enter a small amount of concrete, causing the lap is not close; only Hose reinforced at unilateral shift; Sealing concrete sides and easy dense, often forming doghole, cellular, hemp noodles. Taking into account the complexity of structure formation causes leakage, if leakage characteristics secluded location may appear, according to the project's functional requirements, structural features, we follow the "water engineering and technical specifications" required, the project adopted a "multi-channel fortification "" composite waterproof "," node seal "and other measures, selected varieties of waterproof material, to determine the structure and node approach, and propose appropriate technical measures program. It should be noted that this program is based on the construction unit to provide accurate construction drawings, construction units in accordance with the requirements of the construction drawings and related specifications, rubber water stop no serious damage, the development of this program can be achieved under the premise of the main functions. When a hazard can be used with a resilient and flexible polyurethane grout repair. For the shape, size and number of cracks are no longer stable development, when patching, crack width only to surface sealing when using ω≤0.2mm, crack width ω> 0.2mm material when using polyurethane grouting repair.
