The construction program and product pricing. The company is willing to cooperate with your happy, mutually beneficial and win-win. Basement 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 securely, often shift when pouring concrete, and some shift serious, especially water stop Fixed difficult when situ concrete water stop lap easy to enter a small amount of concrete, resulting in overlap does not close; reinforced at the water stop unilateral shift; and water stop on both sides is not easy compacting concrete, often forming doghole, Honeycomb, Ma noodles. Taking into account the complexity of structure formation causes of leaks, if possible leakage characteristics appear secluded location, according to the project's functional requirements, structural features, we follow the "water engineering and technical specifications" of the requirements, 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 practices and propose appropriate technical measures program. It should be noted that the present scheme is based on the construction drawings provided accurate construction unit, construction unit 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 outer cesspool, we designed a chemical grouting waterproof plugging and sealing compound waterproof sealant methods for bearing capacity of less than patching cracks in concrete, in accordance with national norms should be applicable in addition to the method of repair In addition, there should be appropriate to reinforce reinforcement methods. For the inside of the basement, the use of low-pressure dispensing method (materials used for epoxy resin), do the sealant surface water corrosion treatment (the material used for glass cloth). A. principle of grouting outside of basement waterproofing chemical grouting plugging English name are: Chemical Grouting, Chemical Grouting is a kind of counter-pressure water permeation grouting construction plugging new technologies. Imported nanoparticles molecule chemical raw materials mainly waterproof plugging agent with a variety of chemical materials formulated into A, B two liquid when mixing two liquids after the polymerization reaction, the initial setting of 30 seconds, 2-3 minutes the reaction is complete, finally cemented colloids. Grouting injection structure layer using water-soluble form, low slurry viscosity, permeability, can be injected into cracks 0.1mm or less; slurry in the wet, the water speed large, multi-criteria under water condensation; gel also has good permeability, the case Water expansion, corrosion resistance and other characteristics, colloidal compressive 0.01-0.06MPa, tensile strength 0.02-0.04MPa. With a specific high-pressure grouting equipment, seepage into equal parts, it runs through the cracks in the soil between the particles together, thus closing some effect of concrete cracks and pores improve the bearing capacity of the soil, to achieve complete sealing of the purpose, culminating in more than 20 years is no longer leaks; B. Sealing treatment outside of the basement I can not remain stable in the current environment and working conditions in accordance with the crack width, easy with the force structure member, deformation or ambient temperature, changes in humidity and time sheets, crack when closed, can not completely eliminate its 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, when pouring concrete often shift, shift some serious, especially with a difficult fixed water only when the water stop lap situ concrete easy to enter a small amount of concrete, resulting in overlap is not closely; Sealing reinforced at the unilateral shift; and easy-compacting concrete water stop on both sides, often forming doghole, cellular, Ma noodles. Taking into account the structural causes leakage of complex formation, if the leak is now possible hidden location characteristics, according to the project's functional requirements, structural features, we follow the "water engineering and technical specifications" of the requirements, the project adopted a "multi-channel fortification "," composite waterproof "," node seal "and other measures, selected varieties of waterproof material, the Construction and nodes to determine practices and propose appropriate technical measures program. It should be noted that this scheme is based on the construction drawings provided accurate construction unit, construction unit in accordance with drawings and related specifications require the construction, rubber water-stop no serious damage, to achieve the development of the main functions of the premise program. When a hazard can be used with a resilient and flexible polyurethane grout repair. For the morphology, size and number of cracks are no longer stable development, when the repair, only to be closed method using surface crack width when ω≤0.2mm, crack width ω> 0.2mm when using polyurethane grouting material repair.
