Expansion joint plugging construction Project: 1, in accordance with your description and analysis on the phone, your organization construction joints leakage water, combined with our company for many years now concrete waterproofing, sealing the successful experience, a special set of feasible fix The construction program for the owners reference. 2, the general causes and concrete seepage leakage cause harm 2.1 2.1.1, concrete because concrete (or mortar) in the construction of vibrating untrue, compactness caused by poor local cellular, holes and other defects. 2.1.2 by temperature stress, affect the shrinkage stress, concrete forming irregular leakage of water channels. 2.1.3, joints leakage: As in the construction, there is deviation placed stop, or sedimentation rate is too large, pull off the stop, resulting in leaking joints. For these various reasons, resulting in concrete seepage water, it can not work according to the original design requirements. 2.2 concrete seepage hazards a. Leak water, calcium hydroxide will dissolve the presence of reinforced concrete interior loss, PH value becomes small, easily lead to the occurrence of reinforced concrete structure corrosion, and will speed up the construction of concrete alkali aggregate reaction, thus affecting the structural safety and shorten the life of the project. b. Severe leakage, not only affect the normal use, but also seriously jeopardize the foundation bearing capacity of concrete body and surrounding buildings. c leaking water may cause electrical insulation performance of the equipment and affect safety, could easily lead to the wall affiliated iron corrosion damage. 3. Comprehensive Treatment of concrete seepage water leaking joints: joints inside the first foam ointment or other fillers to clean water stop the expansion joints in the joints with water to wash after catchy power hammered edges. clean. Joints filled with flax close to about 5 cm. Then fill the joints with water will not leak. Embedded grouting mouth filling expansion joints in the process. A grooved surface and wiping material plugging effect and a very close relationship, materials for sealing technology provides the basic conditions and play a security role, superior performance, high-grade material is ultimately reflected in the use of technology, no matter what material it Be sure to match the plugging technical operations, to adapt. Therefore, this project waterproof, plugging the selection of materials as follows: preparation and production of special fast-setting, the expansion of plugging plugging polymer materials for repair; select leaking maximum leakage points extended to both sides of the center, with the impact hammer or artificial hewn V line groove, catchy 6-10㎝ width, depth 6-10㎝, V bottom cracks, V trekking into the φ0.5-1 diameter hose after use (bail) were evacuated and buried plaster grouting hole. Grouting hole spacing 80-150㎝, ensure grouting holes are superimposed radius. Second, laying packers: packers with 4-6 PV pipe or cast iron pipe, buried line tank, clean, with a double fast or high-grade cement to cement grouting mouth firmly in line groove, the depth is not less than 2-4㎝. Third, the leaking portion of the closed mouth buried grouting, grouting mouth except water leakage, the other where there is water leakage or possible leakage sites (within limits) should take containment measures in order to avoid leakage of plasma, running plasma phenomena. Fourth, after a closed trial Note leaks packers buried and having a certain strength. When testing with color instead of an aqueous slurry injection to calculate grouting, grouting time, provide a reference for determining the slurry mixture ratio, grouting pressure. While observing the situation and plugging the holes in communication, so as to ensure the normal grouting. Fifth, installation and inspection of the installation and inspection of grouting equipment to ensure safe use in grouting construction. Sixth, grouting hole grouting choose one (select a larger packers and leaking at the lower amount), to be porous to see Pulp, immediately shut down the wells, continue grouting, grouting pressure should be greater than the leakage water pressure, the slurry along the seepage channel 迸 to advance, until no longer into the pulp, to immediately shut down then stop grouting packers. After the grouting, the grouting holes and inspection hole plugging dense. After the slurry is solidified, removing packers, grouting plugging effect was observed, grouting can be repeated if necessary. 3.1 Governance Principles first part of a major defect holes, loose and other serious leakage of water from the entire concrete wall carefully to find treatment. This step is the key to the whole plugging, must be carefully, carefully carefully take the trouble to do a good job. Only on this basis can be carried out on the second step of plugging processing. Plugging effect and material relations are very close, materials for sealing technology provides the basic conditions and play a security role, superior performance, high-grade material is ultimately reflected in the use of technology, no matter what material it must be with the sealing technology Operating match fit. Therefore, this project waterproof, plugging the selection of materials as follows: preparation and production of special fast-setting, the expansion of plugging plugging polymer materials for repair. 3.2 Basic principles 3.2.1 plugging plugging construction principle is the chemical grouting plugging. Chemical grouting is the use of manual or mechanical means, under pressure, will be a special polymer material poured into the cracks in the building structure, combined grouting material solidifies in the cracks, in order to achieve the purpose of filling and sealing of cracks. For through the cracks, sealing seam can be taken, buried, algae slurry injection into cracks in the steeple area, and thus can not eliminate the stress concentration area formed by the tip region, so treatment should be carefully considered a variety of factors, improving the slurry filling rate . For temperature crack, taking into account the temperature of the concrete construction of the "lag effect" generally choose low temperature of the concrete grouting process better. 3.2.2 polymer grouting material advantages a. Polymer grouting material groutability, gel time can be adjusted as needed. b. polymer after curing shrinkage grouting material, and concrete bonding better performance. c. Polymer consolidation grouting material body has a certain compression tensile strength, good durability and stability. d. Polymer grouting material safe operation, convenient, simple pressure injection equipment. 3.2.3 Summary of grouting Grouting is a new chemical grouting plugging technology, which uses double grouts. Proportionally weighed three materials add water and stir into solution A, according to the proportion of Sulfur weighed add water and stir into solution B, when the two liquids mixing occurs after the polymerization melon, the initial setting of 30 seconds Table 2-3 minutes melon complete, end cemented colloids. Rock grouting injection using water-soluble form, low slurry viscosity, permeability, can be injected into the cracks under 0.1mm; slurry in the wet, the water speed large, multi-criteria aggregation under water; gel also has good permeability, water expansion, corrosion resistance and other characteristics, colloidal compressive strength 0.01 ~ 0.06MPa, a tensile strength of 0.02 ~ 0.04MPa. The method by grouting plugging into the water beyond the masonry, so as to solve the pond leakage. 3.2.4 Grouting end standard considerations of surface leakage if water has effectively block principle. Technical measures to ease the closure of grouting: hole in the cloth should consider the existing grouting plugging leakage of water, should be carried out in the grouting grouting grooming, which is to inject the slurry, when leaking water there gradually changed overflow pulp slurry concentration, adjust the slurry gel time, so to divert water leakage at the sealing by grouting from the inside out. If grouting part leaks can not achieve the purpose of the overflow slurry, then a leak point bore grouting, so as to achieve a slurry filled from outside to inside and closure. 4. Machinery high-pressure grouting machine, impact drill, lighting equipment, hardware tools (Pliers, adjustable wrench, chisel etc.), Mason Tools (fender, scraper, etc.) and other tools. 5. The construction quality assurance by our unit construction plugging leaks had no leakage, seepage. If found blocked off the site leaks, seepage problems, I own expense repair block, the warranty period is 5 years. 6. Construction Safety 1, to participate in the construction of the installation work must be familiar with the operation of skilled, technical supervision departments issued a "special operations personnel to operate card", so certificates, a strong sense of self-security, the establishment of a full-time security officer, promptly eliminate safety hazards, construction workers strict compliance with safety rules, Prohibit illegal operations; 2, responsible for the pre-construction work must be detailed before the mounting process, the construction of relevant technical requirements of the construction start good job ticket, make the relevant quarantine measures; 3 workers must wear seat belts, non-slip shoes, if necessary, to set the fence, fence and other security measures; 4, the construction site should be away from flammable, toxic gases, pressure from cable and other dangerous places, if not more dangerous to leave the place, Party required to provide safety measures and special protective equipment; 5, all construction workers to draw attention to their safety and proper construction, to carefully obey the command of field commanders to work, construction workers are not allowed to unexplained circumstances for processing; 6 problems encountered in the construction to be found in time to report to the commander, in case of special circumstances, by the field commanders report to the chief commander, obey treatment, then the next step of work; 7, the construction site, must wear safety helmets, to supervise the work in each other their own safety and construction acts to ensure that no brutal construction, to be responsible for the work; 8, all staff during operation, must wear helmets, the job should be tools used in relatively safe location. Staff should absolutely avoid in the lower area of ??high-altitude operations for construction. 7.
