Examination and treatment of the base surface (1) Base surface inspection: Under the terms of the national standard GB50212-2002 of the cell body Concrete / cement mortar base surface for acceptance, including: l visual concrete surface, must be strong, dense and free of grease, no shell, sand, cracks, shelling, Honeycomb and so on. Grassroots yin and yang angle should be made rounded. l strength must be tested and meet the design requirements, with a small hammer beating the grass, check strength meets the design requirements (without hollowing phenomenon). l cell body after conventional grass-roots conservation must be dry, 20mm in thickness containing deep water of not more than 6% (grass surface whitening). l surface flatness with a 2m straightedge and a wedge feeler, the allowable deviation of not more than 2mm. l Non groundwater seepage, uneven subsidence. Cell body concrete layer must have waterproof barrier. (2) the base surface treatment l mouth with a chisel hammer, shovel, angle grinder and other tools to remove the soft surface of the residual cement and slag grinding template seams, cleaning dust. l use of a small amount of oil pollution at a solvent such as scrub, until the contaminant is removed, the solvent to evaporate; grinding tools can also be rubbed off. l raised at the local partial polished floor, a small number of partial cracks open with a chisel (V) groove, the resin mortar repair material slowly poured along the cracks, compaction polished. l pollution at oil, asphalt and other available flame baking shovel. l Where through the pipeline coating and casing, aside hole, embedded parts, should be set in advance or remain buried. 2. Xiamen fiberglass repair process construction elements (1) l primer on the pool body construction concrete base, first base material evenly brushing a request shall holidays, so the primer penetrate the grass roots to ensure fiberglass combined with the grass roots firm. l The Nature Conservancy time should be greater than 24 hours, it is dry, if uneven depressions at the clay required to fill the flat only after the next process. (2) the continuous isolation layer construction method used in this project, as follows: l have to lay on the bottom of the grass-roots evenly brushing a layer of rubber lining, then lining the first layer of cloth, a net to catch the bubbles. l posted solid lining after brushing a layer of rubber, plastic materials should not be too much to soak up the cloth. Followed by a second layer of fabric lining again. l Puwan even after brushing a second level layer of layered compound, and spread a layer of uniform particle size 0.7-1.2mm rare quartz sand. When l lining, with layers take the slit width of not less than 50mm; upper and lower seams should be staggered, staggered a distance of not less than 50mm, yin and yang corner should be increased by 1 to 2 layers of cloth. (3) binding layer l rata requirement formulated resin mortar, a formulation should be based on the construction circumstances, not too much. l paving resin mortar shall meet thickness requirements. l construction should be carried out after the isolation layer is cured. (4) The former granite masonry block material surface layer l use, selection, cleaning, drying spare. l paved preceded test row. When paving, paving the order from low to high, the first trench, after the ground, dado. Yin corner facade pressed flat, Yang corner flat pressure elevation. Staggered joint arrangement should be, there should not cross through the seam. l bonding layer and mortar joints should be full of dense, strong adhesion. Mortar joints smooth surface. (5) Xiamen fiberglass repair and maintenance: The Nature Conservancy time is 7-14 days, must be fully cured resin mortar and clay and can be put into use after confirmation. Third, other requirements 1. The environmental temperature to 15 ~ 30 ℃ is appropriate, relative humidity not more than 85%, when the environmental temperature is lower than has been in 15 ℃, heat insulation measures should be taken, when the use of raw materials, which in itself is not temperature The environmental temperature should be lower than the minimum. 2. Do not touch the resin adhesive material during construction or cured with water or water vapor. 3. backing, lining construction and surface preparation of rubber resin, the resin material shall be in strict accordance with the instructions weighed, with the distribution with the use of the full mix. Not too much time with the amount, to avoid too much heat so that premature curing rubber. 4. Non-open-air construction, construction shed must be set to prevent the gray sand, rain, dew and sunlight. 5. Never crosstalk construction, water, electricity and other factors, to prohibit access to the construction site. 6. Prohibited fireworks, watch pool body ventilation and personal protection, construction site should be well ventilated, forced ventilation must be taken when the pool closed body construction. 7. Handling of material to the construction site, be sure to place able to avoid the wind, rain and direct sunlight. And make fire safety measures.
