Taian grout | Qi are brand impregnable one, use a grout material. Basic cleaning equipment based on surface treatment, without gravel, laitance, dust, oil and other debris. Grout before 24h, basic equipment should be fully wet the surface. Before filling 1h, should suck water. 2. Filling way to determine the actual status of the device cradle choose grout way, by having good flow properties, usually with "Filling weight method" can be, since the template is about to direct the slurry poured into the mouth, totally dependent on the weight of its own slurry flow flat and fill the entire space perfusion; if perfusion area of ??the large, complex structure or a very small space and distance, we can use "high funnel method grout" or "pressure grouting method" grouting to ensure that the slurry can be fully filled every corner . 3. Formwork grout according to the determined way and grouting Figure branch set template, locate the device level should be higher than the base surface of at least 50mm, the template must support set tight, secure, prevent loosening, leakage of plasma. 4. Stirring grout material product certification by the water than on determining the amount of water, the water temperature to 5 ~ 40 ℃ is appropriate, can be mechanical or manual mixing. When using mechanical stirring, the stirring time is generally 1 to 2 minutes. Artificial stirring advised adding 2/3 water for 2 minutes, after adding the remaining water and continue stirring until uniform consistency add water standard of 12% -14%. 5. Construction should grout filling the following requirements: (1) the slurry should be poured into the side until the other side of the overflows in order to facilitate the discharge of air equipment between the base and the concrete foundation, so filling enriched, shall from four sides Meanwhile grouting. (2) filling the beginning, must be continuous, without interruption, and (3) in the grouting process should not be vibrated, if necessary, can be pulled bamboo strips diversion. (11) filling in as plasma phenomena appear to run, should be promptly treated. (12) When the equipment is large foundation grouting, mechanical mixing method should be used to ensure the grouting. 6, grout curing (1) filling is completed within 30 minutes, immediately curing agents sprayed or covered with plastic film and stamped with rockwool and other conservation or immediately after the final setting of the grout layer watering moisture conservation. (2) When the winter construction, conservation measures should also comply with the current "reinforced concrete construction Acceptance" (GB50204) the relevant provisions. Updated: November 3, 2014
