Shandong grout | Qi all brands, bolstered by one, use a grout. Cleaning equipment based on the basis of surface treatment, without gravel, laitance, dust, oil and other debris. Grouting before 24h, basic equipment should be fully wet the surface. Before filling 1h, should suck water. 2. Filling way to determine the actual situation of equipment base, filling mode selection, due to having good flow properties, usually with "filling weight method" can be, since the template is about to paste directly poured into the mouth, totally dependent on the weight of the slurry stream itself level and fill the entire space perfusion; if perfusion area of ??great, complex structure or a very small space and distance, we can use "high filling funnel method" 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 base level should be higher on the device surface at least 50mm, the template must support set tight, secure, prevent loosening, leakage of plasma. 4. Stir 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, stirring time is generally 1 to 2 minutes. Artificial agitation, advised adding 2/3 of water for 2 minutes, then add the remaining water and continue stirring until evenly, add water standard consistency of 12% -14%. 5. Construction grout grout should meet the following requirements: (1) the slurry should be poured into the side, until the other side of the spill so far, in order to facilitate the discharge of air equipment between base and concrete foundation, so filling full, not from the four sides while grouting. (2) filling the beginning, must be continuous, without interruption, (3) during the grouting process should not be vibrated, if necessary, can be used bamboo strips were pulled diversion. (11) In case of filling in the running plasma phenomena, should be promptly treated. (12) When the equipment foundation grouting is large, mechanical mixing method should be used to ensure the grouting. 6, grout curing (1) filling is completed within 30 minutes, immediately curing compound or covered by plastic film and stamped with rockwool and other conservation or immediately after the final setting grout layer watering moisture conservation. (2) When the winter construction, conservation measures should be consistent with existing "reinforced concrete construction acceptance norms" (GB50204) the relevant provisions.
