How to use the special line for passenger transport bridge pot rubber bearing grouting material

Bearing grouting support grouting material construction bearing grouting material how to 1. To need cut wool processing base of grouting, eliminating the dust, grease and other dirt adhesive material; To repair the defects such as cracks; Install the grouting template; Bearing pad stone surface wet water to saturation, but not leave MingShui construction. 2. Install QPZ pot rubber bearing, steel wedge wedging bearing corners, leveling bearing, and adjust the support to the design elevation, between the bearing base and bearing pad stone reserve, 20 ~ 30 mm gap for grouting. 3. According to the construction area and construction area computation powder feed rate per unit time and water consumption, and each mixing amount should guarantee the loss of flow in the mortar construction completely before sex. 4. Pulp press powder: water = 1-0. 14 - 0. 15 ( Weight ratio) Preparation. Should be first to add water to mixing barrel, then gradually add weighing good grouting material, feeding while gun with electric mixer for mixing, until the powder is added, and continue to stir 3 ~ 4 minutes, make the paste evenly. 5. Pour after mixing slurry is uniformly in dealing with good base surface, self-leveling. Using gravity grouting filling pedestal and anchor bolt hole at the bottom of the gap. To grouting, grouting process from support center until around from the template and bearing plate gap observed in the complete filling grouting materials. 6. Flow should be completed within the construction time, construction machines and after rinse with water immediately. 7. Grouting material after the final set, dismantling formwork and steel wedge, check whether there is a leak slurry, to fill slurry, slurry leakage in the gap and take out after filling wall steel wedge, tighten the anchor bolt support plate. 8. For placing concrete beam body, dismantled upper and lower bearing connecting plate, and installing bearing steel plate. 9. Depending on the ambient temperature, construction time at 20 ℃ for mixing within 30 minutes after completion. 10. Material consumption of 2100 ~ 2200 kg/m3
