CGM high-strength non-shrinkage grouting material preparation work before construction

grouting material construction preparation, cement-based high-strength non-shrinkage grouting material construction technology of foundation reinforcement technology and the steps are as follows: 1. Foundation treatment cleaning equipment foundation surface, can not have at any time, bleeding, dust, oil and demoulding seam an agent and other sundry. 24 hours before grouting, equipment foundation surface should be fully wet. 1 hour before grouting, should suck up water. 2. Determine grouting method according to the actual situation of equipment base, choose corresponding grouting method, because the cement base high-strength non-shrink grout material has good liquidity, in general, use 'gravity method grouting'; If the perfusion volume and complex structure of special cargo space is small and the distance is far, funnel hair grouting can adopt 'high' or 'method of pressure grouting for grouting and can ensure the grouting material composition filled every corner. 3. Mode branch according to determine the direct way of grouting and grouting construction template, the template at the top of the coordinates, high equipment foundation base should be high on the surface at least 50 mm, direct template must be strict, solid, one side is loose, slurry leakage.
