The first step: foundation treatment
The surface of the foundation should be roughened. Clean the foundation surface, and there should be no gravel, floating slurry, floating dust, oil stains, release agents and other debris.
One hour before grouting, the foundation surface should be fully moistened, and one hour before grouting, any accumulated water should be removed.
Step 2: Support and touch
Set up the template according to the grouting construction drawing. The joints between the formwork and the foundation and between the formwork and the formwork should be sealed with cement slurry, tape, etc. to ensure that the entire formwork does not leak.
The horizontal distance between the formwork and the equipment base should be controlled to the left and right to facilitate grouting construction.
The top elevation of the formwork should be higher than the upper surface of the equipment base.
If grouting occurs during grouting, it should be dealt with in time.
Step 3: Preparation of grouting material
Generally speaking, add water and stir according to the standard of 3- for the general reinforced type, and add water and stir according to the standard of - for the pisolite reinforced type.
It is recommended to use mechanical stirring method, and the stirring time is generally - minutes (hand-operated electric drill type stirrers are strictly prohibited). When using manual mixing, you should first add /3 of the water and mix for 1 minute, then add the remaining water and mix until uniform.
The amount of stirring each time should be determined according to the amount of use to ensure that the material is used up within minutes.
When used on site, it is strictly prohibited to mix any additives or external additives into the grouting material.
