Step One: Foundation Treatment
The foundation surface should be chiseled. There should be no debris, floating slurry, floating ash, oil stains, release agents and other debris on the surface of the clean foundation.
The foundation surface should be fully moistened one hour before grouting and the accumulated water should be removed one hour before grouting.
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 template 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, add water and stir according to the -% standard for the general reinforced type. Add water and stir according to the -% standard for the pisolite reinforced type.
It is recommended to use mechanical stirring method. The mixing time is generally - minutes (hand-operated electric drill type mixers are strictly prohibited). When using manual mixing, add / of 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.
. It is strictly prohibited to mix any additives or external additives into the grouting material when used on site.
Step 4: Grouting construction method
For longer equipment or track foundations, segmented construction should be used.
, Illustrations of several commonly used grouting methods
, Secondary grouting should meet the following requirements.
① During secondary grouting, grouting should be carried out from multiple points on one side or adjacent two sides until it overflows from the other side to facilitate exhaust during the grouting process
Grouting shall not be carried out from all four sides at the same time.
②. After the grouting starts, it must be carried out continuously without interruption. And shorten the grouting time as much as possible.
③. Vibration is strictly prohibited during the grouting process. If necessary, a grouting booster can be used to push the grouting material along the bottom of the grouting layer. It is strictly forbidden to push from the middle or upper part of the grouting layer to ensure the homogeneity of the grouting layer.
④ After the equipment foundation grouting is completed, a bevel should be cut outwards along the edge of the equipment (see the figure below) within 1 hour after grouting to prevent free ends
If cracks occur and cannot be trimmed, they should be trimmed during grouting After - an hour, use a spatula to calender the surface of the grout layer.
⑤ When the thickness of the grouting layer exceeds the thickness of the grouting layer, pisolite-reinforced high-strength non-shrinkage grouting material should be used.
⑥. When the equipment foundation grouting volume is large, mechanical stirring should be used to stir the pisolite-reinforced grouting material to ensure grouting construction.
Step 5: Maintenance
After grouting is completed, it should be immediately covered with a wet grass cover or rock wool quilt and kept moist within minutes.
Maintenance measures during winter construction should also comply with the relevant provisions of the current reinforced concrete engineering construction and acceptance specifications ().
After the grouting material reaches the film removal time, the equipment can be installed. For the specific time, please refer to the relationship table between film removal and curing time and ambient temperature.
After the equipment foundation grouting is completed, if there is any part that needs to be removed, it can be removed gently with a spatula or
shovel tool - an hour after the grouting is completed and before the grouting layer hardens.
. The vibration of the running machine must not be transmitted to the equipment foundation. After the second grouting, the machine should be stopped for an hour to avoid damaging the unhardened grouting layer
