Secondary grouting construction for equipment installation
Step 1: Foundation treatment
The surface of the foundation should be roughened. 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 1 hour before grouting and any accumulated water should be removed 1 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 are 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.
. 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.
. After the grouting starts, it must be carried out continuously without interruption. And shorten the grouting time as much as possible.
. 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.
. After the equipment foundation grouting is completed, a bevel should be cut outwards along the edge of the equipment (see the figure below) - hours after grouting to prevent cracks at the end. If the edge cannot be trimmed, it should be cut - hours after grouting. Use a spatula to smooth the surface of the grout layer.
. When the thickness of the grouting layer exceeds , pisolite-reinforced high-strength non-shrinkage grouting material should be used.
. 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 regulations of the current ().
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.
If there is any part that needs to be removed after the foundation grouting of the equipment is completed, it can be gently removed with a spatula or shovel tool one 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 1 hour to avoid damaging the unhardened grouting layer.
