, grouting booster. , Templates (steel molds, wooden molds).
, straw bags, rock wool quilts, etc. , cotton yarn, tape.
Grouting construction
The first step: foundation treatment
The surface of the foundation should be roughened, or a special reinforcing interface agent concrete re-pouring agent should be used for interface treatment.
Clean the foundation surface, and there should be no debris, floating slurry, floating ash, oil stains, release agents and other debris.
Before grouting, the foundation surface should be fully moistened, and accumulated water should be removed before grouting.
Step 2: Set up the formwork
Set up the formwork 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 (quick leak-stopping agent is recommended), 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, add water and stir according to the standard of 3- for the general reinforced type, and add water and stir according to the standard for the pisolite reinforced type.
It is recommended to use mechanical mixing method, the mixing time is generally - (hand electric drill type mixer is strictly prohibited). When using manual mixing, you should first add /3 of the water to mix, then add the remaining water and mix until uniform.
The amount of mixing each time should be determined according to the usage amount to ensure that the material is used up within the time limit.
When used on site, it is strictly prohibited to mix any additives or external additives into the grouting material.
Step 4: Grouting construction method
For long equipment or track foundation, segmented construction should be used.
Illustrations of several commonly used grouting methods:
During secondary grouting, the following requirements should be met.
When grouting for the second time, 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 grouting begins, 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, the grouting booster can be used to push the grouting material along the bottom of the grouting layer. It is strictly prohibited 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, the bevel should be cut outward along the edge of the equipment 3-3 months after grouting to prevent cracks at the free end. If the edge cannot be trimmed, it should be trimmed with a spatula 3-3 months after grouting. The surface of the grouting layer is calendered.
When the thickness of the grouting layer exceeds 100%, 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 wet straw curtains or rock wool quilts and kept moist within 3 days.
During winter construction, maintenance measures should also comply with the relevant provisions of the current reinforced concrete engineering construction and acceptance specifications (B).
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 gently removed with a spatula or shovel tool 3-3 days after the grouting is completed, that is, before the grouting layer hardens.
. The vibration of the running machine must not be transmitted to the equipment foundation. After the secondary grouting, the machine should be stopped to avoid damaging the unhardened grouting layer.
