Grouting construction
Step 1: Basic Processing
The base surface should be roughened. Clean the base surface, ensuring there is no debris, slurry, loose dust, oil stains, or release agents. Prior to grouting.24 hours, the base surface should be fully moistened. One hour before grouting, remove any standing water.
Two-step: Feel
1. Set up forms according to the grouting construction drawing. Seal the joints between the forms and the foundation, as well as between forms, using cement grout and tape to ensure the entire form set is watertight.
2. The horizontal distance around the template and base should be maintained at about 100mm to facilitate grouting work.
3. The template's top elevation should be 50mm above the surface of the equipment base.
4. If leakage occurs during grouting, it should be addressed promptly.
Step 3: Grout Material Preparation
Generally, water is mixed in accordance with a standard of 13-14% for general reinforced type, and 9-10% for stone aggregate reinforced type.
2. Use mechanical stirring, which typically takes 1-2 minutes (do not use a drill-type stirrer). When stirring manually, first mix for 2 minutes with 2/3 of the water, then add the remaining water and stir until uniform.
3. The mixing quantity should be determined based on the usage amount to ensure the material is used up within 40 minutes.
4. During on-site use, it is strictly prohibited to mix any admixtures or external additives into CGM grouting material.
Step 4: Grouting Construction Method
1. For longer equipment or track foundations, segmented construction should be employed.
2. Diagrams of several commonly used grouting methods
3. During secondary grouting, the following requirements should be met.
1.1 During the secondary grouting, the grouting should be performed from multiple points on one side or adjacent sides until it overflows from the opposite side, to facilitate air release during the grouting process. Grouting from all four sides simultaneously is not allowed.
1.2 Once grouting begins, it must be carried out continuously without interruption, and efforts should be made to minimize the grouting time.
During grouting, vibration is strictly prohibited. If necessary, the CGM grouting material can be propelled along the bottom of the grouting layer using a grouting propeller; it is strictly forbidden to push from the middle or upper part of the grouting layer to ensure the homogeneity of the grouting layer.
1.4 After the equipment foundation grouting is completed, a 45-degree bevel should be cut along the equipment edge within 3-6 hours post-grouting (as shown in the figure below) to prevent cracks from forming at the ends. If edge cutting is not possible, the grouting layer surface should be smoothed with a trowel within 3-6 hours after grouting.
When the thickness of the grouting layer exceeds 150mm, use reinforced aggregate high-strength shrinkage-free grouting material.
1.6 When the base grouting volume of the equipment is large, mechanical mixing should be used for the aggregate reinforced grouting material to ensure the grouting construction.
Step 5: Maintenance
Within 30 minutes after grouting is complete, immediately cover with wet straw or mineral wool blankets and maintain moisture.
2. During winter construction, maintenance measures should also comply with the relevant provisions of the current (GB50204).
3. After the grouting material reaches the time for peeling off the film, installation of the equipment can be carried out. Refer to the "Table of Relationship Between Film Peeling and Curing Time and Environmental Temperature" for the specific time.
4. After the equipment foundation grouting is completed, if any parts need to be removed, they can be gently scraped off with a trowel or shovel tool 3-6 hours after grouting, before the grout hardens.
5. Do not transmit vibration from operating machinery to the equipment foundation. After secondary grouting, the machine should be shut down for 24-36 hours to prevent damage to the unhardened grouting layer.
