模板要正确密封，能防止灌浆料的泄漏。伸缩缝准备伸缩缝能有效减少裂缝的产

The template should be properly sealed to prevent the leakage of grout. <br>Expansion joint preparation <br>Expansion joint can effectively reduce the occurrence of cracks. When the area of ​​grouting exceeds 1.8m×1.8m, an expansion joint with a thickness of less than 20mm can be set. The material is elastic foam plastic strip and the foam plastic strip is fixed with silicone On the base surface and the inside of the template, perpendicular to the centerline of the bottom plate. <br>After grouting, the exposed part is removed, and then the surface of the expansion joint is sealed with silicone. <br>The bottom plate is prepared to <br>check that all the bottom corners of the bottom plate have a radius of at least 50 mm (2 inches) to prevent cracks in the foundation grouting due to stress concentration at the corner; ensure that all anchor bolt holes have a ring clearance of at least 3 mm to allow the bottom plate to be Replacement; <br>check that all pumps and other small bottom plates have vertical adjustment <br>jacks ; check that the bottom plate has a 10 cm (minimum) grouting hole in each compartment, and a 12 mm row near each corner of the section Air holes; ensure that each compartment has sufficient grouting holes and exhaust holes; ensure that the bottom plate adjustment top wire has carbon steel leveling pads; ensure that the welds of all bottom plates are continuous and free of cracks. <br>Remove all grease and dirt on the grout surface of the bottom plate. <br>The bottom plate adjustment top wire should be coated with enough wax or grease; other bottom plate holes (such as the holes of the coupling cover) should be blocked to prevent the entry of grout. <br>Ensure that all equipment is isolated and disconnected from all pipelines, pipes, etc., and the equipment is in a stress-free state. <br>After the contact surface of the bottom plate with acid-resistant epoxy grouting has been blasted, if the interval between blasting and grouting is longer, use a primer corresponding to the grout at the bottom of the bottom plate. <br>If the pump bottom plate has an embedded structure, sandblasting can be omitted. <br>Pre-grouting meeting <br>At least one day before grouting, convene a pre-grouting meeting attended by all grouting staff to understand and agree on the procedures to be taken to ensure all required materials and clarify everyone's grouting responsibilities. <br>Preparation before grouting<br>Before grouting, the grouting material should be stored at an ambient temperature of 16° to 32° for more than 24 hours to ensure that the material has the best performance during use.
