The climate during the construction of embossed floor has a great influence on the construction quality. Construction should avoid rain, snow, sand and freezing weather. Construction at night is prohibited in places with large temperature difference between day and night, and the construction environment temperature should generally be above 2℃. A good construction environment can ensure the construction quality of the mold floor, so it is necessary to avoid overlapping construction with other construction teams, and take closed measures for the mold floor construction site when necessary. Gravel and plain soil foundation must be compacted or tamped by roller.
The concrete strength of the relief floor base should be ≥C25, and its water-cement ratio should be as small as possible, and the concrete should not contain early strength agent.
The thickness of concrete must be consistent, and the foundation concrete must be 125px or above. The maximum particle size of crushed stone aggregate in concrete is ≤37.5px, the concrete below 250px is vibrated by flat vibrator, and the concrete above 250px is vibrated by plug-in.
After the concrete is vibrated, the platform is repeatedly rolled with heavy long steel wheels (the steel wheels should be more than 0.3m wider than the bottom die) to make the platform smooth. When rolling the platform, clean the foreign bodies on the steel roller. After the concrete is lifted, make sure that there is no sand on the surface. In the parts that cannot be operated by steel rollers, the slurry should be manually lifted and the platform elevation should be scraped out with a level.
After the concrete platform is flooded horizontally, before the initial setting of the surface, the concrete surface is leveled with artificial iron plate.
