1, after the ground beam construction is completed, it will take about 10-20 days to backfill, and the specific time will be determined according to the ground beam maintenance strength; Because the strength of concrete can reach about 80%-90% at this time. When using mechanical compaction, it is necessary to level the soil first, and the bulldozer is slowly rolling it back and forth; The speed of mechanical rolling should not be too fast, so as not to cause land collapse; Mechanical rolling should keep a certain distance from the pipeline.
2. Ground beam, also known as geosphere beam, can play a negative role in slowing down uneven settlement and enhancing the integrity of the house. After the ground beam is poured, it usually needs water conservation, which can make the ground beam have a suitable hardening condition and is more conducive to maintaining its strength; The ground beam is not well maintained in the later period, and the concrete is easy to crack or fall off.
3. Whether it is necessary to make a ground beam when building a house depends on the local seismic fortification and foundation. If the local seismic fortification is below 6 degrees, the building foundation is good and the building budget is insufficient, you can consider not making ground beams; If the construction budget is sufficient, you can consider building ground beams.
Some people will consider strengthening the ground beam when building a house. You can cut the side of the ground beam, and the stirrup should be exposed at the top of the ground beam. After the side of the ground beam is cleaned, brush the anti-seepage treasure, punch holes, and install rebar and reinforcement; After welding, concrete can be poured.
Let me sum up: I will briefly introduce the fact that the ground beam can press the car in a few days. I hope that after reading this article, everyone can understand this. Everyone should lay a good foundation and ground beam when building a house.
