technical field

The invention belongs to the technical field of foundations of buildings or structures, and in particular relates to an assembled foundation with adjustable lateral support.

Background technique

In some cold, large temperature difference between day and night or high altitude areas, the use of cast-in-place concrete for foundation construction not only requires a lot of manpower and material resources, but also easily leads to quality defects in the foundation due to inadequate construction and maintenance. Therefore, under extreme weather conditions, the construction technology of using prefabricated foundations instead of cast-in-place concrete foundations came into being. However, prefabricated foundations have higher requirements for their integrity. There are errors and large gaps in the prefabrication process of the type foundation, which lead to different tightening degrees of the bolts during the assembly process, which makes the foundation prone to loosening and deformation after being stressed, which in turn has a great impact on the integrity of the foundation.
