Background Art

[0002] There are many kinds of foundations for traditional house construction, and these foundations require excavation, template making, and concrete pouring during construction. This traditional construction method not only consumes a lot of manpower and financial resources, but also has a relatively long construction period.

A foundation used for rapid construction of soft soil and sandy soil solves the above problems very well. This foundation not only saves the steps of earth excavation, template making, and concrete pouring, but also has the advantages of simple operation, safer and more environmentally friendly construction, and provides new ideas for the construction of lightweight houses and small bridge foundations.
