The foundation pre-embedded component 203 is on the prefabricated splicing concrete block 202. An upper steel support 1 is also installed on the upper side of the prefabricated splicing foundation 2. The size of the prefabricated splicing foundation 2 can be flexibly adjusted according to the actual installation size of the upper steel support 1 to ensure the reliable installation of the upper steel support 1 on the prefabricated splicing foundation 2 in the loess terrace. The pre-embedded steel pipe 201 is mainly used to realize the installation of the upper steel support 1 on the prefabricated splicing foundation 2, thereby realizing the full utilization of land resources in the loess terrace.
