[0021] As Figures 1 to 8As shown in the figure, a precast concrete box substation foundation includes a base 1, a ring beam 2 and a coping 3. The base is formed by splicing and enclosing several base splicing beams 5. The ring beam is formed by splicing and enclosing several intermediate splicing beams 6. The coping is formed by splicing and enclosing several coping splicing beams 7. There are several upper columns 8 connected between the ring beam and the coping, and several lower columns 9 connected between the ring beam and the base. Side baffles 4 are installed in the rectangular areas formed by two adjacent upper columns, the ring beam and the coping, and in the rectangular areas formed by two adjacent lower columns, the ring beam and the base. This precast concrete box substation foundation adopts a modular design.
