Therefore, there is an urgent need for a modular and quickly assembled bridge foundation structure. By prefabricating the bridge foundation in the factory and then assembling it at the construction site, the curing time after in-situ casting of the bridge foundation is effectively saved, and the overall construction progress of the bridge can be effectively improved.

[0027] As a further optimized solution, a first groove 11 is opened on the top surface of the base 1, and a plurality of first limiting holes 12 are opened on the outer wall of the base 1.
