Abstract

The invention discloses an assembled electrochemical energy storage prefabricated cabin foundation, and belongs to the technical field of energy storage facility construction. The prefabricated steel frame comprises a foundation steel beam and a connecting steel sleeve, wherein the foundation steel beam is connected with the connecting steel sleeve, the connecting steel sleeve is sleeved on the pile top of the reinforced concrete prefabricated pile in an adjustable mode along the axial direction, and a pouring space is formed between the connecting steel sleeve and the reinforced concrete prefabricated pile. The assembled electrochemical energy storage prefabricated cabin foundation structure disclosed by the invention mainly comprises prefabricated components, so that the construction process is simplified, and the engineering construction time is shortened. By adopting the steel sleeve and the post grouting connection mode, pile foundation construction errors in a certain range can be tolerated, and even if the pile foundation position deviates or the pile top elevation does not reach the design elevation, the pile foundation construction errors can be regulated by adjusting the elevation position of the connection steel sleeve, the follow-up installation is not influenced, and the construction flexibility and fault tolerance are greatly improved.
