Description

Technical Field

[0001] The invention relates to the field of architectural design, in particular to an elastic connection structure connecting a basement to an underground passage. Background Art

[0002] Due to functional requirements, it is often necessary to create a connecting passage underground between two buildings, connecting them via an underground corridor to facilitate transportation and use. This requires creating an opening in the existing structure's underground exterior wall and connecting the subsequent building via an underground corridor. The underground connection significantly alters both waterproofing and the stresses of the original structure, complicating the structural system and making construction difficult.

[0003] The commonly used connection method at present is to use rigid connection at the connecting channel (that is, planting reinforcement and then pouring concrete at the intersection structure). This connection limits the settlement and deformation of the new and old structures. Usually, due to the asynchronous settlement and deformation of the new and old structures, cracks and leakage occur at the connection position. In severe cases, it may affect the structural stress, cause structural cracks, and affect safety of use. Summary of the Invention
