Description

Permanent-face combined assembled underground structure slab wall connection node Technical Field The utility model belongs to the technical field of assembled underground structures, and particularly relates to a permanent-face combined assembled underground structure slab wall connection node. Background At present, the construction technology of the assembled underground structure is gradually developed, and the assembled underground structure has the advantages of saving construction period, improving production efficiency, easily controlling construction quality, being little influenced by climatic factors and the like, and can greatly reduce construction waste generated in the construction process. However, the existing construction technology of assembled underground structures is still in a test research stage, wherein most of connection nodes still cannot achieve rigid connection similar to a cast-in-situ reinforced concrete structure, for example, china patent CN110042863A discloses a fully-composite assembled underground wall of a subway station, a prefabricated middle plate node and a construction method, the plate wall node is connected by a clamping groove, china patent CN218027825U discloses a device for connecting a side wall of the assembled subway station with the underground wall, the underground wall is connected with a side wall of the structure by an anchor bolt, and China patent CN116641725A discloses a prefabricated assembled underground station lining structure joint which achieves lining connection in a mortise-tenon mode. In a few cases of realizing the rigid connection of the plate wall of the underground structure, an outer side enclosure structure is still required to be arranged, for example, chinese patent CN113152690A discloses a connecting node of a side wall and a middle plate of an assembled structure and a construction method thereof. The patent fails to integrate the side wall of the permanent structure with the temporary enclosure structure, meanwhile, the steel consumption of the structure is large, the installation of components is complex, and the adoption of the permanently combined underground structure can greatly reduce the waste engineering quantity of the temporary structure, save the cost and avoid repeated engineering construction and material waste. Therefore, in order to better solve the problem of rigid connection of the assembled underground structure slab wall, and fully utilize the effect of the underground continuous wall in the permanent use stage, the rigid connection node of the assembled underground continuous wall and the slab has great popularization value.
