Pre-buried steel plate connecting structure for underground continuous wall and foundation base plate
The invention belongs to a pre-buried steel plate connecting structure for an underground continuous wall and a foundation base plate in the field of foundation pit supporting and foundation engineering. The technical scheme is that a vertical early pre-buried steel plate is pre-buried on the outer side of a reinforcement cage in the underground continuous wall; the center elevation of the early pre-buried steel plate is the same as the elevation of the main reinforcement of the foundation base plate; and a post welded steel plate which is constructed after a foundation pit is excavated to thebottom of the pit is vertically welded to the early pre-buried steel plate, and is welded and fixed after being lapped with the main reinforcement of the foundation base plate transversely. Accordingto the structure, the technical problem that the position precision of a reserved steel bar connector in a conventional connecting method adopted by the underground continuous wall is difficult to ensure and then the reliable connection is difficult to provide is solved; and meanwhile, the stress requirement for the connection between underground continuous wall and the foundation base plate is met.
本发明属于基坑支护领域及基础工程领域的地下连续墙与基础底板的预埋钢板连接构造，技术方案为地下连续墙内的钢筋笼的外侧预埋竖向的先期预埋钢板；先期预埋钢板的中心标高与基础底板主筋标高相同，基坑开挖到坑底之后施工的后焊接钢板垂直焊接所述先期预埋钢板，并与基础底板主筋横向搭接后焊接固定。该构造解决了地下连续墙采用常规连接方法中的预留钢筋接驳器位置精度难以得到保证，进而难以提供可靠连接的技术问题，同时满足了地下连续墙与基础底板连接的受力要求。
