The invention discloses a tunnel reserved interface structure which comprises a connecting section extending out of a blocking wall, a protective sleeve is arranged outside the connecting section in a sleeving mode, a waterproof edge extends on a wall body on the upper portion of the connecting section, and a supporting plate extends on a wall body on the lower portion of the connecting section and is consistent with the extending direction of the connecting section. A gap is reserved between the waterproof edge and the connecting section, a gap is reserved between the supporting plate and the connecting section, and the protective sleeve is just inserted into the gaps. The gap structure is firstly poured and formed, then the protective sleeve is additionally arranged in the later period, the side wall of the firstly-poured gap structure is isolated from the underground environment, physical isolation is formed, the protective sleeve is convenient to install, the connecting position of the protective sleeve and the firstly-poured structure is protected, support is provided below the supporting plate protective sleeve, and pressure outside the protective sleeve is reduced; the connection strength between the pre-cast structure and the protective sleeve is improved, and the physical and water stop steel plate double-layer waterproof effect is formed at the post-cast strip position.
本发明公开了一种隧道预留接口结构，包括延伸至封堵墙外的衔接段，所述衔接段外套设有保护套，在所述衔接段上部的墙体上延伸防水缘，在所述衔接段下部的墙体上延伸与所述衔接段延伸方向一致的支撑板件，所述防水边缘和衔接段之间、所述支撑板件和所述衔接段之间留有间隙，所述保护套正好插入所述间隙中。间隙结构先浇筑成型，后期再加装保护套，先浇筑的间隙结构侧壁隔离地下环境，形成物理隔离，便于保护套安装，有助于保护保护套与先浇结构的连接处，支撑板件保护套下方提供支撑，减小保护套外的压力，增加先浇筑结构和保护套之间的连接强度，后浇带位置形成物理和止水钢板双层防水效果。
