Tunnel portal structure of shield interval
The invention relates to the technical field of subway civil construction, and discloses a tunnel portal structure of a shield interval. The tunnel portal structure comprises a wall body, a door frame, an arch wall and a flood gate, wherein the wall body is provided with a hole channel used for communicating with the shield interval; a door hole is formed in the top wall of the hole channel; the door frame is arranged in the hole channel; a U-shaped groove which is provided with an upward opening and communicates with the door hole is formed in the door frame; the outer wall of the door frameis attached to the inner wall of the hole channel; sliding grooves are formed in the two side walls of the U-shaped groove and extend in the vertical direction; one end of the arch wall is attached tothe wall body; the flood gate is arranged in the door hole in a penetrating mode and extends into the U-shaped groove; and one side of the flood gate is slidably arranged in the first sliding groove,and the other side of the flood gate is slidably arranged in the second sliding groove. The flood gate is slidably connected to the door frame, when a large amount of flood flows in, the flood gate can seal the hole channel, the blocking effect is formed, and the flood is prevented from submerging the hole channel.
本发明涉及地铁土建施工技术领域，公开了一种盾构区间的洞门结构，包括：墙体、门框、拱墙以及防淹门。墙体开设有用于与盾构区间连通的孔道；所述孔道的顶壁上开设有门孔。门框设于所述孔道内，所述门框上开设有开口朝上并与所述门孔连通的U型槽；且所述门框的外壁贴合在所述孔道的内壁上；所述U型槽的两个侧壁上开设有滑槽，滑槽沿竖直方向上延伸。拱墙的一端贴合在所述墙体上。防淹门穿设在所述门孔并伸入所述U型槽内；所述防淹门的一侧滑设在所述第一滑槽内，所述防淹门的另一侧滑设在所述第二滑槽内。本发明设置的门框上滑动连接有防淹门，当有大量洪水涌入时，防淹门能够封闭孔道，形成阻隔作用，防止洪水淹没孔道。
