Frozen station end wall and shield receiving system
The invention belongs to the technical field of shield receiving and launching, and discloses a freezable station end wall and a shield receiving system.The freezable station end wall comprises a station end wall body and a supporting side wall constructed on one side of the station end wall body, the station end wall body is provided with a tunnel portal, and an embedded steel ring is arranged on the inner side of the tunnel portal; the supporting side wall is provided with a penetrating part corresponding to the embedded steel ring, and the penetrating part is used for a shield to penetrate through. A first freezing pipeline is pre-buried in the supporting side wall, the first freezing pipeline is distributed on the outer side of the crossing part in the circumferential direction of the crossing part, the first freezing pipeline is provided with a liquid inlet end and a liquid outlet end, and the liquid inlet end and the liquid outlet end penetrate through the station end wall and extend out of the station end wall. Underground water is effectively prevented from entering the station from the outside of the station, the sealing and water stopping effects are good, construction of a primary structure is not affected, a secondary structure is not changed, and interference to a secondary permanent structure is small.
本发明属于盾构接收和始发技术领域，公开了一种可冷冻车站端墙及盾构接收系统，其中的一种可冷冻车站端墙，包括车站端墙和构筑于车站端墙一侧的支护侧墙，车站端墙具有形成有洞门，洞门内侧设有预埋钢环，所述支护侧墙具有与所述预埋钢环对应的穿越部，穿越部供盾构穿过；所述支护侧墙预埋有第一冷冻管路，第一冷冻管路沿所述穿越部的周向分布于穿越部的外侧，且第一冷冻管路具有进液端和出液端，进液端和出液端穿过所述车站端墙且延伸至车站端墙外。本发明有效阻止地下水从车站外进入车站内，密封、止水效果好，并且通过预埋施工的布置形式，既不影响一次结构的施工，也不改变二次结构，对二次永久结构的干扰小。
