Long-distance outgoing line hole structure of underground powerhouse
The invention discloses a long-distance outgoing line hole structure of an underground powerhouse. The long-distance outgoing line hole structure comprises an outgoing line inlet section and an outgoing line outlet section, the upper layer is connected with the tail end of the outgoing line inlet section, the lower layer is used for constructing a ventilation patrol channel, and one end, close to the outgoing line inlet section, of the ventilation patrol channel is connected with a middle-layer drainage gallery so as to be connected with an incoming traffic tunnel; the tail end of the outgoing line outlet section is connected to a cable interlayer of a ground switching station, and the inspection tour outlet section is directly communicated with the ground; the outgoing line inlet section, the upper layer of the composite tunnel section and the outgoing line outlet section are all provided with fire retardant devices which are arranged along an outgoing line way at intervals, so that a plurality of fireproof subareas are divided; and corresponding to each fireproof subarea on the upper layer of the composite tunnel section, the laminate between the upper layer and the lower layer is correspondingly provided with a maintenance manhole and is provided with a fireproof cover plate. Long-distance traveling maintenance and inspection of the outgoing adit of the underground powerhouse are achieved, the construction period of the ground switching station is shortened, and meanwhile the natural ventilation function and the fire-fighting escape function are achieved.
本发明公开了地下厂房长距离出线洞结构，包括：连接地下主变洞的出线进口段；和具有上下两层的复合洞段，其中上层连接出线进口段末端，下层用以构造通风巡视道，其靠近出线进口段的一端连接中层排水廊道，从而连接进厂交通洞；及分别连接复合洞段上下层末端的出线出口段和巡视出口段，前者末端接入地面开关站电缆夹层，后者直通地面；出线进口段、复合洞段上层及出线出口段均设置阻火装置，并沿出线道间距布置，从而分隔成多个防火分区；对应于复合洞段上层每一防火分区，上下层之间的层板相应地开有检修进人孔，并配有防火盖板。本发明实现地下厂房出线平洞长距离行车检修、巡视以及缩短地面开关站建设周期，同时兼具自然通风及消防逃生功能。
