Hydropower station underground power-house ventilation hole and traffic hole arranging structure suitable for TBM construction
The invention discloses a hydropower station underground power-house ventilation hole and traffic hole arranging structure suitable for TBM construction. A ventilation hole and a traffic hole are constructed by TBM one-time dismounting and mounting, a section type is round, the ventilation hole and the traffic hole are adjacently mounted, the minimum thickness of the rock between the ventilation hole and the traffic hole is not smaller than the hole excavation diameter, the tail end of the ventilation hole and the tail end of the traffic hole are located on left and right end walls of an underground power house correspondingly, a tunnel between the tail end of the ventilation hole and the tail end of the traffic hole is a construction connecting hole, the construction connecting hole is aconstruction channel of the underground power house, and a main transformer chamber and a tail gate chamber sequentially mounted with the underground power house are surrounded on the inner side of acurve formed by a ventilation hole and traffic hole direction, the two holes can be subjected to concentrated running managing at a hydropower station running period, it is ensured that at the construction period of the tunnel, TBM one-time dismounting and mounting in the same site can finish excavating of two tunnels, the hydropower station underground power-house reasonable construction period can be shortened, the tunnel construction safety is improved, and the aim of reducing the harm of engineering building to the natural environment and personal health damage can be achieved.
本发明公开了一种适用于TBM施工的水电站地下厂房通风洞和交通洞布置结构，通风洞和交通洞采用TBM一次拆装完成施工，断面型式为圆形，通风洞洞口和交通洞洞口相邻设置，通风洞洞口和交通洞洞口之间的岩体最小厚度不小于洞口开挖直径，通风洞尾端和交通洞尾端分别位于地下厂房的左右端墙处，通风洞尾端和交通洞尾端之间隧洞为施工连接洞，施工连接洞为地下厂房的施工通道，与地下厂房依次排列的主变室、尾闸室被围在通风洞和交通洞走向形成的曲线里侧。满足水电站运行期两洞能集中运行管理，确保隧洞在施工期做到TBM在同一场地一次拆装即可完成两条隧道开挖，达到缩短水电站地下厂房合理施工工期，提高隧洞施工安全性，降低工程建设对自然环境和人员健康损害的目的。
