Underground powerhouse drainage gallery and artesian drainage tunnel arrangement structure and excavation method
The invention provides an underground powerhouse drainage gallery and artesian drainage tunnel arrangement structure which comprises an artesian drainage tunnel, an underground powerhouse drainage gallery and a diversion lower adit drainage gallery. The underground powerhouse drainage gallery is annularly provided with a first tunneling tunnel section constructed through a TBM around an underground powerhouse; three layers of spiral corridor parts which rise spirally are arranged in the first tunneling tunnel section, the spiral corridor part on the top layer is communicated with the water diversion lower adit drainage corridor through TBM excavation, a middle annular corridor part which is tunneled through the TBM is arranged on the spiral corridor part on the top layer, and the spiral corridor part on the bottom layer is communicated with the gravity drainage tunnel. According to the method, the mode that the TBM spirally excavates the drainage gallery and the artesian drainage tunnel of the underground powerhouse is adopted, so that TBM equipment can be assembled through an assembling site outside the artesian drainage tunnel, and the first tunneling tunnel section is excavated and tunneled from bottom to top on the basis of excavation of the artesian drainage tunnel; therefore, the overall required excavation or drilling and blasting construction is more convenient.
本发明提供了地下厂房排水廊道和自流排水洞布置结构，包括自流排水洞、地下厂房排水廊道和引水下平洞排水廊道，所述地下厂房排水廊道在地下厂房周围环形布置有通过TBM施工的第一掘进洞段，所述第一掘进洞段内设有三层螺旋上升的螺旋廊道部，顶层所述螺旋廊道部与引水下平洞排水廊道通过TBM开挖连通，顶层螺旋廊道部上设置通过TBM掘进的中间环形廊道部，底层螺旋廊道部与自流排水洞连通。本发明通过采用TBM螺旋式开挖地下厂房排水廊道及自流排水洞的方式，TBM设备可因此通过自流排水洞洞外的组装场地进行组装，从而在开挖自流排水洞的基础上对第一掘进洞段进行由下而上的开挖掘进，以使整体所需的开挖或钻爆施工更为便捷。
