Underground powerhouse spiral drainage gallery excavation arrangement form and excavation method
The invention discloses an underground powerhouse spiral drainage gallery excavation arrangement form and excavation method.The structure comprises a TBM tunneling tunnel section and a drilling and blasting method tunnel section, and the TBM tunneling tunnel section comprises a four-layer spiral descending drainage gallery, a top layer middle annular drainage gallery and a water diversion lower adit drainage gallery which are annularly arranged around an underground powerhouse; the drilling and blasting method hole section comprises an assembling hole section, a starting hole section and other branch holes. By adopting the mode of combining the TBM and the drilling and blasting method, excavation of the drainage gallery of the underground powerhouse has the advantages that the construction mechanization and intelligence level is achieved, the safety risk of underground engineering construction is reduced, and the engineering quality and the intrinsic safety level are improved.
本发明公开了一种地下厂房螺旋式排水廊道开挖布置形式及开挖方法，所述结构包括TBM掘进洞段和钻爆法洞段，所述的TBM掘进洞段包括地下厂房周围环形布置的四层螺旋下降排水廊道、顶层中间环形排水廊道以及引水下平洞排水廊道，所述钻爆法洞段包括组装洞段、始发洞段及其余支洞。通过采用TBM及钻爆法相结合的方式，使得地下厂房排水廊道的开挖具有施工机械化、智能化水平，降低地下工程施工安全风险，提升工程质量和本质安全水平等优点。
