Small-section large-corner shallow-buried excavation electric power tunnel mechanical construction method
The invention belongs to the technical field of electric power construction, and particularly relates to a mechanical construction method for a small-section large-corner shallow-buried excavation electric power tunnel. The method comprises the following steps: performing tunnel face drilling grouting reinforcement construction; non-blasting mechanical excavation is conducted on the whole section of the electric power tunnel through a rotary excavation arm; the excavated area is subjected to advanced small pipe supporting and sprayed concrete plugging; mounting a grid arch frame; concrete is sprayed to the installed grating arch frame, and an electric power tunnel primary support is formed; and central core soil in the power tunnel is excavated. By means of the scheme, rapid excavation, deslagging, advance supporting, arch erecting and spraying and mixing primary supporting can be achieved, and construction procedures and construction steps can be reduced.
本发明属于电力施工技术领域，具体涉及一种小断面大转角浅埋暗挖电力隧道机械化施工方法。本发明方法包括：进行掌子面钻孔注浆加固施工；采用回转式挖掘臂对电力隧道全断面进行非爆破机械开挖；对于挖掘后的区域进行超前小导管支护以及进行喷射混凝土封堵；安装格栅拱架；对安装好的格栅拱架喷射混凝土，形成电力隧道初支；对电力隧道中的中心核心土进行挖掘。通过本方案可快速开挖、出渣、超前支护、立拱架、喷混初支，并且可减少施工工序、施工步骤。
