An underground excavation engineering construction methods and underground station

The present invention discloses a method of underground construction engineering excavation and underground stations. The excavation of underground construction method comprising the top and two sides of the peripheral outer side of the pit along the underground engineering work underground engineering structures uniformly arranged plurality of longitudinal Jacking, a peripheral welded steel mesh with each other and the wing; timely Jacking excavation of the pipe and the soil adjacent steel blade within the scope of the package, and the use of steel connecting member adjacent transverse connector; closed ends of adjacent pipe ends and the steel blade the packet range, and with respect to the steel o steel blade within a poured concrete packet range, so that the steel mesh with each other and wall forming the overall force; stepwise excavation underground engineering structures main beams, columns corresponding to the portion of soil, and facilities to do after the excavation of soil beams, columns, structural body structure; and simultaneously with the excavation of the soil layers were applied to make the main structure and wall structures. This construction method can better control land subsidence, the construction process and high safety, high degree of mechanization.
