Background

With the rapid development of economy, the subway construction in China is in a high-speed development period. In busy areas of cities, traffic key roads and densely populated areas, more and more subway stations are constructed by adopting a subsurface excavation method in order to not damage the existing traffic conditions and not influence the daily life of residents around projects. In the construction of the underground excavation method, the construction of the subway tunnel by the construction of the construction channel is changed into a trend. However, due to the complexity of the excavation construction process of the tunnel at the transition section, the construction process of the transition section between the construction channel and the station tunnel is more, the stress conversion of the structural system is frequent, and the deformation, stress and stress conditions of the surrounding rock and the stress of the supporting structure are complex in the process that the construction channel enters the main tunnel. In addition, because the section of the construction channel is small and the section of the station tunnel is large, the construction of the conversion section often needs more steps, which becomes a key for restricting the construction period of the tunnel.

At present, a plurality of mature construction methods for entering a large-section station through a small-section construction channel are available, such as a large-package method, a CRD method and the like. Aiming at the characteristics of high construction difficulty and complex process of the urban subway transverse passage to main tunnel, a large-package process conversion method is mostly adopted. The construction is carried out according to the principles of short footage, strong support, early sealing and sinking control by combining the actual situation of the site and the geological characteristics. Aiming at special geological sections such as weak surrounding rocks, soil layers and the like, the top-picking process method is reasonable and effective. The construction of the top-picking construction method can ensure the stability of the tunnel surrounding rock and ensure the safety of construction and normal construction period.

However, the existing roof picking procedure method is simple in a door-shaped roof picking structure, and the roof picking structure cannot be correspondingly adjusted according to actual installation requirements, so that the installation efficiency of the roof picking structure is influenced.
