Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0029] Such as Figure 1-4 As shown, a large-span composite structure underground station includes a top floor, a side wall and a floor, and the top floor, the top floor and two side walls are arranged in the shape of a "mouth".

[0030] The top layer includes a top plate, a first stay cable, a second stay cable and a connecting rod, and a row of fixed points extending along the driving direction of the station is arranged on both sides of the middle of the top plate, and each fixed point in the row of fixed points In one-to-one correspondence with the fixing points of the other row...

Abstract

The invention relates to the technical field of rail transit or underground stations, and particularly relates to a large-span composite structure type underground station. A row of fixing points extending in the station traveling direction are arranged in the two side areas of the middle of a top plate correspondingly, wherein one fixing point of the lower side face of the top plate is fixed to one end of a first inhaul cable, and the other end of the first inhaul cable is fixed to the fixing point corresponding to the fixing point; a connecting rod is arranged between the lower side face ofthe top plate and the first inhaul cable, one end of the connecting rod is fixed to the lower side face of the top plate, and the other end of the connecting rod is fixed to the inhaul cable; and thefixing point of the upper side face of the top plate is fixedly connected with one end of a second inhaul cable, the other end of the second inhaul cable is fixedly connected with an extending section, the first inhaul cable reduces the tension and deflection of the lower surface of the center of the top plate, the second inhaul cable reduces the tension stress of the upper surface near the end ofthe top plate, safe construction of the working procedures of earth excavation below the top plate, bottom plate pouring and the like is guaranteed, the construction speed is increased, pedestrian passing is not hindered, and the time and cost for constructing a middle structure column are saved.

Description

technical field [0001] The invention relates to the technical field of rail transit or underground stations, in particular to a large-span composite structural underground station and a construction method thereof. Background technique [0002] Existing underground stations generally adopt the excavated arched tunnel or open-cut rectangular frame structure. For the construction method of the open-cut rectangular structure, the span of the station is small, and there are many structural columns in the middle of the station. On the one hand, it affects the operation and construction. The problem of impact damage to the intermediate structural columns. On the other hand, the use of the station will be affected after the construction is completed. In particular, the intermediate structural columns will affect pedestrians and the arrangement of pedestrian passages in the station, which may cause pedestrians to detour. [0003] In addition, its construction is also very troublesom...
