Open cut station with station middle plate structure as damper and construction method thereof

Abstract

The invention discloses an open cut station with a station middle plate structure as a damper and a construction method thereof. A frame structure of the station comprises a top plate, a bottom plate and an outer wall. The top plate is provided with a high-strength sling at the position of each top plate longitudinal beam; a middle plate cross beam is arranged between the two corresponding top plate longitudinal beams or between the top plate longitudinal beams and the outer wall; the two ends of each middle plate cross beam are connected with the corresponding high-strength slings respectively; the middle plate cross beams are hung on the top plate through the corresponding high-strength slings; and a gap is reserved between each middle plate and another adjacent middle plate or between the middle plate and the outer wall. During construction, the high-strength slings are reserved at the positions, corresponding to side walls or the outer walls on the two sides of each middle plate, of the longitudinal beams of the top plate; then, the middle plate cross beams are arranged between the two corresponding top plate longitudinal beams or between the top plate longitudinal beams and the outer wall; and finally, the high-strength slings are hidden through building decoration. According to the open cut station with the station middle plate structure as the damper and the construction method thereof, the anti-seismic performance of a whole station structure can be effectively improved at low cost, and industrial technical progress is promoted.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of subway stations, in particular to an open-cut station using the mid-slab structure of the station as a damper and a construction method thereof. Background technique [0002] Earthquake disaster is a kind of natural disaster which is very harmful to the subway. [0003] In the existing technology, for the seismic design of subway stations, more "strong seismic" technical measures are adopted, that is, to increase the seismic bearing capacity of the structure by enlarging the section of the station components and adding reinforcement. larger. [0004] Therefore, how to make the subway station resistant to strong earthquakes at a lower cost has become an urgent technical problem for those skilled in the art. Contents of the invention [0005] In view of the above-mentioned defects of the prior art, the present invention provides an open-cut station and its construction method using the ...
