Embodiment Construction

[0034] The present invention will be described in detail below in combination with specific embodiments.

[0035] The invention relates to a construction communication system between a new subway line station and an existing station, comprising an existing structural top plate 1 and an existing structural bottom plate 2 of the existing station, and two sides between the existing structural top plate 1 and the existing structural bottom plate 2 A reserved column 3 is provided. Added columns 4 are installed on the part of the existing structural side walls 6 between the reserved columns 3 , and added beams 5 are installed between the tops of the added columns 4 .

[0036] The newly-added beam 5 and the roof 1 of the existing structure are tied by planting bars 11 . The bottom of the newly added column 4 and the base plate 2 of the existing structure are tied through the planting bars 11 . The newly added beam 5 includes two parts between the top of the newly added column 4 and...

Abstract

The invention relates to a construction communication system for a new subway line station and an existing station and a construction method of the construction communication system. The constructioncommunication system structurally comprises an existing structural roof plate and an existing structural bottom plate of the existing station. Reserved columns are arranged between the two sides of the existing structural roof plate and the two sides of the existing structural bottom plate. New columns are arranged between the reserved columns and located at the positions where existing structuralside walls are removed. A new beam is arranged between the tops of the new columns. According to the construction communication system for the new subway line station and the existing station and theconstruction method of the construction communication system, the length of a to-be-removed segment is calculated and checked according the strength in the construction stage, construction is conducted every a segment through a jump hole method, and a temporary steel supporting system is adopted, so that it is ensured that structural deformation generated by internal force redistribution during removal of an existing wall is with a controllable range, and vertical and horizontal displacement of an existing structure is reduced.

Description

technical field [0001] The invention relates to the technical field of underground structure engineering construction, and specifically relates to a construction communication system and a construction method for a new subway line station and an existing station. Background technique [0002] In the construction of urban rail transit, in order to realize the transfer between the new subway line station and the existing line station, it is often necessary to demolish the side wall at the interface of the existing line station to form a transfer station. There are two situations for the connection interface: (a) Beam-column system is reserved at the interface, and temporary reinforced concrete walls are used to block it, and steel bar connectors are reserved for the roof, middle plate, and bottom plate of the original structure. (b) The interface is not reserved, the structural wall is stressed, and it is the main load-bearing wall. In the second case, opening a large area of...
