Abstract

The invention discloses a stacking shield modular steel support reinforcement structure capable of being installed and disassembled quickly. An annular I-shaped steel main support is arranged on the inner side of a the lower shield tunnel segment; the annular I-shaped steel main support is in an annular shape, and is composed of a plurality of arc-shaped annular I-shaped steel supports; two top end modules are connected with each other through the annular I-shaped steel supports and a first horizontal steel support which are corresponding to the two top end modules; two bottom end modules areconnected by the other annular I-shaped steel support; the two top end modules and the two bottom end modules are in one-to-one correspondence; and the corresponding top end module and the bottom endmodule are connected by another annular I-shaped steel support and vertical steel supports. The stacking shield modular steel support reinforced structure capable of being installed and disassembled quickly can provide reliable support and reinforcement measures for the lower shield, through the modular design of a steel support reinforcement system, the on-site operation procedures are simplified, and the beneficial effects of rapid installation and disassembly of the steel supports are realized.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to a stacked shield modular steel support reinforcement structure that can be quickly installed and disassembled. Background technique [0002] In the construction of subways in crowded cities, the direction of the lines is often restricted by buildings such as high-rise buildings, viaduct piles, street crossing tunnels, and existing pipelines, so various schemes have to be adopted to increase the difficulty and risk of construction. Due to the limited width of underground space, or the construction of multiple subway lines, there are more and more overlapping subway sections in Beijing, Tianjin, Shanghai and other cities. In the overlapping section, no matter whether the upper tunnel or the lower tunnel is constructed first, the later construction will have an impact on the structure of the earlier construction. First up and then down construction, the disturbance of t...
