Abstract

The invention discloses a round-tunnel double-layer lane frame structure system and a full-prefabricated construction method thereof. The round-tunnel double-layer lane frame structure system comprises a round tunnel, a prefabricated lower-layer lane component, bases, prefabricated bracket stand columns, prefabricated bracket longitudinal beams and a prefabricated upper-layer lane plate. The full-prefabricated construction method comprises the steps that the round tunnel is formed; the prefabricated lower-layer lane component is fixedly arranged at the bottom of the round tunnel, so that a lower-layer lane frame structure system body is formed; the bases of an upper-layer lane frame structure system body are poured; and the prefabricated bracket stand columns, the prefabricated bracket longitudinal beams and the prefabricated upper-layer lane plate are assembled on the bases in sequence, and the upper-layer lane frame structure system body is formed through splicing. The round-tunnel double-layer lane frame structure system and the full-prefabricated construction method thereof have the advantages that the construction efficiency and construction quality can be improved, construction waste is effectively reduced, energy consumption is reduced, environmental pollution is reduced, the structure stability is high, the anti-seismic property is good, and the durability is good.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a double-layer lane frame structure system of a circular tunnel and a fully prefabricated construction method thereof. Background technique [0002] With the rapid development of cities, the available space on the ground is constantly shrinking, while the population density and the number of cars are increasing, and the development of underground space is constantly increasing. In this context, large-diameter and long-distance shield-tunneling circular tunnels have been widely used in the construction of urban expressways. In the field, a circular tunnel with a diameter greater than 10 meters is called a large diameter. At present, the internal structure of large-diameter shield-tunnel tunnels at home and abroad mostly adopts the double-layer lane structure, and the cast-in-place construction technology is the main method. The traditional construction technology has...
