The invention discloses a
structural system for flatly prefabricating and modularly transporting a large-scale
immersed tube tunnel tube section. The
structural system for flatly prefabricating and modularly transporting the large-scale
immersed tube tunnel tube section comprises a
land area prefabrication platform, a modular transportation platform, and an ultra-large type
pipe section transportation
barge, wherein the
land area prefabrication platform comprises a bottom steel plate for supporting the tunnel tube section and multiple rows of support pillars; the tunnel tube section is transported by land through the
land area prefabrication platform; the modular transportation platform is used for sending the tunnel tube section to the transportation
barge and then retreating, is capableof automatically adjusting the height, and comprises multiple communicated transportation modules; the transportation modules are arranged on the bottom part of the bottom steel plate and are locatedbetween the adjacent support pillars; and the ultra-large type
pipe section transportation
barge is used for transporting the tunnel tube section in a
water area. According to the
structural system for flatly prefabricating and modularly transporting the large-scale
immersed tube tunnel tube section provided by the invention, a
dry dock has no need to be built, so that the input of an immersed tube
tunnel construction temporary project is reduced, the immersed tube tunnel cost and the construction period are saved; the requirement on the floor space required for tube section prefabrication issmall, so that the applicability of the immersed tube tunnel is higher; the tube section is transferred through the modular transportation platform, so that the transportation
modes are flexible; andthe requirement on the fairway depth is low, so that the dredging of an existing fairway can be avoided or reduced.
