BRIDGE CONSTRUCTION-BASED PREFABRICATED PILE CAP FOUNDATION

WIPO Patent Application WO/2022/142557

A1

A bridge construction-based prefabricated pile cap foundation, comprising a support column (1). Four first recesses (2) are symmetrically formed at the bottom of the support column (1); the inner top walls of the first recesses (2) are hinged with first plates (4) by means of hinges (3); cones (5) are fixedly connected to the upper surfaces of the first plates (4); a platform (6) is fixedly connected to the top of the support column (1); two second recesses (7) are symmetrically formed on two sides of the platform (6); and second plates (8) are slidably connected inside the second recesses (7). The provision of the second recesses (7) allows the second plates (8) to be concealed inside the second recesses (7); the fit connection between first sleeves (21) and second fixing rods (22) can prevent sliding out of the second plates (8) to facilitate the accommodation of the second plates (8); and the provision of the hinges (3) and second sleeves (27) allows the first plates (4) to be turned over to enable the cones (5) to be fitted to the second sleeves (27), thereby reducing the ground and space occupation, thus facilitating the transportation of the prefabricated pile cap foundation.
