[0042] Among them, before the steel pipe column 700 is inserted, the top elevation of the steel pipe column 700 should be calculated based on the bottom elevation of the special-shaped beam. The insertion depth of the steel pipe column 700 should meet the structural force requirements. The steel pipe column 700 uses the locking steel pipe column of the original steel cofferdam with a diameter of 820mm. The insertion depth is calculated based on the geological conditions and the self-weight force of the structure. Positioning measurement is performed before the steel pipe column 700 is inserted, and the verticality requirements should also be met during the insertion process. Install the unloading block 701 above the steel pipe column 700 to facilitate the subsequent elevation adjustment and device unloading.

[0048] After the steel bars are tied on the bottom formwork 500, the steel bars should be inspected and accepted in time. The side formwork can be installed only after the acceptance is qualified. The outer formwork of the side formwork is made the same as the bottom formwork 500, using 5mm steel plate, and the inner formwork of the side formwork is made of wooden formwork.

[0049] After the formwork is erected and the steel bars are tied and accepted, concrete pouring can be carried out. After the concrete is poured, watering should be carried out in time to cure it.

[0050] In some embodiments, the disassembly of the special-shaped beam support system includes the following steps: after the concrete is formed, the side mold is first removed, and then the lowering unloading block 701 is finely adjusted to unload downward, so that the bottom mold 500 is separated from the cast special-shaped beam body, and then the flower stand is dragged outward using a hand winch, and then the bottom mold 500, distribution beam 704, Bailey beam 703, load-bearing beam 702 are disassembled in sequence, and finally the steel pipe column 700 is pulled out. Since the flower stand is modularly set, it can be disassembled module by module during the disassembly process, so it is more convenient to disassemble.

9. A construction method for a special-shaped beam support system, characterized in that: The method for constructing the special-shaped beam support system according to claim 8 comprises the following steps: Installation of steel pipe columns: insert two rows of steel pipe columns between two adjacent piers; Installation of load-bearing beams: Both ends of each load-bearing beam are fixedly connected to the load-bearing beams on two adjacent steel pipe columns, and each load-bearing beam is laterally spaced between the two piers; Bailey beam installation: install the Bailey beam on each load-bearing beam, fix the Bailey beam to the load-bearing beam, and connect each Bailey beam horizontally through channel steel; Distribution beam installation: multiple distribution beams are laid on the Bailey beam, and each distribution beam is arranged at intervals along the length direction of the Bailey beam; Installation of flower racks: hang each middle support frame on the distribution beam and arrange them at intervals along the second direction, then hang each modeling support frame on both sides of the middle support frame and arrange them at intervals along the second direction, connect the first bottom longitudinal beam with the second bottom longitudinal beam through the first connecting beam, connect the first vertical support with the second vertical support beam through the first connecting beam, and build two left-right symmetrical flower racks on the distribution beam in this way, so that the first top connecting plates of the two flower racks are aligned along the first direction, the first bottom connecting plates of the two flower racks are aligned along the first direction, the second top connecting plates of the two flower racks are aligned along the first direction, and the second bottom connecting plates of the two flower racks are aligned along the first direction, then connect the first top connecting plates of the two flower racks by bolts, connect the first bottom connecting plates of the two flower racks by bolts, connect the second top connecting plates of the two flower racks by bolts, and connect the second bottom connecting plates of the two flower racks by bolts; Installation of bottom mold: Build steel plates on the middle support frame and the modeling support frame of the flower stand to form the bottom mold; Rebar binding: tie the reinforcement bracket on the bottom formwork according to the structure of the special-shaped beam; Installation of side formwork: Build steel plates on both sides of the steel support to form side formwork, so that the steel plates of the side formwork and the steel plates of the bottom formwork together enclose a concrete pouring cavity surrounding the steel support; Concrete pouring: pouring concrete in the concrete pouring cavity; Disassembly of the special-shaped beam support system: disassemble the special-shaped beam support system after the concrete solidifies.

10. The construction method of the special-shaped beam support system according to claim 9, characterized in that: The disassembly of the special-shaped beam support system includes the following steps: After the concrete is formed, the side formwork is removed first, and then the lowering unloading block is slightly adjusted to unload the load downward so that the bottom formwork is separated from the cast beam body, and then the flower stand is dragged out using a hand winch. After that, the bottom formwork, distribution beam, Bailey beam, load-bearing beam are dismantled in turn, and finally the steel pipe column is pulled out.
