0 # block bracket

The applicable scenarios for the 0 # block bracket include: 1) High pier and large-span bridge engineering ① Continuous rigid frame bridge and high pier structure Suitable for continuous rigid frame bridges with pier heights exceeding 100 meters, it replaces traditional full frame brackets and solves the problem of difficult bracket installation during high pier construction. ② Construction of large-span continuous beams Suitable for continuous beams with spans exceeding 70 meters, such as 72 meters+135 meters+72 meters large-span structures, the stability of cantilever casting is guaranteed through a triangular bracket support system. 2) Complex terrain and restricted construction areas ① Cross traffic arteries and navigable rivers When crossing highways, railways, or navigable rivers, the bracket can rely on the pier body to form a support system, avoiding interruption of ground traffic or navigation. ② Canyon and steep slope terrain Suitable for areas with difficulty in erecting supports such as deep valleys and steep slopes, it achieves unsupported construction through embedded parts and anchoring devices, reducing dependence on the foundation. 3) Special process requirement scenario ① Large volume concrete pouring For the 0 # block with a concrete volume exceeding 300 cubic meters (weighing approximately 1022 tons), a staged pouring process is adopted to reduce cracks and improve structural durability. ② Complex cross-sections and irregular structures Adapt to complex cross-sections such as single box three room and variable cross-section box beams, and meet the requirements of prestressed pipeline positioning and high-precision construction through customized bracket design. 4) Urban and economic demand scenarios ① Urban Interchange Hub Project In urban overpasses or comprehensive hubs, prefabricated triangular brackets can be quickly assembled, reducing construction land occupation and traffic interference. ② Low cost and efficient construction By adopting a leasing model and modular design, construction costs have been reduced, key line construction periods have been shortened by up to 60 days, and overall work efficiency has been improved by over 20%. Note: In practical applications, the safety of bracket anchoring needs to be verified in conjunction with the bearing capacity of the pier body. For example, pre embedded holes need to be filled with concrete of the same grade and sealed to avoid affecting the appearance quality of the pier column.
