Description

Technical Field

[0001] This utility model relates to the technical field of precast pier construction equipment, and in particular to a precast pier platform. Background Technology

[0002] Bridge piers are crucial components in bridge structures, connecting the upper and lower sections. Currently, precast bridge piers are widely used in various bridge construction projects due to their advantages such as energy efficiency, environmental friendliness, reliable quality, and low labor requirements.

[0003] Currently, during the prefabrication of piers, piers with different cross-sectional dimensions require the use of pier bottom molds of different sizes and specifications. However, in most cases, the same prefabrication plant needs to produce piers with multiple cross-sectional dimensions.

[0004] Traditional construction methods involve first constructing two layers of enlarged foundations underground and pre-embedding anchor bolts for later fixing of the steel base. This results in fixed positions for the precast pedestals, a large investment, and a lack of technical flexibility to adjust them according to the specifications of the piers. Utility Model Content
