Description

Technical Field

[0001] The present invention belongs to the technical field of bridge engineering construction equipment, and relates to a reversible pile-holding trolley device and a pile foundation transfer construction method. Background Art

[0002] In bridge projects such as sea-crossing bridges, river-crossing bridges, and river-crossing highways, the trestle pile driver can be used to build temporary steel trestles to provide support and work platforms for subsequent pier construction. It can also serve as a material transportation channel and a construction work platform. After construction is completed, it can be disassembled and recycled. Due to the diversity of the outer diameter and length of the pile foundation, the flipping and guiding of the pile foundation become inevitable problems.

[0003] The trestle integrated machine can also transport and install pile foundations using traditional trolleys. However, when the pile foundation is transported to the designated location, manual operation is required to flip it from a horizontal state to a vertical state. This requires a large number of construction workers to operate, which is time-consuming and unsafe. Summary of the Invention
