Description

Technical Field

[0001] The utility model relates to the technical field of construction processes, and particularly relates to an offshore pile driving platform that can be freely assembled and adapts to multiple diameter pile types. Background Art

[0002] In recent years, with the progress of technology and the continuous reduction of traditional construction land, more and more projects involve marine tidal flat areas. Pile driving operations in marine tidal flat areas will inevitably be adversely affected by sea winds and waves. During traditional pile driving operations, the pile foundation will shake and become unstable under the action of sea winds and waves when being vertically lifted and driven into the pile. At the same time, the surface of the tidal flat area is mostly silt soil. During the pile driving process of traditional pile driving operations, the pile foundation is prone to tilt and deviate. In view of the deficiencies of traditional pile driving operations in the above-mentioned coastal tidal flat areas, a pile driving platform needs to be set up to reduce the adverse effects of sea winds and waves during the pile driving process, and at the same time has a function of correcting the deviation of the pile foundation vertically, improving the safety, reliability and construction efficiency of offshore pile driving operations.

Bolt holes are provided at the end of the hoop clamp and are fixed to the internal column of the platform bracket by bolts; three sets of hoop clamps are configured for each section of the platform to fix the steel casing.

[0007] Furthermore, the diameter of the steel conduit matches the diameter of the pile foundation. The wall thickness of the conduit is approximately 10 mm, and the length is consistent with the height of each section of the platform support, which is between approximately 1 - 2 meters. The steel conduits are respectively fixed inside the corresponding platforms using hoop clamps.
