Abstract

The invention provides an assembled offshore single-pile foundation construction platform. The construction platform can serve as a large single-pile foundation drilling platform or a large single-pile driving stable pile platform, and comprises a stable pile frame, a steel protection cylinder and steel pipe piles; a positioning cylinder is arranged in the center position of the stable pile frame; multiple locking oil cylinders are symmetrically embedded in the upper end and / or the lower end of the positioning cylinder in the peripheral direction; the steel protection cylinder is inserted in the positioning cylinder, and is radially positioned by the locking oil cylinders; multiple mounting sleeves are uniformly and annularly arranged at the external of the positioning cylinder; the mounting sleeves and the positioning cylinder are fixedly connected through radial trusses; the adjacent mounting sleeves are fixedly connected through peripheral trusses; and the steel pipe piles are inserted in the mounting sleeves, and are connected with the mounting sleeves through clamping keys. The construction platform is quickly assembled through a detachable mode without needing offshore welding work, and can be recycled; and more importantly, through unique structural design, the construction platform is high in stability of bearing the wave load.

Description

technical field

[0001] The invention belongs to the technical field of offshore construction equipment, and in particular relates to an assembled offshore single-pile foundation construction platform and a construction process thereof. Background technique

[0002] Large offshore structures are often supported by various pile foundations that extend into the ground, and the construction of pile foundations requires offshore construction platforms. The construction of offshore large single pile foundation construction platform has the following difficulties:

[0003] (1) When the loose layer of the seabed is too thin, after the steel pipe piles of the construction platform are driven into the seabed, they cannot stand in the sea due to the shallow penetration. It is difficult for the existing single-pile foundation construction equipment to construct the construction platform in this case;

[0004] (2) The existing single-pile foundation construction equipment has a long con...
