Embodiment 1

[0040] A piling ship includes a hull and a sliding piling platform, the hull includes a base and an adjustable rotating deck, the base includes a plurality of hollow cavities, the base and the adjustable rotating deck are connected through support columns, the The above-mentioned base is provided with a ballasting and loading device for water, and the said ballasting and loading device is used for pumping or filling water from the hollow cavity, thereby controlling the floating and sinking of the hull,

[0041] The adjustable rotating deck includes a rotating platform, at least 2 rotating supports, and 4 supporting supports. The supporting columns are respectively located in the middle and four corners of the base, and the middle columns are connected to the rotating platform through a pin shaft. The support columns at the four corners are connected to the rotating platform through a hydraulic support system.

[0042] The sliding piling platform is set on the adjustable ro...

Abstract

The invention discloses a hull of a pile driving barge. The hull comprises a base and a deck, wherein the base comprises a plurality of hollow cavities, the base is connected to the deck through support pillars, the base is provided with a pressure unloading and loading device for water, and the pressure unloading and loading deice is used for pumping or filling water from the hollow cavities, so that floating and subsidence of the hull can be controlled. Through a floor type manner, the hull is fixed on a seabed; through design of the support pillars, the influence of offshore sea waves on stability of the hull can be reduced; through the annular hull, stability of the hull can be increased, the weight of the hull is reduced, and high-efficiency floating and subsidence can be implemented.

Description

technical field [0001] The invention relates to the field of hydraulic engineering construction, in particular to a hull of a piling ship. Background technique [0002] The traditional offshore piling ship, floating operation, is completely floating. It only relies on anchoring for positioning. The construction accuracy is greatly affected by sea wind and waves, and it will swing and heave. The positioning accuracy is very rough, so the piling deviation will be relatively large, often within Between 15~25cm. However, since more and more projects require high-precision piling on the seabed, conventional floating operations do not meet the requirements. [0003] In addition, the current fixed piling is mainly supported by long columns. Since the ship has only four small contact surfaces at the bottom of the seabed, when the wind and waves are strong, the hull will also be affected. The piling on the seabed makes the hull not fixed as expected, and the traditional piling shi...
