Problems solved by technology

The traditional fixed pile positioning platform is usually fixed on the sea level with four positioning piles. In deep waters, the length of the positioning piles is further increased, and the stability of the pile stabilization platform itself is insufficient, so it cannot provide sufficient horizontal feedback during the construction process. The force is used to correct the deviation of pile driving, and there is a risk of overturning; in addition, the insertion and extraction of positioning piles on the pile stabilization platform consume a lot of operating time, resulting in insufficient mobility of pile driving operations, and higher requirements for the window period of offshore operations. low work efficiency

Embodiment Construction

[0035] The present invention is described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] This embodiment is used for verticality control of large-diameter single piles during pile sinking construction, such as Figure 1-5 shown. The large-diameter single pile 4 is hoisted and lowered, and passes through the inner space of the pile holding frame 1 and the moon pool at the center of the platform deck 6 from top to bottom, and the bottom of the large-diameter single pile sinks below the seabed to complete the layout before sinking . During pile sinking construction, a hydraulic or static pressure piling hammer 5 is installed on the top of the large-diameter single pile 4, and gradually hammered to make the large-diameter single pile 4 sink into the seabed. The verticality and inclination of the 4 large-diameter single pile bodies are monitored in real time through the inclinometer 15 and the inclinometer 16 arranged on the 4 lar...

Abstract

The invention belongs to the technical field related to ocean engineering construction, and particularly relates to a floating type pile stabilizing platform device based on anchoring positioning control and a pile sinking method. A anchor chain is twisted and pulled through a hydraulic anchor machine, huge horizontal counter force can be provided for righting of a large-diameter single pile, thedirection is easy to control and dynamically adjust, and therefore the active control effect is achieved, and passive control over a traditional fixed pile stabilizing platform is overcome; the floating platform moves through towing and is positioned by the anchoring system, and compared with a fixed platform needing to be driven into a positioning pile, the maneuverability of offshore operation is higher; the floating type platform is suitable for various water depths, the draft of the floating type platform can be changed by adjusting the ballast water amount in the float bowls under different working conditions, particularly, the floating type platform has better stability in a deep sea area, and the safety of offshore construction is guaranteed.

Description

technical field [0001] The invention belongs to the technical field related to marine engineering construction, and in particular relates to a floating pile stabilization platform and a pile sinking method based on mooring positioning control. Background technique [0002] my country is currently in the stage of large-scale development and construction of offshore wind farms, and is gradually developing from offshore waters to deep seas. The power of wind turbines and the diameter of corresponding large-diameter single piles continue to increase. The pile stabilizing positioning platform is often used for verticality control in the process of pile sinking construction, and has a certain ability to correct deviation. During the construction process, firstly, the large-diameter single pile is hoisted to the installation position by the hoisting machine, and the pile holding frame passing through the pile stabilization platform is lowered, and then the pile body is sunk into th...
