Post-pile method skirt pile type guide tube frame and steel tube pile temporary locking device and method

Abstract

The invention discloses a post-pile method skirt pile type guide tube frame and a steel tube pile temporary locking device and method. The temporary locking device comprises a horizontal locking assembly and a vertical locking assembly, wherein a guide tube frame skirt pile and a steel tube pile arranged in the skirt pile are horizontally connected through the horizontal locking assembly, and theskirt pile and the steel tube pile are connected in the vertical direction through the vertical locking assembly. The method for temporarily locking the post-pile skirt pile type guide tube frame andthe steel tube pile comprises the following steps of lowering the guide tube frame to a seabed surface, and performing pile inserting, piling and leveling on the steel tube pile after basically leveling; horizontally locking the guide tube frame skirt pile and the steel tube pile arranged in the skirt pile by adopting the horizontal locking assembly; and locking the skirt pile and the steel tube pile in the vertical direction by adopting the vertical locking assembly. According to the device and method, the guide tube frame and the steel tube pile can be temporarily locked, so that the grouting quality of the circular seam between the guide tube frame and the steel tube pile is ensured.

Description

technical field [0001] The present application relates to a temporary locking device and method between a skirt pile jacket and a steel pipe pile, wherein the skirt pile jacket can be used for wind turbine foundations, offshore booster station foundations, offshore platform foundations, and the like. Background technique [0002] The jacket structure is one of the main types of foundation structures for offshore wind turbine foundations, offshore booster station foundations and offshore oil production platform foundations. Jacket installation construction technology is divided into two kinds of technology: first pile method and second pile method. The pile-first method jacket uses an auxiliary platform for positioning and sinking piles, and then carries out the overall hoisting of the jacket foundation. Leveling by hydraulic means and finally underwater grouting to connect the jacket and steel pipe piles. The post pile method jacket foundation structure type is to set skir...

AI Technical Summary

Problems solved by technology

However, for the relative displacement of the jacket and the steel pipe pile that may occur due to the weight of the jacket and the erosion of the mud surface before or during the grouting process, the strength of the grouting material in the annular joint after the grouting does not meet a certain requirement due to external environmental factors such as wind and waves. , flow and other influences may cause relative displacement, which will seriously affect the grouting quality of the annular joint between the jacket and steel pipe piles
