Base pile pitching type single-pile pile stabilizing frame and pile sinking method

Abstract

The invention relates to a pile stabilizing platform, in particular to a base pile pitching type single-pile pile stabilizing frame. The base pile pitching type single-pile pile stabilizing frame comprises a pile stabilizing truss, and a plurality of pile stabilizing platforms are vertically arranged and mounted on the upper middle portion of the pile stabilizing truss. An anti-sinking plate is fixedly mounted on the lower portion of the pile stabilizing truss, and a pile holding mechanism is arranged on the front portion of a platform body. A plurality of single-pile guide mechanisms are annularly arranged in a pile feeding port in the circumferential direction. Each single-pile guide mechanism comprises a guide roller and a telescopic adjusting device for driving the guide roller to advance. The guide rollers are used for being in lap joint with a single pile to adjust the position of the single pile. The base pile pitching type single-pile pile stabilizing frame has the advantages of being stable and reliable in structure, high in positioning precision, convenient to adjust and control, high in perpendicularity adjusting precision and the like. The invention further discloses apile sinking method adopting the base pile pitching type single-pile pile stabilizing frame. According to the method, the vertical precision of single pile sinking is improved, the pile sinking time is saved, and the pile sinking efficiency is improved.

Description

technical field [0001] The invention relates to a pile-stabilizing platform, in particular to a pile-inserting type single-pile stabilizing frame at the base. The invention also relates to a pile sinking method of a pile-inserted single-pile stabilizer frame at the bottom of the seat. Background technique [0002] Wind energy is a renewable and clean energy source, and wind turbines are usually used to collect wind energy in the prior art. Due to the large available space and strong wind in the sea, more and more wind farms are built on the sea. Most wind turbines in the prior art adopt a single-pile structure, and the single-pile foundation structure is the current international and domestic mainstream offshore wind power foundation structure type, while the domestic single-pile foundation mostly adopts a non-transition flange structure, and its vertical Therefore, when installing a single pile, it is necessary to use pile stabilizing equipment to assist pile sinking to m...

AI Technical Summary

Problems solved by technology

In the process of offshore piling, due to the wide construction area, large work surface, poor construction environment and climatic conditions, according to the conventional measurement and positioning method, the pile position deviation control cannot meet the requirements

If special construction techniques and control measures are not taken, the relative position error of the pile top cannot meet the design requirements
