Locking device used between construction pile stabilizing platform and auxiliary piles

Abstract

The invention discloses a locking device used between a construction pile stabilizing platform and auxiliary piles. The construction pile stabilizing platform is provided with a plurality of sleeves for the auxiliary piles to be arranged in the sleeves in a penetrating and one-to-one correspondence mode, the locking device comprises a plurality of stand columns, a plurality of bolts and a plurality of annular plates; the stand columns are installed on the top face of the construction pile stabilizing platform and are arranged around all the auxiliary piles, a plurality of square through holes which are distributed at equal intervals are radially formed in the peripheral surface of each stand column; the bolts are inserted into the square through holes in a one-to-one correspondence manner; and the annular plates are mounted on the peripheral surfaces of the auxiliary piles, and a channel allowing the bolts to be inserted therein is formed between every two annular plates. According to the locking device, the problem of locking between the pile stabilizing platform and the auxiliary piles during single pile foundation construction is effectively solved; and in addition, the locking device has the advantages of simple structure, convenience in operation, good repeatability, low cost and the like.

Description

technical field [0001] The invention relates to a locking device used for construction between a pile stabilization platform and an auxiliary pile. Background technique [0002] In recent years, with the increase of my country's offshore projects, especially the booming wind power industry. Common offshore wind power foundation types at home and abroad include single pile foundation, jacket foundation, high pile cap foundation, gravity foundation and floating foundation, etc. Among them, the single pile foundation has advantages both in technology and in economy, and has been widely used. Applied to offshore wind farms at home and abroad. Super-large steel pipe piles are used as the foundation of single-pile wind turbines, and the verticality of the piles will directly affect the levelness of the foundation ring, which in turn affects the stability of the wind turbine tower structure. Currently, for the control of super-large-diameter single piles, the pile stabilization pl...

AI Technical Summary

Problems solved by technology

[0003] When the single pile foundation stabilized pile platform is in use, the pile stabilized platform and auxiliary piles need to be fixed. At present, rib plate welding is often used for fixing, but rib plate welding at sea has the disadvantages of unstable welding quality, long welding time and low efficiency. and other shortcomings, which affect the position accuracy and verticality of the pile, making it difficult for the construction result of the pile to meet the design requirements.
