Embodiment Construction

[0067] The present invention will be further described below in conjunction with accompanying drawing.

[0068] see first Figure 1 to Figure 5 , the rock-socketed construction process of large-diameter steel pipe inclined piles for offshore wind power high pile cap foundations of the present invention includes the following processes: steel pipe pile sinking, platform load-bearing frame installation, rock-socketed construction platform installation, rock-socketed equipment installation, steel pipe Pile rock-socketed construction and rock-socketed construction platform demolition.

[0069] Before the steel pipe pile sinking process, the steel pipe piles are transported to the steel pipe processing plant and transported to the construction site by a 5000t large barge equipped with a tugboat.

[0070] The pile sinking process of steel pipe piles includes the following steps: piling ship and piling barge station, steel pipe pile inspection and piling, pile lifting, GPS measureme...

Abstract

The invention discloses a rock-socketed construction technology for a large-diameter steel pipe inclined pile of an offshore wind power high-rise pile cap foundation. The technology comprises the following processes of steel pipe pile sinking, platform bearing frame installation, rock-socketed construction platform installation, rock-socketed equipment installation, steel pipe pile rock-socketed construction and rock-socketed construction platform removal. When the platform bearing frame installation process is performed, a platform bearing frame adopts an H-type steel structure or a cap bottom sealing reinforced concrete structure; when the rock-socketed equipment installation process is performed, a drilling machine and an 80 t crawler crane are arranged on a rock-socketed construction platform, and auxiliary facilities including a container, a generator, a slag collecting box and an air compressor and living facilities are arranged; and the steel pipe pile rock-socketed constructionprocess comprises the following steps of hole drilling protection wall slurry mixture ratio test, hole forming, hole cleaning, steel reinforcement cage hoisting, guide pipe lowering installation andconcrete pouring. The rock-socketed construction technology has the advantages that the standardized construction degree is high, the construction safety is well guaranteed, and the construction progress can be greatly improved.

Description

technical field [0001] The invention relates to a rock-socketing construction technology of a large-diameter steel pipe oblique pile for a high pile cap foundation of an offshore wind power plant. Background technique [0002] The structural type of the high pile cap foundation has been maturely used in domestic offshore, intertidal and subtidal offshore wind power projects. Diameter steel pipe inclined piles are used for bearing, and the slope of steel pipe inclined piles is 5:1 or 6:1. Due to the complex marine hydrogeological conditions in the sea area where offshore wind farms are located, the harsh construction conditions at sea, the distribution of rock foundations and seabeds in the geology, and the large fluctuations of the rock surface, the large-diameter steel pipes with high pile cap foundations in most offshore wind farms are oblique The piles need to pass through the medium and slightly weathered rocks for rock-socketing construction after pile sinking. The ro...
