Abstract

The invention relates to the technical field of deep-water-area drilled piles and particularly discloses an in-water drilled pile foundation construction system capable of recovering steel protective barrels and a construction method thereof. The system comprises a seaborne drill platform located on the sea surface, a crawler crane, a vibratory hammer, an outer steel protective barrel arranged between a seabed stable geological layer and the seaborne drill platform, an inner steel protective barrel arranged in the outer steel protective barrel, a drill bit arranged in the inner steel protective barrel and a slurry pump arranged on the seaborne drill platform, wherein the crawler crane and the vibratory hammer are arranged on the seaborne drill platform, a counter-force frame and a jack are arranged between a top opening of the inner steel protective barrel and the seaborne drill platform, and the drill bit is connected with the vibratory hammer through the crawler crane. The problem that deep-water-area drilled pile steel protective barrels in the prior art cannot be recovered is solved.

Description

technical field [0001] The invention relates to the technical field of bored piles in deep water areas, in particular to an underwater bored pile foundation construction system and a construction method thereof that can recover steel casings when implementing bored piles in deep water areas below sea level. Background technique [0002] The steel casing plays a vital role in the whole process of bored pile foundation construction in water, and determines the quality of the pile foundation. Generally speaking, the steel casing of the pile foundation of the bridge in the water must pass through the silt cover layer of the sea (river) bed, and be driven into a stable geological rock formation, and it must be ensured that no seepage, mud leakage or reverse flow occurs during the drilling project. The phenomenon of perforation. According to the conventional technology, the steel casing of the underwater pile foundation constructed in the deep water environment is a one-time inve...
