Detachable multiple cylinder base large bearing capacity suction foundation device

Abstract

The invention discloses a detachable multiple cylinder base large bearing capacity suction foundation device comprising a main anchoring cylinder and wing cylinders. The main anchoring cylinder comprises the cylinder wall, a pumping hole, a hoisting block, anode blocks used for preventing corrosion, T-shaped sliding ways and locking devices. The T-shaped sliding ways are arranged on the outer side of the wall of the main anchoring cylinder; first fixing holes are formed in the tops of the T-shaped sliding ways; sliding rails matched with the T-shaped sliding ways are arranged on the wing cylinders; and the main anchoring cylinder and the wing cylinders are connected through the T-shaped sliding ways arranged on the outer side of the main anchoring cylinder and the sliding rails arranged on the outer sides of the wing cylinders in a matched mode. According to the detachable large bearing capacity suction foundation device, compared with the prior art, through the composite design of the main anchoring cylinder and the wing cylinders, the anchoring soil action area is increased under the situation that the penetration depth is not changed basically, and the actual action area of the suction foundation is effectively increased, so that the bearing and anchoring properties of the suction foundation are improved. After the anchoring target is finished, the main anchoring cylinder and the lateral wing cylinders can be disassembled, and the main anchoring cylinder with high price is recycled to achieve recycling of a suction anchor.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a detachable multi-tube foundation suction foundation device that can effectively improve the mooring bearing capacity. Background technique [0002] With the development and utilization of offshore oil and gas resources, the importance of deep-water mooring foundations has become increasingly prominent. Since the construction and installation costs of deep-water mooring foundations increase with the deepening of water depth, the research and development of mooring systems with low cost and high bearing capacity has become a necessity. Compared with other traditional mooring foundations, the suction foundation has the advantages of simple and convenient installation and insensitivity to water depth, so it has become a deep-water mooring foundation with great potential. At present, the research on suction anchors at home and abroad is mainly concentrated on the single cylinder, ...
