A submarine frame fixed group anchor system

Abstract

The present invention relates to a submarine frame-fixed group anchor system, comprising an anchor frame assembly, the top of which is a hexagonal anchor structure, and a central short cylinder structure arranged in the middle, the central short cylinder structure There are six radial channel steels evenly spaced on the outer peripheral surface of the channel steel, and the head of each radial channel steel is connected with a hollow cylindrical shell, and an upper end cover is installed on the top of each hollow cylindrical shell, and two adjacent hollow cylindrical shells The shells are connected by external channel steel, and six external channel steel are connected to form a hexagonal structure; the bottom of each external channel steel is equipped with a triangular plate, the bottom of each radial channel steel is equipped with a damping plate, and each hollow cylinder The inside of the housing is equipped with a guide post, the bottom of which is provided with a protective sleeve, and the outer circumference of the guide post is symmetrically provided with a first stabbing plate and a second stabbing plate. Works reliably.

Description

technical field [0001] The invention relates to the technical field of group anchor systems, in particular to a submarine frame fixed group anchor system. Background technique [0002] In recent years, in the development of marine and near-shore engineering, the anchoring and positioning technology of floating platforms under the topographic and geological conditions of the near-island reef sea area has become a difficult point in scientific research and engineering, among which the anchor type design suitable for coral facies reef topography and geology is extremely difficult . [0003] Typical near-island reef coral facies geology is composed of calcareous coral sand on the upper layer and cemented reef limestone on the lower layer. There are cracks, collapses and caves in the shallow layer of the reef. The complex engineering geological characteristics have brought new challenges to the anchoring design of the floating platform. challenge. [0004] The traditional gravi...

Problems solved by technology

[0003] Typical near-island reef coral facies geology is composed of calcareous coral sand on the upper layer and cemented reef limestone on the lower layer. There are cracks, collapses and caves in the shallow layer of the reef. The complex engineering geological characteristics have brought new challenges to the anchoring design of the floating platform. challenge

[0004] The traditional gravity anchoring foundation has the disadvantages of large configuration scale and large construction consumables, and the cost of manpower and material resources required for offshore installation is high. The anchoring capacity of typical anchor types in other types of marine engineering in reef seabed is relatively low Low, poor installability

[0005] With the development of technology and the improvement of engineering requirements, the design of new anchors suitable for topographic and geological conditions in sea areas near islands and reefs has become a trend of technological development. The submarine frame fixed group anchor designed based on the concept of embedded structure and multi-body group anchor system, with excellent performance and applicability, there is no similar design scheme of new anchor type near islands and reefs at home and abroad
