Abstract

The invention discloses a suction penetrating arc-shaped plate anchor, a mounting tool for the same and a construction method for the same. An anchor body of the arc-shaped plate anchor is arc-shaped, the mounting tool is a negative-pressure bucket with a bottom notch, and the arc-shaped plate anchor is covered on the bottom notch of the negative-pressure bucket and is penetrated into soil by an existing method. After the arc-shaped plate anchor is mounted in place under the action of negative pressure, the arc-shaped plate anchor firstly turns in situ by the aid of the negative-pressure bucket, the buried depth of the arc-shaped plate anchor cannot be decreased under the restraint action of the negative-pressure bucket, the buried position of the arc-shaped plate anchor after turning can be precisely controlled, and the arc-shaped plate anchor has the advantages of convenience in operation and capability of bearing large vertical tensioning loads, complexity of mounting the plate anchor can be reduced, and the negative-pressure bucket mounting depth can be decreased. The plate anchor are restrained to turn in situ into a deeper soil layer, so that bearing capacity of the plate anchor is increased, and the negative-pressure bucket penetrating depth is decreased.

Description

technical field [0001] The invention belongs to the technical field of marine engineering design and construction, and in particular relates to a plate anchor for mooring a deep-water floating marine structure. Background technique [0002] With the exploitation of oil and gas resources, higher requirements are put forward for the deep-water mooring positioning technology of offshore oil production platforms. Based on the consideration of reducing costs and improving mooring efficiency, deep-water mooring has gradually abandoned the traditional catenary mooring, but more and more uses multi-component mooring lines (steel chains, metal cables and synthetic fiber ropes, etc.) tensioned or semi-tensioned mooring system. At this time, the load angle acting on the anchor body generally exceeds the seabed level by more than 30°, and the anchor body needs to bear a large vertical pull-out load. At present, the deep-water mooring foundations that are developing rapidly and widely ...
