Embodiment 1

[0042] A gravity penetrating deepwater anchor, comprising an anchor body 1, and an anchor member installed on the anchor body;

[0043] The anchor includes a tray 11, a supporting plate 8, a strut 14, and a connecting member;

[0044] The anchor is provided with a tray channel 16 for the tray to move in the axial direction, an anchor body channel 18 for the anchor cable 2 to be installed, and a groove 15 for the strut to be placed in the axial direction, and the lower end of the anchor cable passes through the anchor body channel. And connected with the tray;

[0045] The tray is set on the lower part of the anchor body and slides with it through the tray channel. There are several supporting plates and grooves evenly distributed on the upper side of the tray. The lower end of the supporting plate is hinged with the tray. Rotate, the support plate and the support rod are set in one-to-one correspondence, and the upper and lower ends of the support rod are respectively hinged ...

Embodiment 2

[0060] In order to further strengthen the anchor body, on the basis of Embodiment 1, a gap 10 is provided between adjacent supporting plates, and a geomembrane 20 is arranged in the gap, and adjacent supporting plates are connected through a geomembrane. In the initial state, The geomembrane is in a folded state; the geomembrane can be opened correspondingly with the expansion of the supporting plate and embedded in the soil.

[0061] In this embodiment, flexible steel wires are arranged on the outside of the geomembrane in the gap, and adjacent supporting plates are connected by flexible steel wires. In the initial state, the flexible steel wires are in a folded state; Correspondingly, the geomembrane in the unfolded state is expanded to carry out load-bearing reinforcement.

[0062] In this embodiment, an opening 21 connected to the channel of the anchor body can be provided on the anchor body above the channel of the tray, and the upper end of the channel of the anchor body...

Abstract

The invention relates to a gravity penetration type deepwater anchor and a construction method, the gravity penetration type deepwater anchor comprises an anchor body and an anchoring part installed on the anchor body, and the anchoring part comprises a tray, a supporting plate and a supporting rod; a tray channel allowing the tray to move in the axial direction, an anchor body channel allowing the anchor cable to be installed and a groove allowing the supporting rod to be placed are formed in the anchoring part, and the lower end of the anchor cable penetrates through the anchor body channel and is connected with the tray; the tray is sleeved on the lower portion of the anchor body and is in sliding fit with the anchor body through a tray channel, the supporting plates and the grooves are evenly distributed on the circumference of the upper side of the tray, the lower ends of the supporting plates are hinged to the tray, the supporting plates and the supporting rods are arranged in a one-to-one correspondence mode, and the upper ends and the lower ends of the supporting rods are hinged to the anchor body and the supporting plates respectively. In an initial state, the supporting rod is contained in the groove of the anchor body, the supporting plate surrounds the periphery of the anchor body, according to the gravity penetration type deepwater anchor, the anchor body is installed into soil by means of the characteristics of a torpedo anchor, then the supporting plate is embedded into the soil by means of a dragging method similar to that when a normal bearing anchor is installed, and the anchor body which is inversely buckled in the soil body is formed.

Description

technical field [0001] The invention relates to the field of deep underwater permanent anchoring, in particular to a gravity penetration deepwater anchor and a construction method. Background technique [0002] Due to the shortage of resources, more and more offshore platforms are turning to deep sea. However, it is extremely difficult to use fixed offshore platforms in deep sea, so floating structure platforms are used. These floating structures need to be fixed in a certain position by mooring devices during their service. At present, relatively mature mooring devices in deep water areas include: bucket suction anchor, normal bearing anchor, suction penetration plate anchor, and torpedo anchor. [0003] Among them, the torpedo anchor has been favored by many due to its advantages of quick installation, low cost, and no need for additional energy. The principle of the torpedo anchor is: release it at a predetermined height above the seabed, relying on its own weight and k...
