Problems solved by technology

[0003] The present invention overcomes the shortcomings in the prior art and aims to design a hydraulic impact torpedo anchor. By adding a hydraulic impactor in the anchor body, it provides power for the torpedo anchor to penetrate into the formation, thereby overcoming the large mass of the existing torpedo anchor. , large volume, inaccurate orientation, and low installation efficiency on sandy and hard-crusted seabeds, to realize the vertical penetration of the torpedo anchor, improve its pull-out resistance and bearing capacity, and this torpedo anchor is small in mass and volume, greatly Facilitate transportation, installation and recycling, and improve work efficiency

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0024] As shown in the figure, a hydraulic impact torpedo anchor is composed of an anchor head 18, an anchor body 19, an anchor chain, and a hydraulic impactor. The anchor head is set below the anchor body, and the anchor chain is divided into outer anchor chains 20 And the inner anchor chain 22, the outer anchor chain is tied to both sides of the anchor head, and the inner anchor chain is tied to the upper part of the anchor body. The anchor body is cylindrical and divided into an inner shell 3 and an outer shell 2. The upper end of the inner shell structure is open Connected to the water inlet pipe of the hydraulic pipeline 21, the space between the inner shell and the outer shell is called the liquid flow channel 15. The liquid flow channel is connected to the return pipe of the hydraulic pipeline, and a communication hole 9 is provided at the bott...

Abstract

The invention discloses a hydraulic impact torpedo anchor. The hydraulic impact torpedo anchor has the advantages that a hydraulic impactor is additionally arranged in an anchor body, power can be provided for the hydraulic impact torpedo anchor for penetrating strata, and accordingly the shortcomings of heavy weights, large volumes and inaccurate orientation of existing torpedo anchors, low efficiency when the existing torpedo anchors are mounted on sandy sea beds on overlaying crusts and the like can be overcome; the hydraulic impact torpedo anchor can perpendicularly penetrate the strata, and the anti-pull performance and the bearing capacity of the hydraulic impact torpedo anchor can be improved; the hydraulic impact torpedo anchor is light and small, accordingly, transportation mounting and recycling work can be facilitated to a great extent, and the work efficiency can be enhanced.

Description

Technical field [0001] The invention relates to a design method for a mooring foundation of an ocean platform, in particular to a hydraulic impact torpedo anchor. Background technique [0002] With the development of offshore oil and gas resource exploration and exploitation to the deep sea, floating or semi-submersible offshore platforms are widely used. In order to ensure the stability of the platform during operation, a tight-leg mooring system has emerged. Among the existing anchored mooring foundations, suction caisson anchors, normal load-bearing anchors, suction flat anchors, and torpedo anchors have all had successful engineering examples and accumulated rich successful experience. Among the above-mentioned anchored mooring foundations, torpedo anchors are considered to be the most promising mooring foundation suitable for deep waters due to their low cost, convenient installation, and high uplift bearing capacity. Torpedo anchors, also known as deep-water penetration an...
