Embodiment Construction

[0030] combine Figure 1 to Figure 9 , the preferred embodiments of the present invention will be described in further detail.

[0031] A non-return helical anchor system, the main components involved include a connector 1 and a non-return helical anchor rod 2, three of which are taken as an example in this embodiment.

[0032] The connecting piece 1 is a component that connects each non-return helical anchor rod 2 , and includes a pull ring rod sleeve 11 , an anchor rod sleeve 12 , and a connecting plate 13 . The ring rod sleeve 11 is in the center, and the three anchor rod sleeves 12 are equiangularly distributed on the periphery, and the ring rod sleeve 11 and the anchor rod sleeve 12 are connected by a connecting plate 13 . In this embodiment, the connecting plate 13 is formed by extending outward from the outer bus bar of the pull ring rod sleeve 11, and then connected with each anchor rod sleeve 12, and the angle between two adjacent connecting plates 13 is 60 degrees. ...

Abstract

The invention mainly discloses a non-return screw anchor system, which comprises at least three non-return screw anchor rods and a connecting piece. The connecting piece comprises a pull ring which is arranged in the center of the connecting piece, at least three anchor rod sleeves, and connecting plates which connect the anchor rod sleeves with the center of the connecting piece. The non-return screw anchor rods are sheathed in the anchor rod sleeves. Screw anchor sheets are arranged on the bodies of the anchor rods adjacent to ends. Non-return sheets are hinged along the end edges of the upper parts of the screw anchor sheets. The non-return screw anchor system has the advantages that the pullout-resistant bearing capacity is strong, the existing seabed is not disturbed basically, the landform of the seabed is not changed, environment-friendly construction is realized, and secondary deposition or washing is not caused.

Description

technical field [0001] The invention relates to the technology in the field of marine engineering, in particular to a non-return spiral mooring system. Background technique [0002] In marine underwater engineering, seabed fixation has always been a difficult technical problem. The topography of the seabed is more complex than that of flat land, and seabed fixtures are always involved in submarine construction projects. [0003] Traditional seabed fixing devices are generally relatively simple fixed foundation piles. When the piles are driven into the seabed, there is bound to be a geological structure that destroys the seabed itself. Security risks. At the same time, the traditional pile driving process is complicated and the construction period is long. [0004] In order to solve the above problems, the inventors designed a non-return spiral anchor system, which is fast in construction, safe and stable, and cost-saving. Contents of the invention [0005] The purpose ...
