Abstract
Abstract An underwater pipe anchoring device is adapted to be connected to an anchor for anchoring the pipe to underwater strata. A first support section is shaped to engage a first portion of the outer surface of the pipe and a second support section is shaped to engage a second portion of the outer surface of the pipe. A hinge connects an end of the second support section to the first support section so that the second support section can swing into and out of a position where the support sections surround the pipe and engage opposite sides of the outer surface of the pipe. The end of the second support section opposite the hinge is releasably connected to the first support section so that the support sections can be connected for supporting the pipe. Metal-to-metal contact between the support sections and pipe is prevented for protecting the pipe.

Claim 1
Independent Claim
278 words
Pipeline anchoring device for anchoring a pipe to underground strata, comprising: (a) a first support section shaped to engage a first portion of the outer surface of the pipe; (b) a second support section shaped to engage a second portion of the outer surface of the pipe; (c) hinge means for connecting a portion of the second support section to the first support section on one side of the pipe so that the second support section can swing into and out of a position where the support sections surround the pipe and engage opposite sides of the outer surface of the pipe; (d) means for releasably connecting a portion of the second support section on the other side of the pipe from the hinge means to the first support section so that the support sections can be connected for supporting the pipe; and (e) one of the support sections including at least one portion projecting outwardly away from the pipe and an opening in said portion; and (f) anchor means including at least one elongated rod adapted to be driven into and become anchored in underground strata, an upper drive head on said rod of smaller cross-sectional dimensions than said opening, a drive coupling adapted to fit over the drive head, lower bearing means larger than at least part of said opening connected to the coupling for engaging and holding the lower surface of the said portion, upper bearing means larger than at least part of said opening and including an opening through which the drive coupling can project, and lock means for preventing the drive coupling from moving downward through the opening in said upper bearing means.

Pipeline anchoring device for anchoring a pipe to underground strata, comprising: (a) a first support section shaped to engage a first portion of the outer surface of the pipe; (b) a second support section shaped to engage a second portion of the outer surface of the pipe; (c) hinge means for connecting a portion of the second support section to the first support section on one side of the pipe so that the second support section can swing into and out of a position where the support sections surround the pipe and engage opposite sides of the outer surface of the pipe; (d) means for releasably connecting a portion of the second support section on the other side of the pipe from the hinge means to the first support section so that the support sections can be connected for supporting the pipe; and (e) one of the support sections including at least one portion projecting outwardly away from the pipe and an opening in said portion; and (f) anchor means including at least one elongated rod adapted to be driven into and become anchored in underground strata, an upper drive head on said rod of smaller cross-sectional dimensions than said opening, a drive coupling adapted to fit over the drive head, lower bearing means larger than at least part of said opening connected to the coupling for engaging and holding the lower surface of the said portion, upper bearing means larger than at least part of said opening and including an opening through which the drive coupling can project, and lock means for preventing the drive coupling from moving downward through the opening in said upper bearing means.
Claim 3
Dependent Claim
20 words
The device of claim 1, wherein the support sections are shaped to conform to the outer surface of the pipe.
Claim 4
Dependent Claim
27 words
The device of claim 1, wherein the lock means includes a bolt projecting through the drive coupling and drive head and a nut threadedly engaging the bolt.
Claim 5
Dependent Claim
43 words
The device of claim 1, wherein the hinge means includes a downwardly-facing U-shaped member connected to the projecting portion, a sleeve connected to the second support section, and a bolt engaging the two legs of the U-shaped member and projecting through the sleeve.
Claim 6
Dependent Claim
40 words
The device of claim 1, wherein the hinge includes a downwardly-facing U-shaped member mounted for lateral movement on the projection portion, a rod engaging the two legs of the U-shaped member, the second support section being connected to the rod.
Claim 7
Dependent Claim
88 words
The device of claim 5, wherein the means for releasably connecting includes a lateral projection formed on the second support section, said lateral projection and a cooperating projecting portion of the first support section including corresponding openings when the sections engage each other, and a bolt means connected to the second support section capable of projecting through the openings and joining the sections together when the support sections surround the pipe, the opening in the cooperating projecting portion being elongated to accommodate lateral movement of the U-shaped member.
Claim 8
Dependent Claim
42 words
The anchoring device of claims 1, and further including means for preventing metal-to-metal contact between the support sections and pipe for protecting the pipe and not interrupting the cathodic protection for the pipe when said anchoring device is adapted for use underwater.
Claim 9
Dependent Claim
22 words
