Abstract
Abstract This invention describes a method and apparatus for anchoring a mechanical pipeline system by attaching it to a plurality of anchor posts which have been positioned in the earth. The anchor posts are provided with means for attaching two tension members to their top end. The pipeline may be anchored in a ditch dug into the earth, or in the earth under an overlying layer of water. A plurality of anchor posts arranged in spaced relation along a line are positioned in the earth. The pipeline is placed on the line over the tops of the anchor posts. A clamp means, adapted to be bent around the pipe, is placed over and around the pipe. The two tension members which are attached to the posts are then locked to the clamp. Thereafter the pipe is locked to the anchor posts by means of the clamps and the tension members.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
140 words
An improved anchoring system for a pipeline to be buried under earth or under water, comprising: a. at least one anchor post positioned in the earth, the top of said post substantially at or below the level at which said pipeline is to be anchored, at least two tension members attached to the top of said post, said post substantially directly under said pipeline; b. clamp means adapted to be placed over and to partially surround said pipe above said at least one post; c. means to position said clamp means over said pipeline; and d. means to attach said tension members to said clamp means, said attaching means comprising a pair of oppositely disposed drum members rotatably secured to the clamp means, each drum having a tension member wound thereon for reeling in and unreeling of the tension members.
Claim 2
Dependent Claim
140 words
An improved anchoring system for a pipeline to be buried under earth or under water, comprising: a. at least one anchor post positioned in the earth, the top of said post substantially at or below the level at which said pipeline is to be anchored, at least two tension members attached to the top of said post, said post substantially directly under said pipeline; b. clamp means adapted to be placed over and to partially surround said pipe above said at least one post; c. means to position said clamp means over said pipeline; and d. means to attach said tension members to said clamp means, said attaching means comprising a pair of oppositely disposed drum members rotatably secured to the clamp means, each drum having a tension member wound thereon for reeling in and unreeling of the tension members.
Claim 3
Dependent Claim
20 words

Claim 4
Dependent Claim
16 words
indicating the magnitude of the applied force, whereby the quality of the anchorage can be determined.
Claim 5
Dependent Claim
16 words
indicating the magnitude of the applied force, whereby the quality of the anchorage can be determined.
