Abstract
Abstract The invention concerns an arrangement for distending sections of the distending body of an earth anchor in sticky soil and in multiple sections and comprises conveying conduit means with an end embedded in the distending body below earth level and an airside end extending above the distending body for supplying slurry to the distending body below earth level and means above the earth level for supplying the slurry to the conduit means, where the embedded ends of the conduit means are provided with openings for emitting the slurry that constitutes the distention material and each section comprises two distention conduits connected to the embedded end.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
109 words
Arrangement for distending in multiple sections of the distending body of an earth anchor in sticky soil, comprising conveying conduit means having one end embedded in the distending body below earth level and an air side end extendinG above the distending body for supplying cement slurry or the like to the distending body below the earth level, means above the earth level for supplying cement slurry to said conduit means, said embedded ends of said conduit means having openings for emitting the cement slurry constituting the distention material, each said section comprising two distention conduits connected at said one embedded end, and one-way valve means connecting said distention conduits.
Claim 2
Dependent Claim
109 words
Arrangement for distending in multiple sections of the distending body of an earth anchor in sticky soil, comprising conveying conduit means having one end embedded in the distending body below earth level and an air side end extendinG above the distending body for supplying cement slurry or the like to the distending body below the earth level, means above the earth level for supplying cement slurry to said conduit means, said embedded ends of said conduit means having openings for emitting the cement slurry constituting the distention material, each said section comprising two distention conduits connected at said one embedded end, and one-way valve means connecting said distention conduits.
Claim 3
Dependent Claim
132 words
Arrangement for distending in multiple sections of the distending body of an earth anchor in sticky soil, comprising conveying conduit means having one end embedded in the distending body below earth level and an air side end extending above the distending body for supplying cement slurry or the like to the distending body below the earth level, means above the earth level for supplying cement slurry to said conduit means, said embedded ends of said conduit means having openings for emitting the cement slurry constituting the distention material, each said section comprising two distention conduits connected at said one embedded end, said distention openings being covered by a cuff disposed around a distention conduit, said cuff having a nose defining a valve the ends of which extend radially of the distention conduit.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
72 words
Method for the multiple distention of the distention body of a ground anchor comprising conveying conduit means in multiple sections of a distending body, placing a part of said means below earth level and placing another part of said means above earth level to define an air side end extending above the distending body, distending each section by supplying slurry to each section and thereupon cleaning the conduits by passing liquid therethrough.
