SHEET PILE Russian patent published in 2008 - IPC E02D5/02 

FIELD: construction, particularly sheet piles or sheet pile bulkheads used as sheet-pile enclosure members.

SUBSTANCE: sheet pile comprises body with side edges and locking members connected to the side edges. Each locking member is made as male or female part. The body comprises at least two main thin-walled round sector shells connected with each other by side edges. Each thin-walled round sector shell has central angle not exceeding 180°. The body has at least one additional supplementary round sector thin-walled shell having central angle of not more than 180°. Main and additional round sector shells have the same or different dimensions (outer radius, thickness, central angle) and are connected one to another so that chords of adjacent main round sector shells define 30-180° angles. Supplementary round sector shells are located over spans of convex parts defined in main round sector shells to create the second layer of round sector shells. Both locking members to be secured to the body are made as male or female parts.

EFFECT: simplified structure, decreased labor inputs for pile creation and reduced metal consumption along with keeping of load-bearing ability and decreased production costs.
