Abstract
One embodiment of Universal Cellular Cofferdam with embedded prefabricated columnar framing (10), embedded rock anchors (16), pile cap (25), cofferdam perimeter skin (15) and granular fill (22) constitutes a hybrid cofferdam structure comprising columnar framing and cofferdam gravity cell. The described structure utilizes resisting mechanisms of structural framing, cofferdam gravity forces and mechanism of rock anchor devices for creation of unique resisting mechanism where all three resisting mechanisms compliment each other, preventing modes of structural failures typical for gravitational or columnar structures alone.
Claims2
Hybrid gravity-columnar system comprising circular prefabricated columnar space framing;
- perimeter sheet pile infill between the columns of the framing and granular infill confined by a formed barrel herein;
- rock anchors installed and grouted into bedrock and each column annular space, and anchored into the concrete pile cap of the composite framing, forming composite anchored columnar—gravitational system called Universal Cellular Cofferdam herein.
Prefabricated rigid space framing comprising six pipe columns and two horizontal six end star truss diaphragms consisting of two equally sided triangles having all truss elements of the diaphragm intersected and connected in one plan, serving as an integral structural support and lateral bracing for hybrid gravity-columnar system.
