Section 253. — GABIONS AND REVET MATTRESSES

08/01/14– FP-14

Material

253.02 Add the following:

Weathering Agent 725.20

Construction Requirements

253.03 General. Add the following:

Prepare a sample section to match the requirements of this specification and the rock placement in the existing gabion baskets constructed for the ODOT HCRH State Trail: JB Yeon – Moffett Creek Sec located between I-84 M.P. 37.52 and 39.02.

Stain all steel products with a weathering agent in accordance with Section 563.

253.04 Basket Assembly. Delete the first paragraph and substitute with the following:

Furnish welded wire baskets. Do not damage wire coatings during basket assembly, structure erection, cell filling, or backfilling. Rotate the basket panels into position and join the vertical edges with fasteners according to Subsection 253.05. Temporary fasteners may be used for basket assembly if they are supplemented during structure erection with permanent fasteners according to Subsection 253.05.

Fabricate gabions so that the sides, ends, lid and diaphragms can be assembled at the construction site into rectangular baskets of the specified sizes. Dimensions for heights, lengths and widths of gabion baskets will be as indicated on the plans with a tolerance of plus or minus 3 percent. Gabions will be of single unit construction. Connect the base, lid, ends and sides into a single unit or connect one edge of these members to the base section of the gabion in such a manner that strength and flexibility at the point of connection is at least equal to that of the mesh.

The diaphragm material will be of the same mesh and size as the body of the gabions. Furnish the gabion with the necessary diaphragms secured in proper position on the base such that no additional tying at this juncture will be necessary. Assemble the wire mesh panels (base, ends, sides, diaphragms and lid) so strength and flexibility at connections is at least equal to that of a single panel.

253.06 Cell Filling. Delete the last two paragraphs and substitute with the following:

Fill the cells in a row or layer to ensure no cell is filled more than 12 inches above an adjacent cell. Repeat this process until the basket is full and the lid bears the final rock layer. Completely fill cells so that the lid will bear on the rock when it is secured. Secure the lid so that no more than a 1-inch gap remains at any connection.

Secure lid to the sides, ends, and diaphragms according to Subsection 253.05. Make exposed basket surfaces smooth and neat with no sharp rock edges projecting through the wire mesh.

Special Contract Requirements Project: OR PFH 163(19), Historic Columbia River Highway State Trail, Lindsey Creek to Starvation Creek Trailhead

Gabion rows or layers not completed at the end of each shift, will have the last gabion filled with rock tied internally as an end gabion.

Construct gabions to match the character of the rock placement in the approved sample section.
