ABSTRACT:
A channel section is of generally U-shaped cross-section and is made from glass fibre reinforced concrete. The section can be thin and light and easily man-handled. In order to provide the section with sufficient rigidity during the setting of a concrete back fill around the section, a framework of reinforcing bars is provided spaced from the reinforced concrete channel member by tie bars. The reinforcing bars and tie bars form a rigid composite structure with the fibre reinforced concrete member which keeps the member rigid while the concrete back fill is drying and which forms a reinforcing structure in the concrete after drying.
