An insulated carrier pipe enclosed within a protective jacket rests directly upon a curved bolster embedded in a compacted sand bed. Stainless steel bands wrap tightly around the bolster and jacket assembly to secure the carrier pipe in position. Cross sections and isometric views illustrate the relative placement of the carrier pipe, jacket, bolster, and restraining bands within the trench bed.
