East Texas Anchor Project-36" Pipeline

Latest anchor project includes a 36-inch pipeline located in east Texas. Work included a soil survey that consisted of using a Cat 330 backhoe to pull test anchors in areas requiring buoyancy control. Anchors were installed on a spacing of 50-feet and pull tested at 12,000 lbs. per anchor or 24,000 lbs. per set. The spacing of 50-feet eliminated 5 concrete set-on weights weighing 9,000 lbs. each. Since the installed cost of set-on weights and auger anchors was approximately the same, the cost savings using auger anchors was $4,000.00 per anchor. This project required 320 auger anchors and saved the pipeline company a total of $1,280,000.00.

In addition to the cost savings, the pipeline company received a documented engineered anchor system. As each anchor was installed, the anchor was pull tested and this information was documented along with the station number.
