The tension apparatus and gauge
An update on the hillside retaining project we previously talked about. You may recall, our client contacted us because she was losing parts of her yard to landslides during heavy rains. We design a retaining system to stop the process. It involved driving about 80 pipe piles, held back by two rows of about 20+ tiebacks, each with a resisting tension of 4,000 to 6,0000 pounds. Each anchor has to be tested to a proof load of double the design load. These guys are getting very dirty.
This anchor was stressed with 12,000 lb force.
