Device for preventing crack of overbridge on using FRP anchor

摘要

An apparatus for preventing cracks in high-temperature retaining walls using a fiber-reinforced plastic anchor that installs a fiber-reinforced plastic anchor inside the high-temperature retaining wall so that the high-temperature retaining wall is not cracked by an overloaded vehicle is disclosed. The inner surface of the concrete wall forming the retaining wall of the overpass is installed and fixed at regular intervals from the bottom to the upper surface, and the anchor portion constituting the fiber-reinforced plastic anchor is coupled to the latch constituting the connecting portion to the connecting portion. Let's do it. After the anchor roots are coupled to the latches of the connecting portion, the fiber reinforced plastic anchors are coupled to each other by tightening the two anchor roots with clips. The fiber-reinforced plastic anchor is installed on the concrete wall from the bottom, and then the retaining wall is completed by filling the soil.
