Large and deep excavations are becoming more and more important especially in intra-urban areas, and ground anchors have proven themselves particularly useful in this extremely challenging civil engineering application. Very often, they are the only way to support excavations. Furthermore,anchors are often the most economical solution in comparison to
steel or concrete cross braces: Unrestricted access to the excavation, uninterrupted and obstruction-free crane operation, no risk of buckling and almost limitless options in terms of anchor forces. If required, ground anchors can be removed from the soil after completing civil engineering work in order not to interfere with subsequent site activities. Due to their being an active system, ground anchors are tensioned so that deformations of the excavation
confinement are actively managed. Controlled load application is ensured before excavation is begun so that construction work is safe for all parties involved as well as for adjacent buildings. In excavations where deformations are irrelevant, passive systems such as soil nails or tension piles can be used.
YIDAO 25mm and 32mm Thread bar Anchors are an actively tensioned ground anchor system. Due to the active tensioning, anticipated deformations of the system and deformations at the civil engineering measure are minimized or entirely eliminated. This applies both to temporary structures and permanent tie backs.
